NET 30, NET 60, NET 90: how ad network payment terms really work
"We pay NET 60." It sounds like a detail, but for a publisher it is the difference between getting paid in two months and extending an interest-free loan to a company you barely know. Payment terms are the clause that decides how much credit you give an ad network, for how long, and what happens if the money does not arrive. This guide explains what the terms really mean and where publishers most often get caught.
What NET 30, NET 60 and NET 90 actually mean
The number is the days the network has to pay after an invoice is issued — but the clock rarely starts when you serve the impressions. In most ad deals it starts at the end of the billing month, after the network has finished reconciling the numbers. In practice:
- NET 30 means an impression served on 1 March is typically paid around 30 April: about 60 days of exposure.
- NET 60 stretches that to roughly 90 days.
- NET 90 means a quarter of your inventory is, at any moment, an unpaid receivable.
The longer the term, the larger the amount you are exposed to if anything goes wrong. Many legitimate networks use NET 45 or NET 60 and honour it. The point is not that long terms are suspicious by themselves, but that they multiply your risk.
Where publishers get caught
- The clock starts late. "30 days from approval of the invoice" or "from receipt of the advertiser's payment" can move the date indefinitely. Prefer wording tied to a fixed date, such as the last day of the billing month.
- "Paid when the advertiser pays." A pay-when-paid clause transfers the advertiser's credit risk to you. If you accept it, you are lending to every advertiser the network works with.
- Invoices you cannot issue. If you must wait for the network's own report before invoicing, they control the start date.
- Terms that quietly change. A contract that lets the network amend terms by publishing them on its site can turn NET 30 into NET 90 without a signature.
- Payout thresholds. Even on time, nothing is due until your balance passes the minimum. If that figure can change, the term is meaningless. We cover that in a separate guide.
How to protect yourself
- Negotiate the shortest term you can. Weekly or bi-weekly payment for new relationships is common for publishers with real traffic.
- Cap your exposure. Decide the maximum unpaid balance you can tolerate and reduce delivery when you reach it.
- Get the first payment before you scale. Treat the first cycle as a pilot. See our guide on vetting an ad network before you monetize.
- Keep your own numbers. Export your ad-server data every month. You will need it to invoice and to dispute.
- Calendar the due date. The day after a missed payment is the day to ask in writing, not a month later.
Frequently asked questions
Is NET 60 a red flag? No. It is common in advertising. It becomes a concern when combined with other signals, such as unclear legal entities or a shifting payout threshold. See 10 signs an ad network may not pay you.
What if the network pays late once? Ask in writing, record the date, and reduce exposure until the next cycle clears. One delay is a question; a pattern is a warning.
The bottom line
Payment terms are the price of the credit you give. Read them as a lending decision, shorten them where you can, and never let the amount you are owed grow faster than your confidence in the payer.
