1.Introduction

This is the manual for the integration between Opencart and e-Boekhouden.

This integration ensures that orders from the Opencart webshop are automatically processed to mutations or invoices in e-Boekhouden. Because the orders arrive directly in the retailer's accounting system, this saves time on the financial administration.

Please pay special attention to the following
  1. This integration is a financial integration. It is not a logistics integration. It is not suitable for updating customers in e-Boekhouden, printing packing slips, or synchronizing products/inventory.
  2. 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.
  3. Tip: Other customers using this integration found the tips in the FAQ for Opencart and in the FAQ for e-Boekhouden.

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.

Cancel integration
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

A order from the Opencart webshop is processed to an e-Boekhouden mutation or invoice. By default, the integration processes to mutations. The option invoices can be requested via webcare@webwinkelfacturen.nl.

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.

Pre-check orders
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 e-Boekhouden for the VAT in each line.
  • It is checked whether the order has not already been processed.

Processing orders
Processing a Opencart order to e-Boekhouden takes place in three steps:
  1. The integration first checks if the debtor is already present in the accounting system. If not, the integration creates the debtor in e-Boekhouden. For a new debtor, we must provide a Code field. This becomes the debtor number in e-Boekhouden. We use the same logic here as e-Boekhouden. Matching of debtors between Opencart and e-Boekhouden is based on email address.
  2. Products With the invoices option, the integration uses the SKU in the invoice lines. If this product is not present in e-Boekhouden, e-Boekhouden will reject the invoice or post it to a random product. Unfortunately, the integration cannot create new products in e-Boekhouden.
  3. The e-Boekhouden transaction (mutation, invoice) is created and processed.

Post-check
After the order has been forwarded and a success message from e-Boekhouden has been received, the order is marked as handled. The Opencart order appears at the Reporting tab on the dashboard.

If e-Boekhouden 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.

When forwarding the payment, the payment is also registered so that it cannot be processed again. Payments can also be reviewed via the dashboard.

Data
Information about the data that is processed can be found in the section Day-to-day: To e-Boekhouden 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: e-Boekhouden codes

Registrations from March 14, 2025

To establish the integration with e-Boekhouden, you need an API token. You can find this API token via Administration > Connections > API > e-Boekhouden API > Next. We recommend entering a clear name and an end date one year in the future. Please note that after this end date, you will need to re-establish the connection with the integration.

Registrations before March 14, 2025

To establish the integration with e-Boekhouden.nl, special codes are required. These are:
- username
- Security code 1
- Security code 2

Read more Required eBoekhouden.nl ....
Read less Required eBoekhouden.nl ....
The username is the username you use to log in. You can find the security code in the Settings. Go to Administration > Settings > Webshop Invoices. You will then see the two security codes listed. You enter these codes in the next step.

 

5.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 OpenCart webshop. Through this step, you authorize the integration to read the data from your webshop.
2. Establishing the connection with e-Boekhouden. This authorizes the integration to write transactions to your e-Boekhouden administration and read information.
3. Configuring additional data, such as the VAT settings.

Read more Installation ....Read less Installation ....

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 OpenCart webshop:
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.

e-Boekhouden Authentication
The red dot and the red Connect button for e-Boekhouden on the Configuration screen indicate that the connection with e-Boekhouden is not yet valid. To activate the connection, click the red Connect button. You will then see a screen containing fields for a username and two security codes. Here, you enter the username and the two security codes you determined in the previous section.

Invoice layout
For e-Boekhouden invoices, an invoice template must be provided. Unfortunately, the integration cannot retrieve the invoice templates in the e-Boekhouden administration. Therefore, the integration uses the name 'Invoice template' as default. If you want to use a different invoice template, you can enter the name of the template when clicking Edit.

Configure VAT rates and general ledger accounts
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 e-Boekhouden. You can always make changes by clicking the blue 'Edit' button and selecting an option from the drop-down menus.

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.

OSS settings
If you are dealing with OSS - new regulations as of July 1, 2021 - it can be configured as follows.

If you use the NL VAT rates, the following remains applicable:
- in the column VAT Code the VAT code with the relevant percentage
- in the column revenue account a revenue account for the net revenue, the payment and shipping costs
- the VAT account column has no function in this case

If you calculate with VAT percentages of the country of delivery in the webshop, please fill in the following:
Per EU country, except NL
- in the column VAT code the VAT code VAT_OSS
- in the VAT account column, a Balance Sheet account for the VAT to be paid in the respective country
- in the column revenue account a revenue account for the net revenue, the payment and shipping costs

Only when using VAT code VAT_OSS, the entry will take place based on the configured VAT account in the Configuration. For other codes, the VAT account is determined in e-boekhouden based on the code.

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.

Configure payment methods
You can create a link here between the payment methods in the webshop and a fixed debtor in your e-Boekhouden 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 e-Boekhouden for an ICP order.

This option is only available when processing to Invoices.

6.Day-to-day: From OpenCart

In this section, we show how we retrieve the orders from Opencart

Processing schedule: New orders from your webshop are retrieved at least once per hour. In addition, every night the orders that were previously retrieved and not yet forwarded to your accounting system are reviewed. An order is processed depending on the status of that order. You can use the dashboard, tab Configuration, set at which statuses orders should be processed.

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 e-Boekhouden.



VAT calculation: The VAT setup of OpenCart is complex and the work of specialists. For OpenCart VAT, the geozone IDs, tax rules, and tax rates must be correctly configured, especially if you deliver to multiple countries. Unfortunately, we do not provide support for the VAT setup of the OpenCart webshop.

7.Day-to-day: To e-Boekhouden

Below is the creation of new transactions in e-Boekhouden - invoices or mutations - detailed at field level.

Creating invoices / sales transactions
The orders from Opencart are imported into e-Boekhouden as mutations or invoices. For each order, the VAT and ledger account are provided as configured during the installation of the integration.

When creating an OSS invoice or mutation in e-Boekhouden, for each line in the Opencart order two lines appear in the e-Boekhouden mutation / invoice. The first line in the e-Boekhouden mutation / invoice contains the amount excl VAT and the second line the VAT amount. The first line is posted to a revenue account, the second line to a VAT account. The revenue and VAT accounts can be configured via the Configuration tab of the dashboard.

When creating invoices or mutations, descriptions and invoice numbers can be adjusted. Below are the options for creating invoices and mutations in e-Boekhouden. When creating invoices, new debtors may be added to e-Boekhouden.

Please note: When creating mutations, the integration provides a sales number. If a mutation with that number already exists, the existing mutation will be overwritten. Therefore, always ensure that sales numbers are unique, especially if you have multiple integrations feeding into a single e-Boekhouden account.

If your integration was installed after March 14, 2025, and the integration processes to Invoices, these are invoices without a corresponding mutation. We can change this to Invoices with a corresponding mutation. In that case, the invoice can no longer be modified in e-Boekhouden.

Creating new debtors
When creating a mutation or invoice in e-Boekhouden, the code of the relation in e-Boekhouden is used. The integration first checks if the debtor is already present in e-Boekhouden. If so, the integration will use the relation code of this existing e-Boekhouden debtor. If not, the integration creates the debtor in e-Boekhouden.

The integration creates a RelationCode for the new e-Boekhouden debtor. The procedure is the same as if you were to create the mutation or invoice in e-Boekhouden yourself. The method performed by the integration is:
1. Determine the company name and the name of the debtor. For the debtor's name, the first name is appended to the last name.
2. Determine whether the company name or personal name of the debtor is used as the base name. If the company name is present, this becomes the base name. Otherwise, the first plus last name.
3. Take at most the first 10 characters of the base name
4. Determine if the base name occurs more than once in e-Boekhouden. If so, it will have one or more sequence numbers. Determine the first available sequence number and append this to the base name.

Example: If the company name is empty and the name is Klaartje Pietersen, the base name becomes KlaartjePietersen. We take the first 10 characters of this. This results in KlaartjePi. If this already occurs 5 times and the highest is KlaartjePi4, the debtor code becomes KlaartjePi5.

Matching between and e-Boekhouden for debtors is based on the email address.

Please note: The integration will never modify debtors in e-Boekhouden. The email address field is used for matching debtors. For integrations started before October 28, 2023, that process to e-Boekhouden mutations, we provide the debtor data within the mutation, and e-Boekhouden determines the debtor code itself.

Create products
Unfortunately, the integration cannot create new products in e-Boekhouden through the e-Boekhouden connection possibilities.
