Zero-Based Cash Budgeting

How a zero-based exercise works

Print every recurring expense over the past 90 days. For each, write the answer to: 'If we were starting today and didn't have this, would we add it?' If the answer is no or 'maybe,' put it on the cut list. If yes, justify the level — most subscriptions, software seats, and recurring services have crept up over time without explicit approval.

Typical first-pass cuts: 15-30% of overhead in a business that's never done a zero-based exercise. Common offenders: redundant software (multiple seats per user, overlapping tools), professional services (advisors who haven't engaged actively), unused warehouse or office space, dormant marketing campaigns.

When to use it

Originally a corporate practice (Texas Instruments and the federal government in the 1970s), zero-based budgeting has been popularized in the 2010s by 3G Capital's acquisitions (Anheuser-Busch InBev, Kraft Heinz). For owner-operated businesses it's appropriate at three moments: after a major revenue drop, before a planned raise (to demonstrate cost discipline), and as an annual exercise during the budget cycle.

It's emotionally hard. Each cut feels like admitting failure. The reframe: identifying waste isn't admitting failure, it's identifying opportunity. Most businesses run a zero-based exercise once and find the discipline becomes self-reinforcing — the subscription explosion that built up over five years doesn't recur because someone is now asking the question continuously.

Running a ZBB process under stress

The compressed ZBB process for a cash crisis is two weeks: week one, every department head submits a defended budget for the next 90 days starting from zero, with each line item categorized as essential / important / nice-to-have. Week two, the leadership team reviews and cuts to the cash target, with the principle that nice-to-haves go first, importants get a 50% cut, and essentials are protected.

The hardest discipline is being honest about what's essential. Most teams categorize most things as essential when the question is asked abstractly. Tying each 'essential' line item to a specific revenue, customer, or compliance dependency forces a more rigorous answer; many supposedly essential expenses turn out to be habits the team had stopped questioning.

ZBB done in a calm year is uncomfortable but sustainable; ZBB done quarterly during a turnaround is exhausting and corrosive to morale. Use the process as a one-time reset, not a permanent operating mode. After the reset, the new baseline becomes the budget, and incremental quarterly reviews go back to normal.
