INVOICE PROCESSING
Detect Duplicate Billings Across Vendor Statements
On a schedule, scans incoming vendor statement line items against recorded invoices in Postgres to find charges billed more than once.
How it runs
The automated pipeline, trigger to output.
- TriggerStatement intake schedule fires
- ActionLoad vendor statement line items
- ActionQuery recorded invoices and payment statusPostgres
- LogicFlag duplicate and re-billed charges
- LogicFilter to suspected duplicates only
- OutputOpen a Linear issue per duplicateLinear
What it does
Focuses on one specific failure mode: the same charge appearing twice. It compares statement line items against recorded invoices and against each other to detect duplicate invoice numbers, repeated identical amounts on the same date, and re-billing of invoices already marked paid, so duplicates are caught before money goes out.
When to use it
When a vendor's statements occasionally re-list charges that were already invoiced or paid, and you want a hard gate that surfaces suspected duplicates as tracked work items rather than a digest someone might skim past.
How it works
- 1A schedule fires on the statement intake cadence.
- 2Statement line items for the period are loaded.
- 3Postgres is queried for recorded invoices and their payment status.
- 4A detection step flags duplicate invoice numbers, same-amount/same-date repeats, and re-billings of already-paid invoices.
- 5A filter keeps only suspected duplicates.
- 6A Linear issue is opened per duplicate with the matching evidence so AP can hold the charge and resolve it.

More Invoice Processing workflows
Catch duplicate invoices as they hit your AP inbox
Watches your accounts-payable Gmail inbox for incoming invoice emails, fingerprints each one, and routes likely duplicates to a review label instead of into the approval queue.
Gate invoice approvals on a duplicate cross-check
When an approver clicks Approve in your AP system, a webhook re-validates the invoice against paid history in Postgres and Stripe charges.
Nightly audit that flags duplicate payments already made
Runs every night to scan the last 90 days of Stripe payments against your Postgres invoice ledger.
Block duplicate Stripe payouts before they send
When a new vendor invoice is queued for payment in Stripe, cross-check it against your paid-invoice history in Postgres and halt any payout that matches an already-paid invoice.
Agent that codes Front invoices to GL accounts and drafts a bill
An agent reads each Front vendor invoice, assigns GL account codes per line item using your chart of accounts and past coding history.
Detect duplicate Front invoices and archive originals to S3
Parses each Front vendor invoice, checks it against a history table for duplicates, archives the source PDF to S3 with a normalized key, and alerts AP when a duplicate is caught.
