What does net 30 mean on an invoice?
By Tim White · Last updated
Net 30 on an invoice means the full amount is due 30 days after the invoice date. 'Net' refers to the total owed, and the number is the count of days you have to pay. Net 15 and net 60 work the same way with different windows. Missing these dates is how late fees and strained vendor relationships start.
How net terms work
If an invoice dated June 1 says net 30, payment is due by July 1. Some vendors offer an early-payment discount, written as '2/10 net 30', meaning a 2 percent discount if you pay within 10 days, otherwise the full amount by day 30.
Keeping track without a spreadsheet
Understanding net 30 is easy. The failure mode is losing track of dozens of due dates across dozens of vendors. InvoiceJet reads the due date off each invoice, tracks what is overdue, and sends a Monday cash-needs digest so you see what is due that week before anything slips.
Common mistakes
The usual slip is counting from the wrong start date. Net 30 runs from the invoice date, not the day you received it or approved it, and those can differ by a week. Watch for terms that are not day counts at all. "Net EOM" means the end of the month following the invoice date, which can give you far more time than a flat 30 days. Read the terms line before you assume 30 days from receipt.
Common questions
Does net 30 mean 30 business days or calendar days?
Calendar days, unless the invoice explicitly says business days. When in doubt, pay by the earlier date to be safe.
When does the net 30 clock start?
From the invoice date printed on the bill, not the day you receive or approve it, unless the invoice says otherwise. Some vendors use terms like net 30 EOM, which start counting at the end of the month the invoice is dated.
What is the difference between net 30 and due on receipt?
Net 30 gives you 30 days from the invoice date to pay in full. Due on receipt means payment is expected as soon as the invoice arrives, with no grace period.
