Fractional CFO for Manufacturing Companies
Financial leadership that bridges the factory floor and the boardroom.
Key Takeaways
- •Cost accounting accuracy is essential—product decisions depend on true costs
- •Inventory represents a major working capital investment requiring optimization
- •Capacity utilization directly impacts unit economics and profitability
- •Make vs. buy decisions require thorough financial analysis
Manufacturing companies face unique financial challenges at the intersection of operations and finance. Cost accounting, inventory valuation, capacity planning, and capital expenditure decisions require a CFO who understands how the factory floor connects to financial performance.
A fractional CFO with manufacturing experience can bridge this gap—ensuring accurate product costing, optimizing working capital tied up in inventory, and making capital investment decisions that drive returns.
Cost Accounting: The Foundation
Accurate cost accounting is the foundation of manufacturing finance. Without knowing true product costs, pricing, mix, and production decisions will be flawed.
Cost Components
Direct Materials
Raw materials and components that go into the product
Direct Labor
Labor directly involved in production
Manufacturing Overhead
Indirect costs: utilities, supervision, depreciation, maintenance
Standard Costing and Variance Analysis
Most manufacturing companies use standard costs—predetermined estimates of what products should cost. The CFO's job includes analyzing variances between standard and actual costs.
Common Variances
- • Material price variance
- • Material usage variance
- • Labor rate variance
- • Labor efficiency variance
- • Overhead spending variance
- • Overhead volume variance
What Variances Tell You
- • Are we buying materials efficiently?
- • Are we using materials efficiently?
- • Is labor productive?
- • Is overhead under control?
- • Are we running at target volume?
The Danger of Inaccurate Costs
If product costs are wrong, everything downstream is wrong—pricing, profitability analysis, make vs. buy decisions, product mix optimization. A manufacturing CFO must ensure cost accuracy, not just accept what the system produces.
Inventory Management
Inventory is typically a manufacturer's largest working capital investment. Optimizing inventory levels balances customer service with cash utilization.
Inventory Types
Raw Materials
Components and materials waiting to be used in production
Work in Process (WIP)
Partially completed products currently being manufactured
Finished Goods
Completed products waiting to be shipped
Key Inventory Metrics
- Inventory turns: COGS / Average Inventory (higher is generally better)
- Days inventory outstanding: (Inventory / COGS) × 365
- Slow-moving inventory: Items not moved in 90/180/365 days
- Obsolete inventory: Items that may never sell
- Fill rate: Ability to ship customer orders from stock
Inventory Write-Offs
Inventory on the books doesn't always have value. A CFO must ensure proper reserves for slow-moving and obsolete inventory. This affects both profitability (write-offs hit the P&L) and cash flow (inventory you can't sell is cash you can't recover).
Capacity Planning and Utilization
Manufacturing capacity represents a major fixed cost. How well you utilize that capacity directly impacts unit economics and profitability.
Capacity Utilization
Capacity Utilization = Actual Output / Maximum Possible Output
Under-utilized: Fixed costs spread over fewer units = higher unit cost
At capacity: Optimal efficiency but no room for growth
Over-utilized: Overtime, quality issues, equipment wear
OEE: Overall Equipment Effectiveness
OEE is a comprehensive measure of manufacturing productivity that combines:
- Availability: Uptime / Scheduled time (equipment running when planned)
- Performance: Actual speed vs. ideal speed
- Quality: Good units / Total units produced
OEE = Availability × Performance × Quality. World-class is 85%+; average is 60%.
Make vs. Buy Decisions
Manufacturing CFOs frequently evaluate whether to make components internally or purchase them from suppliers. This analysis requires understanding true costs.
Factors Favoring Make
- • Have excess capacity
- • Core competency/strategic value
- • Quality control requirements
- • Proprietary technology
- • Reliable internal cost advantage
Factors Favoring Buy
- • Supplier has scale advantage
- • Not core competency
- • Capital required for production
- • Capacity constraints
- • Variable demand (outsource flexibility)
Full Cost vs. Incremental Cost
A common mistake is comparing supplier price to fully-loaded internal cost. If you have idle capacity, compare to incremental cost (materials + direct labor + variable overhead). Fixed costs don't go away just because you outsource.
Capital Expenditure Decisions
Manufacturing requires ongoing capital investment in equipment, facilities, and technology. The CFO's role is ensuring these investments generate appropriate returns.
CapEx Analysis Framework
- Business case: What problem does this solve or opportunity does it capture?
- Cost estimation: Total cost including installation, training, disruption
- Benefits quantification: Cost savings, capacity increase, quality improvement
- ROI calculation: NPV, IRR, payback period
- Risk assessment: What could go wrong? What are the assumptions?
Common CapEx Categories
- • Replacement equipment (maintaining current capacity)
- • Expansion equipment (increasing capacity)
- • Efficiency improvements (reducing cost per unit)
- • Quality improvements (reducing defects/rework)
- • Compliance/safety (required investments)
