Use case overview
Cowork with Claude's Chrome extension prepared accounts from invoice PDFs, then logged into Elster and submitted the overdue Q3 2025 VAT forms.
Reported experience
What they did
Gave Claude Cowork a project folder holding invoice and receipt PDFs and asked it to prepare accounts for each quarter. Logged into Elster, then used the Claude Chrome extension to locate the forms, fill them with the prepared data, and submit the Q3 2025 VAT statements. Recorded the browser session and later asked Claude to redact personal details and speed the video up 3x.
How it went
The overdue Q3 2025 statements were filed. No other results or shortfalls reported.
Worth knowing
Used only Anthropic's off-the-shelf Cowork and Chrome extension with no programming.
Example prompts
