Pro Tips for Subcontractor Retainage

  1. Retainage percentage and release conditions should be clearly specified in the subcontract agreement, including when it's paid out (typically at substantial completion or project closeout).
  2. Track cumulative retainage held across payment applications, since it can represent a significant amount by project end that affects subcontractor cash flow.

Common Subcontractor Retainage Mistakes to Avoid

  • Not tracking cumulative retainage held across multiple payment applications, which can add up to a substantial amount subcontractors need to plan cash flow around.
