TKG Invoice FAQ
Questions before you open the workspace.
Is TKG Invoice only for German companies?
No. Germany-first defaults are supported, while companies can configure country, currency, locale, tax and invoice language for their own workflow.
Can more than one person use a company workspace?
Yes. Company owners can add team members and use roles to control who manages business records.
Can it create PDF invoices?
Yes. Invoices and estimates can be prepared in the workspace and downloaded as professional PDFs with company branding.
Does TKG Invoice replace full accounting software?
It is focused on invoicing, payments, expenses and operational reporting. Formal accounting and tax filing requirements should still be handled with the appropriate professional or accounting system.
