Business Payment Terms: Net 30, Net 45, Net 60 and When to Change Them
Your payment terms decide how long your money sits in someone else's account. Set them by habit and you finance your customers for free. Here is how to think about Net 30 versus longer terms, when to adjust them, and how to spot terms that are quietly starving your cash flow.
What's inside
What payment terms actually do
Payment terms are not just a number on the invoice. They set how long you wait to be paid, and every day in that window is a day you are funding your customer's business instead of your own. Generous terms can win and keep good accounts. Terms set purely out of habit, with no thought to your cash position or the customer's risk, quietly cost you money you never see leave.
What do Net 30, Net 45 and Net 60 mean?
Direct answer: the number is how many days your customer has to pay the invoice in full. Net 30 means 30 days, Net 45 means 45 days and Net 60 means 60 days. The clock usually starts on the invoice date. If you mean something else, like the delivery date or the end of the month, say so in your written credit terms.
- Net 30 is the common default in B2B. It suits most established accounts and gives you an early, clear point to follow up when a payment is late.
- Net 45 sits in between. It is common with larger buyers whose payables department pays on a set schedule and asks for more time than Net 30. You wait 15 more days for your money, so offer it to accounts with a clean payment record.
- Net 60 doubles the time you finance the customer compared with Net 30. Keep it for large, reliable accounts you want to win or keep, and build that cost into your pricing.
You will also see early payment terms like 2/10 Net 30. The customer takes a 2 percent discount for paying within 10 days, and otherwise the full amount is due in 30. That can pull cash in faster, but the discount comes out of your margin, so offer it where faster cash is worth more to you than the discount.
Is Net 30 really your best default?
Net 30 is the reflex for most businesses, but a default is not the same as the right answer. For a new or higher risk account, Net 30 may be too much rope, and shorter terms or a deposit protect you while trust is built. For a large, dependable customer you want to keep, longer terms can be a competitive advantage worth offering on purpose. The point is to choose terms deliberately per account, not to apply the same 30 days to everyone because that is what the template said.
When and how to adjust terms
Terms are not permanent. As you learn how an account actually pays, the terms should move with it. A customer who has paid cleanly for a year may have earned longer terms or a larger line. One that has started slipping should be moved to shorter terms, or to prepayment, before a slow account becomes a bad one. When you tighten terms, do it in writing, give reasonable notice, and tie it plainly to their payment history so it reads as policy, not punishment.
Do not be afraid to change terms
Many creditors leave bad terms in place for years because changing them feels confrontational. It is not. Adjusting terms is a normal part of managing credit, and customers who value the relationship will understand a fair, clearly explained change. The ones who react badly to any accountability are often the very accounts you most needed to tighten. Protecting your own cash flow is not something to apologize for.
When your terms are quietly slowing your cash
Sometimes the problem is not a single slow customer, it is your own terms working against you. If a large share of your receivables sits past due, or your average days to collect keeps climbing, the terms themselves may be too loose for the accounts you carry. Watch how quickly money actually comes in against the terms you set. When the gap grows, that is the signal to tighten terms, add deposits on riskier accounts, or make late payment cost the customer something.
When terms are met with silence
Clear terms only work when they are enforced. If an account blows past its terms and stops responding, working it and then placing it for B2B debt collection beats letting it age. Our team recovers commercial debt while keeping good customers intact.
Frequently asked questions
What does Net 45 mean on an invoice?
Net 45 means the customer has 45 days to pay the invoice in full, usually counted from the invoice date. It is longer than the Net 30 default and is usually offered to larger customers with a solid payment record.
What is the difference between Net 30 and Net 60?
Net 30 gives the customer 30 days to pay and Net 60 gives them 60. Net 60 doubles the time you finance the customer, so save it for large, reliable accounts and make it a deliberate choice, not a default.
Is Net 30 the best payment term for a small business?
Not automatically. Net 30 is a common default, but the right term depends on the account. New or higher risk customers may warrant shorter terms or a deposit, while large, reliable customers may be worth longer terms offered on purpose. Choose terms per account rather than applying the same 30 days to everyone.
Can I change a customer's payment terms after we have started?
Yes. Terms should move with a customer's payment history. Tighten them for accounts that are slipping and consider extending them for accounts that have earned it. Put changes in writing, give reasonable notice, and tie them clearly to payment history so it reads as policy.
How do I know if my payment terms are too generous?
Watch your receivables. If a large share sits past due or your average days to collect keeps climbing, your terms may be too loose for the accounts you carry. That is the signal to shorten terms, add deposits on riskier accounts, or attach a cost to late payment.
