Why this can go viral
Detailed analysis
Zero-based budgeting rebuilds spend from business need instead of last month plus 10%. It helps identify unused tools, duplicate vendors, low-ROI agencies and vanity projects.
Practical example
A startup finds 37 SaaS tools, 11 unused seats and two overlapping analytics platforms. ZBB review saves ₹18 lakh/year without cutting core product or sales capacity.
Evidence and control checklist
| Area | What to check | Evidence to save |
|---|---|---|
| Definition and owner | Define zero-based budgeting, owner, source system and review frequency. | Metric dictionary, owner matrix and version log. |
| Source data | Books, bank, CRM, payroll, billing, contracts or statutory filings used. | Source extracts and reconciliation sheet. |
| Computation logic | Formula, assumptions, exclusions and period consistency. | Working paper and CFO sign-off. |
| Decision impact | How the output affects pricing, hiring, spend, funding or compliance. | Management note and action tracker. |
| Diligence evidence | Whether an investor/auditor can verify the number independently. | Indexed folder with contracts, reports and approvals. |
