The Gut Decision Problem
Software investment decisions are usually gut calls: "yes, let's do it" or "too expensive." Both without math. Both wrong. Here is the framework.
The Four Sources of ROI
Time savings: (Hours saved per week x 52 x hourly labor cost) = annual labor savings. Example: 3 employees x 10 hrs/week x $35/hr = $54,600/year.
Revenue uplift: (Revenue baseline x improvement %) = annual increase. Example: $500K revenue x 15% conversion lift = $75,000/year.
Error reduction: (Error rate x avg cost per error x annual volume x reduction %) = savings. Example: 2% error rate on 12,000 invoices/year at $150 each, 90% reduction = $32,400/year.
Scale enablement: What is the ceiling of your current manual process? What would 2x capacity enable? This is harder to quantify but often the most valuable number.
A Real Example
Mortgage brokerage loan processing platform. Build: $35K. Hosting: $1.2K. Training: $2K. Total cost: $38,200.
Benefits: 4 processors x 8 hrs/week saved x 52 x $40 = $83,200. Faster closings driving 8% more volume = $120K. Error reduction = $18K. Total annual benefit: $221,200.
Payback period: 2.1 months. Three-year ROI: 1,537%.
Why Businesses Still Say Too Expensive
Because they calculate cost in isolation. $35,000 is a lot is a feeling. $35,000 that returns $221,000 in year one is an investment. Run the math. It almost always works.
We Do This Before Every Project
Before scoping, we run these numbers together. If the ROI is not clear, we say so. We would rather walk away than build software that does not pay for itself.
