Turnover & closeout
Retainage
Also called: retention
Retainage is the percentage of each progress payment the owner holds back rather than pays out, released once the work is complete and accepted. It gives the owner leverage to see the project finished and the punch list closed, and contractors typically pass a matching hold down to their subcontractors. How much is held, when a portion releases at substantial completion, and what triggers final release are all set by the contract, and some jurisdictions regulate the terms.
Why it matters
Retainage is the money that keeps the last, least glamorous work moving — the punch items, the closeout paperwork, the final inspections. It is a real cash-flow cost to contractors and subs, which is exactly why closing out cleanly and fast is worth the effort: the faster the work is proven complete and accepted, the faster the held funds release.
How it shows up on site
A portion often releases at substantial completion, with the balance held until the punch list is closed and the closeout package is accepted. Being able to show punch items closed with photos, final inspections passed, and the closeout documentation in order is what shortens the gap between finishing and getting paid.
Common mistakes
Assuming final retainage releases on its own once work looks done. Release follows acceptance of the completed work and the closeout documentation, per the contract — and the exact terms, including any statutory limits, are the agreement's and the jurisdiction's call, not a rule of thumb.

Knowing the term is step one. Proving it is the job.
