INVOICE PROCESSING
AI intake agent that extracts, converts, and routes emailed multi-currency invoices
Reads invoices arriving in a shared inbox, uses an AI agent to extract vendor, currency, and totals, converts to base currency.
How it runs
The automated pipeline, trigger to output.
- TriggerNew invoice email in shared inboxGmail
- ActionAI extracts vendor, currency, amount, dateOpenAI
- ActionFetch FX rate and compute base totalHTTP webhook
- LogicPick approver by vendor and converted amount
- ActionInsert normalized invoice into Postgres stagingPostgres
- OutputSend approval request to owner in SlackSlack
What it does
This agent-driven workflow handles unstructured invoices that arrive by email in any layout or currency. It extracts the key fields, normalizes the total to your reporting currency, decides the correct approval owner by vendor and amount, and stages a clean record for the ledger.
When to use it
Use it when invoices come as PDFs or inline email in inconsistent formats and currencies, and you want hands-off extraction plus FX normalization plus routing without building rigid parsers per vendor.
How it works
- 1A new email in the shared finance inbox triggers the workflow.
- 2An AI extraction step reads the message and attachment to pull vendor, currency, amount, and invoice date.
- 3An HTTP call fetches the FX rate for the invoice date and the base-currency total is computed.
- 4A logic step selects the approver based on vendor and converted amount thresholds.
- 5The normalized invoice is inserted into Postgres staging and an approval request is sent to the chosen owner in Slack.
