This month it was time again to file the quarterly sales tax (BTW) return for my UX business.
Since I just got access to Anthropic’s top model again, Claude Fable 5, I decided to test whether it could handle it for me.
I gave it my accounting Excel, three months of business bank statements, and my invoice PDFs.
Filing by hand normally takes me about three hours. Fable did it in 10 minutes. I spent another hour verifying the numbers — everything checked out.
Beyond producing a clean, updated accounting Excel, it flagged a couple of missing invoices and noticed my annual credit card fee had gone up from last year. It also saved the workflow and my Excel conventions, so next quarter should go even faster.
The path to AI handling all my admin is getting hard to ignore.
