Retention / Retainage

A percentage of payment withheld from each progress payment until project completion to ensure satisfactory work.

Definition

Retention (or retainage) is the practice of withholding a portion (typically 5-10%) of each progress payment to a contractor or subcontractor. The retained amount is held until the project is substantially complete and all punch-list items are resolved. It serves as financial incentive for project completion.

Why It Matters

Retainage protects project owners from incomplete work. However, it must be tracked carefully per subcontract and released according to contract terms to maintain subcontractor relationships.

Examples

10% retainage

Sub invoices $100,000 for work completed. GC pays $90,000 and withholds $10,000 (10%) as retainage.

Retainage release

At substantial completion, the accumulated retainage of $45,000 is released after final inspection and punch-list completion.

How Aequo AP Helps

Aequo Build calculates retainage from the subcontract rate when a subcontractor invoice is approved, tracks held, released, and remaining amounts by job and vendor, requires approval for partial or full releases, and keeps a release history where a release can be reversed with a reason.
