Net 30 Terms
Net 30 terms are payment terms requiring the buyer to pay the full invoice amount within 30 days of the invoice date, or another agreed starting point such as delivery.
Net terms tell a business customer how long it has to pay. Under net 30, the full amount, or the net amount, is due 30 days after a starting date, usually the invoice date. Variations include net 15, net 45, net 60, and terms tied to the end of the month. Sellers sometimes offer an early payment discount, written as '2/10 net 30,' which means the buyer can take a 2 percent discount if it pays within 10 days, otherwise the full amount is due in 30.
In B2B collections, net terms define when an invoice becomes past due, which drives the aging report, late charges, and escalation rules. The terms should be stated clearly in the credit application and on every invoice so there is no argument about the due date. A common issue is a customer that unilaterally pays on its own schedule, such as net 60, because its accounts payable policy says so. Unless the seller agreed to those longer terms, the original terms usually still control.
For example, a fictional print shop, Elm Street Graphics, invoices a marketing firm $7,500 on March 1 under net 30 terms. Payment is due March 31. On April 15 the invoice is 15 days past due and shows up in the 1 to 30 day bucket of the aging report. Elm Street follows its process: a reminder on day 5, a call on day 15, a written notice on day 30, and a decision about credit hold and outside collection by day 60.
Clear net terms matter to a creditor because every later step depends on them. Late payment interest typically runs from the due date, the debtor's default is measured against it, and a court will look to the agreed terms when calculating what is owed. Consistently enforcing terms also signals to customers that the due date is real.
Example
Elm Street Graphics invoices $7,500 on March 1, net 30. Payment is due March 31; by April 15 the invoice is 15 days past due and enters the follow-up process.
