DigiFakt was created to make the creation of invoices, credit notes and offers fast and easy. The system is designed to be as hands on as possible. At first you define some customers as well (if you want that) some products from which you create your invoices etc... The biggest advantage is that the database is not stored on your local machine but on a server in the datacenter. This makes it so that you never need to worry about your data when your system crashes. As an extra service we can even mail you your backups.
You can test the system at DigiFakt It speaks for itself that a personal system is secured so that only you and your employees can use it.
