InvoiceLynx Service Agreement

Effective Date: November 11, 2026  ·  Last Updated: November 11, 2026

This InvoiceLynx Service Agreement (the "Agreement") governs your use of InvoiceLynx, a hosted service from Chain Interlynx, LLC ("ChainInterLynx," "we," "us," or "our") that lets a business accept online payments of its QuickBooks Online invoices through its own Stripe account and records those payments in QuickBooks Online (the "Service"). This Agreement supplements our Terms of Service. By connecting a QuickBooks Online company or a Stripe account to the Service, or by otherwise using it, you agree to this Agreement on behalf of that business ("you" or "your"). Your customers who pay invoices through the Service are referred to as "Payers."

1. The Service

The Service (a) reads the open invoices in the QuickBooks Online company you connect; (b) delivers invoices and payment links to your Payers by email and through a hosted payment page; (c) processes Payer payments by card or bank account (ACH) through your Stripe account; and (d) records each successful payment in QuickBooks Online as a payment applied to the related invoices. During setup, the Service creates a "Stripe Clearing" account and a "Stripe" payment method in your QuickBooks Online company if they do not already exist. The Service does not edit or delete any existing QuickBooks Online record.

2. Your Stripe Account

  1. Merchant of record. Payments are processed by Stripe, Inc. and its affiliates ("Stripe") on your own Stripe account, which you connect through Stripe Connect. You are the merchant of record for every payment. Payment processing is subject to the Stripe Services Agreement and the Stripe Connected Account Agreement, which form an agreement between you and Stripe.
  2. Funds. Payer funds settle to your Stripe account and are paid out by Stripe on Stripe's schedule. ChainInterLynx does not hold, receive, or control your funds, other than the fees described in Section 3, which are deducted at the time of each payment.
  3. Refunds, disputes and returns. You are solely responsible for refunds, chargebacks, disputes, returned or failed bank payments, and any related fees, reserves, or holds imposed by Stripe or a payment network.

3. Fees

  1. Plans. The Service is offered under the plans described in the Service at the time you select them, which may include a pay-as-you-go plan without a monthly charge and subscription plans with a monthly charge (each, a "Plan"). The fees, inclusions, and limits of each Plan are shown in the Service and form part of this Agreement.
  2. Platform fees. Where your Plan includes a per-payment fee, that fee is calculated as shown in the Service and is deducted from each payment by Stripe at the time of the transaction as an application fee payable to ChainInterLynx.
  3. Payer convenience fee. Where your Plan includes it, Payers who choose to pay online are charged a flat online payment convenience fee, which is disclosed to the Payer before payment, appears as a separate line item, and is retained by ChainInterLynx. The convenience fee is charged for the convenience of paying online and is not a charge for the goods or services on your invoice. You agree to offer Payers at least one method of paying you without the convenience fee, such as check, and not to describe the fee as your own charge.
  4. Subscription fees. Subscription Plans are billed in advance through Stripe for each billing period, renew automatically, and may be cancelled at any time effective at the end of the current billing period, as described in the Terms of Service.
  5. Processing fees not included. ChainInterLynx fees do not include Stripe's processing fees. Stripe charges its fees to your Stripe account under your agreement with Stripe.
  6. Taxes. Fees exclude taxes, which are your responsibility unless we collect them.

4. Changes to Fees and Plans

  1. Ordinary changes. We may change our fees, fee structure, or Plans from time to time. We will give you at least thirty (30) days' notice by email or in the Service before any increase or structural change applies to you. A change to a subscription fee will take effect only at the start of your next billing period after the notice period ends, and never during a billing period for which you have already paid, whether monthly or annual.
  2. Required changes. If a change in law or regulation, an order or guidance of a governmental authority, a rule or requirement of a card network or the ACH network, or a requirement or policy of Stripe or another payment processor (each, a "Required Change") restricts or prohibits any part of our fee structure, including the Payer convenience fee, we may modify, suspend, or discontinue the affected fee and replace it with a fee of comparable amount payable by you, in the same manner as the platform fees described in Section 3.2. We will give you as much advance notice of a Required Change as is reasonably practicable and, where the Required Change permits, at least ten (10) days' notice. A Required Change may take effect immediately when compliance requires it.
  3. Your right to cancel. If you do not accept a change, you may stop using the Service or cancel your subscription before the change takes effect, without penalty.

5. Your Responsibilities

  1. Ensuring that your invoices, customer information, and email addresses in QuickBooks Online are accurate, and that you are entitled to collect every amount you request through the Service.
  2. Complying with all laws, regulations, and card network and ACH rules that apply to your business and your collection of payments, including any state laws governing convenience fees and surcharges.
  3. Responding to Payer inquiries, and handling refunds and disputes, in accordance with your own policies and the requirements of Stripe and the payment networks.
  4. Not using the Service for any business or transaction prohibited by Stripe's Restricted Businesses list or by applicable law.

6. Emails Sent on Your Behalf

You authorize us to send invoices, payment links, payment receipts, and one-time sign-in codes to your Payers on your behalf. These messages identify your business by name, are sent from a ChainInterLynx domain, and direct replies to the reply-to address you provide. They are transactional messages relating to your invoices; you will not use the Service to send marketing messages.

7. Recording Payments in QuickBooks Online

The Service records each successful payment in QuickBooks Online automatically. Bank payments are recorded when Stripe confirms they have cleared. If a payment later fails, is refunded, or is disputed, the Service will notify you and flag the payment for your review, and you are responsible for making any corresponding entries in QuickBooks Online. You remain responsible for reconciling your QuickBooks Online records with your Stripe account and your bank.

8. Your Data

When you connect a company, you authorize the Service to read the QuickBooks Online data needed to provide it (such as company information, customers, and invoices, including invoice PDFs) and to create the records described in Section 1. QuickBooks and Stripe credentials are stored encrypted. We use your data only to provide the Service, never sell it, and handle it as described in our Privacy Policy. You may disconnect QuickBooks Online or Stripe at any time from the Service's settings.

9. Suspension and Termination

You may stop using the Service at any time. We may suspend or terminate the Service as provided in the Terms of Service, or immediately if Stripe disables your account or we reasonably suspect fraud or a violation of law or payment network rules. On termination, payment links stop accepting payments. On request, we will delete your stored data within thirty (30) days, except records we must keep by law. Payments already recorded remain in your QuickBooks Online company.

10. Disclaimers and Limitation of Liability

The disclaimers and limitations of liability in the Terms of Service apply to the Service. Without limiting them, ChainInterLynx is not responsible for the acts or omissions of Stripe, Intuit, any bank, or any payment network; for funds held, reserved, or reversed by Stripe; for chargebacks, failed bank payments, or fraud by Payers; or for delays in recording payments caused by the unavailability of QuickBooks Online or Stripe.

11. Intuit and Stripe

QuickBooks and Intuit are trademarks of Intuit Inc. Stripe is a trademark of Stripe, Inc. The Service is an independent product of Chain Interlynx, LLC and is not affiliated with, endorsed by, or sponsored by Intuit Inc. or Stripe, Inc. Neither Intuit nor Stripe is a party to this Agreement.

12. Governing Law; Contact
