To activate Kustom Checkout in E37, you need to create and configure a new payment method.

Create a payment method group

Before adding a new payment method, ensure that you have created a payment method group that the payment method will belong to.

  2. Navigate to E-handel → Kassa → Betalsätt.

Add a new payment method

  1. Click Lägg till betalsätt.

Configure basic settings

  1. Check the box Aktiverad to make the payment method available in checkout.

  2. If available, select an ERP-koppling to receive enriched order data in your ERP. Otherwise, leave it as Ingen koppling.

  3. Select the appropriate Payment Method Group.

  4. Choose which customer types are allowed:

    • Tillåt privatperson
    • Tillåt företag/organisation

    At least one must be selected.

  5. Choose whether the payment method Kräver person-/orgnummer.

  6. As Payment Module, select Kustom Checkout.

Configure payment method details

  1. Enter a Title for the payment method.
  2. Optional: Add a Description shown in checkout.
  3. Optional: Add Order Confirmation Text shown in the confirmation email.
  4. Click Spara.

Configure fees

  1. Open the payment method again.
  2. Go to the Avgifter tab.

Fixed fee (optional)

If the fee should always be the same:

  2. Add intervals if needed using Lägg till intervallrad.

Example:

  • Otherwise 49 SEK

Note:

  • Leaving Till empty means “and above”
  1. Click Spara.

If you see the error:

Det får inte förekomma hål eller överlappningar i intervallet

It means intervals overlap or leave gaps.
