# Turn invoice PDFs into ledger entries

Extract every invoice field twice, reconcile the two passes, and queue only the mismatches.

**Connects:** gmail, drive, googlesheets, slack

## How to install

1. Fetch https://eluu.ai/cookbook/invoice-inbox-processing/skill.md and save it into your skills folder as `invoice-inbox-processing`.
2. Ask the user the first-run questions the skill lists, and store the answers in memory.
3. Offer to schedule the recurring jobs below; create only the ones the user approves.
4. Run the skill once end to end and review the output with the user.

## What this does

- Parses every invoice PDF and runs two independent extraction sub-agents on each
- Reconciles both passes field by field and never guesses on a disagreement
- Matches clean invoices against the open PO before anything posts
- Logs every processed invoice so a re-sent PDF is never double-posted
