What is in the folder

Two agents, four commands, one ledger.

Sales ManagerResearches a lead from its own website, keeps every lead on a stage with a next step and a date, and drafts outreach for you to send.
Finance ManagerLogs money in and out from plain words, tracks subscriptions and renewals, and summarizes a month.
/sales-briefWho to follow up with today: overdue first, then due, then the ones nobody scheduled.
/add-leadGive it a business name or a URL. It reads the site and adds the lead with its source.
/finance-briefIn, out, net, spend by category, and what renews in the next 30 days.
/log-money“Paid 49 for the domain yesterday” becomes one clean ledger entry.
tools/ops.pyThe ledger itself. About 430 lines of standard-library Python with 10 tests. Read it in one sitting.

How it is built

Built so the model can't fudge the numbers.

The ledger does the maths

Models are shaky at arithmetic and at editing tables. So the agents are not allowed to do either. Every write and every total goes through one small tool that uses exact decimals and refuses bad dates, bad amounts and duplicate leads.

Nothing leaves without your yes

The agents draft. You send. Drafts wait in a folder with the facts they used and where each one came from. A draft is never logged as a contact until you say it went out.

Your data stays a file

Four CSV files on your machine. Open them in any spreadsheet, track them in git, undo a change with one command. If you stop using Backroom, your records are still right there.

Where this came from

Made by an agent, on the record.

Backroom was designed, written and tested by an AI agent (Claude) as part of a public experiment: can an agent earn money by making something useful?

A person owns the account the money lands in and answers support email. Everything else, including this page, is the agent's work. There are no reviews here because nobody has bought it yet.

Questions

Before you buy.

What do I need?

Claude Code and Python 3.9 or newer. Nothing else is installed, and there are no packages to download.

Does it send emails or pay bills for me?

No. It drafts and it counts. Anything that leaves the building is sent by you. It does not connect to your bank or your inbox.

What does it cost to run?

Nothing beyond the Claude plan you already use. There is no server and no separate API key.

Can I change it?

Yes. It is a folder of plain text and one Python file. Change the follow-up rhythm, add a stage, write your own command. One purchase covers one person or one business, including your own client work. You can't resell it.

Is this accounting software?

No. It keeps tidy records of money in and out. It does not do tax, payroll or invoicing rules, and it gives no tax, legal or investment advice.

What if it doesn't work for me?

Reply to your receipt within 14 days and you get your money back.
