Flag Vendor Price Increases
Every morning, WebRun reads new supplier invoices from Gmail, compares each line-item price against the last approved rate in QuickBooks, and sends you an alert in Slack for any item where the price has jumped.
How can I automatically detect when a vendor raises their prices?
Every morning, WebRun reads new supplier invoices from Gmail, compares each line-item price against the last approved rate stored in QuickBooks, and sends you a Slack alert for any item where the price has increased - so you can challenge or approve the change before payment goes out.
- Price increases caught before payment is approved
- Every invoice compared against your agreed rates automatically
- No surprise cost increases buried in invoice line items

Questions, answered
Will it approve or reject invoices automatically?
No - it only flags price increases. All invoice approval decisions stay with you in QuickBooks.
What counts as a price increase worth flagging?
You set the variance threshold (default 5%). Anything below that is logged but not alerted, keeping your Slack signal-to-noise ratio clean.
What if a supplier updated their prices legitimately?
Once you approve the new rate and pay the bill, QuickBooks has the updated baseline - future invoices at that rate won't trigger an alert.
