Invoice Payment Terms Explained (Net 30, 2/10 Net 30 & More)

Payment terms are the quiet agreement that decides when you get paid — and they matter as much to your cash flow as the price itself. Set them clearly and you get predictable income; leave them vague and you get slow payers, disputes, and awkward chases. This guide explains the common terms in plain English and how to choose the ones that fit your business.

What "payment terms" actually means

Payment terms are the conditions you set for getting paid: how long the customer has, when the clock starts, which methods you accept, and any discount or penalty attached. They belong on the invoice — but ideally they're agreed before the work starts, so nothing is a surprise.

The common terms, decoded

• Due on receipt — payment is expected as soon as the invoice arrives. Best for one-off jobs or new customers.
• Net 7 / Net 15 / Net 30 / Net 60 — payment is due that many days after the invoice date. Net 30 is the most common in B2B; shorter terms (Net 7–15) pull cash in faster.
• EOM (end of month) — due at the end of the month the invoice was issued. "Net 30 EOM" means 30 days after month-end.
• CIA / PIA — "cash in advance" / "payment in advance." The full amount is paid before you deliver. Common for custom or high-risk work.
• Deposit / 50% upfront — part paid before work begins, the balance on completion. Protects you on larger projects.
• Milestone billing — payment tied to stages of delivery, so cash arrives as the work progresses.
• Retainer — a recurring fixed amount, billed ahead, for ongoing work.

Early-payment discounts: "2/10 Net 30"

This is the one that confuses people. 2/10 Net 30 means: the full amount is due in 30 days, but if the customer pays within 10 days, they take a 2% discount. It's a tool to pull cash in sooner. Just weigh the cost — offering 2% to be paid 20 days early is a real discount, so use it where faster cash is worth more than the margin.

Start the clock on the right date

"Net 30" is meaningless if no one agrees what day zero is. Make it explicit: is it 30 days from the invoice date, the delivery date, or receipt of the invoice? Better still, state the actual due date ("Due: October 1, 2026") on the invoice. Specific dates get paid; relative terms get interpreted.

How to choose your terms

• Match your own cash cycle. If you pay suppliers on Net 15, collecting on Net 60 quietly finances your customers.
• Shorter for new or risky customers, more generous for trusted, high-value ones.
• Add a late-payment policy (a fee or interest) and state it up front — then apply it consistently.
• Make paying effortless — accepted methods and a payment link on every invoice.

Good terms only help if they're actually collected.
