The German translation they added is so poor that invoices cannot be used. Please don't use Google Translate or similar for business software...
Important fields like an item description on the invoice are missing. Text fields cannot be customized or are too short to give valuable legal context. My last few emails to support were not answered instead I get automated emails asking me to give them a good rating. This is frustrating.
Finmei is not ready and still needs major upgrades before it can be used in a professional setting.
