Kansas retainage and prompt pay

Kansas public work is the 5% planning cap, with retainage typically due about 60 days after acceptance. Prompt-pay on public jobs is relatively subcontractor-friendly: owner-to-prime is often 30 days after invoice, and prime-to-sub is 7 days after the prime is paid (Kan. Stat. § 75-6909 alongside the Fairness in Private Construction Contract Act in § 16-1803).

Private retainage still follows the subcontract. Do not copy a Kansas public 5% model onto a private warehouse job unless the contract actually says 5%. The statute fight on private work is more often payment timing than a retainage ceiling.

If you are billing Kansas this month, set the calculator to the contract rate, then use the G702-style sheet so Line 7 matches last month’s certificate — Kansas GCs still reject pay apps for that mismatch.

Statute text: Kan. Stat. § 16-1803. Confirm the current code before you rely on a date.
