Pay-when-paid and pay-if-paid
Some contracts tie your payment to money the client receives from somebody else, which is especially common in construction and can also appear in subcontracting arrangements.
A pay-when-paid clause generally addresses the timing of payment. A pay-if-paid clause may go further by making the client's receipt of payment from a third party a condition of your right to be paid. If that upstream payment never arrives, a pay-if-paid clause may leave you unpaid.
How these clauses are treated depends on the contract, governing law, and industry. Construction contracts in particular may be subject to state-specific restrictions, but those protections do not necessarily apply to ordinary service agreements.
Ask for a fixed backstop date, so payment becomes due a set number of days after the invoice, regardless of whether the client has been paid by a third party.
Net 30 From When?
Most terms run from the invoice date, but some run from the date the client approves the work, and pairing that second version with an approval clause that has no deadline turns Net 30 into Net whenever.
Check which of these your terms are tied to:
Invoice date, the best outcome for you
Delivery date, which is fine
Approval date, safe only alongside a deemed-acceptance window
The client's receipt of payment from a third party, which is the pay-if-paid problem above
California's Freelance Worker Protection Act, effective January 1, 2025, generally covers specified professional services worth at least $250 in one contract or in aggregate with the same client over the preceding 120 days. New York's Freelance Isn't Free Act took effect statewide on August 28, 2024, applies at $800 or more, including qualifying contracts aggregated over 120 days, and allows freelance workers to file complaints with the Attorney General or bring a private civil action. Illinois's Freelance Worker Protection Act applies to work worth at least $500 over a 120-day period and has been effective for covered contracts since July 1, 2024. Los Angeles and Seattle also maintain local protections for covered freelance or independent-contractor work.
Canceled halfway, paid for nothing
Almost every service agreement lets the client end the deal early, which is normal and reasonable on its own, but you should read the sentence immediately after it. A termination clause drafted in the client’s favor may leave you disputing payment for partially completed work, reserved capacity, or non-cancelable costs.
Ask for payment covering all work performed, including partially completed work, through the termination date, plus any committed costs you can't recover.
