Across 12+ stack rationalisation engagements, we typically find 15-25% vestigial spend + another 15-25% consolidation/rebuild upside. Fourteen probing questions on stack composition, active-seat ratios, recent M&A, layoffs, top spend categories. Output: vestigial-spend estimate, consolidation candidates, top rebuild targets. The 8-page memo includes the cancellation playbook + renewal-negotiation timing.
Vestigial spend estimate uses our 12-engagement bench data — typical waste ranges 15-25% of total SaaS spend. Adjustments: M&A inflates duplication, layoffs inflate ghost seats, low active-ratio inflates waste. Consolidation candidates derived from category-overlap heuristics (e.g., 3+ "support" tools usually indicates consolidation opportunity). Rebuild candidates flagged when category spend exceeds rebuild-payback threshold (typically $200K+/yr per tool).
Tools signed for a project that ended, used by a team that left, or duplicating capability already available elsewhere. Typically 15-25% of total spend across our 12+ engagements.
30-50% total SaaS spend reduction within 12-18 months, combining cancellations + consolidation + selective rebuild. Documented in 6 of our case studies.
