After ~15 years as an employee I'm back in #freelancer land. Acquired a interesting graph project at a pretty large company in #Germany. Unfortunately I cannot share details due to NDA.
could need some help with:
a) what are you freelancer folks using for tracking billable hours? I've used https://mite.de/ long years ago
b) in #Germany B2B invoices need to follow #ZugFERD standard. What tooling are you using for this? Ideally something that works on #Linux.
