Payment terms are the cheapest lever you have to control cash flow, and most freelancers never adjust them. They default to Net-30 because every template they've ever seen used Net-30 — and they wonder six months later why their runway looks the way it does.
The two most common terms are 'Net-30' and 'Due on Receipt.' The decision between them is rarely about which is better. It's about which fits the specific client, project size, and risk profile.
What the terms actually mean
Net-30 means payment is due 30 days after the invoice date. The clock starts when you send the invoice, not when the client receives or processes it. Some businesses interpret Net-30 as 30 days after their accounting cycle closes — be explicit if that matters to you. Variants you'll see: Net-15, Net-45, Net-60, Net-90. The longer the window, the more credit you're extending to the client at zero interest.
Due on Receipt means payment is due when the invoice arrives. In practice, this typically means within 3 to 7 business days, depending on the client's payment processing.
There are others worth knowing:
- 2/10 Net-30 — pay within 10 days for a 2% discount; otherwise pay full within 30.
- CIA (Cash in Advance) — 100% upfront, common for first-time clients or small jobs.
- 50/50 — half upfront, half on completion. The default for project work that takes more than two weeks.
When Net-30 is the right call
Net-30 is the standard for B2B work in most established industries. It's not generous — it's expected. Use it when:
- The client is an established business with formal AP processes. Their accounting team is set up for 30-day cycles and will resent shorter terms.
- The invoice value is large enough that the client needs internal approval. Even a $5K invoice often needs sign-off from someone who isn't the person you worked with.
- You have buffer cash and can absorb a 30-day wait without stress. Net-30 only works if you don't need the money in 7 days.
A useful rule: if pushing for shorter terms risks losing the client, Net-30 is the price of doing business with them.
When Due on Receipt is the right call
Due on Receipt is right when speed matters more than diplomacy. Use it when:
- The client is a small business or individual. There's no AP process to wait on — your contact can pay you the same day.
- The work is complete and the deliverable has been handed over. The leverage is at its peak the moment they have what they paid for.
- The invoice value is small enough that internal approval isn't required. Below a few thousand dollars, most clients can pay from a corporate card without escalation.
Due on Receipt also signals confidence. It implies you don't expect to chase. Some clients respect that; others find it aggressive. Know your audience.
The cash flow math
Run this calculation for your own business. Take your average invoice value, the number of invoices per month, and the average days from invoice to payment. Working capital tied up in receivables is roughly (value × count × days) / 30. Shifting average payment time from 35 to 15 days nearly doubles your effective monthly cash position. For a freelancer doing $10K/month, that's the difference between $11K and $5K parked in unpaid invoices.
The point isn't that Due on Receipt is universally better. It's that the default of Net-30 is a choice you're making, and you should make it deliberately.
The hybrid approach
The terms that actually work in practice are rarely textbook. A few patterns worth stealing:
- 50/50 with Net-15 on the back half. Half upfront protects you from non-payment. Net-15 on the back end accelerates closeout without scaring the client with 'Due on Receipt.'
- Retainer with Net-15. Monthly retainers should pay in 15, not 30. The work is ongoing; the cash flow should be too.
- Net-30 with a 2% discount for payment in 10 days. Some clients will take the discount and accelerate. The ones who don't pay you Net-30 anyway. You lose 2% on the fast payers but gain predictability.
How to phrase it on the invoice
Be unambiguous:
- 'Payment terms: Net-30. Due by May 15, 2026.'
- 'Payment terms: Due on receipt. Please remit within 7 business days.'
- 'Payment terms: 50% due on signing, 50% due on delivery.'
Avoid jargon-only versions. 'Net-30' alone is fine for sophisticated clients but baffling to first-time buyers. The calendar date removes ambiguity for everyone.
Pick the terms before you send the proposal
Payment terms should be negotiated when the project is, not when the invoice goes out. Putting Net-30 on your invoice for the first time, after the work is done, is when the client says 'we pay Net-60' and you have no leverage to push back.
In the proposal, before signing, write the terms plainly. Get agreement. Then the invoice is just confirming what's already settled.
