What the agent did
He runs a small car-wash equipment service company and is not a programmer. With Claude Code he built an ERP that replaced the commercial package they used for years, plus agents that read the mailbox, create service calls, draft replies and prepare supplier orders. Anything with consequences goes to his phone on Telegram for approval.
Result, as claimed
"Our own ERP, in production, replacing the commercial package we used for years." He reviews "twenty decisions a day from the phone in a few minutes".
This is the result as the person described it in public. It has not been checked and is not a typical outcome.
Proof
Try it yourself
Use a coding agent to build back-office tools for a small firm, with written procedures and a human approval step for anything that matters.
Prompt
I run [type of business] with [team size] and I am not a programmer. Help me automate [one job, for example turning manufacturer emails into service calls]. First, write the procedure for this job with me step by step and save it as a file. Read it before you write any code. Build the smallest working version on a test copy, not live data. Anything that creates a document, changes a price or sends something must ask me for approval on [Telegram or email] first. Write tests for any money logic.Prompt: starter by Solopreneur Code

Steps
- "Make the AI read before it writes": write your procedures down first.
- Separate "propose" from "do": route anything touching money, customers or production through a human.
- Build and test on a separate copy, never straight on production.
- "Back up, and restore": test your backups on a clean machine.
Watch out: He says you become the systems engineer, so you need to understand enough to spot when the agent is wrong and to fix what breaks.
