How to invoice a client every month for the same service: what a recurring invoice must repeat and what must change, numbering, the day to send, handling price.
A recurring invoice bills the same client for the same service at a fixed interval: weekly lawn care, biweekly cleaning, monthly retainer, quarterly maintenance. The lines barely change; the invoice number, the service period and sometimes the quantity do. Done by hand it is five minutes a month per client, which at twenty clients is the reason people stop invoicing on time.
| Element | Recurring | Changes each cycle |
|---|---|---|
| Client, address, payment terms | Same | |
| Line descriptions and rates | Same | Only on an agreed price change |
| Invoice number | New number every cycle, same sequence as other invoices | |
| Service period | “Lawn care, March 2026” or “Weeks of Mar 2, 9, 16, 23” | |
| Quantities | Usually same | Skipped or extra visits |
| Due date | Same offset | Recomputed from the invoice date |
At about five recurring clients, manual duplication starts slipping a few days each month, and late invoices are paid late. An invoicing app with a recurring schedule sends the invoice on the day, numbers it, attaches the pay link and marks it paid when the money lands. The template on this page covers the manual version; the app covers the rest.

An invoice issued automatically or on a fixed schedule for the same service to the same client: weekly, biweekly, monthly or quarterly. Each one has a new number and service period; the lines and rates stay the same.
Bill on the 1st for the month ahead, one line: “Retainer, [service], April 2026”, with the agreed amount and Net 7 or due-on-receipt terms. Extra work beyond the retainer goes on separate lines or a separate invoice.
No. Every invoice needs a unique number from your normal sequence. The recurring nature is shown by the service period in the description, not by repeating a number.
Yes, and for retainers it is standard. For visit-based services most clients prefer billing after the month; either is fine as long as the agreement says which.
Confirm in writing, send no invoice or a zero invoice for that period, and restart with the next period. If the agreement has a minimum term or a skip fee, invoice that line instead.
