Net 30 vs Net 60 vs Net 90: which payment term actually fits your business

Most small businesses default to Net 30 because it is the convention. That works for most service businesses but breaks in two specific situations: when your customer base expects longer terms (enterprise, government, healthcare) or when your own working capital cannot float 30 days of receivables comfortably.

Net 30 means payment is due 30 days from the invoice date. The convention dates back to early-1900s mercantile credit terms and survived because it loosely matches a monthly billing cycle. The hidden number behind Net 30 is the actual payment lag. Industry data on small service businesses puts average actual payment at roughly 42 days for invoices on Net 30 terms — meaning the convention quietly costs you about 12 days of float on every invoice unless you actively enforce.

Net 60 and Net 90 are common in B2B contracts where the customer is a larger organization with formal accounts-payable cycles. Agencies serving Fortune 500 clients, contractors building for institutional buyers, healthcare providers billing through TPAs — all routinely operate on Net 60 or longer. The customer often will not even agree to faster terms. Pushing back on Net 60 with an enterprise procurement team usually loses the work.

The hidden cost of longer terms is working capital. A $10,000 invoice on Net 90 means you are floating $10,000 of your operating cash for three months. At a 6 percent cost of capital, that is roughly $150 of carry per invoice. Acceptable on a single invoice, painful at portfolio scale. A small business with $500,000 of annual revenue on Net 90 is functionally underwriting a $125,000 line of credit to its customers, interest-free.

Net 14, Net 7, and Due on receipt are the shorter end. Due on receipt is most appropriate for retail, e-commerce, and any one-off transaction where there is no ongoing relationship. Net 7 and Net 14 work for trade customers in industries where cash-flow is tight on both sides (food service, small-batch manufacturing). Pushing a B2B customer from Net 30 to Net 14 is a real ask and usually has to be priced in: a small discount for early payment in exchange for the term cut.

How to actually pick: start with the industry default. Going against the grain costs deals unless you have real negotiating leverage. Then look honestly at your own cash-flow tolerance. If 30 days of receivables float already hurts, longer terms will quietly bleed you no matter what your customers expect. The last piece is enforcement: short terms with no follow-through is worse than long terms with a disciplined day-3 call routine.

Late fees and term length interact. A 1.5 percent monthly late fee on a Net 30 invoice that goes to day 45 is small in absolute terms; the same fee on a Net 90 invoice that goes to day 120 compounds to a more meaningful number. State law caps both: California caps commercial late-fee interest at 10 percent annual unless explicitly contracted higher; Texas allows broad latitude as long as the rate is in the original contract. The state-specific framework lives at /collections-laws.

The day-3-past-due principle applies regardless of term. Day 3 past due on Net 30 is calendar day 33 from invoice. Day 3 past due on Net 60 is calendar day 63. The clock starts when the term expires, not when the invoice was sent. The recovery curve from that point — 87 percent in the first week, 63 percent by day 30 of past-due, 41 percent by day 60 — is the same shape across all term lengths.

What does not change with term length: the fact that email reminders alone collapse past day 14 of past due, that the phone call is what closes the gap, and that the customer who is going to pay usually pays in the first week of the chase. Whether the invoice is Net 14 or Net 90, the chase cadence is the same: day 3 past due, day 7 past due, day 14 past due.

What automates: the chase. The Syntharra AI voice agent reads your accounting platform's aging report and triggers calls based on past-due day count, not absolute calendar date. Net 30 customers get called on day 33; Net 60 customers get called on day 63; the rest of the cadence is identical. Pricing is success-fee only — ten percent of recovered amount, no monthly charge.
