The problem

Import invoices ran to hundreds of lines across varied supplier formats. Data entry took days per shipment and errors in cost lines propagated into pricing and margin.

What we built

We built document extraction that reads supplier invoices into structured lines, matched against the purchase order. Lines the model is unsure about are flagged for a person rather than posted silently.
