How long does implementation take?
3 to 5 weeks, depending on the number of document formats. Building it is usually the shorter half - the time goes into access, coordination and test cases.
What do we have to provide?
A mailbox or folder where the documents arrive - email, scan, portal. Read access to orders and delivery notes; without them there is nothing to check against. The posting logic in writing, once: which cost centre applies when. Nothing more is needed to start.
How will we know it works?
From verifiable criteria agreed before the build: Across 200 real documents, supplier, purchase order and cost centre are matched correctly in at least 95 %. Every discrepancy between invoice and order ends up in the clarification loop, not in the ledger. No posting without a reference to the document it came from.
Does the AI decide on its own?
The unambiguous part runs through. Anything with a discrepancy, a missing order or an unusual amount goes to a person - together with the reason why.
When is this not worth it?
With very small document volumes the effort does not pay. Below roughly 300 documents a month the saving is smaller than the upkeep.
Which sectors does this suit?
In our experience particularly Wholesale, Logistics, Tax advisory, Trades. The process itself is sector-independent, though - what matters is whether it repeats.
