Accounts payable is usually the right first target: high volume, clear rules, measurable cycle time and an obvious system of record.
Finance teams rarely lack candidates for automation. The difficulty is choosing the one that will prove the case rather than consume the year.
The best first process has four properties: it repeats often, its rules can be written down, its cycle time is already measured, and it ends in a system that can be posted to programmatically.
Why accounts payable qualifies
Invoice handling repeats hundreds of times a month, the matching rules are explicit, delays are visible, and the ERP provides a clean destination for the result.
It also contains a natural split between the work a rule can do and the work a person should do — which is where intelligent automation earns its keep.
Sequence the build
Capture and extraction first, because they remove the re-keying. Validation and purchase order matching next, because they remove the checking. Approval routing after that, because it removes the chasing. Posting and archiving last, because they close the loop.
Each stage is independently useful, which means the programme returns value before it is finished.
Keep the exceptions visible
The goal is not to automate every invoice. It is to automate the ordinary ones completely and route the unusual ones to the right person with the context already attached.
