Net 30

Net 30 is a payment term indicating that the full amount of an invoice is due within 30 days of the invoice date. It is one of the most common B2B credit terms, effectively giving the buyer a short, interest-free window to pay.

Why it matters in B2B sales

Net terms are a quiet but real part of every deal's economics. Offering Net 30 can make a seller easier to buy from, but it also delays cash and shifts short-term financing onto the seller.

Because terms affect both closing and cash flow, they are negotiated alongside price and belong in the proposal, not sprung at invoicing. They are one specific case of broader payment terms, and the choice between Net 15, Net 30, and Net 60 can matter as much to a cash-conscious business as the headline price.

How net terms work

"Net" refers to the full invoice amount, and the number is the days until it is due. Net 30 means payment in full within 30 days; Net 60 within 60, and so on. Sellers sometimes attach an early-payment discount, written as, for example, "2/10 Net 30", meaning a 2% discount if paid within 10 days, otherwise the full amount at 30. It is a simple lever to pull cash in faster.

Net 30 vs due on receipt vs Net 60

The trade-off is speed of cash versus buyer friction. "Due on receipt" gets cash in fastest but can deter buyers used to credit terms. Net 60 is buyer-friendly but strains the seller's cash flow. Net 30 is the common middle ground, familiar to most B2B buyers and manageable for most sellers, which is why it has become something of a default.

A concrete example

A supplier invoices a customer on Net 30 and, to encourage faster payment, offers "2/10 Net 30", a 2% discount if paid within 10 days, otherwise the full amount at 30. The customer takes the discount, and the supplier gets paid three weeks early, improving cash flow at a small, deliberate cost.

How it shows up in a modern proposal workflow

Terms like Net 30 should be stated consistently across quote, proposal, and contract, a mismatch here creates awkward disputes at invoicing. Cobl pulls agreed terms into every document it generates, so the sales proposal, purchase order, and invoice all reflect the same payment expectations.

That consistency means the payment terms the buyer agreed to during the sale are exactly what appears when it's time to pay, with no surprises to slow collection.
