Terms of Service

Simple Invoicing · Last updated August 29, 2026

These Terms of Service (“Terms”) govern access to and use of the Simple Invoicing service (“Service”) at simpleinvoice.dev, including the admin application, customer invoice pages, and related features. By using the Service, you agree to these Terms.

1. The Service

Simple Invoicing is a software platform that helps businesses create and send invoices, collect payments through integrated processors, manage contacts, and configure recurring billing. Each account holder receives a separate workspace. You are responsible for the accuracy of information you enter and for how you use the Service in your business.

2. Eligibility and accounts

  • You must be at least 18 years old and able to form a binding contract to use the Service as an account holder.
  • You are responsible for maintaining the confidentiality of your sign-in credentials and for activity under your account.
  • You must provide accurate account and business information and keep it up to date.
  • You may sign in with a username and password or, where enabled, with Google Sign-In.

3. Acceptable use

You agree not to:

  • Use the Service for unlawful, fraudulent, or deceptive purposes.
  • Send invoices or collect payments for goods or services you are not authorized to sell.
  • Upload malware, attempt unauthorized access, or interfere with the Service or its users.
  • Reverse engineer, scrape, or resell the Service except as expressly permitted.
  • Violate applicable tax, consumer protection, payment network, or email laws.

Account holders are solely responsible for invoices they issue, payment terms they set, taxes they owe, and communications they send to their customers.

4. Customer invoice pages

Customers who receive an invoice link may view, print, and pay an invoice you issue. Payment is voluntary unless otherwise required by your agreement with that customer. Customer pages are provided on your behalf as the account holder; your relationship with your customers is between you and them, not between them and the Service operator.

5. Third-party services

The Service may integrate with third parties such as Google (sign-in and optional Gmail delivery) and Square (payment processing). Your use of those features is also subject to the applicable third-party terms and policies. We are not responsible for third-party outages, decisions, fees, or actions.

6. Fees and payments

Payment processing fees, chargebacks, refunds, and settlement timing are handled by your payment processor according to its agreements. You are responsible for configuring your payment settings correctly and for resolving disputes with your customers.

7. Intellectual property

The Service, including its software, design, and branding, is owned by the Service operator or its licensors. You retain ownership of content you upload or create, including business details, logos, and invoice data. You grant us a limited license to host, process, and display that content only as needed to operate the Service.

8. Privacy

Our collection and use of personal information is described in the Privacy Policy, which is incorporated into these Terms by reference.

9. Availability and changes

We strive to keep the Service available and secure, but we do not guarantee uninterrupted or error-free operation. We may modify, suspend, or discontinue features with reasonable notice where practicable. We may update these Terms from time to time by posting a revised version with a new “Last updated” date. Continued use after changes become effective constitutes acceptance of the revised Terms.

10. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE FULLEST EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS OR THAT INVOICES, PAYMENTS, OR EMAILS WILL ALWAYS BE DELIVERED WITHOUT ERROR.

11. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, THE SERVICE OPERATOR WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF ONE HUNDRED U.S. DOLLARS (USD $100) OR THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE CLAIM, IF ANY.

12. Indemnification

You agree to defend, indemnify, and hold harmless the Service operator from claims, damages, losses, and expenses (including reasonable legal fees) arising from your use of the Service, your invoices or business practices, your breach of these Terms, or your violation of law or third-party rights.

13. Termination

You may stop using the Service at any time. We may suspend or terminate access if you violate these Terms, create risk for other users or the Service, or as required by law. Upon termination, your right to use the Service ends, but sections that by nature should survive will continue to apply.

14. Governing law

These Terms are governed by the laws of the United States and the State of Delaware, without regard to conflict-of-law rules, except where mandatory local law applies.

15. Contact

Questions about these Terms may be directed to the administrator of simpleinvoice.dev.
