What the audit checks
Front-Loading Detection
Identifies when early line items are claimed higher than project completion supports — protecting against contractors who pad the first few pay apps and slow down later.
Retainage Math Verification
Calculates correct retainage withheld per line item and flags any line where the math doesn't match the contract percentage.
Stored Materials Analysis
Flags large stored materials claims that lack documentation or arrive earlier than the construction schedule supports.
Schedule Reality Check
Cross-references claimed completion percentages against the pay app number and contract sum to catch unrealistic progress claims.
Math Error Verification
Verifies that (Scheduled Value × % Complete) + Stored Materials − Previously Billed = This Period amount for every line.
Double Billing Detection
Identifies line items whose scopes overlap — catching change order work that's also included in the base contract line items.
