FREE TCO CALCULATOR · BUILD VS. BUY
A free, working calculator that models the true three-year cost of building your billing system versus buying it — side by side, on your own engineering rates, timelines, and usage. The first of its kind built for AI infrastructure.
Illustrative. Your real numbers may point either way: that’s what the calculator is for.
What You’ll Get
Most teams settle build vs. buy in a meeting, on instinct. This settles it with your own math, in an afternoon.
1. Your 3-year build cost, itemized
Across all 16 components a billing system actually requires: not the 3 or 4 most teams scope.
2. Your 3-year buy cost
Modeled on your real usage and growth, not a generic benchmark.
3. The crossover point
Exactly where building stops being cheaper than buying: on your numbers.
4. Time-to-first-pricing-model
For each path: because the roadmap cost is as real as the dollar cost.
HOW IT WORKS
Enter your email; the working spreadsheet arrives immediately. No sales gate.
Engineering rates, timelines, headcount, usage.
Granular inputs, your reality.
Build vs. buy, side by side, with the crossover point — in minutes.
