Subcontractor pay applications often separate current work, approved change orders, stored materials, retainage, and previous payments. Retainage can be misstated when a revised rate or partial release is applied without a project-level rollforward.
The goal is not to force every number to zero. It is to explain each movement using the records the business is authorized to use, distinguish timing from a real discrepancy, and put decisions in front of the right reviewer. That makes the work suitable for offshore bookkeeping support: the preparer handles repeatable evidence work while the company retains authority.
Useful background for designing the procedure includes FAR retainage guidance and AIA payment application overview. These sources do not replace the company’s contracts, accounting policy, or professional advice. Record the version and access date when a changing rule or provider document affects the workflow.
