A four-touch operating template
| Timing | Purpose | Example message |
|---|---|---|
| Before the due date | Make payment easy | “Hi [Name] — invoice [ID] for [amount] is due [date]. You can use [approved methods]. Let me know if you need it resent.” |
| On the due date | Confirm delivery | “Invoice [ID] is due today. Please confirm it reached the right person. Reply if any line needs clarification.” |
| After a missed date | Find a process issue | “Our records show [amount] open for invoice [ID], due [date]. Is it in your payment queue, or should we resolve a question?” |
| After a promised date passes | Reconfirm timing | “You mentioned payment on [date]. We have not matched it to the account. Could you confirm a new expected date or send remittance details?” |
Set actual intervals using your agreement, client workflow, and payment history. Keep wording factual and courteous. Avoid threats, invented late fees, and claims about legal rights. If a dispute arises, pause the routine sequence and preserve the client's explanation and supporting records.
Make a tracker the source of truth
For every invoice, record ID, amount open, due date, last message, channel, client response, promised date, and next-action owner. Reconcile cleared deposits before marking it paid. Stripe's invoicing guidance describes configurable reminders before, on, or after a due date; the process can also live in a spreadsheet or billing system.
At weekly review, sort by next contact date and oldest due date. If the owner is away, a colleague should be able to see what the client has already been told.
Separate process delays from payment risk
If an invoice went to the wrong inbox, resend and update the contact. If a purchase-order issue exists, record its owner. If the client disputes scope, preserve the dispute and agreement instead of sending automated “pay now” messages as if nothing changed.
A reminder is not a collection remedy. Escalation, interest, service pauses, and legal steps depend on contracts and applicable rules. Get qualified advice before acting on a contested account.
Learn from your own cases
Record invoice age at first contact, response date, cleared-payment date, and resolution type. After you have enough real cases, compare periods using your own data. This draft has no observed sample and claims no average number of days saved.
