Onboarding steps:
Register your cash register with Skatteverket
All cash registers must be registered with Skatteverket. Follow these steps:
Visit Skatteverket's e-service
Select "Anmäl, ändra, felanmäl och avanmäla kassaregister"
Log in using BankID, Freja ID, or AB Svenska Pass
Next step is to register the Control Unit (Kontrollenhet).
Begin by registering the control unit. This is a required first step before you can register your cash register with Skatteverket.
Important: You must use these exact details
All cash registers must be connected to a certified control unit. We provide a connection to TCS (InfraSec's) cloud-based control unit.
Copy these exact details into the Skatteverket form—do not modify or substitute any information:
Manufacturer (Tillverkare): TCS

Control unit's address (Kontrollenhetens adress):

Postal number (Postnummer): 111 37
Address (Adress): Tunnelgatan 2
City (Postort): Stockholm
Above pre-configured details connect you to our certified control unit infrastructure.
Next step is to register your Cash Register.
Before moving forward, review all the control unit information you entered above to ensure it's correct. Once verified, proceed to register your cash register with Skatteverket in the next step.
Next, fill in the form with the information below.
Some details are fixed values provided by Kustom (our certified system), while others are specific to your business and the cash register (scroll down to see pictures).

If you plan to use multiple devices and MPOS apps simultaneously, we recommend creating and registering a separate cash register for each one. Once registration is complete, you'll receive confirmation from Skatteverket within 2 weeks—but you can start selling with MPOS right away.
Note: In the form at Skatteverket, do NOT click in “Samma adress som kassaregistret”. Since the journal memory and cash register is cloud based (digital) the correct address is Kustom which is the manufacturer of that software and not a physical device/hardware.
