PO Processor Flagged $47K Order for CFO Approval Before Procurement Opened Email (6 Nodes) 🔥
$47,000 purchase order arrived Friday afternoon. CFO notification hit Slack in 3 seconds. Approval happened before weekend.
Built PO processor. Approval tier routing. Urgency detection. Right people see right orders immediately.
THE PURCHASE ORDER CHAOS:
PO arrives by email. Someone downloads. Someone reviews. Someone determines approval level. Someone routes to correct person.
Four steps. Four delays. Large orders sometimes go to wrong approval level.
THE DISCOVERY:
Document extraction pulls vendor, line items, totals. Code calculates approval tier and urgency. Routing happens automatically.
No more guessing who should approve. Thresholds decide.
THE WORKFLOW:
Gmail trigger catches PO attachments → Get message downloads document → Document extraction pulls vendor details, line items with quantities and prices, totals → Code calculates approval tier and urgency level → Sheets logs with tracking ID → Slack notifies correct approver with breakdown.
6 nodes. Procurement bottleneck eliminated.
THE APPROVAL THRESHOLDS:
Amount determines who approves:
- Under $1K: Auto-approve
- $1K-$5K: Manager
- $5K-$25K: Director
- Over $25K: VP/CFO
No exceptions. No confusion. Thresholds enforced.
THE URGENCY CALCULATION:
Delivery date determines urgency:
- 3 days or less: Urgent (red flag)
- 7 days or less: High priority
- Over 7 days: Normal
Rush orders get flagged. Nobody discovers urgency too late.
THE TRANSFORMATION:
Before: 29 minutes per PO for processing and routing. Large POs sometimes routed incorrectly. Urgent orders discovered late.
After: Instant routing. Correct tier every time. Urgency visible immediately.
THE NUMBERS:
243 POs processed last quarter
$47K flagged for CFO automatically
12 urgent orders caught early
29 minutes → 3 seconds per order
