Definição
NET 30 is the most common B2B payment term in the US and UK. The word "net" signals that no early-payment discount applies — the full amount is owed by the due date.
The 30 days are typically counted from the invoice date, though some contracts specify end-of-month (EOM) or goods-received (GR) as the start point — always clarify the base in your terms to avoid disputes.
Popular variations: NET 7 (common for freelance / fast-turnover services), NET 14, NET 15, NET 45 (mid-market B2B), NET 60 (enterprise procurement), NET 90 (global supply chain). Shorter terms help cash flow; longer terms are often forced on small suppliers by large buyers.
If a client misses the due date, statutory interest can apply automatically in B2B transactions under the UK Late Payment of Commercial Debts Act 1998, EU Directive 2011/7, and similar regulations — typically central bank base rate + 8%.
Invoice dated 1 January with NET 30 terms is due 31 January. If the client pays on 15 February, statutory late-payment interest accrues from 1 February at the applicable rate.
