Invoice fraud detection for construction & subcontractors
Subcontractor invoicing against retention, staged payment certificates, and shifting purchase orders creates exactly the conditions duplicate and over-limit invoices thrive in — falsified or duplicated payment applications are one of the most common fraud schemes in construction. Invogi checks every invoice against your PO before it's paid.
What we catch
Subcontractor duplicate submissions
A staged or retention invoice resubmitted with a slightly different number or amount.
PO overage
Price, quantity, or total variance against the purchase order for that phase of work — see PO tolerance checks.
Bank-detail changes mid-project
A subcontractor's payment details changed partway through a long engagement — flagged before payment.
FAQ
Common questions
How common is invoice fraud in construction?
Falsified or duplicated payment applications and invoices are consistently cited as the most common construction fraud scheme — the same staged or retention invoice resubmitted with a small change is easy to miss without a systematic check.
Can Invogi check subcontractor invoices against a PO?
Yes — PO tolerance checks compare price, quantity, and total variance against the purchase order for that phase of work, catching overage before payment.
Does Invogi replace our construction accounting software?
No. Invogi is a pre-payment control layer that sits in front of your existing ERP or accounting system — it doesn't replace it or require a workflow migration.
