1.Introduction
This is the manual for the integration between Opencart and King/MUIS.
- This integration is a financial integration. It is not a logistics integration. It is not suitable for updating customers in King/MUIS, 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 Opencart and in the FAQ for King/MUIS.
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.
We advise you to revoke the API key and remove the extension from your webshop when uninstalling the integration.
2.How the integration works
New orders from your webshop are retrieved from the webshop at least once per hour. The status of the order is reviewed, and if the order is allowed to be processed, this will occur. If the orders are not yet allowed to be processed, they are checked every night to see if the status has changed and the order can be processed.

At the start of processing an order, we perform a number of checks on the Opencart order:
- It is checked whether the total of the Opencart 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 King/MUIS for the VAT in each line.
- It is checked whether the order has not already been processed.
Processing a Opencart order to King/MUIS happens in three steps:
- It is checked if the customer already exists in King/MUIS. If not, the customer is created. Matching is based on the email address.
- When processing to King/MUIS orders, it is checked whether the products from the Opencart order are already present in King/MUIS. Missing products are created.
- The King/MUIS journal entry or order is created and processed.
After the order has been forwarded and a success message from King/MUIS has been received, the order is marked as handled. The Opencart order appears at the Reporting tab on the dashboard.
If King/MUIS 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 King/MUIS later in the manual.
3.Required: OpenCart Secret key
The integration uses an OpenCart module. You can download this module here:
- cloudinvoiceopencart2.3.zip (OpenCart version 2.3)
- cloudinvoiceopencart3.zip (OpenCart version 3)
You install the extension on your webshop via FTP. You will see the Settings cloudinvoice platform module appear under Modules in your administration panel.
Click on Install to install the module and then on Edit to configure the connection. The license key is the key you received in the registration email. You create the API key to read orders and tax rates from OpenCart yourself. You can think of this API key as a kind of password. Just like with regular passwords, a complex password means you are protecting your data even more. We therefore advise you to enter an API key with a length of at least 15, consisting of numbers, letters, uppercase letters, and the punctuation marks !, *, @, #, (, ) and =. Compose your API key carefully. A good API key makes the connection much more secure. The maximum length of the API key is 64.
4.Required: MUIS environmental code
To integrate with MUIS, you need to request an environment code. MUIS has a manual explaining how to do this. A shortened version follows.
Option 1: The entrepreneur / accountant works with iMUIS Online (SAAS / Web-based)
For the integration, the customer requires a subscription to the iMUIS Online Cloudswitch module for each administration. The accountant can select this for the entrepreneur via User Management. Alternatively, if the entrepreneur does not work through an accountant, the customer can take out a subscription themselves. Subsequently, the entrepreneur generates an environment code via iMUIS Online > Management > My data / Subscription / Connections tab Connections. An environment code is generated when you click on Connect with us as a partner (webwinkelfacturen). Copy this environment code. You will need it to establish the integration between the webshop and MUIS.
Option 2: The entrepreneur / accountant works with iMUIS Business Software (Windows)
In this situation, the entrepreneur must possess an iMUIS Online license, and iMUIS Online must be available on their own server. The entrepreneur generates an environment code via iMUIS Online > Management > My details / Subscription / Connections, Connections tab. An environment code is generated when you click on Connect with us as a partner (webshop invoices). Copy this environment code. You will need it to establish the connection between the webshop and MUIS.
If you use the MUIS orders option, you need to configure the following additional items in MUIS:
- Add item group 29 and enter the revenue account for this item group. New products are automatically added to this item group.
- Add webshop order type, because the orders forwarded to MUIS use this order type.
- Add the Shipping Costs shipping method to the MUIS shipping methods. Ensure that you set a default delivery condition and a preferred order method for the shipping method, and that you link the shipping method to the webshop order type.
5.Installation
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 OpenCart webshop. Through this step, you authorize the integration to read the data from your webshop.
2. Establishing the connection with King/MUIS. This authorizes the integration to write transactions to your King/MUIS administration and read information.
3. Configuring additional data, such as the VAT settings.
Authentication with your OpenCart webshop is done via the API key you created in a previous section. Click the red Connect button next to OpenCart 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 that the API key has a maximum length of 64 and that the license key was not accidentally entered.
Authentication King/MUIS
You click the red Connect button for MUIS Software. You establish the connection with MUIS by entering the environment code. You determined this environment code in the previous section.
To process to King/MUIS financial entries, you can configure a debtors account and journal. To process to King/MUIS orders, a journal is not required.
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 King/MUIS. 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 that 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 King/MUIS 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 King/MUIS for an ICP order.
6.Day-to-day: From OpenCart
In this section, we show how we retrieve the orders from the webshop.
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 King/MUIS.
7.Day-to-day: To MUIS
Creating invoices / sales transactions
The orders from Opencart are imported into King/MUIS as financial entries or orders. For each order, the VAT and general ledger account are provided as configured during the installation of the integration.
When creating entries / orders, new debtors and/or products may be added to King/MUIS.
When processing customer information, it is first checked whether the customer has been processed before. If so, this King/MUIS debtor is used as the debtor for the King/MUIS transaction. If the customer is not yet known, they are added to King/MUIS. Matching is based on email address. Please note: The integration only creates debtors. The integration does not modify debtors.
Product VAT: When creating new products - orders option - in King/MUIS, the integration uses the VAT percentage in the order line. This means that products in ICP and International orders will be created with 0% VAT in King/MUIS. After all, the integration has no other VAT percentage available for the product.
Item group: Products are placed in item group 29. This item group must be present in the MUIS administration.
Dummy products The integration does not work with dummy products because shipping costs and other costs are included as an amount in the header of the order.
Please note: Products are only created in King/MUIS. Products in King/MUIS are never modified.
The integration creates an order or financial entry in King/MUIS, not an invoice. Therefore, the integration cannot ensure that an invoice is automatically sent from King/MUIS.
