Terms of Service

The RoiMaxx System is operated by SELLNITY CO., LTD ("Sellnity", "we", "Party B"), providing an all-in-one online advertising account & infrastructure management solution on Meta for business customers ("customer", "Party A") under a Service Contract (Framework Contract) signed between the two parties.

These Terms of Service implement the Service Contract, in accordance with Vietnam's Civil Code No. 91/2015/QH13, Commercial Law No. 36/2005/QH11, Advertising Law No. 16/2012/QH13, Cybersecurity Law No. 24/2018/QH14, and related amending and implementing regulations.

By creating an account, signing the Service Contract/an Order, or using any RoiMaxx service, the customer confirms that it has read, understood, and agrees to be bound by these Terms of Service, the signed Service Contract, and the accompanying Privacy Policy.

• Service Contract (Framework Contract): the framework agreement between Sellnity and the customer, effective until either party gives written notice of termination.
• Order (PO): the document confirming each budget top-up/service renewal, specifying scope, budget, and payment value.
• Acceptance Record: the document confirming the actual service/budget used per Order, forming the basis for settlement and invoicing.
• Deposit: the 50 USD payment made by the customer to activate its account on the RoiMaxx System; this is not a service fee.
• Ad account: a Meta Ads advertising account (personal/BM/Invoice) provisioned by Sellnity for customer use.
• BM (Business Manager): a Meta business account used to manage advertising assets.
• VIA: a Facebook personal account used to administer or operate an ad account or BM.
• RoiMaxx Wallet: an internal balance used to fund payments, service fees, and account activation funds.
• Activation fund: money deposited by a customer to activate, maintain, or fund an ad account.
• Remaining budget: the unused advertising budget of an ad account that has been locked/restricted, recovered by Sellnity from Meta and handled per section 11.

Sellnity provides the following bundled service groups:

• Ad account infrastructure & resource management: provisioning, distributing, and centrally managing ad accounts (personal/BM/Invoice); status monitoring, incident alerts, and technical support to redirect budgets when an account is locked/restricted.
• Cash flow & budget management: a centralized Wallet for funding/allocating budget; real-time balance and spend-rate tracking, and full transaction history for reconciliation.
• Reporting, review & API integration: automatic sync of spend/performance data via the Meta Platform API; periodic reports and advertising-policy compliance tools.
• System administration & operations: multi-level access control (Admin/Staff/Customer), auditable activity logs, order processing, and direct support/alert channels.
• Customer support & care: a dedicated Account Manager (AM) as the point of contact for top-up/refund/budget-transfer requests, technical support, data reconciliation, and policy-risk alerts.
• The scope, timeline, budget, and price of each deployment are defined in the corresponding Order and need not be specified in detail in these Terms.

The customer must provide accurate registration information and protect the login credentials of its own account and of personnel it authorizes (Admin, Accountant, Staff...) on the RoiMaxx System. Sellnity is not responsible for losses caused by the customer disclosing credentials to a third party.

Each account may only be used by personnel the customer has authorized. Sharing or transferring an account to a third party without Sellnity's written approval is a breach of these Terms.

To verify the actual user's identity and ensure budget-management accountability, the customer pays an initial deposit of 50 USD to activate its account on the RoiMaxx System. This is not a service fee and is refunded in one of two ways:

• Credited to the budget wallet: once cumulative spend across the customer's account portfolio reaches 5,000 USD, the deposit automatically converts into advertising budget; Sellnity issues a 50 USD VAT invoice and credits the net amount to the Budget Wallet.
• Refund at contract settlement: if cumulative spend at the time of termination reaches at least 5,000 USD, Sellnity refunds the full 50 USD. If it does not reach 5,000 USD, Sellnity deducts a 10 USD management fee (VAT included) and refunds the remainder, within 03–15 business days of the parties signing the cooperation-termination confirmation and completing related financial obligations.
• The deposit is converted to VND using the exchange rate defined in section 7 at the time the two parties settle the deposit. The deposit policy may be adjusted monthly and will be communicated in writing.

Whenever the customer needs to top up budget or renew a service package, the two parties issue a corresponding Order. The service cost for each round comprises: direct advertising budget and an account/infrastructure management fee (a fixed percentage of budget or an agreed package, specified in each Order) — the service fee excludes VAT.

Services are provided on a prepaid basis: Sellnity activates, tops up budget, and records the management fee on the RoiMaxx System only after the customer has paid the Order in full.

The customer must pay 100% of the Order value (VAT included) within 01 business day of the two parties confirming and signing that Order.

Advertising budget registered on the system is not refundable in cash or by bank transfer under any circumstances, except where the Contract is terminated due to Sellnity's fault or a force-majeure event under section 12.

Sellnity issues a lawful VAT invoice matching the amount actually received for each Order. Each budget round is settled via an Acceptance Record once the customer has spent 100% of the topped-up budget, or based on actual spend if the parties stop mid-way. The Acceptance Record is deemed legally valid if the customer does not raise a complaint or sign it within 05 business days of receipt.

Service value, invoices, and all payment obligations are denominated and settled in Vietnamese Dong (VND). Because Meta advertising infrastructure costs are recorded in USD, the parties use the USD amount on the Order as a reference, converted at the transfer-sell rate published by Vietnam Technological and Commercial Joint Stock Bank (Techcombank) at the time the Order is finalized.

The exchange rate on an Order is valid for payment for 24 hours from when Sellnity sends the Order. If the Techcombank rate rises more than 0.5% above the rate on the Order once this window has passed, Sellnity may cancel the original Order and issue a new one at the current rate. If the movement is within 0.5%, the parties proceed at the original VND value.

The customer may use the advertising accounts provided by Sellnity to run ads stably and long-term as agreed; it has full control over the content, format, scope, and timing of advertising, and bears full legal responsibility for the accuracy, brand/IP rights, and any required advertising licenses (for conditional goods/services) of content, images, and video used.

The customer may request prompt technical support, transaction review, and service-quality complaints from Sellnity, and has the right to unilaterally terminate the Contract and claim damages if Sellnity breaches the Contract or a dispute arises over an account it provided.

The customer must pay for services on time; use accounts for lawful purposes consistent with Meta's advertising policies; keep its accounts secure and not share login credentials with unauthorized parties; and must not use Sellnity's infrastructure to run any of the absolutely prohibited categories listed in section 10.

Sellnity may receive payment as agreed, monitor account usage to help keep the customer's advertising activity stable, claim damages if the customer breaches the Contract, and reclaim accounts once the Contract expires.

Sellnity must hand over advertising accounts with full information and conditions for the customer to advertise within 01 day of the Contract taking effect; make its best technical effort to keep accounts stable, and resolve appeals or transfer budgets as soon as possible when an account is disrupted by Meta policy.

Sellnity must not access, interfere with, modify, or use an account while it is assigned to the customer, except for the technical interventions described in section 3 (detecting a policy/legal violation, or handling incidents/appeals/budget redirection at the customer's request).

Where an account-related dispute causes loss to the customer, Sellnity is responsible for resolving it and compensating the actual damage incurred, capped at the total service fee Sellnity received for the corresponding Order. Sellnity keeps the customer's account information and data confidential and will not use the customer's advertising data, customer information, or marketing strategy for any third party or personal purpose — violations are subject to penalties and damages.

The customer must not perform any of the following when using Sellnity's services:

• Run advertising that violates Meta's Advertising Policies (prohibited products, fraudulent or misleading content).
• Use Sellnity's resources to run any absolutely prohibited category, including: counterfeit/imitation brands, gambling/betting, finance or supplements that violate Meta policy, counterfeit goods, traditional medicine, scams, or accounts of unclear origin ("dirty" accounts).
• Use an account for financial fraud, money laundering, or other unlawful activity.
• Intentionally exploit system vulnerabilities or unlawfully interfere with Sellnity's technical infrastructure.
• Share, resell, or re-lease a provided account to a third party without Sellnity's approval.
• Provide false information during registration, identity verification, or business-license verification.

If an advertising account is locked or restricted by Meta, Sellnity accepts the incident report during business hours (or via automated/Telegram support channels); reissuing an account or transferring budget is expected to take 24–72 business hours depending on Meta's response, and Sellnity will recover the account's Remaining Budget as soon as possible.

Based on the Remaining Budget recovered, Sellnity reviews the account's activity history and advertising content to determine the cause: if the customer is at fault (content/format violating policy or law), Sellnity may deduct the portion corresponding to actual incident-handling/appeal costs or the extent of damage, refunding the remainder. If the cause is not the customer's fault (Meta policy, a platform technical fault, or Sellnity's own fault), Sellnity refunds 100% of the Remaining Budget with no deduction.

Sellnity will notify the customer in writing (email or on the RoiMaxx System) of the Remaining Budget amount, the conclusion on cause, any deduction applied with its basis, and the amount actually refunded.

All refunds under this section are credited directly to the customer's advertising budget Wallet on the RoiMaxx System for continued use, not paid in cash/by transfer — except where the parties agree to terminate the Contract, or Sellnity cannot provide a replacement account within 30 days, in which case Sellnity refunds by bank transfer within 15 business days along with an Acceptance Record based on actual spend.

If the customer disagrees with the conclusion on cause or the deduction applied, the parties reconcile using actual spend data and activity history on Sellnity's System to agree on final figures, in the spirit of negotiation set out in section 14.

The Contract terminates when: the parties agree in writing; the term expires without renewal; or a party breaches a fundamental obligation and fails to remedy it within 07 business days of receiving the other party's written notice.

If the customer terminates the Contract early, it must pay in full for services and financial obligations incurred up to the termination date, as agreed by both parties. If Sellnity's breach leads to termination, the customer may demand a refund of amounts paid for services not yet performed and may unilaterally terminate the Contract; termination does not affect the right to claim damages for breaches arising before or at termination.

A large-scale Meta-side system incident (mass account sweeps, a global API outage, or a sudden policy change disrupting infrastructure for more than 07 days) is treated as a Technical Force Majeure Event — Sellnity is not liable for schedule-related damages, and the parties will cooperate to reallocate budget or pause the Order. If such an event lasts more than 14 days, the customer may terminate the Contract and demand a refund of unused budget.

Sellnity acts as a provider of lawful usage rights over advertising account resources; it is not responsible for business performance, campaign results, or Meta decisions to lock or restrict accounts that fall outside its reasonable control. Sellnity warrants that an account is lawfully managed and functioning normally at the time access is granted, but does not warrant that an account will never be locked/restricted for reasons outside its control on Meta's side.

In all cases, Sellnity's maximum liability for an incident will not exceed the total service fee Sellnity received for the Order directly related to that incident.

The parties will proactively keep each other informed of contract progress; if an adverse issue arises, both sides will promptly notify each other and negotiate in good faith for mutual benefit (recorded in minutes). If no agreement is reached, either party may bring the dispute to a competent court under the laws of Vietnam.

The parties are released from liability in force-majeure events as provided by law.

Sellnity may update or amend these Terms from time to time to reflect changes to the Service Contract, our operations, legal requirements, or Meta policies. The latest version will be published on this page with its effective date; material changes will be notified by email or on the RoiMaxx System. Continuing to use the services after an update means the customer accepts those changes.
