The Purchase Order Processing Challenge

Purchase order (PO) processing is a critical business function that connects procurement, receiving, and accounts payable. Yet many Indian businesses still manage POs manually, leading to:

  • Lost purchase orders — Paper POs get misplaced
  • Delayed matching — Manual 3-way matching takes days
  • Invoice fraud — Without proper PO matching, unauthorized invoices slip through
  • Cash flow issues — Poor PO visibility leads to budget overruns

What Is PO Processing Automation?

PO processing automation digitizes and streamlines the entire purchase-to-pay cycle:

1. PO Creation

Create standardized digital purchase orders with:
  • Vendor details and terms
  • Line items with quantities and rates
  • Approval routing based on amount
  • Budget checks against department allocations

2. PO Matching with Invoices

When invoices arrive, AI automatically:
  • Identifies the corresponding PO number
  • Matches line items between PO and invoice
  • Flags quantity or rate discrepancies
  • Handles partial deliveries and back orders

3. Three-Way Matching

Automated comparison of:
  • Purchase Order — What was ordered
  • Goods Receipt Note (GRN) — What was received
  • Invoice — What is being billed
Discrepancies are flagged for review while matching invoices are auto-approved for payment.

4. Payment Processing

Once matched and approved:
  • Payment due dates are tracked automatically
  • Early payment discounts are highlighted
  • Payment batches are created for bank processing

Where TaskAutomate Fits Today

TaskAutomate doesn't link invoices to purchase orders or match them yet. It handles the invoice side:

  • Extracts vendor, line items, quantities, unit prices, tax and totals
  • Checks GSTINs and the CGST/SGST/IGST split
  • Requires approval above an amount threshold you set
  • Posts approved invoices to Tally, or exports them to CSV and Excel for PO matching in your ERP
