The 2026 Reality Check
Zero-based budgeting (ZBB) got a reputation for being grueling. In an AI-first world, that's changing — the marathon of justifying every line item can now be accelerated with tools that pull spend history and benchmark costs automatically.
Where ZBB Actually Pays Off
- Discretionary spend categories (travel, software, agencies)
- Companies over $50M revenue with bloated G&A
- Post-acquisition cost rationalization
Where It Doesn't
Beware of applying ZBB to every cost center in year one. Pick two or three categories, prove the ROI, then expand.
The Pilot Playbook
- Pick one category with clear benchmark data
- Use AI to draft a zero-base build-up from spend history
- Let owners defend, adjust, and sign off
- Compare savings against the effort — and scale only if the ratio works
Done well, ZBB isn't about cutting — it's about re-justifying spend in light of current strategy.
