Prepare invoice data in an accounting tool
Create a reviewable draft from a validated document without silently posting it.
Before the first run
- A validated source invoice and approved field mapping
- An authorized destination account
- A duplicate-detection key and a reviewer
Define what the agent can do.
Draft preparation is distinct from posting, payment, supplier creation, or changing bank details.
The implementation sequence
- 01
Validate source fields
Check required invoice identifier, supplier identity, amount, currency, and relevant dates. Mark missing or ambiguous fields for review rather than inferring them from a similar invoice.
- 02
Find the destination supplier
Match by an approved stable identifier. If the destination has multiple candidates, stop before creating a new supplier or choosing one by name similarity.
- 03
Prepare the draft
Use a supported import where possible. If interface entry is required, fill only the approved mapping and keep the original document attached to the draft review packet.
- 04
Show the diff
Present source values, proposed destination values, and any existing draft with the same key. Highlight changed dates, currencies, and signs.
- 05
Commit and read back
After authorization for the exact operation, perform the permitted save or submission once and verify the resulting record identifier. Resolve uncertain completion before retrying.
Stop for human approval
The reviewer approves the exact mapped payload and attachment before a consequential write. If entry autosaves sensitive fields, authorization is needed before typing them.
