What is Net 30?
SHORT ANSWER
Net 30 means the full invoice is due within 30 days of the invoice date. The supplier gives you the goods now and takes payment later.
Net 30 is credit. The supplier is financing your inventory for a month and carrying the risk that you do not pay.
Net 30 is a deadline, not a suggestion. Paying on day 35 under a Net 30 agreement is late, even if nobody calls.
For example
Invoice dated the 3rd on Net 30 terms is due by the 2nd of the following month.
Why it matters
Terms convert your cash from a constraint into a cushion — you can hold more inventory with the same money.
The mistake to avoid
Treating the due date as the start of a negotiation. Late payments shrink limits quietly and fast.
