See what you need each morning.

Overdue invoices, the DATEV transfer that is due, an accepted quote without an invoice: workload.zero sorts by money, deadline and handover and offers the next step right away.

Features

From the hour to the accountant.

Every tracked hour becomes a timesheet, every approved timesheet an invoice, every invoice ends up at DATEV.

Track time wherever you are.

The week at a glance, entries in the side panel, billable or internal. Suggestions from commits and copied days save you the typing.

Approval instead of chasing.

Timesheets per client and month, with confirmation, approval or rejection including a comment and a new version. Export as PDF or CSV.

The invoice writes itself from the hours.

Pick a timesheet, sender and client come from the project, the line items are already there. backoffice.zero checks the mandatory details before sending.

Quote, acceptance, invoice.

Line items with estimates from comparable projects, sent by email, accepted online by name. The accepted quote becomes the invoice.

Your accountant has everything.

Invoices go to DATEV in batches. If a transfer fails, you see it right on the invoice and fix it in the panel.

Cash flow and tax reserve.

Account balance, tax reserve and money you can actually spend at a glance, with bank accounts and forecast. Coming with workload.zero.

With Claude

Ask instead of clicking.
