POS integration - MplusKASSA

To set up the integration with MplusKASSA, Mr. Einstein needs a number of technical details from your MplusKASSA environment. You request these from your POS supplier (kassaleverancier), the company you buy your cash register system from. This article explains, as an employer or administrator, how to set up the cash register integration (kassakoppeling) with MplusKASSA. Are you setting up the integration for the first time? Then contact Mr. Einstein first (see step 1).

Step 1: Contact Mr. Einstein first

Are you setting up the cash register integration for the first time? Then contact Mr. Einstein first at [e-mail]. We switch on the integration for your location in the background. Until we have done this, you will not yet see the tab to set up the integration in the portal.

Step 2: Request the details from your POS supplier

To set up the integration you need a number of technical details from your MplusKASSA environment. You request these from your POS supplier (kassaleverancier). In the connection screen (Koppelingen) of Mr. Einstein a ready-made email is available that you can copy and send. This email is in Dutch. Add your own company and contact details. Without these details the integration cannot be set up and the systems cannot communicate with each other.
