1.Introduction
This is the manual for the integration between Mijnwebwinkel and Billit.
This integration ensures that orders from the Mijnwebwinkel webshop are processed daily to invoices in Billit. Because the orders enter the merchant's accounting system directly, it saves time on financial administration.
Please pay special attention to the following
- This integration is a financial integration. It is not a logistics integration. It is not suitable for updating customers in Billit, 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.
Tip: Other customers using this integration found the tips in the FAQ for Mijnwebwinkel and in the FAQ for Billit.
Install integration
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.

2.How the integration works
An order from the Mijnwebwinkel webshop is processed to an Billit invoice. It is possible to ensure that the Billit invoices refer to a product in Billit. We call this posting to products. This can be requested via webcare@webwinkelfacturen.nl.
New orders from your webshop are retrieved at least once per hour. Additionally, every night previous orders that have not yet been forwarded to your accounting system are reviewed. If the status of an order has changed so that it may be processed to Billit, the integration will do so.

Pre-check orders
At the start of processing an order, we perform a number of checks on the Mijnwebwinkel order:
At the start of processing an order, we perform a number of checks on the Mijnwebwinkel order:
- It is checked whether the total of the Mijnwebwinkel order is equal to the sum of the amounts in the order lines plus the shipping cost amount.
- If the order is an ICP order, the VAT number is checked.
- It is checked whether a corresponding VAT code exists in Billit for the VAT in each line.
- It is checked whether the order has not already been processed.
Processing orders
Upon a successful check, the Billit invoice is created and processed to Billit. The debtor data is placed in the Billit invoice. Billit itself checks if the debtor is already present. One can choose to also add the products from the order. This option can be requested from us.

Post-check
After the order has been forwarded and a success message from Billit has been received, the order is marked as handled. The Mijnwebwinkel order appears at the Reporting tab on the dashboard.
If Billit returns an error while processing the order, the order appears in the Errors tab on the dashboard. Via the yellow button More info more information about the problem can be found. Via the red button Report problem can the order with all necessary information easily be submitted to us after you have tried to resolve the problem yourself. If the problem is solved, in some cases the orders can be processed again with the blue Process button.
Data
Information about the data that is processed can be found in the section Day-to-day: To Billit later in the manual.

3.Required: Mijnwebwinkel key

You can find the key itself under the API overview. If you click on Show token, the key will appear. Copy this into the login screen for the connection.
4.Installation
After 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.
Activating the integration consists of three steps:
1. Establishing the connection with the Mijnwebwinkel webshop. Through this step, you authorize the integration to read the data from your webshop.
2. Establishing the connection with Billit. This authorizes the integration to write transactions to your Billit administration and read information.
3. Configuring additional data, such as the VAT settings.
Before the integration can be used, the terms and conditions must first be accepted. The terms and conditions are based on the general ICT Terms and Conditions (industry organization) and the general GDPR guidelines. We also need a name, email address, and the country of the webshop. 
Authentication Mijnwebwinkel webshop:
Authentication with your Mijnwebwinkel webshop is done via the API key you created in a previous section. Click the red Connect button next to Mijnwebwinkel and enter the API key in the popup window. If the connection is correctly established, the indicator will turn green. If the connection is not established, check whether the API key for the correct provider - being Webwinkelfacturen - was created in the previous section.

If the connection is correctly established, the indicator will turn green. If the connection is not established, check whether the API key for the correct provider - being Webwinkelfacturen - was created in the previous section.
Authentication Billit
The authentication with Billit runs via OAuth. Make sure you are logged out of Billit before starting the connection. You now click on the red Connect button. A login screen for your Billit account will automatically appear. When you log in, you will get a screen asking if you allow the connection. If you confirm this, the connection with Billit is established.
If you want to re-establish the connection at a later moment, you can always do so by clicking the Connect button.
Invoice layout Billit
It is possible to link an invoice layout to the invoice in Billit. At this moment, the templateID of the layout must be entered. At a later stage, the integration will show a list of available invoice layouts. This functionality is under development.
Payment status Billit
It is possible to provide the payment status to Billit invoices. The options are always set to paid, never set to paid, or set to paid depending on the status in the webshop. If you choose the last option, it concerns the payment status at the time of processing. If the payment status in the webshop changes at a later moment, the invoice in Billit will not be updated.
Configure VAT rates and general ledger accounts
When processing to the Billit accounting system, the VAT percentages are transferred directly. Therefore, there is no possibility to post to separate VAT codes or ledger accounts.

5.Day-to-day: From Mijnwebwinkel
In this section, we show how we retrieve the orders from the webshop.
Processing schedule: New orders from your webshop are retrieved at least once per hour. Additionally, every night previous orders are reviewed that have not yet been forwarded to Billit. The integration goes back a maximum of 60 days in time to update orders. The reason is that the integration is allowed a maximum of 60 requests per hour.
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 Billit.
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 Billit.
Status processing:
For each order, the status of the order is reviewed. Orders with the status:
- Paid
- Shipped
- Paid and shipped
are processed to Billit.
It is possible to have orders processed to the accounting system for other statuses. You can easily set this in the Configuration tab of the dashboard.
VAT numbers: For business orders within the EU, outside the Netherlands, a VAT number is mandatory. The integration checks for this and also verifies the correctness of the VAT number. In Mijnwebwinkel orders, the VAT number is located in the billing address of the order's debtor.

Field-level specification Billit
Creating invoices
When creating invoices, the customer information is placed in the invoice. Therefore, no separate customer is created. Billit handles the matching of the debtor data with already existing debtors in Billit itself.
Create debtor
When processing customer information, all data is provided in the sales transaction and Billit will process it further.
When processing customer information, all data is provided in the sales transaction and Billit will process it further.
Create products
Products are only created if this is configured in your contract. The integration first checks whether the products from the order already exist in Billit. If not, the integration adds the missing products. The rules for matching products between Mijnwebwinkel and Billit can be found in this FAQ read here.
Regarding VAT, the integration follows the VAT percentage in the order.
Automatically sending invoices
