Frequently asked questions

Is the invoicing really free?

Yes. Creating and sending invoices, tracking payments and using the customer register are free for all businesses. Optional paid services exist only for custom development and tailored integrations.

Can I invoice from a case or an order?

Yes. Cases, tickets and orders can be converted to invoices, so the work you already logged becomes a bill without entering the same data twice.

Does invoicing connect to the customer register?

Yes. Invoices are linked to customers in the built-in free CRM, so you always see the full history of a customer — cases, orders and invoices together.
