1. Definitions
1.1. Contractor means “BUSINESS TECH” LLC, operating under the OneBusiness brand. Customer means the individual, individual entrepreneur or legal entity identified in the Invoice. Together they are the Parties.
1.2. Offer means these service terms. Invoice means the payment request issued by the Contractor containing individual terms. The Agreement comprises the version of the Offer accepted by the Customer, the Invoice, and the annexes and amendments agreed by the Parties.
1.3. Work Chat means the individual Telegram chat agreed in writing for the Customer’s services. Business Day means Monday to Friday, excluding non-working public holidays in Armenia. Banking Day means a day on which the servicing banks process the relevant payments. Times are Yerevan time.
1.4. Consumer means an individual acquiring services outside their trade, business, craft or profession. Consumer status depends on the actual purpose of the services, not merely on the designation used in the Invoice.

2. General provisions
2.1. The Contractor offers to enter into an agreement for services for consideration on the terms of this Offer and the relevant Invoice. Before payment, the Customer receives the full applicable version and individual terms in a form that can be retained unchanged.
2.2. Mandatory law prevails. Terms on liability limits, acceptance, refunds, payment and termination do not apply to the extent that they impair mandatory consumer rights or other rights that cannot lawfully be restricted.
2.3. Before acceptance, the Customer states the purpose of the services and provides information necessary to determine their status. An incorrect designation does not by itself deprive a person of statutory protection.

3. Subject matter
3.1. The Contractor provides, and the Customer accepts and pays for, agreed registration, corporate, accounting, tax, HR, legal and other services. Section 4 describes available services; it does not include every listed activity in every package.
3.2. The Invoice and agreed task define the package, volume limits, service period, deliverables, deadlines and price. Restoration of earlier accounting records, correction of pre-existing breaches and unfinished matters of another provider require express agreement.
3.3. Activities requiring professional status, a licence, admission or a power of attorney are performed only by duly qualified and authorized persons. This Offer does not itself replace a power of attorney, an agreement for advocate services or another mandatory special document.

4. OneBusiness service catalogue
4.1. Registration and corporate services: preparation and support of state registration of legal entities and individual entrepreneurs; obtaining registration documents and extracts; registration of changes to directors, participants, constitutional documents, addresses, activities and capital; governing-body resolutions and minutes; reorganization and liquidation support; preparation of powers of attorney; bank-account opening support, banking document packages and responses to bank inquiries.
4.2. Legal services: oral and written advice; legal analysis of business models and transactions; drafting, review and negotiation of service, supply, works, lease, sale, agency, commission, loan and confidentiality contracts, corporate agreements, offers, policies and user documents; claims, responses, demands, notices, letters and opinions; corporate support, negotiations and dealings with authorities, banks and counterparties; procedural documents and pre-litigation and court support where separately included; legal review of documents and processes and identification and mitigation of risks.
4.3. Accounting services: accounting setup and maintenance; document workflows; processing source documents; accounting for income, expenses, banking and cash transactions, counterparty settlements, receivables, payables, fixed assets, intangible assets, goods and inventories; depreciation; agreed stocktaking; payroll and related payments; accounting registers, financial and management reports; documents for banks, auditors and public authorities.
4.4. Tax services: tax-accounting setup and maintenance; calculation of liabilities; declarations, calculations and mandatory reporting, including electronic filing; advice on tax regimes and transactions; tax-risk analysis; explanations and documents for tax authorities; support during tax audits and control procedures where separately included.
4.5. HR services: personnel-record setup and administration; employment agreements and amendments; documentation of hiring, transfers, changes to employment terms, leave and dismissal; orders, applications and notices; personnel files and registers; timesheets and working-time records; mandatory personnel reporting; employment-law advice, internal employer documents and HR procedures.
4.6. Additional services: applications, letters, inquiries, certificates, powers of attorney and other documents; support for individual projects, transactions and registration, banking, corporate, tax and HR procedures. Services and expenses outside the package require separate agreement before performance or expenditure. A legal review is not a statutory financial audit.

5. Acceptance of the Offer
5.1. Full or partial payment of the Invoice after receipt of the applicable Offer constitutes full and unconditional acceptance. The Agreement is concluded when payment is credited to the Contractor’s account. Partial payment does not reduce the agreed price or change the balance due date. A mistaken payment is not acceptance where there is no intention to contract.
5.2. Before payment, the Contractor sends the Offer as a file or provides a link to a retainable dated version, states the Invoice validity period and allows data to be clarified or corrected. After acceptance and before services begin, it emails the Customer confirmation of the Agreement and its terms.
5.3. A third-party payment constitutes performance for, and acceptance on behalf of, the Customer identified in the Invoice only where the Customer’s instruction or subsequent approval is established. Payment alone does not make the payer the Customer. The Contractor may request the payment purpose, authority and legally required documents.
5.4. A Customer who disagrees with the terms must request an individual agreement before payment. Payment for a further period under an existing Agreement does not by itself signify acceptance of revised general terms.

6. Invoice and individual terms
6.1. The Invoice states its number and date, the Parties’ details and contacts, service scope and volume, period, deliverables or task reference, price, currency, tax treatment, total payable, payment deadline and method, offer validity and Offer version date. Any referenced package description and limits are provided before acceptance.
6.2. Individual terms on price, scope and timing prevail only to the extent agreed by the Parties. Other departures must expressly identify the term being changed and be confirmed by authorized representatives. Merely issuing an additional Invoice does not create an obligation to pay for an unagreed service.
6.3. An Invoice used as a payment request does not replace a tax invoice, settlement document or other document required by Armenian law. The Contractor issues mandatory documents in the prescribed manner.

7. Task procedure
7.1. Tasks are sent through the Work Chat or agreed email and identify the requested action, source information and any deadline known to the Customer. The Contractor confirms acceptance, the responsible specialist, agreed timing and missing documents. Urgency or sending a message alone does not constitute automatic acceptance of an additional task.
7.2. Recurring duties expressly included in the package are performed without a separate monthly instruction once necessary data and authority are available. The Contractor maintains current-task records and reports material obstacles and approaching deadlines within the agreed services.
7.3. A delay in necessary data or approvals changes a contractual deadline only to the extent that performance is actually affected, allowing reasonable restart time. Statutory, court and administrative deadlines are not extended by this clause. The Contractor promptly warns of a risk of missing them.

8. Contractor obligations
8.1. The Contractor performs the agreed services in good faith, with professional care and compliance with applicable requirements, assigns a responsible specialist and arranges internal review of documents appropriate to the task.
8.2. The Contractor requests missing information in time, reports material inconsistencies and obvious errors it identifies, and delivers results and filing confirmations where filing is included. This does not require an uncommissioned audit or forensic authentication of every document.
8.3. The Contractor may engage staff and subcontractors and replace specialists while maintaining agreed quality, timing and confidentiality. It remains responsible for engaged persons as required by law and the Agreement. Data processors are engaged subject to section 17.

9. Customer obligations
9.1. The Customer pays on time, supplies complete and accurate documents and necessary access and authority, approves drafts and reports relevant changes in activities, employees, management, participants, accounts, transactions and tax status. Known procedural and mandatory deadlines must be disclosed when assigning the task.
9.2. The Customer makes its own business and management decisions. It remains the employer, signs documents within its authority and ensures actual compliance with employment requirements and accurate employee information. The Contractor does not become the employer of the Customer’s staff but remains responsible for its own breaches in providing HR services.
9.3. On a substantiated request, the Customer provides identification, authority, beneficial-ownership, transaction-purpose and source-of-funds information to the extent required by law and the service. Instructions must not require unlawful acts, fictitious documents or concealment of mandatory information.

10. Service guarantees and standards
10.1. The Contractor guarantees proper performance of accepted tasks within the agreed scope, subject to timely provision of necessary data, authority and payment. It explains any obstacles, their effects and available remedies.
10.2. A favorable decision by a court, authority, bank, notary or counterparty, account opening, permit issuance, registration or another outcome dependent on an independent third party is not guaranteed. This does not excuse defective preparation, late filing or any other breach by the Contractor.
10.3. Advice is based on disclosed facts and the applicable law at the date given. Updating one-off advice and ongoing monitoring require separate agreement. This does not remove the duty to account for changes in law when performing current agreed services.

11. Price and payment
11.1. The Invoice states the price and tax treatment, specifying whether VAT is included, added or lawfully inapplicable, and the total payable. No unagreed additional charges are imposed. Mandatory taxes and settlement documents reflect the Contractor’s actual tax status.
11.2. Unless the Invoice states otherwise, recurring services are payable 100% in advance by the third Banking Day of the relevant month. Where services start later, the first payment deadline is stated separately. One-off services are payable by the Invoice deadline. Payment occurs when funds are credited.
11.3. Payments are made in Armenian drams; foreign currency is permitted only as allowed by law. Any lawful currency clause must specify the payment currency, exchange-rate source and conversion date. Each Party bears its own bank’s fees. Any different allocation is agreed before payment and reflected in the Consumer’s total price.
11.4. The Contractor may propose a new price where scope, complexity, transaction or employee volumes or legal requirements change. For recurring services, at least 30 calendar days’ notice is given; a change applies prospectively only after the Customer agrees. Silence is not consent. The Customer may reject the new price and terminate without penalty under section 19; previously agreed services until termination remain payable at the existing price.

12. Late payment and arrears
12.1. Overdue monetary sums bear interest under and within the limits of Article 411 of the Armenian Civil Code, using the applicable rate for the relevant period, unless another lawful rate is agreed. A calculation is provided on request. Interest is not charged on sums that are not due.
12.2. For termination purposes, two months’ arrears means unpaid service fees lawfully due for two completed billing periods, not merely two invoices for future services. If period prices differ, the actual agreed fee for each period applies.
12.3. A dispute over a particular service does not excuse payment for undisputed independent services. Lawful set-off and other remedies remain available. Collection costs are recoverable only if documented, reasonable and permitted by law; litigation costs are allocated under procedural law.

13. Suspension of services
13.1. Where payment or necessary documents, access, authority or approval are overdue, the Contractor may suspend affected services after written notice describing the breach, possible consequences and a cure period of at least 5 Business Days. Suspension is permitted if the breach remains uncured and actually prevents performance.
13.2. Unlawful instructions, an established conflict of interest, a real data-security threat or a mandatory legal prohibition permit immediate suspension of the affected actions. The Customer is notified promptly, except where disclosure is prohibited. A generic reference to “compliance risk” without factual or legal grounds is insufficient.
13.3. The Contractor identifies known upcoming mandatory deadlines and reasonably assists in preventing harm. Relief from liability applies only to consequences causally linked to the Customer’s breach, not to the Contractor’s own delay, defective notice or other breach.
13.4. Suspension does not extinguish an existing lawful debt. Fees do not accrue automatically during complete non-performance; payment covers actual work and any separately agreed service availability actually maintained, to the extent lawful. Resumption and revised deadlines are confirmed promptly after the obstacle is removed.

14. Acceptance, defects and refunds
14.1. Deliverables are sent through the agreed channel in accessible, retainable files. For recurring services, the Contractor sends a period-end report of completed actions and delivered documents. The acceptance period starts on established receipt of the deliverable or report, not on the Invoice date.
14.2. Unless a separate acceptance certificate is required, no reasoned objection within 5 Business Days constitutes acceptance only as to volume and defects apparent on ordinary inspection. It does not establish unperformed services, waive latent-defect claims or shorten statutory remedy periods, including those of Consumers.
14.3. An objection identifies the disputed result, specific non-conformity and requested remedy. Lack of technical legal language is not grounds for rejection. The Contractor corrects defects attributable to it without charge within an agreed reasonable period, normally no more than 10 Business Days unless the correction requires otherwise. Shorter mandatory periods prevail.
14.4. The OneBusiness refund guarantee covers objective non-conformity with agreed scope, quality or timing that has not been properly remedied. The unperformed or defective portion is refunded; where the entire result is unusable for the agreed purpose, the corresponding full price is refunded. Refunds are made within 10 Business Days of acknowledging the claim or settlement; judgments are performed within the applicable judicial or statutory period. Mandatory rights to immediate withdrawal and other remedies remain available; the Contractor’s assessment is not a final determination of the dispute.
14.5. Third-party expenses are excluded from refunds only if agreed in advance, actually incurred, documented, non-recoverable and lawfully deductible. Taxes are adjusted under tax rules, not automatically retained from every refund. Mandatory Consumer refund grounds, amounts and deadlines apply, including section 19.

15. Telegram and electronic communications
15.1. The Work Chat is the primary operational channel. Before services start, the Parties confirm email addresses, the chat identifier and authorized participants in writing. Price or scope changes, termination and debt acknowledgment require authority for that action; chat membership alone does not confer it.
15.2. The Contractor emails notices of arrears, price changes, suspension and termination to the agreed address and duplicates them in the Work Chat. If the chat is unavailable, email remains available. The Customer may send claims or withdrawal notices to info@onebusiness.am; failure to duplicate them in the chat does not invalidate them.
15.3. The legal effect and receipt of communications are determined by law, considering established delivery and availability to the recipient. A screenshot of a sent message alone is not conclusive proof of receipt. Silence, a read indicator or lack of objection alone is not consent to a new price, waiver of a right or acknowledgment of debt.
15.4. The Parties retain material correspondence and documents outside Telegram, secure their accounts and promptly report lost or compromised access. Confidential information is transferred subject to section 17. Private electronic-signature keys and other non-transferable authentication credentials must not be posted in the shared chat.
15.5. Electronic communications may be evidence under applicable law but do not replace mandatory notarization, electronic signatures, original powers of attorney or other prescribed formalities. The Parties execute documents in the required form where necessary.

16. Liability
16.1. Each Party is responsible for its breaches on the grounds prescribed by law. Incomplete or inaccurate data, delayed approvals and unilateral Customer changes are assessed by causation and each Party’s contribution. They do not excuse failure to identify obvious errors that proper performance required the Contractor to identify.
16.2. To the extent lawful, aggregate liability for recurring services is limited to fees actually paid in the 3 months before the breach; if services lasted less than 3 months, the limit is all fees paid for that period. For a one-off task, the limit is its full agreed price. Multiple claims arising from the same breach do not multiply the limit.
16.3. These limits also exclude lost profits and indirect losses. They do not apply to intentional breach, gross negligence, confidentiality or personal-data breaches, mandatory Consumer liability, return of the Customer’s money or documents, full compensation upon the Contractor’s withdrawal under Article 780(2) of the Armenian Civil Code, or any other liability that cannot lawfully be limited.
16.4. Taxes and mandatory payments that the Customer would have owed irrespective of a breach remain its responsibility. Documented fines, late charges and other losses caused by the Contractor’s breach are assessed under general liability rules and applicable limits. The same loss is not recovered twice.

17. Confidentiality and personal data
17.1. The Parties do not disclose non-public commercial, financial, HR or legal information and documents obtained during performance. Disclosure is permitted with lawful authorization, to necessary participants bound by confidentiality, or as required by law. This duty survives termination until the information lawfully becomes public; legally protected secrets remain protected as prescribed by law.
17.2. Data is processed only for agreed services, payments, mandatory reporting and other lawful duties, to the minimum necessary extent and on a basis recognized by Armenian law. The Customer’s acceptance does not replace required consent from employees or other data subjects and does not authorize marketing use.
17.3. For data supplied for services, the Customer determines lawful purposes and the task, and the Contractor acts on written instructions. For its own mandatory accounting and identification duties, the Contractor independently ensures lawful processing. Instructions do not transfer either Party’s mandatory duties to the other.
17.4. Before personal data is transferred, the Parties document instructions specifying legal bases and purposes, data and subject categories, operations, retention periods, recipients and engaged processors, storage locations and transfer countries, security measures and return or deletion procedures. Special-category data requires a separate lawful basis and safeguards. General acceptance of the Offer does not fill unspecified terms.
17.5. The Contractor restricts access to necessary persons and maintains confidentiality commitments, access controls, backups and proportionate technical safeguards. New processors require prior written agreement with the Customer and verification of lawful conditions. The Contractor ensures they comply with the instructions.
17.6. Transfers outside Armenia, including storage in foreign cloud services, are permitted only in compliance with Article 27 of the Armenian Personal Data Protection Law, including adequacy and regulatory-permission requirements where applicable. Consent to use Telegram does not independently authorize every international transfer. Lawful alternative channels are used until requirements are met.
17.7. The Contractor notifies the Customer of data loss, unauthorized access or disclosure without undue delay and no later than 24 hours after discovery, with subsequent updates on circumstances and measures taken. This is a contractual deadline. Mandatory notices to subjects and authorities follow statutory procedures and deadlines, including shorter ones.
17.8. Data is retained no longer than necessary for the agreed purpose or a mandatory statutory period. After return under section 19, working copies are deleted within 30 calendar days and backups in the next cycle, no later than 90 days, except records lawfully retained. The basis and duration of such retention are recorded and access restricted.
17.9. Data subjects receive their statutory rights to information, access, correction, blocking, destruction and complaints. Requests are accepted at info@onebusiness.am; the Contractor assists the Customer and fulfils its own duties. Anti-money-laundering disclosures to competent authorities are made only when legally required, respecting professional secrecy and any applicable prohibition on revealing the report itself.

18. Intellectual property and deliverables
18.1. The Customer’s source documents, data and materials remain its property or that of their lawful right holders. Transfer for processing does not authorize the Contractor to use them outside performance or another lawful basis.
18.2. For specifically prepared and paid deliverables, the Contractor grants a non-exclusive right of use worldwide for the full duration of the relevant rights, with remuneration included in the service fee. Storage, reproduction, modification, business use and provision of necessary copies to employees, advisers, replacement providers, counterparties and authorities for the Customer’s purposes are permitted. This does not permit selling the underlying templates as a separate product.
18.3. Rights in the Contractor’s pre-existing methods, templates, software and knowledge bases are not assigned; their inclusion must not prevent permitted use of a deliverable. Third-party materials are supplied only within available rights. Intellectual-property terms do not justify withholding the Customer’s documents or accounting data.

19. Term, amendment, termination and handover
19.1. The Agreement takes effect upon acceptance. A one-off engagement continues until performance; recurring services run for agreed periods or indefinitely if the Invoice expressly states this. Any renewal procedure is disclosed before acceptance. Lawfully accrued payment obligations, confidentiality and obligations intended to survive remain effective after termination.
19.2. The Customer may withdraw from further performance under Article 780 of the Armenian Civil Code by notifying the Contractor. Termination takes effect on receipt or on a later date specified by the Customer. For recurring-service handover, 30 calendar days’ notice is recommended but is not a condition of exercising the statutory withdrawal right. Properly rendered services and lawful actual expenses not already covered by paid fees are settled without double counting. No fees for unperformed future services or penalty merely for withdrawing are charged.
19.3. The Contractor may withdraw on its own initiative upon at least 30 calendar days’ notice and full compensation of the Customer’s losses under Article 780(2) of the Armenian Civil Code. Notice and the liability cap do not replace this obligation. Mandatory professional rules on ending representation and preventing harm remain applicable.
19.4. Material arrears under clause 12.2, failure to supply necessary data for more than 20 Business Days after a proper request, or another material breach may justify termination as permitted by law after a demand allowing at least 5 Business Days to cure. An unlawful instruction or mandatory prohibition permits immediate termination of the affected service. The 30-day period does not apply in these cases, but grounds and consequences remain governed by law, without excluding responsibility for the terminating Party’s own breaches.
19.5. Within 10 Business Days after termination, the Contractor provides a final calculation and refunds unused advance payments less sums lawfully payable. For evenly provided monthly services, the rendered portion is apportioned by calendar days of service unless another objective allocation was agreed in the Invoice. Issuing an invoice alone does not establish an expense. An undisputed refund is not withheld because the balance is disputed. The special Consumer deadline is in clause 19.8.
19.6. Within 10 Business Days after termination, originals, Customer documents and accounting data, existing deliverables, standard exports and pending-task information are handed over against a list to the Customer or its designated replacement provider, regardless of debt. Materials needed for an imminent mandatory deadline are supplied promptly. Standard handover is included; specialized migration requires separate agreement. Authority and access are ended after agreed handover as required by law; the Contractor’s own accounts and licences are not transferred.
19.7. For a distance or off-premises contract, a Consumer may withdraw without giving a reason within 14 calendar days of conclusion, subject to statutory exceptions. For services, the exception applies only after full and proper performance begun with the Consumer’s prior consent and prior information that this right will be lost after full performance. Starting work alone does not end the right. An early-start request and acknowledgment are recorded separately under clause 25.2.
19.8. Such withdrawal requires only an unambiguous statement sent before the deadline to info@onebusiness.am or another lawful channel; no special form is mandatory. The Contractor acknowledges electronic withdrawal on a durable medium and refunds the refundable amount within 14 calendar days after learning of the withdrawal, using the original payment method unless another lawful method is agreed. Only the value of services actually received may be deducted, and only as permitted by law. If the withdrawal right was not properly explained, Article 24.5 of the Armenian Consumer Protection Law extends the period, including up to 12 months after the original deadline; information provided during that period triggers the statutory 14-day period.
19.9. Consumer remedies for defects, delay and other breaches survive expiry of the 14-day period. A new Offer version does not amend an existing Agreement without separate agreement and has no retroactive effect.

20. Force majeure
20.1. Liability for non-performance is excluded to the extent the affected Party proves that extraordinary and unavoidable circumstances made performance impossible. War, natural disaster, mandatory prohibition, major infrastructure failure or cyberattack must satisfy those criteria and are not automatically force majeure. Lack of funds, ordinary technical faults and counterparty breaches alone do not qualify.
20.2. The affected Party promptly notifies the other, where possible within 5 Business Days, explains the effects, reasonably mitigates harm and supplies available evidence. Unjustified delay in notice entails liability for resulting additional loss. Statutory deadlines are not extended by agreement.
20.3. If an impediment continues for more than 60 calendar days, either Party may terminate the affected services by written notice, settling actual performance and refunding unused advances. Mandatory earlier termination rights remain available.

21. Claims and disputes
21.1. Claims are sent under section 15, identifying circumstances and requested remedies. A response is provided within 10 Business Days unless law requires a shorter period. The Parties seek in good faith to resolve disputes through negotiations.
21.2. Correspondence and negotiations do not restrict access to courts, competent authorities or interim relief and do not alter limitation or procedural periods. Mandatory mediation or another procedure applies only where required by law.

22. Governing law
22.1. Armenian law governs. Disputes are heard by the competent court under applicable jurisdiction and venue rules. The Offer does not deprive Consumers of a statutory choice of court or other mandatory protection afforded by applicable law.

23. Final provisions
23.1. Priority is given to mandatory law, expressly agreed individual written terms, the Invoice as to agreed price, scope and timing, the Offer, and correspondence clarifying performance, in that order. Unconfirmed oral assurances by unauthorized persons do not resolve inconsistencies. Partial invalidity does not invalidate the remaining terms if the Agreement can operate without the invalid part.
23.2. The Offer is issued in Russian, Armenian and English with identical numbering. In case of inconsistency, the Armenian text prevails unless the Parties expressly agree otherwise in a lawful form. This does not relieve the Contractor of providing complete and understandable information before acceptance.
23.3. Neither Party may induce persons involved in the services to breach existing confidentiality duties or unlawfully use the other Party’s materials. This does not prohibit lawful employment, general recruitment advertising or freedom to choose work. This Offer imposes no automatic recruitment penalty.

24.2. Registered address: [insert the address recorded in the state register]. Business and correspondence address, if different: [insert or confirm it is the same].

25. Invoice and Consumer wording
25.1. Wording for the Invoice: “Payment of this Invoice after receipt of the Offer constitutes acceptance of the OneBusiness Public Offer dated 18 September 2026 and the individual terms of this Invoice, including agreed scope, price, period and deadlines, communication, acceptance, liability and termination rules. The full stated version is attached to the Invoice message in a retainable file. Payment for a further period of an existing Agreement preserves the previously accepted version unless an amendment is separately agreed. Mandatory Consumer rights are preserved.” The version date must match the version actually provided and applicable.
25.2. Separate voluntary Consumer early-start statement: “Please begin the services under Invoice [number] dated [date] before expiry of 14 calendar days from conclusion of the Agreement. I have been informed that, after full and proper performance with my consent, I lose the right to withdraw without reason within that 14-day period, while retaining remedies for defects and other breaches. If I withdraw before full performance, only services actually received are payable to the extent permitted by law.” Record this as a separate confirmation with the Consumer’s name and date; no statement means no consent.
25.3. Example withdrawal notice: “To ‘BUSINESS TECH’ LLC, info@onebusiness.am. I, [name], give notice of withdrawal from the service agreement under Invoice [number] dated [date]. Agreement conclusion date: [date]. Reply contact: [contact]. Date sent: [date].” A signature is added for paper notices. This is an example, not a restriction on other unambiguous statements.
