ByBart · App 01 — Bart's Work Time
A time tracker and invoicing app built by a Swiss tradesperson, for Swiss tradespeople. CHF, German invoices, the right VAT — done.
What it does
Home, time, materials, tasks, accounting. Each tab is one part of the job — and the Swiss-specific bits are baked in so you stop fixing them by hand.
Clock in on site, switch jobs, edit a running entry. It survives a phone restart and keeps counting — no lost hours. Today, entries and week totals up top.
Tracked time turns into a clean PDF invoice in CHF, in German, with the correct 8.1% / 2.6% VAT. Drafts, open and paid at a glance — plus offers and customers.
Log the parts and receipts per client, then drop them straight onto the invoice. A saved library means no retyping the same line every week.
One dashboard: uninvoiced entries waiting to be billed, unfinished invoice drafts, overdue tasks, and setup items that still need your attention.
To-dos with priority and due dates, sorted so the overdue ones surface first. Tie them to a client so nothing slips between jobs.
Cellars and new builds with no signal? It keeps working and syncs when you're back. Pull monthly, quarterly or yearly totals when the accountant calls.
