Back-office AI where the law dictates the process
The Japanese context matters here: electronic bookkeeping rules and the qualified invoice system define the shape of the process.

Why it survives
Storage format, search requirements, approval records, qualified invoice rules. Generic OCR plus a workflow tool does not satisfy them, so people keep reading documents and typing numbers.
Where AI applies
| Step | Before | With AI |
|---|---|---|
| Reading receipts | Manual entry | Extraction plus account code suggestion |
| Invoice matching | Manual reconciliation | Automatic, humans see only exceptions |
| Approval routing | Consult a rules table | Inferred from content |
| Journal entries | Operator judgement | Candidates from history |
Why not build it yourself
You can combine OCR with a workflow engine. You then own the search capability that satisfies the retention rules, the tamper-evidence mechanism, and every change when the tax rules move. In a domain where the requirements change regularly, outsourcing compliance is worth more than build flexibility.
How to evaluate
Count how many existing tools it removes, not the monthly figure alone. Then measure the close: five working days becoming three is a decision-speed result, not a headcount one.
FAQ
Does this work for a small company?
It depends on volume. Below a few hundred documents a month, the migration effort exceeds the saving.
