Fakturama is a tool for creating invoices, delivery, order and many other documents. You can create customers (debtors and creditors) and use them in your documents. The included product management helps you to manage your products (with categories, scaled prices and different VAT amounts). You can define your own templates for your documents, which will be created in LibreOffice. Furthermore, you can connect to your web shop and get all orders, customers and products for easy management in Fakturama.

You can export and import your data in several formats like OpenOffice format, VCard or CSV. SwissCode and other types of payment facilitations are also possible.
