One platform instead of isolated tools
All applications share data, users, and a consistent interface. You do not have to sync anything between tools, and new team members quickly find their way around.
Shared master data
You enter customers, products, and VAT rates once and use them in quotes and invoices alike.
Consistent permissions
You manage users, roles, and permissions centrally for all applications.
Central snippets & terms
You maintain snippets for recurring texts and legal documents in one place and use them in all documents.
Applications
Invoicing
Let customers accept quotes online, send invoices with Swiss QR bills, and keep track of payments.
