Payment terms determine when you get paid, how you get paid, and what happens when payment is late. Vague terms like "upon approval" or extended timelines like Net 90 can quietly destroy your cash flow. Here's how to read payment terms and negotiate ones that actually protect you.

Payment terms specify when, how, and under what conditions you'll be paid for your work. They include the payment timeline (Net 30, Net 60, etc.), the trigger for payment (invoice date, delivery, approval), any upfront deposits, milestone schedules, and late payment penalties.
"Net 30" means payment is due 30 calendar days after the invoice date. "Net 60" means 60 days. Some enterprise contracts push to Net 90 or even Net 120 — meaning you could deliver work in January and not get paid until May.
Payment terms are found in freelance contracts, vendor agreements, consulting engagements, and service agreements. They're often buried deep in the contract and written in language designed to give the paying party maximum flexibility — and the worker minimum certainty.
Payment "upon client approval" with no deadline
If payment is contingent on the client approving the work, but there's no deadline for that approval, the client can delay payment indefinitely by simply not reviewing your deliverables. This is one of the most common payment traps in freelance contracts. Without a defined approval window, "upon approval" effectively means "whenever we feel like it."
Net 90 or longer payment terms
Net 90 means you're financing the client's project for three months out of your own pocket. For freelancers and small businesses without deep cash reserves, this can be devastating. Large corporations use extended payment terms as a form of interest-free financing at your expense.
No late payment penalty
If the contract has no consequence for late payment, there's no incentive for the client to pay on time. Without a late fee clause, your only recourse for chronic late payment is to threaten legal action — which is expensive and damages the relationship. A late fee clause creates automatic accountability.
Payment only after "final deliverable" with unlimited revisions
If you only get paid when the "final deliverable" is accepted, and the contract allows unlimited revisions, the client can keep requesting changes forever — and you keep working for free until they decide it's done. This is scope creep weaponized through payment terms.
Actual clause from a real contract
"Payment shall be made within ninety (90) days following Client's written acceptance of the final Deliverables. Client may request reasonable revisions to ensure the Deliverables meet the project specifications. Contractor acknowledges that payment is contingent upon Client's satisfaction with the completed work."
This clause is problematic because it chains three delays together: first, the client must give "written acceptance" (no deadline specified). Second, the client can request "reasonable revisions" (undefined and unlimited). Third, payment is contingent on "satisfaction" (subjective and unverifiable). Even after acceptance, you still wait 90 days. A project delivered in January might not get paid until June — or never, if the client keeps requesting "reasonable" changes.
Suggested counter-language
"Payment terms: Net 14 from invoice date, or Net 30 at most. Deliverables are deemed accepted if Client does not provide written feedback within 5 business days of delivery. A late fee of 1.5% per month applies to overdue balances. For projects exceeding $5,000, a 50% non-refundable deposit is due before work begins. Revisions are limited to two rounds included in the project fee; additional revisions billed at the hourly rate."
Key negotiation points:
Cash flow is the number one reason freelancers and small businesses fail. It's not that they don't earn enough — it's that the money comes too late. A freelancer with $20,000 in outstanding invoices on Net 60 terms is technically doing well, but if rent is due next week, those invoices are worthless.
Large companies know this. Extended payment terms are a deliberate financial strategy that shifts the cost of capital from the buyer to the seller. When a Fortune 500 company pays you Net 90, they're earning interest on your money for three months while you scramble to make payroll.
The best time to negotiate payment terms is before you sign. Once work is underway, you have far less leverage. And once work is delivered, you have almost none. Get the terms right upfront, in writing, before a single deliverable changes hands.
