TL;DR

Net 90 is a three-month payment window. Only common in large enterprise or government contracts, it puts significant cash flow strain on smaller vendors and almost always warrants special pricing or financing consideration.

Key Points

✓

Net 90 is the longest standard payment term — anything beyond this is often negotiated case by case

✓

Research suggests collection rates drop significantly for invoices unpaid at 90+ days, making [[invoice-aging]] monitoring essential

✓

Vendors accepting Net 90 terms effectively provide their clients with a three-month interest-free loan

✓

Factoring companies specifically target Net 90 invoices as they represent the highest demand for immediate cash

When Net 90 Is Justified

Net 90 appears most often in large enterprise, government, and international supply chain contracts where payment runs through multi-tier approval processes¹. It's rarely appropriate for freelancers or small service businesses — the financial exposure is simply too large relative to most project sizes. If you encounter a client requesting Net 90, treat it as a negotiating signal rather than a fixed requirement. In most cases, pushing back for Net 60 or better will succeed, especially if you can offer an Early Payment Discount as an incentive.

The True Cost of Net 90

Accepting Net 90 has an implicit financial cost. If you invoice $10,000 today and receive payment in 90 days, you've provided an interest-free loan for three months. At an opportunity cost of even 6% annually, that's $150 of financing cost you're absorbing. Most small businesses don't factor this into their pricing. If you must accept Net 90, price the engagement 2–3% higher to offset the carrying cost, or factor the receivable through an Invoice Factoring service. Alternatively, require a Deposit at project start and milestone payments along the way to minimize the Net 90 exposure.

Monitoring Net 90 Receivables

Net 90 invoices require vigilant Invoice Aging tracking. Once an invoice passes its 90-day due date, recovery becomes significantly more difficult. Send an Invoice Reminder at the 75-day mark (two weeks before due), another on the due date, and escalate to a formal Late Payment Letter if payment doesn't arrive within one week of the due date. For high-value Net 90 invoices, consider proactively building a relationship with your contact in the client's Accounts Payable department — they can flag and expedite your invoice in their payment queue.
