Overruns from Legacy Spend and Non-Strategic Line Items
Definition
Marketing services firms commonly carry forward legacy spend (e.g., underused tools, outdated sponsorships, low-performing channels) because budgets are rolled over annually instead of rebuilt from zero, resulting in chronic overspending on low-ROI activities. Zero-based budgeting guidance notes that major corporations cut substantial non-essential marketing costs by rebuilding budgets from scratch and eliminating legacy spend.[1]
Key Findings
- Financial Impact: For an agency handling $5M/year of OPEX and pass-through client marketing spend, eliminating just 10–15% of legacy and low-impact spend via zero-based budgeting can avoid $500,000–$750,000/year of unnecessary cost.[1]
- Frequency: Monthly
- Root Cause: Budgets are built on prior-year baselines rather than a zero-based review; weak approval tiers and lack of rigorous ROI analysis allow redundant software subscriptions, outdated campaigns, and non-strategic sponsorships to persist year after year.[1][4]
