I build small software products on my own, with AI agents doing a large share of the work, and I spent about ten years running finance operations before that. These are notes from both: what shipped, what broke, what a thing actually cost, and the parts that did not work. Written plainly, with the real numbers in them.
Rack Up is live on both stores at $2.99. What adversarial AI review caught, what only running the build on a device caught, and the store settings nobody warns you about.
A five-number weekly scorecard that covers most operating decisions: cash on hand, cash coming in, cash going out, runway, and one revenue driver.
How to turn reconciliations from a monthly scramble into a boring, repeatable system that anyone on the team can follow and defend.
Why the person who runs the finance process should also build the tools, and what AI changes about that combination.
A framework for deciding which tasks earn automation and which manual steps are quietly doing a job you want to keep.
A practical month-end close checklist that gets a small finance team to a clean, fast close without buying new software.
These notes come out of the work itself: the apps, the operations behind them, and the tools I build to run both. The rest of the company is one page away.
