What was done
On 8 May 2026 he writes in r/thesidehustle that a side project, a SaaS, sits at about 10k MRR beside a full-time job. Evenings went to invoices for enterprise clients, paying contractors, expenses and the books. A few weeks ago he connected the bank to Claude through MCP, and QuickBooks as well. He asks Claude to invoice a client, and writes that it is then done. Payments to contractors are queued until he approves them. Expenses are tracked, and the bookkeeping runs in QuickBooks through Claude. He writes that it went from 5-6 hours a week to maybe 20 minutes. Before, he sat with the invoices at 10pm.
How it went
He describes an invoice as something that is done when he asks, and payments as waiting for him. The post names no client, no bank and no invoice.
Worth knowing
"About 10k" and "maybe 20 minutes" are his words. It does not say which MCP app is used, only Claude. Check the original. This is not advice on bookkeeping or tax.
How to do it
- Connect the bank so that payments wait for you.
- Ask for an invoice draft for one client, and read it before it is sent.
- See what was posted. Do not pay a contractor before you have said yes.
Try it with Claude
Read [bank] and [books] for [period]. Draft an invoice to [client] from what is there. Do not send the invoice and do not pay [contractor] until I say yes.
Replace text in brackets with your own.
Done when. The draft has been read, and no invoice or payment has been sent unless you have said yes.
Safety rule. The agent does not send an invoice and does not pay until you say yes.
