1.Introduction
This is the manual for the integration between JouwWeb and Lundify.
Please note: The integration only processes orders. The integration does not process refunds.
- This integration is a financial integration. It is not a logistics integration. It is not suitable for updating customers in Lundify, printing packing slips, or synchronizing products/inventory.
- This integration does not replace the work of an accountant. It saves time because you no longer have to retype documents. The accountant is still needed for advice, expertise, and control.
- Please note: Bjorn Lunden Lundify does not support OSS. This integration is therefore not suitable for OSS. If your webshop falls under OSS regulations, the advice is not to use this integration, or only for non-OSS sales.
Tip: Other customers using this integration found the tips in the FAQ for JouwWeb and in the FAQ for Lundify.
Installing the integration starts with signing up for a trial period, via our integrations page. After registration, you will receive an email containing an installation URL and login details. With this installation URL, you start the installation of the integration.
The installation is complete when both connection dots are green, and the settings in the Configuration tab have been entered and saved.
There is a trial period of 30 days.
If you want to install another integration, you can do so in the same way. Make sure you are logged out of the integration dashboard and preferably start the new installation in an incognito browser.
At the end of the trial or subscription period, the integration will not be automatically renewed. You will receive an offer for a one-year subscription or renewal by email at the end of this period. You can confirm the renewal by using the payment link in that email. Do you want to terminate the integration in the meantime? This can be done via the dashboard, tab Profile>>Cancel integration.
Are you switching to another web shop/accounting system and do you want to re-establish a connection? In this faq we explain how to do this.
2.How the integration works
The integration retrieves the orders from the webshop every hour and prepares them to be processed to Lundify.

At the start of processing an order, we perform a number of checks on the JouwWeb order:
- It is checked whether the total of the JouwWeb order is equal to the sum of the amounts in the order lines plus the shipping costs amount.
- If the order is an ICP order, the VAT number is checked.
- It is checked whether a corresponding VAT code exists in Lundify for the VAT in each line.
- It is checked whether the order has not already been processed.
Processing a Jouwweb order to Lundify takes place in three steps:
- It is checked if the customer already exists in Lundify. If not, the customer is created. Matching is based on the email address.
- When processing to Lundify orders, it is checked whether the products from the Jouwweb order are already present in Lundify. Missing products are created.
- The Lundify invoice is created and added.
3.Required: Lundify connection
A public key is required to connect to Lundify. You can find this key in your Lundify dashboard. Log in and go to Integrations. If you click on the right gear icon (2), a popup will appear. Activate the integration (3) and copy the key (the string in the box).

Then you log in on the dashboard https://uwkoppeling.webwinkelfacturen.nl. Enter the key in the Configuration, Authentication, or All Settings tab. This establishes the connection with Lundify.

4.Installation
After the installation, check using this FAQ, whether the integration works.
Installing the integration starts with signing up for a trial period, via our integrations page. After registering, you'll receive an email with an installation URL and login details. Use this installation URL to start the integration installation.

Webshop authentication
The authentication with the webshop runs via OAuth. Make sure you are logged out of your webshop before establishing the connection. Now click the red Connect button. A login screen for the JouwWeb webshop will automatically appear. If you log in, you will get a screen asking if you allow the connection. If you confirm this, the connection will be established.
If you want to re-establish the connection at a later time, you can always do so by clicking the Connect button.
Authentication Lundify
Establishing the connection with Lundify is done via the red Connect button in the Configuration tab. In the pop-up, you enter your Customer Code (this is the Lundify online 5-digit member number), and the token you created in the previous section. Please note, you need the entire code as a token, including the 1-part.
Multiple webshops can be present within one Jouwweb account. You can set here for which webshop you want to create the integration.
Processing status
You can specify which statuses orders should be processed to Lundify. You can select multiple statuses. The integration will never forward orders twice. The integration is protected against this.
To use Lundify, select an administration within your account. You also indicate in which journal the revenue should be posted and what the debtors account is. The journal for processing (individual) orders will be a Sales journal.
When configuring the VAT rates and general ledger accounts, a link is created between the VAT rates in webshop and the VAT codes and revenue accounts in Lundify. You can always make changes by clicking the blue 'Edit' button and selecting an option from the drop-down menus.
By default, all EU countries are shown in the list. You only need to configure the countries you sell to, and - if applicable - ICP and International.
The integration shows the standard VAT rates for Europe. You can adjust the VAT percentage with which you sell - left column. For example: By default, sales to Germany are set to 21%, but if you sell in the webshop with 19%, you can adjust this in the left column. Intra-Community (ICP) and international deliveries
The Intra-Community supplies / ICP option is intended for business-to-business deliveries within the EU. These sales are invoiced with 0% VAT. A VAT number from the customer is required. The International option applies to deliveries outside the EU. For these sales, the integration expects 0% VAT; otherwise, the sales cannot be processed. Separate VAT codes and general ledger accounts can be configured for both ICP and international deliveries.
Once the VAT settings have been configured and saved, you will always see the selected VAT rates. If you want to start over, you can use the grey 'Remove VAT settings' button. Your current settings will then be deleted and you can begin again.
You can create a link here between the payment methods in the webshop and a fixed debtor in your Lundify administration. Orders with a payment method from the list will then always be posted to this debtor. In that case, no new debtors will be created.
Note: It is not possible to set fixed debtors for ICP orders. For an ICP order, a valid VAT number must be transmitted. Therefore, a debtor will always be created in Lundify for an ICP order.
5.Day-to-day: From Jouwweb
Once an order has been processed, it cannot be processed again. Any order changed in the webshop after it has been processed will not be updated in Lundify.
Please note: The integration only processes orders, no returns / refunds.

6.Day-to-day: To Lundify
Creating invoices
The orders from Jouwweb are imported into Lundify as an invoice. This invoice is also immediately posted as a journal entry. For each order, the VAT and general ledger account are provided as configured during the installation of the integration.
When creating invoices, new debtors may be added to Lundify. By default, no products are added to Lundify, and the text line from the Jouwweb order appears in the Lundify invoice. It is possible to provide a product code. If you want this, please contact webcare@webwinkelfacturen.nl.
Cost center
It is possible to provide one default cost center to the Lundify invoice. One default cost center is possible per integration. Please contact webcare@webwinkelfacturen.nl stating the license key to make use of this.
When processing customer information, it is first checked whether the customer has been processed before. If so, this Lundify debtor is used as the debtor for the Lundify invoice. If the customer is not yet known, they are added to Lundify. Matching is based on email address. Please note: The integration only creates debtors. The integration does not modify debtors.
When processing to Lundify invoices incl. products, products that are not yet in Lundify will be added. See here for an explanation of how product codes are determined FAQ. The product is assigned the VAT code based on the VAT percentage in the order line and the general ledger account configured in the Configuration tab of the dashboard.
Please note: The integration only creates products. The integration does not modify products.
It is not possible to automatically send the created invoice in Lundify to the customer.
