Interviewer: What financial blind spot affects revenue decisions?
Robert Finch, Financial Controller: Standard expense categories group costs in ways that hide product-level economics. A professional services firm I worked with categorized all labor as a single line item. When we broke it down by service offering, we discovered their consulting engagements averaged 42% gross margin while training services ran at 68% margin.
The training team had been requesting more headcount for two years. Finance kept denying it because overall labor costs were high. Meanwhile, they approved three consulting hires based on revenue growth. The margin difference meant each training hire would have generated $180,000 more in contribution than a consulting hire.
Activity-Based Insights
Interviewer: How granular should expense tracking be?
Robert Finch: Enough to understand unit economics by offering, customer segment, or channel. A manufacturing company tracked production costs by facility but not by product line. When we implemented activity-based tracking, we found their highest-revenue product line actually operated at negative contribution margin once you properly allocated machine time, quality control, and logistics.
They were losing $47 per unit on a product generating $3.2 million in annual revenue. The volume made it look successful. The detailed economics showed they'd be more profitable not selling it at all.
Hidden Cross-Subsidies
Interviewer: What patterns emerge from this analysis?
Robert Finch: Cross-subsidies between products, regions, or customer segments. A SaaS company had three pricing tiers: basic at $29 monthly, professional at $79, and enterprise custom pricing. Looking at support costs, basic customers consumed an average of $12 in support monthly. Professional customers used $31. Enterprise customers, who paid an average of $840 monthly, used $89 in support.
The professional tier was actually unprofitable after fully loading costs. They were subsidizing it with enterprise margins. Once they saw the numbers, they increased professional tier pricing to $99 and reduced some automated features for basic. Annual profit increased by $420,000 without losing significant customer volume.
Implementation Reality
Interviewer: What does setting this up actually require?
Robert Finch: Time tracking for labor-intensive businesses. Cost allocation rules that reflect actual resource consumption. System modifications to track costs at the right level of detail. For that manufacturing company, implementation took four months and required changes to their ERP system, plus training 15 people on new cost coding procedures.
The payoff came from making different decisions. They discontinued two product lines, repriced three others, and shifted production capacity. First-year impact was $1.9 million in additional operating profit. But getting there required investment in both systems and process changes.
Most companies have the data somewhere in their systems. It's just not organized to support these decisions.
