Net 30 vs Due on Receipt: Which Payment Terms Get You Paid Faster

Most invoice templates say Net 30 because most invoice templates were copied from a corporate one. Very few solo businesses ever decide on their terms — they inherit them, then spend the next several years wondering why money is always three weeks away.

Terms are not a formality on the bottom of a PDF. They’re the size of an interest-free loan you make to every client, renewed every month, for as long as you work together.

What Terms Actually Cost You

The number that matters isn’t the wait, it’s the balance permanently parked in someone else’s account. It’s one multiplication:

Working capital tied up = (monthly billing ÷ 30) × average days to payment

At $3,000 a month, you’re billing about $100 a day. Here’s what each set of terms does with it, using the average days-to-payment observed across a real worked quarter for a one-person studio (the twelve invoices are here):

Days-to-payment are the actual averages from that quarter’s paid invoices; Net 45 is estimated using the same eight-day slippage observed on Net 30, since only one Net 45 invoice had been paid.

Read the Net 30 row again. A business billing $3,000 a month on Net 30 terms is running with $3,800 of its own money — more than a full month of revenue — sitting inside client accounts at all times. That’s not a cash-flow problem you can budget your way out of. It’s structural, and it’s the reason profitable freelancers still can’t cover a slow February.

Moving that client to Net 15 frees about $2,500 permanently, on the same revenue, with the same work. There is no other lever in a small business that returns $2,500 for one conversation.

Terms Slip, and the Slip Is Predictable

Nobody pays on the due date. They pay on their cycle.

In that worked quarter, one client paid on day 37 and day 39 on Net 30 terms — an eight-day slip, twice, consistently. That’s not a delinquent client; that’s an accounts-payable department running a fortnightly or monthly payment run, and your invoice landing wherever it lands in it.

Which produces the most useful rule in this article:

Set terms so that the client’s habitual slip still lands where you need the money.

If a client reliably pays 8 days late, Net 30 gets you paid on day 38 and Net 15 gets you paid on day 23. You don’t need to fix their behaviour. You need to stop financing it. Your invoice tracker should be calculating days-to-payment per client automatically — that column is what tells you which clients to move and by how much.

When Net 30 Is Genuinely Correct

Net 30 isn’t wrong, it’s over-applied. Grant it deliberately when:

• The client is a company with a real AP process. Larger organisations pay on cycles, and demanding due-on-receipt from one produces a “yes” that means nothing operationally.
• Government or institutional work. Terms are usually fixed by the contract, not by you.
• The relationship is long, the client is reliable, and the volume justifies it. Being the vendor who’s easy to work with has value — just price it knowingly.
• You’ve priced it in. If Net 30 is a condition of the work, the rate can reflect it.

And when it isn’t:

• A first project with any new client. You have no payment history. Due on receipt, or a deposit — how to structure and track one.
• Individuals and small owner-run businesses. They pay from a bank account, not a cycle, and Net 30 just gives them 30 days to forget.
• Small amounts. A $400 invoice on Net 30 costs more in follow-up attention than the terms could possibly be worth.
• Any client with an overdue balance already. Terms are a privilege that resets when the account is clear.

The Early Payment Discount Trap

“2/10 Net 30” — 2% off if they pay within 10 days, otherwise full amount at 30 — is a standard trade-credit term and, for most solo businesses, a bad deal dressed as a smart one.

The standard cost-of-trade-credit calculation:

(discount ÷ (1 − discount)) × (365 ÷ (net days − discount days)) = (0.02 ÷ 0.98) × (365 ÷ 20) = 37.2% annualised

You’re paying an effective 37% a year to be paid 20 days earlier. A 1/10 Net 30 discount works out at about 18.4% — cheaper, still expensive.

Compare that with simply invoicing Net 15 and charging full price. Same money, three weeks earlier, no discount at all. The discount only makes sense if you have a genuinely urgent, more expensive cash-flow gap you’d otherwise finance another way.

How to Change a Client’s Terms Without a Conversation That Hurts

Terms change at natural boundaries. Use one:

1. At the start of a new project or a new year. “Just so you have it, my standard terms are Net 15 from this project onward” attached to a proposal is a statement, not a negotiation.
2. When you raise rates. Terms travel quietly alongside price.
3. After a late payment. “I’m moving new invoices to Net 15” is a proportionate, non-punitive response to a slip, and much easier to say than a late-fee conversation. If you do want a fee attached, here’s what it should actually be.

Three practical details make new terms stick:

• Put the due date on the invoice as a date, not as “Net 15”. “Due 4 March” is unambiguous; “Net 15” requires the reader to do arithmetic they won’t do.
• Send to accounts payable, cc your contact. Terms can’t be met by someone who never receives the invoice.
• Store default terms per client in your tracker so every invoice inherits the right ones and you’re never re-deciding.

The Ten-Minute Version

Open your invoice log, calculate days-to-payment for every paid invoice, and average it by client.

You’ll get one of two answers. Either your clients pay roughly on terms — in which case your cash-flow gap is a terms problem and you can fix it with one email each. Or they slip consistently by a predictable margin — in which case you already know exactly how many days to pull your terms in by.

Either way it’s arithmetic on data you already have, and it’s worth more than any chasing you’ll do this quarter.
