You finish the work, send the invoice, and then wait. And wait. If that feeling is familiar, your payment terms are probably doing you no favours. Terms are the rules that decide when money actually lands in your account, and choosing them well is the difference between steady cash flow and a monthly scramble. Let us clear up what Net 30 really means and how to use terms to get paid faster.
So what does "Net 30" mean?
Net 30 means the full amount is due within 30 days of the invoice date. The word "net" just means the total owed after any discounts, so Net 15 is 15 days and Net 60 is 60. That is all there is to it. The only detail people trip over is when the clock starts. Usually it runs from the invoice date, but some businesses count from delivery or from the end of the month. Whatever you choose, put it on the invoice so nobody can claim confusion later.
The terms you will actually use
You do not need a finance degree here. A handful of options cover almost every situation:
- Due on receipt. Payment expected now. Good for one-off jobs and brand-new customers.
- Net 7 or Net 15. Short and cash-friendly. Popular with freelancers and small suppliers.
- Net 30. The business-to-business default. Fair to the customer, predictable for you.
- Net 60 or Net 90. Long terms that big buyers often demand. Only agree if your cash flow can survive the wait.
- 2/10 Net 30. A 2% discount if they pay within 10 days, otherwise the full amount in 30. A cheap, effective nudge.
- 50% upfront. A deposit before you start, balance on completion. Essential on larger projects.
Matching the terms to the customer
There is no single right answer, and that is the point. A new customer you have never dealt with should get short terms or a deposit, full stop. A reliable client of three years can have Net 30 without a second thought. If a large buyer insists on Net 60, that is fine, but price the cost of waiting into your quote rather than absorbing it silently. And whatever you agree, agree it before the work starts. Renegotiating terms after delivery is a losing game.
The habits that get you paid
Clear terms only work if the rest of your invoicing is sharp. These small habits move the needle more than any clever clause:
- Invoice the moment the work is done. Every day you delay is a day added to the wait.
- Write the actual due date, not just "Net 30". "Due 30 June" removes all doubt.
- Make paying easy: bank details and a pay-online link right there on the invoice.
- Add a late-payment line. Even a small monthly charge changes behaviour.
- Send a friendly reminder a few days before the due date, and again just after.
Why terms are really a cash-flow decision
Here is the part that catches growing businesses out. Every unpaid invoice is money you are lending your customer for free. Buy your materials on Net 15 but sell on Net 60, and you are funding a 45-day gap out of your own pocket. Do that across a dozen jobs and a profitable business can still run dangerously low on cash. Try to line up what you pay with what you receive, take deposits on the big jobs, and keep an eye on how long your customers actually take to pay. Shaving even a week off that average can change how the whole month feels.
A word on offering early-payment discounts
If late payment is a recurring headache, a small early-payment discount is often cheaper than the alternative. Losing 2% to get paid in ten days instead of thirty can be a bargain when the alternative is dipping into an overdraft or chasing the same customer three times. The trick is to treat it as a deliberate choice rather than a default. Offer it to customers who genuinely respond to it, keep it off invoices for clients who already pay on time, and always weigh the discount against what slow payment actually costs you. Run the numbers once and the decision usually makes itself.
Frequently asked questions
Does Net 30 include weekends?
Yes. It means 30 calendar days unless your terms specifically say business days.
Can I charge interest on late payments?
In most countries you can, as long as you state the late-payment terms on the invoice or in your contract beforehand.
What are the best terms for a freelancer?
Net 7 or Net 15 keeps your cash moving, ideally with a deposit on bigger projects. Save Net 30 for clients who have earned your trust.
When should the payment clock start?
Most businesses start it on the invoice date, but you can use the delivery date instead. Just pick one, state it clearly, and stay consistent.
