One café. One month. Make it balance.

Why

You know the ledger.
You have never felt the mess.

Today that changes.

Two exercises

One to get right.
One to win.

You know the race is coming. You do not know what is in it.

The thesis

Build capex,
not opex.

Machinery you build once and redeploy forever. The next client goes hours to minutes. That is the whole game: for the bookkeeper, for Jaz, for us.

Scoring

Two kinds of answer.

Hand in

Your books in Jaz, plus 5 slides or a memo. Generate them with AI. Hand-crafting slides is opex.

Deterministic

Matches the key to the cent, or it bounces.

Judgment

Defend the reasoning, not a number.

Traps

Nothing is flagged. Spotting it counts.

Submitting

Checked on the spot. Errors bounce back and the clock keeps running. First accepted submission wins.

How to work

Whatever is fastest.

Tools

Dashboard, AI, code, MCP. Your call.

AI

For knowledge. Not for typing every line.

The client

On Telegram. Knows what happened, not how to book it.

Friction log

Open all day.

By midnight

Capex not opex.
Three levels up.

True for the bookkeeper. What Jaz sells. How we build.
