What Is Net 90? Payment Terms Explained

Net 90 means the full invoice amount is due within 90 calendar days of the invoice date, a full quarter of a year. It is the longest standard payment term in routine commercial use and is most common in large enterprise procurement, publishing, and certain manufacturing supply chains.

How Net 90 Works

An invoice dated April 1 with Net 90 terms is due June 30. As with other Net terms, the 90 days are traditionally calendar days. You can find the exact due date for any invoice using the Net 90 Calculator.

Ninety business days, if a contract were to specify that, would be approximately 126 calendar days, or more than four months. This is uncommon, but worth confirming if your contract is ambiguous.

Who Uses Net 90

Net 90 terms appear most often in three contexts. First, large enterprise and government buyers use them as standard procurement policy, particularly for capital goods, software licenses, and professional services engagements. Second, the book publishing industry has historically used Net 90 for payments to authors and distributors. Third, some manufacturing supply chains use Net 90 where the production and inventory cycle is long enough to make shorter terms impractical for the buyer.

The Cash Flow Reality of Net 90

For a small business or independent contractor, Net 90 is a serious financial commitment. You are effectively extending an interest-free loan to your client for three months. On a $10,000 invoice, that is $10,000 of working capital tied up for a quarter.

Before agreeing to Net 90, do the math on your own cash flow. Calculate whether you can cover operating expenses for 90 days without that payment. If you cannot, either negotiate shorter terms, require a deposit upfront, or factor the cost of the float into your pricing.

Alternatives to Net 90

If a client insists on Net 90, consider these alternatives. A 50% deposit upfront with Net 90 on the balance splits the risk. Milestone-based payments, paid upon completion of defined project phases, avoid the single long wait entirely. Invoice factoring companies will advance you 80 to 90 percent of the invoice value immediately in exchange for a fee, which may be worth it on large invoices with reliable enterprise clients.

FAQ

Is Net 90 normal?

It is normal in certain industries and for certain buyer types, including large enterprises, government contractors, and publishing. For small business-to-business transactions or freelance work, it is on the long end and worth negotiating.

What is the difference between Net 90 and 90-day payment terms?

They mean the same thing. "Net 90" and "90-day payment terms" are interchangeable in practice.

Can I charge late fees on overdue Net 90 invoices?

Yes, if your contract includes a late fee clause. State laws vary on the maximum allowable late fee and interest rate. Including a clear late fee provision in your contract before you start work is the best way to ensure you can enforce it.
