Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Claude can edit clients, the Tax Overview opens up, and a client's year at a glance.
- Claude Desktop on the Mac can change a client: ask Claude to update one and Admin opens that client's own form with the changes filled in, for you to check and save. Claude also sees the whole client record now, payment terms and your own client fields included, and can set them when it adds a client.
- A client's sheet opens on an Overview tab: one bar per month with that client's turnover in the currency you bill them in, split by job status. Job statuses wear the same colours everywhere.
- Tax Overview: tap Netherlands, EU or Rest of World to see what is behind the figure, line by line, with the total at the bottom. EU (box 3b) and the EU Services list count jobs by the period you delivered them, so both always match. Rest of World no longer says Box 3a.
- A renamed client keeps its old invoices everywhere: the Tax Overview, the client sheet and the payment lists find an invoice's client through its jobs when the name no longer matches.
- Claude Haiku 5.5 and Claude Sonnet 5.5 are in the model list, and chat titles are named by Haiku 5.5. Claude Sonnet 4.5 is gone; anything pinned to it runs on Sonnet 5.5.
- About shows a copyright line that moves with the calendar.
