INVOICE PROCESSING
Block Invoice Approval When Vendor Price Drifts Beyond Limit
Receives each invoice via webhook from your AP system, checks the new amount against the contracted baseline.
How it runs
The automated pipeline, trigger to output.
- TriggerAP system posts new invoice to webhookHTTP webhook
- ActionFetch contracted baseline rate for the vendorPostgres
- LogicCompare billed amount to baseline; branch on drift limit
- ActionMark over-threshold invoices as held for reviewPostgres
- OutputSend approval request with drift detail to TeamsMicrosoft Teams
What it does
This workflow inserts a price-drift guardrail directly into your approval pipeline. When your accounts-payable tool posts an invoice to the webhook, the workflow compares the billed amount to the vendor's contracted or last-approved rate. Invoices within tolerance pass through and are marked auto-approvable. Invoices that exceed the drift limit are held and pushed to a Microsoft Teams channel where an approver must explicitly accept or reject the increase, with full before-and-after context attached.
When to use it
Use this when you have an AP system that can call a webhook and you want price increases to require a human decision rather than slipping through automated approval. Ideal for finance teams enforcing contracted rates.
How it works
- 1The AP system sends a new invoice payload to the webhook trigger.
- 2The workflow reads the contracted baseline for that vendor from Postgres.
- 3A logic step compares billed amount to baseline and computes drift.
- 4Within-tolerance invoices return an auto-approve response and the run ends.
- 5Over-threshold invoices are flagged as held.
- 6A Microsoft Teams message goes to approvers with old rate, new rate, delta, and approve or reject actions.
