Built for a fitness coaching business managing 400+ clients across multiple currencies, pricing tiers, and 24 months of payment history — with no single place to see any of it clearly.
The problem
What was breaking before this system existed.
Revenue looked healthy on the surface but nobody could tell if churn was quietly rising underneath it
Answering "how much has this client paid us in total?" meant 10 minutes of digging across multiple tools and payment records
Ad spend was being compared to this month's cash — not to the real lifetime value of the clients it acquired
Retention was tracked as a feeling, not a number — so churn was discovered when it happened, not before
What I built
A single source of truth for every dollar that enters and leaves the business.
Built across four connected modules in a live spreadsheet system designed to be migrated into a custom web application. Every client, every payment, every ad dollar, and every churn event is tracked from first impression to last payment — so the business stops operating on gut feel and starts operating on data. The four modules are designed to compound: each one feeds the next, and together they answer every strategic financial question the business has.
This system was built for a business that looked like this.
A coaching business past the early stage — enough clients and enough revenue that the numbers were getting hard to track, but no infrastructure to see them clearly in one place
Making sales consistently but unable to answer basic questions like "where is cash actually coming from this month?" or "which clients are our highest LTV and why?"
Spending on ads without knowing the true payback period — because first-month cash and lifetime value are two very different numbers
What it replaces
Before this system, the business was flying blind on the numbers that matter most.
I can build something like this for your business.
Every system I build is custom — scoped around your team, your workflow, and the specific operational problems you're trying to solve.
