Use your contract, payment terms, client relationship, and local requirements to set the actual cadence. This guide is operational guidance, not legal advice.
Avoid vague subjects such as “Urgent” or “Payment” when a specific invoice number makes the message easier to identify and route.
| Field | Why it matters |
|---|---|
| Client and contact | Shows who receives and owns the response |
| Invoice number and amount | Prevents ambiguity |
| Due date and days overdue | Determines the follow-up stage |
| Last reminder date | Stops duplicate or excessive messages |
| Next follow-up date | Turns the process into a schedule instead of a memory task |
| Promise-to-pay date | Creates a specific checkpoint |
| Dispute or blocker | Routes the invoice away from generic reminders |
| Notes and attachments | Preserves the history |
Overdue Payments Agent is a lightweight Notion tracking system for invoice details, reminder stages, draft messages, next follow-up dates, promise-to-pay notes, and follow-up history. It does not replace accounting software or send messages automatically.
One-time $19 USD purchase. Notion is required; Custom Agent features require a Business or Enterprise plan and separately billed Notion credits.
Keep the message calm and factual. Include the invoice number, amount, original due date, payment link or instructions, and one clear request: confirmation, an expected payment date, or notice of any issue.
A common approach is to send a friendly reminder on the first business day after the due date, then follow a consistent schedule based on your contract, client relationship, and business policy.
Many businesses use a first reminder, a firmer second reminder, and a final notice before moving to a defined escalation step. The exact number should match the contract, amount, relationship, and applicable rules.
Avoid threats you are not prepared or permitted to carry out, emotional language, unclear amounts, missing invoice details, and invented late-fee or legal claims.
