Terms of service

Last updated: [date]. These terms are a contract between you and [Your legal company name] ("we", "us"), operator of InvoiceFlow.

1. The service

InvoiceFlow lets you create invoices, send them by email as PDFs, and use an API to do the same. We may change or improve the service from time to time.

2. Your account

You must provide a valid email address, keep your password and API keys secret, and are responsible for activity under your account. You must be at least 18 or have legal capacity to enter contracts. Tell us promptly if you suspect unauthorised use.

3. Free trial

New accounts receive a 7-day free trial with the limits shown on our pricing page. We may limit one trial per person or business and may end trials that appear abusive.

4. Plans, limits and fair use

Each plan has limits on invoices sent, API keys and API requests, as published on our pricing page. Exceeding a limit may block further use until the limit resets or you upgrade. We may change plans and prices; changes to a plan you have already paid for apply from your next billing period.

5. Payments in cryptocurrency

We accept Bitcoin and USDT (TRC-20) only. Each payment shows an address, an exact amount and a time window.
You are responsible for sending the exact amount, on the correct network, to the correct address, within the window. Blockchain transactions are irreversible and we cannot recover funds sent to the wrong address or network.
Network fees are paid by you. Bitcoin amounts are based on an exchange rate at the time the payment is created.
Your plan starts when the payment is confirmed on the blockchain.
Payments that do not match automatically may be reviewed manually at our discretion. See our refund policy.

6. Acceptable use

You must not use InvoiceFlow to send spam, unsolicited bulk email, fraudulent, deceptive or illegal invoices, phishing, or content that infringes others' rights. Send invoices only to people you genuinely do business with. You must comply with applicable law, including tax and e-invoicing rules. We may suspend or terminate accounts that breach this section, with or without notice where necessary to protect others. Accounts that cause repeated bounces or spam complaints may be paused automatically until we have reviewed them.

7. Your content and data

You own the invoice data and documents you enter or upload. You grant us the right to store and process it, and to email it to the recipients you choose, to provide the service. You confirm you have the right to provide your clients' details. See the privacy policy.

8. API use

Use the API only with your own keys and within the published limits. Do not attempt to bypass rate limits, probe for vulnerabilities without permission, or resell access without our written consent.

9. Availability

We work to keep the service running but do not guarantee uninterrupted or error-free operation. Email delivery depends on third parties and recipients' mail systems and is not guaranteed.

10. Disclaimers and liability

The service is provided "as is". InvoiceFlow is not accounting, tax or legal advice. To the maximum extent permitted by law, we are not liable for indirect or consequential losses, and our total liability for any claim is limited to the amount you paid us in the 3 months before the claim arose.

11. Termination

You may stop using the service at any time. We may suspend or end your access if you breach these terms or if required by law. On termination you may export your invoices for a reasonable period on request.

12. E-signatures

The e-signature feature is a simple tool for collecting electronic signatures. You are responsible for the content of documents you send, for having the right to send them, and for deciding whether an electronic signature is legally suitable for that document in your jurisdiction. We do not provide legal advice and do not guarantee that a signature will be accepted by any court, authority or counterparty. Signers are shown an electronic-signing consent before they sign, and we record an audit trail (times, IP address, browser and a document fingerprint).

13. Bulk sending

You may bulk-send only to recipients you have a genuine business relationship with. You are responsible for the accuracy of the data you upload and for compliance with email, privacy and invoicing laws. Bulk sending counts against your plan limits and may be paused or limited to protect deliverability.

14. AI assistant

The AI assistant is provided for convenience and can produce incorrect or incomplete answers. Review anything it prepares before you confirm. It is not accounting, tax or legal advice. Your chat messages are processed by a third-party AI provider as described in our privacy policy.

15. Changes, law and contact

We may update these terms and will post the new date above. These terms are governed by the laws of [Your country], and courts there have jurisdiction, subject to any mandatory consumer rights. Questions: felicelse@gmx.com.
