The numbers behind the calculator
We benchmark your current tooling against a unified-platform ceiling — the savings rate a best-in-class tail spend program consistently achieves.
Email + spreadsheets
Average savings captured on tail spend when buying happens over email, with manual approvals and no central catalog.
Basic P2P tool
Better visibility, but tail categories still fall outside guided buying. Most savings depend on negotiation cycles.
Unified platform
AI-assisted RFx, pre-negotiated catalogs and guided buying capture the long tail by default — our ceiling.
Baselines are blended estimates derived from Hackett, APQC and Spend Matters benchmarks for tail spend categories. Actual results vary by industry, geography and category mix.
Tail spend is 80% of your transactions and 20% of your spend — but it's where most leakage hides.
