# PAYBAACK. > PAYBAACK is a human-reviewed, AI-assisted accounts-receivable desk for overdue, undisputed B2B invoices. ## What PAYBAACK does - Starts with one authorized late B2B invoice; no ERP integration is required for the private beta. - Prepares and tracks polite, approved payment follow-ups. - Logs outreach, responses, payment promises, and next actions. - Escalates disputes, legal issues, missing facts, changed amounts, and requests to stop contact to the creditor. ## What PAYBAACK does not do - It is not a law firm, debt buyer, or consumer-debt collector. - It does not give legal advice, threaten debtors, invent facts, negotiate disputes autonomously, or process card/bank credentials. - It does not claim collection results until they are verified by the customer. ## Best fit US B2B service businesses with an overdue invoice that has a clear balance, named customer contact, payment path, and no active dispute. Initial focus: marketing and creative agencies with 5–30 employees. ## Private-beta intake Provide: creditor legal name, invoice number and balance, due date, debtor contact, payment link/instructions owned by the creditor, relevant documents, known context, and express authorization for contact. Do not provide bank credentials, card numbers, or sensitive personal information in an initial request. ## Pages - [Landing page](https://paybaack.com/): product overview and private-beta request. - [AP agent experiment](https://paybaack.com/ap.html): an early concept for accounts-payable teams to receive, route, and answer vendor invoices. It does not make payment decisions or change vendor payment details. - [Agent-readable status](https://paybaack.com/agent.json): capabilities and current limitations.
