Construction retainage
Retainage should move with the invoice, not beside it.
Nexus calculates subcontract retainage inside the approval transaction and links the hold to its source invoice for safe release and reversal.

Operational proof
One transaction from approval to held balance.
Subcontract-specific percentages
Approval-time calculation
Invoice-linked source key
Release protection before rejection
Read the contract rate
Nexus finds the active subcontract for the job and supplier and uses its retention percentage unless an explicit reviewed amount is present.
Calculate on approval
The held amount and net payable are recorded in the same database transaction as the approval decision.
Track by source
A stable invoice source key prevents duplicate holds when an approval is retried.
Protect releases
An invoice cannot be rejected after retainage has been released until that release is reversed.
The operating model
Held money and approval history stay in agreement.
Teams can trace the retained balance to the invoice and subcontract terms that created it, then apply controlled release schedules as the job progresses.
