Freelancer Invoice Due Dates: Net 30, Net 15, and Getting Paid on Time
Write payment terms clients respect, set iPhone reminders before cash gaps, and track overdue invoices without a full accounting stack.
Clients say “we’ll pay you”—invoices say when. Net 30 is not “sometime next month”; it is a clock that starts on a defined trigger. Freelancers who nail terms and reminders stress less about rent than those who chase politely forever.
Define the trigger date
Payment terms need a start event:
- Invoice date (you send today → due in 30 days)
- Receipt date (client acknowledges → due in 30 days)
- Project milestone (approval email → due in 15 days)
Put the exact sentence on every invoice PDF and email body.
Net 30 vs Net 15 vs due on receipt
| Term | Best for |
|---|---|
| Due on receipt | Small jobs, new clients, retainers |
| Net 15 | Established clients, steady cash need |
| Net 30 | Enterprise, agencies, public sector |
| 50% deposit + Net 15 on delivery | Custom work, scope creep risk |
Shorter terms are not rude—they are cash-flow hygiene.
Late fees and pause clauses
State calmly:
- Late fee percentage after due date (check local law)
- Work pauses on new requests after X days overdue
- Right to charge collection costs if specified
You may never enforce them; they align expectations.
Reminder schedule on iPhone
For each open invoice:
- Day 0: sent
- Day 7: friendly “received?” if large amount
- Day 25 (Net 30): payment arriving soon reminder
- Day 31: overdue follow-up with invoice reattached
Bill reminders and calendar alerts beat memory when you juggle five clients.
Separate business bills from client cash
When payment lands, mentally split:
- Taxes set aside
- Business expenses due this month
- Personal transfer only after obligations funded
Pair with an irregular income bill calendar so client delays do not bounce utilities.
Partial payments and scope changes
Log amendments in the same note as the invoice:
- “50% paid 10/1—balance Net 15”
- “Added revision round 2—new line item invoiced 10/5”
Threads scatter; one timeline wins disputes.
International clients and FX
Note currency on the invoice. If conversion matters, record amount received in bank currency when paid—simplifies tax season.
When to escalate
After two professional reminders and 14+ days overdue:
- Pause deliverables per contract
- Ask accounts payable directly (not only your day-to-day contact)
- Consider small-claims or collections only above thresholds worth your time
