Net 30
Is net 30 always based on the invoice date?
Most references describe net 30 as 30 days from the invoice date, but contracts or procurement policies can specify another trigger, such as receipt of invoice or receipt of goods.
Does net 30 mean business days?
No; net 30 generally means 30 calendar days, including weekends and holidays.
How does net 30 differ from 2/10 net 30?
2/10 net 30 offers a 2% discount if the invoice is paid within 10 days; otherwise, the full amount is due in 30 days.
Net 30 is a trade credit payment term requiring the buyer to pay the full invoice amount within 30 calendar days of the invoice date. The 'net' refers to the net amount due after discounts, and '30' specifies the payment window. It functions as interest-free vendor financing, letting the buyer receive goods immediately while deferring cash outflow.
On a manufacturing shop floor, net 30 is the standard credit term for raw materials, MRO supplies, packaging, and spare parts. Production consumes material immediately while the invoice sits in accounts payable, preserving cash during long lead times. Warehousing interacts with AP because goods are received and issued to production before payment is finalized; the three-way match among receipt, purchase order, and invoice determines whether the clock runs cleanly. A recurring supplier cadence creates a predictable working-capital rhythm tied to receipt date, invoice date, and due date in ERP systems. The real benefit is inventory continuity: stock can be built and consumed before cash leaves the business. But this only works if AP controls keep unpaid receipts visible. Without disciplined tracking, receipts age into exceptions, suppliers tighten credit, and replenishment stalls. In high-volume plants, net 30 supports stable material flow when managed as a scheduled obligation rather than free inventory.
Invoice-date mismatch: If the AP system clocks from invoice date but the contract specifies receipt or goods acceptance, invoices get paid early or flagged overdue, triggering supplier disputes and audit exceptions.
Production-supply overreach: Treating net 30 as free inventory encourages overbuying raw materials, inflating on-hand stock, hiding demand errors, and eventually creating obsolescence or storage bottlenecks despite the deferred cash payment.
Receiving and match delays: When goods are received but packing slips, PO lines, and invoices do not align, invoice approval stalls, suppliers view payment as late, and vendor relations erode, potentially disrupting future shipments.
