Zero-based budgeting (ZBB) asks a simple question: If we were starting from scratch, would we still spend on this? Instead of rolling last year's number forward, you build each expense line from zero.

When ZBB Makes Sense

Business undergoing significant change, margins under pressure, significant cost base (more than 50% of revenue), suspicion of accumulated waste, or new leadership wanting fresh perspective.

Practical Implementation

Step 1 involves listing all expense categories grouped by People, Premises, Technology, Marketing, Operations, Admin, and Other.

Step 2 involves questioning each line: What purpose does this serve? What happens if we eliminate it? Is there a cheaper alternative? What is the ROI on this spend?

Step 3 involves ranking by priority: Must-have (business cannot operate without), Should-have (significant value, some flexibility), Nice-to-have (useful but not critical).

Step 4 involves building bottom-up: Start with must-haves, add should-haves to target, evaluate nice-to-haves against remaining capacity.

Common Discoveries

Subscriptions no one uses, overlapping tools doing the same thing, processes that could be simplified, vendors that could be consolidated, and marketing spend with unclear returns.

Making It Sustainable

Full ZBB every year is exhausting. Consider full ZBB every 2-3 years, rolling ZBB reviewing 2-3 categories deeply each quarter, or exception-based ZBB only for categories exceeding threshold.

The Mindset

ZBB is not about cutting costs blindly. It is about spending intentionally. Sometimes ZBB reveals you should spend more in high-ROI areas.
