1. Set up the customer before the work starts
Collections starts at the quote. Before you begin work for a new customer, agree and record:
- The payment terms, in writing, and the due date they produce. Our guide to Net 30 payment terms covers how to word them.
- Who receives invoices, and their email address. This is often an accounts payable mailbox, not the person who hired you.
- Whether the customer needs a PO number, a supplier number or a particular invoice format.
- For larger accounts, enough about the business to decide how much credit to give. A credit application form collects it in one go.
Most of the blockers that delay payment later, such as a missing PO or the wrong contact, are cheaper to fix here than after the due date.
2. Invoice correctly and on time
Send the invoice as soon as the work or milestone is done, to the right address, with the PO, the agreed terms and the actual due date on it. An invoice sent two weeks late starts its payment clock two weeks late. Our guide to invoice terms and conditions has a terms block you can copy.
3. Confirm the invoice arrived
For larger invoices or new customers, check within a few days that the invoice reached the right person and nothing is missing. One short email catches problems while there is time to fix them.
4. Remind and follow up on a fixed schedule
Decide the schedule once and apply it to every customer: a reminder shortly before the due date, a follow-up the day after, then follow-ups at set intervals, each one asking for something specific. The collections email sequence sets out a full schedule with wording for each step.
5. Work the replies
This is where most of the effort goes, and where most processes fall apart. Every reply needs the right next action:
| Customer says |
Next action |
Who acts |
| "We'll pay on the 30th" |
Record the date, follow up on the 31st if unpaid |
Collections owner |
| "We need a PO" |
Get the PO, reissue the invoice, restart the clock |
Collections owner, with the account manager |
| "Send it to accounts payable" |
Update the contact, resend, confirm receipt |
Collections owner |
| "This isn't right" |
Pause chasing, resolve the query |
Account manager or owner |
| "We can't pay it all now" |
Agree a written plan, or decline |
Owner |
| No reply |
Try another contact at the customer |
Collections owner |
A dispute should stop the normal reminders until it is resolved. Our guide to invoice disputes covers how to handle one, and the payment plan agreement guide has a template for when the customer needs time.
6. Escalate by rule, not by mood
Decide in advance what triggers an escalation, so it does not depend on anyone's mood that day. For example: escalate to the business owner when a customer misses two promised dates, or an invoice passes 45 days overdue. Escalation might mean a firmer letter, contact with someone more senior at the customer, or pausing further work.
7. Close out every invoice
An invoice leaves the process in one of four ways: paid in full, settled under an agreed plan, credited because the customer was right, or written off. Apply payments and credits promptly so the aging report stays true. For invoices that will not be paid, decide on purpose: pass the debt to an outside party, or write it off. Our resource pages on bad debt expense and the allowance for doubtful accounts explain how that is recorded.
