TAIL SOURCING
Free tail spend diagnostic

Master the tail spend The End-to-End platform built for the 20–40% of spend that legacy suites never touch.

While the giants fight over your strategic spend, we specialize in the rest — fragmented vendors, one-off purchases and indirect categories. That's where margin hides, and where our AI makes the difference.

The problem

The problem everyone faces (and no one solves)

Tail spend silently drains 20–40% of indirect budgets. Most teams don't even know where to start.

Off-policy spend

Up to 40% of purchases happen outside approved channels — and finance only finds out at month-end.

Zero visibility

You can't optimize what you can't see. Tail spend hides across hundreds of vendors and dozens of cost centers.

Manual processes

Emails, spreadsheets and PDFs slow approvals and quietly burn thousands of hours per year.

Fragmented vendors

Hundreds of one-off suppliers, no consolidation, no leverage, no negotiated savings.

For small businesses and mid-sized teams

If your team still approves purchases over emails, PDFs and spreadsheets, you're already losing money — small businesses and mid-sized companies are exactly who we built Tail Sourcing for.

Our wedge

Tail spend isn't "the rest". It's the opportunity.

Big procurement suites were built for the 20% of spend already under control: master contracts, direct categories, strategic suppliers. The other 80% — one-off vendors, urgent buys, indirect categories — lives in spreadsheets and email. That's where margin bleeds, and that's where Tail Sourcing was built from day one.

  • Designed for hundreds of fragmented suppliers, not 20 global accounts.
  • AI that reads the messy inputs — invoices, screenshots, quotes — and turns them into structured records your team reviews.
  • Deployed in weeks, not years. No seven-figure consulting bills.
