Automatically verify your project invoices
In an IT consulting firm, the final invoice results from a multi-source calculation: budget sold, days delivered, applicable discounts, amendments. Manual verification is a source of errors and disputes.
The problem
As the project portfolio grows, pre-billing verification becomes a bottleneck: reconciling the budget sold (CRM), days delivered (staffing tool), contractual discounts and any amendments to verify the invoice is correct. Undetected errors generate disputes at close or unidentified net losses.

- CFO dashboard with view by project and by client
- Alerting on projects showing gaps before invoice is sent
Observed results
- Reduced pre-billing verification time
- Proactive gap detection before sending to client
- Fewer billing disputes
Frequently asked questions
Does it work if our contracts have complex billing rules (fixed price, time and materials, variable day rate, tiered discounts)?
Yes. Calculation rules are configured during the audit. Each contractual rule is translated into reconciliation logic. Cases not covered by general rules are escalated for human validation.
Which staffing tools are compatible?
The most common tools in French IT consulting firms: Boond, Silae, Nibelis, Harvest, or Excel exports if your staffing is still on spreadsheet. We assess feasibility during the scoping call.
Does it also cover subcontractors?
Yes. The engine can integrate incoming supplier invoices and match them against purchase orders and received deliverables, in addition to outgoing client billing.
What is the cost?
This type of mission is generally billed between €30,000 and €50,000 depending on the number of sources and the complexity of contractual rules. The audit alone is available between €10,000 and €20,000.
