INVOICE PROCESSING
Real-Time Quantity-Variance Check on Incoming Invoice Webhook
Receives invoices via webhook from your procurement system, instantly checks received-quantity against the PO and receipt.

What it does
This catches quantity mismatches the moment an invoice is submitted, rather than at a nightly batch. It compares billed quantity against what the PO authorized and what was actually received, so short-ships and phantom-quantity over-bills get flagged in seconds.
When to use it
Reach for this when your procurement platform can fire a webhook on invoice submission and you want quantity disputes raised before the invoice ages into a payment run. Best for high-volume goods purchasing where quantity drift is the common failure.
How it works
- 1The procurement system posts an invoice payload to the webhook endpoint.
- 2The PO and goods-receipt rows are looked up in Snowflake by PO number.
- 3A variance check compares billed quantity to PO quantity and received quantity per line.
- 4Exact matches are written back as approved.
- 5Any quantity variance opens a Linear issue assigned to the buyer, with the line, expected, and billed values in the body.
- 6A short confirmation posts to Slack so AP sees the dispute was raised.
