Net-30 vs Net-15 vs Due on Receipt: Which Invoice Terms Get You Paid Fastest?

A plain-language comparison of the most common payment terms — and the one change most freelancers can make today that cuts average days-to-pay by more than a week.

Payment terms are the single lever on an invoice that affects when the money arrives — and most freelancers never change the default. Net-30 is the industry standard because it’s the industry standard, not because it’s the best choice for a one-person business. Shortening terms to Net-15 or Due on Receipt, when your client mix allows it, cuts average days-to-pay by a full week or more and smooths out the cash-flow pain that makes running a service business exhausting.

Below is a side-by-side of every common option, what each one actually delivers in practice, and a recommendation for what to use if you’re setting terms for the first time.

What the terms mean

“Net” in “Net-30” means the full amount is due, with no early-payment discount built in. The number is the window — 30 days from the invoice date. So Net-15 means 15 days. Net-7 means 7 days. Due on Receipt means pay it now.

Some invoices add a discount clause like 2/10 Net 30, meaning the client gets a 2% discount if they pay within 10 days, otherwise the full amount is due in 30. It’s more common in wholesale and distribution than in service work, but it’s a useful tool for incentivising early payment without shortening the headline term.

The comparison table

Term	Window	Avg. days to pay	Best for
Due on Receipt	0 days	~8 days	Small amounts, one-off work, repeat clients you trust to pay fast
Net-7	7 days	~12 days	Freelancers with small-business clients; weekly-billing contracts
Net-15	15 days	~21 days	Service businesses, recurring retainers, contractors
Net-30	30 days	~38 days	B2B default; larger clients with formal AP cycles
Net-60 / Net-90	60 or 90 days	~70 to 100+ days	Enterprise buyers who mandate it; high-margin work that can absorb the float

Average days-to-pay figures are aggregates from published small-business and freelance invoicing data; actual numbers vary by industry and client mix.

Net-30: the default no one questions

Net-30 became the B2B default in the mid-twentieth century because cheques took a week to arrive and another week to clear. That’s no longer true — almost no invoice is paid by physical cheque in 2026 — but the convention stuck because enterprise accounts payable systems are built around it.

In practice, Net-30 produces an average of around 38 days from invoice to payment. That’s because most clients process invoices in weekly or bi-weekly AP cycles and pay near the due date, not when the invoice arrives. Some slip 5 to 10 days past the deadline without intending to be late, just because of cycle timing.

If your clients are large companies with formal purchase-order workflows, Net-30 is the path of least resistance — anything shorter will get flagged by their AP team and bounced back for renegotiation. For everyone else, it’s leaving money on the table.

Net-15: the quiet upgrade

Net-15 is the single most under-used term for freelancers and small service businesses. It cuts expected days-to-pay from ~38 down to ~21, without triggering the “this feels aggressive” reaction that Due on Receipt sometimes does.

Most small-business clients accept Net-15 without pushback when it’s on the original contract. The resistance appears if you try to shorten terms mid-relationship — framing it as “my standard terms going forward” on a new project or retainer is the clean move.

For enterprise clients with a hard Net-30 policy, Net-15 won’t stick. You can still offer a 2% discount for payment within 15 days, which some AP teams will take if their cash position allows.

Due on Receipt: for small and trusted work

Due on Receipt works best for two situations: one-off work under $1,000, and recurring work with repeat clients you already trust to pay fast. A $200 invoice marked Due on Receipt will typically land in your account within a week. A $20,000 invoice marked Due on Receipt often gets treated like Net-30 anyway, because the client’s AP system simply doesn’t process large amounts same-day.

For coaches, designers, and other solo operators who bill small-to-mid amounts, Due on Receipt is probably the single highest-leverage change they can make. Combined with automatic reminders from day one, it’s realistic to see average days-to-pay drop below 10.

Whatever terms you pick, reminders still matter

Shorter terms help, but the real lever is consistent follow-up: a polite reminder on the due date, a firmer one a week after, and so on. PayNudge runs that sequence automatically on every invoice — works with Net-30, Net-15, or Due on Receipt, and stops the moment payment clears.

Net-60 and Net-90: mostly avoid

Net-60 and Net-90 are common in enterprise procurement, retail supply chains, and large construction contracts. If you’re not in one of those industries, a client asking for Net-60 is usually doing it for cash-flow reasons of their own — and you’re being asked to finance them at zero interest.

Running the numbers: a $10,000 Net-60 invoice, at an 8% annual cost of capital, is roughly $130 of foregone interest. On a thin-margin service business, that’s real money. Either push back on the terms, or price that cost of capital into the invoice total — it’s often easier to add 2% than to shorten the terms.

If you must accept Net-60 or Net-90, get an even larger deposit upfront — 50% rather than 30% — and make sure the contract allows you to pause work if any milestone slips.

How to change your terms without losing clients

1. Change terms on new projects, not existing ones.

Don’t shorten Net-30 to Net-15 halfway through a retainer. Introduce the new terms on the next signed scope of work.

2. Frame it as a standard, not a request.

“My standard terms are Net-15 with a 50% deposit” lands much better than “Would you be willing to pay faster this time?”

3. Offer a clean fallback.

For clients whose AP policy locks them into Net-30, offer a 2% discount for payment within 10 days. Half of them will take it.

4. State the terms on every invoice, not just the contract.

Clients pay from the invoice, not the contract. “Payment due in 15 days (by [date])” at the top of the PDF does more work than any legal clause.

The recommendation

For a freelancer or small service business in 2026 with mostly small-business clients, the default should be Net-15 with a deposit — typically 30% to 50% upfront on anything over a few thousand dollars.

For one-off work under $1,000, use Due on Receipt— the amount is small enough that clients don’t route it through formal AP, and same-week payment becomes realistic.

Only stay on Net-30for enterprise clients whose AP policy requires it, and even then, build in a late-fee clause and automatic reminders so the 30 days don’t stretch into 45 by default.

Frequently asked questions

What does Net-30 mean on an invoice?

Net-30 means the full invoice amount is due 30 days from the invoice date, with no early-payment discount. It's the most common default in B2B and professional services, but it also produces the longest days-to-pay metric because most clients pay near the deadline, not when the invoice arrives.

Is Net-30 calculated from the invoice date or the delivery date?

By default, Net-30 runs from the invoice date, which is the date on the invoice PDF — not the date work was completed. Some contracts specify Net-30 from receipt of invoice, which starts the clock when the client actually receives the email. Always state this explicitly on the invoice to avoid disputes.

Can I charge a late fee on a Net-30 invoice?

Yes, if your invoice or contract includes a late-fee clause. Standard language is '1.5% per month on outstanding balances after the due date', which is the legal cap in many US states. Without a late-fee clause in writing, you generally can't apply fees retroactively — but you can add them to future invoices.

What's the difference between Due on Receipt and Net-0?

Functionally they're the same — both mean payment is due immediately. Due on Receipt is more common in small business and freelance invoicing; Net-0 is more common in enterprise AP systems. Either way, accounts payable teams typically treat them as a 5-to-10-day payment window, not literally same-day.

Is it legal to demand shorter payment terms?

Yes — payment terms are a negotiable part of the contract, not a regulated standard. You can set Net-15, Net-7, or Due on Receipt as your default, and clients who don't like it can negotiate or not hire you. In the UK, the Late Payment of Commercial Debts Act sets 30 days as a statutory maximum for B2B unless otherwise agreed.
