e-conomic is used by both large and small organizations. Automate manual processes – let customers pick up their invoice themselves.

Microsoft Dynamics

If you use Dynamics NAV, C5, AX and 365, we can easily create a site where users can log in and download their invoice.


Do you use SAP, and want your customers to be able to download their invoices themselves? We got a solution!


Simple invoicing

We have developed a system that makes it easy for you and your customers to manage invoicing.
Customers log in to a simple website with their phonenumber and a password.
Invoice and information on whether the invoice has been paid, will be retrieved directly from your accounting system.


Focus on the right thing

Basically it is a matter of removing as many time-consuming and manual processes as possible.
We suggest that you build a simple website that your customers can log in to.
Here they retrieve invoices directly from your accounting system. It saves you and your colleagues this time-consuming interaction.

Noticeable difference

How many invoices do you send to your customers monthly, and how long does it take to find the given invoice that a customer might request?

Customer interaction and searching in your accounting system takes time.

Wouldn’t it be easier if the customer got the invoice sent automatically, or could download the invoice themselves?

The value is noticeable and our online invoicing brought great satisfaction, at Den Luddovne Bogholder, Frederik Sandgrav.
