A Gulf telecom operator's finance function - Multimodal invoice validation

المشكلة

AP teams were manually comparing supplier PDFs, iSupplier entries, and Oracle ERP records. Three-way matching is the kind of work that is too rule-bound to be interesting and too variable to script: the same supplier's invoice arrives in a different layout each quarter, and the discrepancies that matter are small ones buried among formatting differences that do not. Because the check was manual it was also quietly sampled under load - which is exactly when errors are most likely.

ما بنيناه

We used Gemini vision and Vertex AI to extract invoice fields, reconcile all three sources, flag mismatches, and support correction notifications back to the supplier.

ما توقّف عليه

Closing the loop back to the supplier is what stopped the same mismatch recurring every month - detection alone would have relocated the work rather than removed it. Relevant to finance operations whose control is technically three-way matching and practically a sample.
