Net 30 vs Net 15 vs Due on Receipt

Most freelancers write Net 30 because it is what they saw on someone else's invoice. It is a reasonable default and it is also the least examined decision on the document. Shorter terms are not automatically faster, and there is a lever that beats changing the terms at all.

What the terms actually mean, and where 30 came from

Net 30 means the full amount is due thirty days from the invoice date. Net 15 means fifteen. Due on receipt means immediately. "2/10 Net 30" adds an early-payment discount: 2% off if paid within ten days, otherwise the full amount in thirty. The "net" is simply an old accounting word for the amount after any discounts — it carries no other meaning, and it is worth knowing because "Net 30 EOM" (end of month) shifts the start of the count to the end of the month the invoice was issued in, which can quietly add another four weeks.

Thirty days is a convention inherited from an era of posted invoices, monthly ledgers and cheques. It survives because it is what corporate accounts payable systems are configured around, not because anyone re-derived it. That matters in both directions: it means Net 30 is safe and unremarkable to a corporate client, and it means nobody at that company is going to be surprised or offended by anything shorter — they will simply pay to whatever their system says, which may not be your number at all.

The other thing to write down, every time, is the actual due date alongside the term. "Net 30" is a rule; "due 16 October 2026" is a fact. To a small customer the term means nothing at all, and to a large one the date is what makes a reminder concrete rather than a discussion about when the clock started.

Shorter terms are not automatically faster

The intuitive move when cash is tight is to cut Net 30 to Net 15. It often changes nothing, and understanding why is the most useful thing in this guide.

Companies of any size do not pay invoices on their due dates. They run payment cycles — weekly, twice monthly, or monthly — and an approved invoice waits for the next run regardless of what your terms say. If a client runs payments on the 10th and 25th, an invoice you marked Net 15 and sent on the 3rd is not paid on the 18th. It is paid on the 25th, exactly as a Net 30 invoice sent the same day would have been. You have gained nothing and introduced a term you are now technically enforcing against someone who did nothing wrong.

Worse, terms you do not enforce teach the client that your numbers are decorative. If you write Net 15 and then say nothing until week six, you have established that the real deadline is somewhere past six weeks, and the next invoice will be treated accordingly. Shorter terms only work if you are willing to follow up when they are missed — so pick a window you will actually act on.

The question worth asking a new client, once, at the start, is not "can you do Net 15?" but "when do your payment runs happen?" That one answer tells you more than any term you could write. For a client on a twice-monthly cycle, the highest-value thing you can do is get the invoice in before the cut-off, which is a scheduling decision rather than a contractual one.

Where shorter terms genuinely work is with clients who pay you directly rather than through a finance process — sole traders, small agencies, homeowners, anyone whose "accounts payable" is a person with a card. There, Net 15 is paid in fifteen days and Due on receipt is often paid the same day.

What an early-payment discount really costs

A 2/10 Net 30 discount looks small. Two percent to be paid twenty days sooner sounds like a cheap way to improve cash flow, and it is by far the most common term people copy without pricing it.

Annualise it. You are giving up 2% of the invoice to accelerate payment by twenty days. There are roughly 18.25 twenty-day periods in a year, and the discount is 2% of the amount you would otherwise receive — about 2.04% of what you actually get. That works out to an effective annual rate of roughly 37%. You would not borrow at 37% to cover a three-week gap; offering 2/10 Net 30 is economically the same decision.

That does not make it wrong. If the alternative is a credit card at 24%, or a factoring arrangement, or genuinely not making payroll, 37% for twenty days is a rational price for certainty. The error is offering it as a default because it appears on other people's invoices, without noticing that it is the most expensive line on the document.

There is also a behavioural trap. Many accounts payable departments run automated discount capture — if a discount is available and the invoice clears approval in time, their system takes it without anyone deciding to. So a discount you offered as a gesture will be taken every single time by exactly the clients who were going to pay you on schedule anyway. Only offer it if you would be happy for every eligible client to take it, because they will.

Due on receipt, and when it reads badly

Due on receipt is the right term far more often than freelancers use it, and the wrong term in one specific situation.

It fits any transaction that completes in person or on delivery — a repair finished in a driveway, a session delivered, a file handed over, a small job for a homeowner. The customer is present, the work is visibly done, and there is no reason to introduce a thirty-day gap into a moment where payment is frictionless. Trades that switch from "I will send an invoice" to writing it on the spot with Due on receipt typically collect faster, not because the term is stronger but because the moment is.

Where it reads badly is with a corporate client who has a finance process. Due on receipt is not a term their system can act on, and marking a B2B invoice that way signals either that you do not know how their side works or that you expect special handling. It will be paid on their cycle regardless, and you will have spent a little credibility for nothing. For those clients, Net 30 with the date written out is the professional default.

For new clients of any size, the stronger instrument is not a short payment term at all — it is a deposit. Thirty to fifty percent up front caps your exposure and filters out the clients who were never going to pay, which is something no payment term can do. A deposit plus Net 30 on the balance is a better position than Net 15 on the whole amount.

The lever that beats changing the terms

Invoice the day the work is accepted, not at the end of the month.

Month-end batching is the single most common self-inflicted delay in freelancing, and it is invisible because it feels organised. If you finish a job on the 3rd and invoice on the 31st, you have added twenty-eight days before any payment term begins. No change to the term recovers that. Cutting Net 30 to Net 15 saves fifteen days; invoicing on completion saves twenty-eight — and the two are not alternatives, they compound.

The worked example below prices this out. The same piece of work, the same client, the same amount, billed four different ways: sixty-three days to cash at one end and seven at the other, with the largest single improvement coming from changing when the invoice was sent rather than what it said.

If batching exists because raising invoices is tedious, that is the thing to fix. Invoicing on completion only works if it takes two minutes, which is an argument for a template you can fill in on site or a generator that produces the PDF while the work is still fresh.

Example

A freelance designer finishes a $3,480.00 project on Friday 3 October for a mid-sized company that runs payment cycles twice a month, on the 10th and the 25th. The work, the client and the amount are identical in all four cases. Only the invoicing behaviour changes.

A — month-end batch, Net 30	Invoiced 31 Oct · due 30 Nov · paid 5 Dec
B — invoiced on completion, Net 30	Invoiced 3 Oct · due 2 Nov · paid 10 Nov
C — invoiced on completion, Net 15	Invoiced 3 Oct · due 18 Oct · paid 25 Oct
D — invoiced on completion, 2/10 Net 30	Invoiced 3 Oct · discount taken · paid 10 Oct
Cost of the discount in D	$69.60 — she receives $3,410.40
Effective annual rate of that discount	about 37%

Same work, same client: 63 days to cash in A, 7 days in D — and the biggest single jump came from the invoice date, not the terms.

A to B is the whole argument. Nothing about the terms changed — both are Net 30. She simply invoiced on the day the work was accepted instead of at month end, and payment arrived 25 days sooner. That is a larger improvement than anything available by negotiating terms, and it costs nothing and requires no conversation with the client.

B to C is the move most freelancers reach for first, and it is worth less than it looks. Net 15 made the invoice due on 18 October, but the client pays on the 10th and the 25th, so it was paid on the 25th. She gained sixteen days over B — real, but half of what the invoice date was worth, and it came with an obligation to chase if the 25th had slipped.

C exposes the thing that makes payment terms unpredictable: the due date and the payment date are different systems. Her Net 15 invoice was paid seven days late by her terms and exactly on time by theirs. If she sends a stern reminder on the 19th she is technically right and practically wrong, and it costs her goodwill with a client who did nothing unusual.

D is fast and expensive. Taking 2% off to be paid on 10 October rather than 10 November — which is when B actually landed — costs $69.60 on a $3,480.00 invoice, at the effective annual rate of roughly 37% worked out earlier. If she needs the cash that week, that is a defensible price. If she does not, she has given away $69.60 to a client who would have paid on schedule anyway, which is what automated discount capture guarantees will happen.

The order of the levers is the takeaway. Invoice on completion first, because it is free. Ask when their payment runs happen second, because it is one question and it tells you which terms are even meaningful. Take a deposit on new clients third, because it caps what you can lose. Change the payment term last, and only to a window you will actually enforce — and price the discount before you offer it.

Frequently asked questions

Is Net 15 better than Net 30 for freelancers?: Only with clients who pay you directly rather than through a finance process. A company running twice-monthly payment cycles pays on its cycle regardless of your term, so Net 15 changes nothing except giving you a deadline you now have to enforce. With sole traders, small agencies and individuals, Net 15 genuinely is paid in fifteen days.
What does 2/10 Net 30 mean and is it worth offering?: 2% off if paid within ten days, otherwise the full amount in thirty. Its effective annual cost is roughly 37%, which is worth paying if you need certainty that week and expensive if you do not. Note that many accounts payable systems capture available discounts automatically, so assume every eligible client will take it.
Should I use Due on receipt?: Yes for work that completes in person or on delivery, where the customer is present and payment is frictionless — trades, sessions, small jobs. No for corporate clients with an accounts payable process: their system cannot act on it, they will pay on their cycle anyway, and it reads as though you do not know how their side works.
How do I get paid faster without changing my terms?: Invoice the day the work is accepted rather than at month end. Batching at month end can add up to twenty-eight days before any term begins, which is more than you would gain by halving Net 30. After that, ask the client when their payment runs happen and get your invoice in before the cut-off.
Can I change payment terms on an existing client?: For future work, yes — state the new terms when you quote the next project rather than changing them on an invoice for work already done. Changing terms on an invoice the client has already authorised at different terms will bounce it back to someone for re-approval, which delays the payment you were trying to accelerate.
What terms should I use with a brand new client?: Net 30 on the balance and a deposit of 30% to 50% up front. The deposit does something no payment term can — it caps your exposure and filters out clients who were never going to pay. A short term on the full amount looks tougher and protects you far less.
