Stop Paying Twice: Spot Duplicate POs in 60 Seconds

Duplicate POs and repeat freight invoices hide inside marketplace chaos.

Our benchmarks show 5-15 % margin loss—enough to erase whole product lines.

The 2-Blank Test

  • Grab last month’s PO count.
  • Grab the average $ value per PO.
  • Paste both into the Spend-Leak Calculator.

In one click you’ll see exactly how much you’re paying twice—right now.


Why Operators Miss It

Multiple ordering portals, freight invoices arriving days later, and “urgent re-orders” that slip past approval flows.

  1. Surface the leak with the calculator; save the screenshot.
  2. Tag the fast movers—most duplicates trace back to them.
  3. Centralise PO creation in one dashboard to stop double freight at the source.
  4. Set alerts for duplicate lines or freight > $X—watch the leak close in one billing cycle.

Run the calculator → screenshot your leak → email sales@mainstem.io for a free benchmark.
