If you use the economic system e-conomic then you can offer your customers to pay their invoices online using Quickpay.

When you send your customers an invoice from e-conomic, they receive a guide and a link where they will be able to pay the invoice using credit card.

The only requirement is that you have an account for e-conomic as well as Quickpay. No extra cost and rather easy setup.

Visit https://www.e-conomic.dk for more information


Quickpay setup

  1. Go to Settings > External Integrations > E-conomic in the Quickpay Manager


  3. Then click on GO TO E-CONOMIC

  4. You will now be redirected to e-conomic. Log in with your economic credentials.

  5. Click ‘Tilføj app’ / ‘Add app’


  6. You will now see the token.

    Copy this, and paste it into the Quickpay Manager together with your e-conomic agreement no.


Setup in e-conomic

First step in e-conomic is to navigate to “Categories and Units” > “Number series” and change “Invoice number” so “Next number” is at least 4 digits long.

Now the basic setup is complete, and you only need to add a link in the mail to your customer. In the body text add the following link:


MERCHANT_ID is replaced with merchant ID og AGREEMENT_ID with payment_window agreement ID, both can be found in the Quickpay manager under “Settings” > “Integration

You can also add the following parameters:





Remember to check “Remember body text” for future use.

Now everything should work. We recommend that you make a test invoice to confirm that everything is working properly.

Please note

Please be aware, that the payment is not registered as paid in your e-conomic. That should only be done, when you balance your books with your bank statements.

Please note your invoice numbers need to be at least 4 digits long.

Please note that e-conomic administrative accounts (for accountants and bookkeepers) will not work. Only normal e-conomic accounts with api-access can be used.

Should you encounter the error below, you are most likely trying to use a user that does not have access to the API, switch the user and input the correct info on your Quickpay account under the e-conomic integration.
