We rely on several subcontractors to deliver our services, and manually auditing their invoices against our project milestones and contracts is a massive administrative headache. How do we use AI to prevent billing leakage and ensure compliance?

If you are manually verifying subcontractor invoices against deliverables, you are likely losing money to billing leakage, overcharges, or non-compliant work. You can automate this audit process using AI to protect your margins.

Start by uploading your subcontractor agreements and scope templates to a secure, private AI system. Define the specific rules, milestones, and billing rates that have been pre-approved for each project.

When a subcontractor submits an invoice, have an automated system route the document to your AI tool. The AI instantly extracts the line items and compares them against your project management software to verify that the claimed milestones have actually been completed and approved by the project manager.

The AI also audits the invoice against the subcontractor agreement to ensure the billing rates align with the contracted terms. Any discrepancies, overcharges, or missing documentation are automatically flagged for review.

The invoice is only passed to your finance team for payment once it passes this automated audit. If an issue is flagged, the system drafts a polite email to the subcontractor pointing out the specific discrepancies that need to be resolved.

This system protects your cash flow without requiring your managers to spend hours cross-referencing spreadsheets and contracts.
