Payment Terms That Get You Paid: Deposits, Net Terms, and Late Fees for Agencies
TL;DR — Get paid faster by deciding it upfront, not by chasing harder later. Take a 30–50% deposit before work starts, bill the rest at milestones, default to Net 15 (not Net 30) for new and smaller clients, put a clear late-fee clause (commonly 1–2% per month) on every invoice and contract, and always include a direct payment link. Good terms turn collection from a monthly fight into a formality.
Most agencies treat payment terms as boilerplate copied from the last proposal. But terms are the single biggest lever you control before an invoice is ever late. By the time you’re chasing, your options are limited to firmer emails. The terms you set decide how often you have to send those emails at all.
Why payment terms matter more than your follow-ups
You can have the best chase emails in the world and still wait 60 days for cash, because terms set the starting line. Net 30 means the clock can’t possibly run faster than 30 days — and in practice it runs longer, since the global average from invoice to payment is around 39 days. Net 15 with a deposit means much of your money is already in the bank before the project even ends.
Strong terms do three things at once: they shorten the gap between work and cash, they shrink the amount you’re ever exposed to on a single client, and they give every later follow-up a clear contractual basis. Weak terms quietly cap how good your collections can ever get.
How big should a deposit be?
For most agency work, 30–50% upfront is standard and reasonable. A deposit does more than fund the start of the project:
- It removes that money from your receivables entirely — it can never be late, which directly lowers your Days Sales Outstanding.
- It filters out clients who were never going to pay. A client who balks at any deposit is showing you something useful before you’ve done the work.
- It changes the psychology. A client who has paid something is far more likely to pay the balance promptly.
For larger or longer projects, split the balance into milestone payments rather than one lump at the end. Money collected at each milestone is money you never have to chase.
What net terms should you offer?
| Term | Best for | Effect |
|---|---|---|
| Due on receipt / Net 7 | Small projects, one-off work, new clients | Fastest cash, minimal exposure |
| Net 15 | Most agency retainers and mid-size projects | A sensible default — faster than the Net 30 norm |
| Net 30 | Established clients who require it; larger firms | Standard, but plan cash flow around the real ~40-day reality |
| Net 60 / Net 90 | Big enterprise clients with rigid AP cycles | Only if the margin and relationship justify financing them |
The mistake is defaulting to Net 30 for everyone out of habit. Set the shortest term the relationship can bear — you can always be more generous with a trusted long-term client, but it’s hard to walk terms back once they’re the norm.
Should you charge late fees?
Yes — if they’re agreed in advance. A late fee of 1–2% per month on the overdue balance is a common, defensible rate. The fee matters less as a revenue source and more as a signal that your terms are real.
Three rules make late fees work instead of backfire:
- Put it in the contract and on every invoice. “A late fee of 1.5% per month applies to balances past their due date.” No surprises.
- State it before it bites. Reference it in your day-30 follow-up so the client can act before it’s charged.
- Apply it consistently. A fee you threaten but never enforce teaches clients your terms are optional — the opposite of the point.
Putting terms into practice
- Write terms into the proposal, not just the invoice. Agreement happens at signing, not at billing.
- State the due date as a date, not a duration. “Due 30 June” is harder to misread than “Net 15.”
- Always include a payment link so acting on the invoice takes one click. See how to wire one up in Zoho Books + Razorpay.
- Make the terms enforceable without drama by pairing them with a consistent escalation ladder — the terms define what’s owed; the ladder collects it.
Even perfect terms still need someone to send the reminders, apply the fees, and track who’s paid. Automating that is what an AI accounts receivable clerk like Zira handles, so your terms actually get enforced every time.
FAQ
What are the most common payment terms for agencies?
Net 15 and Net 30, usually paired with a 30–50% upfront deposit. Smaller and newer clients should sit at the shorter end; only offer Net 60+ when a large client’s process requires it and the margin justifies financing them that long.
Can I change payment terms with an existing client?
Yes, but do it openly and going forward, not retroactively. Frame it around a new project or contract renewal: “For new work starting this quarter, we’re moving to a 40% deposit and Net 15.” Most reasonable clients accept clear, consistent terms.
Are late fees legally enforceable?
Generally yes when they’re stated in a signed agreement and the rate is reasonable, though specifics vary by jurisdiction and contract. The practical value of a late fee is usually as a deterrent and a clear escalation step rather than something you litigate over.
What’s the single fastest way to reduce late payments?
Take a deposit. Upfront money never enters your receivables, can’t be paid late, and signals a serious client — it’s the highest-leverage change most agencies can make to their terms.
