Write payment reminders people can respond to

Check whether the customer can act

Before sending another reminder, inspect whether the invoice reached the right person, includes required references and matches the agreed work. A customer cannot approve an invoice that is missing essential details.

ICAEW’s debtor guidance supports checking invoice completeness and following a collection process. A better message begins with that preparation. It does not assume the recipient is deliberately avoiding payment.

If the amount is disputed, state the disputed item and who is resolving it. Repeating an overdue notice while ignoring an open question can make the conversation less productive.

Use the message that fits the state

Keep templates short and editable. They should prompt the sender to check relevant facts, not conceal uncertainty behind polished language.

An illustrative reminder that uncovers a blocker

A supplier sends a general reminder three times without an answer. A reviewed message to the customer’s accounts contact identifies the invoice and asks whether approval information is complete. The contact replies that the delivery acceptance document is missing.

The supplier sends the document, records the handoff and agrees the next check. Track whether the information reached the right person and what still blocks payment. Check remaining disputes or payment constraints at the agreed follow-up.

Keep that explanation in the record. If many invoices lack the same attachment, fix that handoff. Increasingly persuasive reminder wording will not supply the missing document.

Plan the channel and permission

Use the agreed business contact route and follow applicable rules. For WhatsApp, the Business Messaging Policy includes permission and opt-out expectations. Check the current policy and distinguish service communication from unrelated marketing.

A customer who asks for invoice updates by email may not welcome repeated calls to a personal number. Keep contact preferences and escalation rules understandable to the staff doing follow-up.

Avoid inventing legal consequences or automated threats. Sensitive or disputed collections need the people authorized to decide how the business proceeds.

1. Check the current balance, due date and supporting documents.
2. Review the latest customer response and any dispute.
3. Choose the appropriate contact and channel.
4. Send a concise message asking for a specific action or status.
5. Record the response and schedule the next check.
6. Escalate under the business’s approved process when needed.

Use assistance without losing accountability

An internal reminder can help a colleague remember to review an invoice. That is different from a system automatically contacting the customer. Make both actions explicit in the workflow so staff know what actually happened.

Before sending a reminder, compare the message with the current invoice, any dispute and the latest payment check. Name the action the customer can take: provide a missing reference, confirm a date or explain a disagreement. After sending, record the response and next check.

This keeps reminders accurate when different colleagues cover the same account.

Measure resolved blockers, verified receipts and the effort spent following up. Read rates and message counts alone cannot tell you whether the collection process improved.
