INVOICE PROCESSING
Block duplicate or over-billed vendor invoices at the intake webhook
Receives every invoice at an HTTP webhook before AP routing, checks Airtable for an already-paid invoice number and the vendor's contracted rate.
How it runs
The automated pipeline, trigger to output.
- TriggerInvoice submitted to intake webhookHTTP webhook
- ActionLook up invoice number and contract rate in AirtableAirtable
- LogicBranch on duplicate, over-contract, or clean
- ActionMark clean invoices Cleared-to-routeAirtable
- OutputPost blocking alert to AP Slack channelSlack
What it does
Acts as a gate at the front of your AP pipeline. As soon as an invoice is submitted it checks two failure modes at once: has this invoice number already been paid, and does the amount exceed the rate you agreed to with the vendor. Either condition halts the invoice and asks a human to clear it.
When to use it
Use this when your biggest AP leakage is duplicate submissions and creep above contracted rates, especially with recurring vendors on fixed retainers or per-unit pricing. Drop it in front of an existing approval workflow as a safety check.
How it works
- 1An invoice is POSTed to the intake HTTP webhook.
- 2The flow looks up the invoice number and vendor contract rate in Airtable.
- 3A logic step branches: duplicate number, amount over contract, or clean.
- 4Clean invoices are marked Cleared-to-route in Airtable.
- 5Duplicates and over-billings post a blocking alert to the AP Slack channel naming the reason, prior payment, and contracted amount.
