What is retainage?

Retainage: A percentage of each invoice the customer holds back until final acceptance.

How it works

Typical on capital equipment builds and construction-adjacent manufacturing—often 5–10% held for 30–180 days after delivery. Factors usually do not advance against retainage; you finance it separately or wait for release.
