Payment Terms That Get You Paid Faster
Published September 20, 2026
Most invoices say Net 30 because the one before them said Net 30. Payment terms are usually inherited rather than chosen — which is odd, because they decide when cash arrives, how much of it survives contact with the client's payment process, and how much leverage you have when it does not arrive at all.
This playbook picks the terms deliberately. It compares the four wordings that cover nearly every situation, prices the famous 2/10 discount honestly, shows how deposits and milestones split project risk, and ends with one clause and a collections timeline you can adopt this week. The tools linked along the way do the arithmetic; the point of the article is the judgment around it.
The short answer
Payment terms set when money arrives, and small wording changes move the date by weeks. Net 15 beats Net 30 for cash flow, 2/10 net 30 buys early payment at a known cost, and deposits or milestones protect big projects. This playbook compares the options with real numbers.
The four terms that cover almost every invoice
Nearly every invoice in the wild uses one of four term structures. None is universally best — each fits a different mix of client type, invoice size and how much of your own cash you can afford to have parked in someone else's bank account.
| Terms | Best for | Cash-flow effect | Watch out for |
|---|---|---|---|
| Net 15 | Repeat clients, retainers, smaller invoices | Cash arrives in weeks, not months; clients already on Net 30 rarely push back | First-time enterprise clients may run a fixed 30/45/60-day cycle you cannot negotiate around |
| Net 30 | The default for established B2B relationships | Predictable; matches most accounts-payable cycles | Thirty days starts whenever the client decides the clock started — see the clause below |
| Net 60 / Net 90 | Large corporates and the public sector | You are financing the client for two to three months | Price it in: slow-paying clients should pay higher rates, not lower ones |
| 2/10 net 30 | Clients with cash on hand and disorganized AP | 2% discount if paid within 10 days; full amount due by day 30 | Some clients take the discount and still pay late — enforce it or drop it |
What 2/10 net 30 actually costs you
The discount buys twenty days of acceleration: cash on day 10 instead of day 30. Giving up 2% to receive 98% twenty days early works out to roughly 37% annualized — (2/98) × (365/20). No credit line costs anywhere near that, which cuts both ways: offering the discount is an expensive way to raise cash, and taking it when a client offers it is cheap financing for them.
The useful conclusion is that the discount is a tool for a cash emergency, not a standing policy. If clients need a nudge to pay early, 1/10 net 30 buys almost the same acceleration at half the cost.
| Terms | Days gained | Cost of the discount | Annualized |
|---|---|---|---|
| 2/10 net 30 | 20 | 2.04% of the invoice (2/98) | ≈ 37% |
| 1/10 net 30 | 20 | 1.01% of the invoice (1/99) | ≈ 18% |
| 2/10 net 45 | 35 | 2.04% of the invoice | ≈ 21% |
Deposits and milestones for project work
One-off projects carry the most default risk: a client you may never work with again owes you the largest amount at the moment you have the least leverage — after the work is done. Splitting the money against progress converts that risk into a schedule.
- 40-50% deposit before work starts on anything over a week of effort. It is a commitment filter as much as cash flow: clients unwilling to fund a start are forecasting their own payment behavior.
- Milestones for projects beyond a month: 40% to start, 30% at the midpoint deliverable, 30% before handover of source files or credentials.
- Final files move only after the final payment clears — write that handover condition into the proposal, not into the argument you will otherwise have later.
- Recurring work bills in advance: on the first of the month, every month, no exceptions taken personally.
The clause that makes terms enforceable
Terms fail in disputes when they are ambiguous about two things: when the clock starts, and what lateness costs. One sentence settles both:
Payment is due within 15 days of the invoice date. Invoices unpaid after the due date accrue a late fee of 1.5% per month (18% per year) or the maximum rate allowed by law, whichever is lower, and work in progress may pause until the account is current.
The three ingredients do the work, and none of them is optional:
- Anchor the clock to the invoice date — not receipt, not approval, not the end of the client's monthly payment run.
- State the late consequence numerically, as a percentage per month, capped at the legal maximum for your state.
- Reserve the right to pause work. A fee you would never actually invoice is decoration, and experienced AP teams know which invoices carry it.
A collections timeline that stays polite
Collecting is a schedule, not a mood. Escalation works because it is boring and predictable — every step is small, documented, and exactly as firm as the number of days requires. Most late invoices are stuck in a process, not refused; the timeline is designed to find the stuck ones fast and put the refused ones on notice early.
| When | Move | Tone |
|---|---|---|
| Day 0 — invoice sent | Invoice plus a short work summary in one email; confirm the AP contact and PO number | Businesslike |
| Day 7 before due | One-line reminder with the invoice re-attached | Neutral |
| Day 1-3 past due | Polite nudge; assume process failure, not bad faith | Friendly |
| Day 10 past due | Call or message the AP contact directly; get a payment date, in writing, in the thread | Firm |
| Day 30 past due | Invoice the late fee per the clause; pause new work | Formal |

Frequently asked questions
- Is Net 30 counted from the invoice date or when the client receives it?
- Whichever your invoice says — so say the invoice date. Unstated defaults invite the client's AP department to start the clock at their monthly payment run, which can quietly add weeks. The clause above removes the ambiguity, and so does printing the PO number on the invoice itself.
- What percentage deposit is normal for freelance or agency work?
- 40-50% before starting is standard for projects in the low five figures, and few serious clients object. Below 30% you are mostly financing the project yourself; above 50%, corporate procurement may need an exception approval, which slows the signature you are waiting on anyway.
- Can I charge a late fee if the invoice never mentioned one?
- Weakly, at best. Most US states allow statutory interest on overdue commercial invoices, but the allowed rate is usually lower than a well-drafted clause, and you are negotiating the point after the relationship is already strained. The fix is preventive: every invoice carries the terms, every time.
- Do payment terms belong in the contract or just on the invoice?
- Both, with identical numbers. The contract makes the terms binding; the invoice is what the AP clerk actually reads and keys into the payment system. When the two documents disagree, most systems follow the invoice — so copy the clause onto the invoice footer verbatim.
