Dropbox invoice scan to Postgres ledger with duplicate guard
Extracts vendor, invoice number, and totals from scanned invoices dropped in Dropbox.

What it does
Scanned invoices placed in a Dropbox folder are parsed for vendor name, invoice number, date, and total amount, then written into a Postgres accounting ledger — but only if that invoice number is not already on file, preventing double entry.
When to use it
Use it when vendors email or hand over paper invoices that someone scans into Dropbox, and you want them landing in your database ledger automatically without paying twice for the same invoice number.
How it works
- 1A new scanned invoice in the Dropbox folder triggers the run.
- 2The file is downloaded from Dropbox.
- 3A Hugging Face document model extracts vendor, invoice number, issue date, and total.
- 4A logic step queries Postgres for the extracted invoice number scoped to that vendor.
- 5If a matching row already exists, the run stops and logs a duplicate so nothing is inserted twice.
- 6If it is new, the invoice is inserted into the Postgres ledger table with all extracted fields and the source file link.

- 2Connect Hugging FaceModels, datasets, spaces — the open-source hub.
- 3Connect PostgresAny Postgres URL — query, write, migrate.
- 4Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
- 5Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
- 6Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
