1.Introduction

This is the manual for the integration between Prestashop and Rompslomp.

This integration ensures that orders from Prestashop webshop are automatically processed to invoices in Rompslomp. Because the orders go directly into the online retailer's accounting system, this saves time on financial administration. It is also possible to process payments for the Prestashop orders to Rompslomp. This can be requested via webcare@webwinkelfacturen.nl. Additional costs will be charged for this option.

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 Rompslomp, 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. We can integrate with a Rompslomp package where we can create and read debtors and products. Please take this into account if you are currently using a trial period of Rompslomp.
  4. Tip: Other customers using this integration found the tips in the FAQ for Prestashop and in the FAQ for Rompslomp.

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 in Prestashop when uninstalling the integration.

2.How the integration works

A order from the Prestashop webshop is processed to a Rompslomp invoice.

New orders from your webshop are retrieved at least once per hour. If they have the correct status, they are processed to Rompslomp. You can set the statuses via the dashboard, tab Configuration.

Pre-check orders
At the start of processing an order, we perform a number of checks on the Prestashop order:
  • It is checked whether the total of the Prestashop 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 Rompslomp for the VAT in each line.
  • It is checked whether the order has not already been processed.

Pre-check payments
A payment is processed for every order that has been processed to Rompslomp and that has been paid in Prestashop. It is possible to always process the payment, regardless of the status in Prestashop. This can be requested via webcare@webwinkelfacturen.nl.

Processing orders
Processing a Prestashop order to Rompslomp takes place in three steps:
  1. It is checked if the customer already exists in Rompslomp. If not, the customer is created. Matching is based on the email address.
  2. It is checked whether the products from the Prestashop order are already present in Rompslomp. Missing products are created.
  3. The Rompslomp invoice is created and processed.

Process payments
A payment is processed to Rompslomp by searching for the unpaid invoice in Rompslomp and adding the payment to this invoice. If the unpaid invoice cannot be found, the payment appears at the Errors tab on the dashboard: https://uwkoppeling.webwinkelfacturen.nl. The integration will attempt to find the outstanding invoice for 2 nights and add the payment to it. If the outstanding invoice appears in Rompslomp 1 or 2 days after the payment is made, that is not a problem.

If the invoice appears in Rompslomp at a later time, the payment can still be manually linked to this outstanding invoice via the blue Process button on the dashboard. Because the payment is added to an invoice, it is not possible to process payments if no invoice can be found.

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

If Rompslomp 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 Rompslomp later in the manual.

3.Required: Prestashop API key

To create the API key in your PrestaShop webshop, go to Advanced parameters - Web services via the menu.

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.

Activating the integration consists of three steps:
1. Establishing the connection with the Prestashop webshop. Through this step, you authorize the integration to read the data from your webshop.
2. Establishing the connection with Rompslomp. This authorizes the integration to write transactions to your Rompslomp 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 PrestaShop webshop:
Authentication with your PrestaShop webshop is done via the API key you created in a previous section. Click the red Connect button next to PrestaShop 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 web service is enabled in the PrestaShop webshop.

Rompslomp connection
The connection with Rompslomp runs via OAuth. Make sure you are logged out of Rompslomp before starting the connection. Now click the red Connect button. A login screen for your Rompslomp account will automatically appear. If you log in, you will get a screen asking if you allow the connection. If you confirm this, the connection with Rompslomp will be established.

Administration Rompslomp
After the connection with Rompslomp has been established, the administration for the connection must be set. Only then can other settings be made, such as the VAT rates. Refresh the screen with the arrows next to the Copy button to retrieve the data belonging to the administration. Invoice layout Rompslomp
After selecting the administration and refreshing the screen via the arrows next to the Copy button, an invoice layout can be selected.

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 Rompslomp. 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.

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

Setting up payment methods on clearing accounts
When processing payments, a clearing account of type Payment methods is set in Rompslomp. When setting up the clearing accounts, there is no (longer a) possibility to post to fixed debtors per payment method.

5.Day-to-day: From PrestaShop

In this section, we show how we retrieve the orders from the webshop.

Processing schedule: New orders from your webshop are retrieved and processed to Rompslomp 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. The order status of these orders is checked to determine if they should now 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 Rompslomp.

Please note: Due to the load on our systems, we go back a maximum of 3 months in time to check the status of orders and process them anyway. In addition, the number of orders that can be checked is limited to 300. Therefore, ensure that orders are completed in a timely manner so that the integration can process them and you do not have to manually re-enter them.
Order and invoice numbers: It is possible to provide the Prestashop order or invoice number to the Rompslomp invoices. When processing the invoice number, we only process the number and not the fixed prefix that is sometimes set in Prestashop. Sometimes it is desirable for reconciliation to process the checkout ID or cart ID of the Prestashop, but unfortunately, we cannot read those via the PrestaShop API. Here is an explanation of how other Prestashop webshop owners have solved this: Cart ID Prestashop.

Payments (if activated)
When processing payments, the integration checks every day the Prestashop orders that have been successfully processed to Rompslomp. If the order has been processed, a payment will be created in Rompslomp for this order.

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 validity of the VAT number.

VAT calculation: Prestashop webshops sometimes have VAT rates for all countries with characters from the respective country in the name. For example for Cyprus or Greece. In that case, the integration cannot store the VAT rates. We advise adjusting the names of the VAT rates in the webshop. An explanation can be found here: VAT rates Prestashop.

6.Day-to-day: To Rompslomp

Creating invoices
For orders in Prestashop, invoices can be created in Rompslomp.

Create debtors
When processing customer information, it is first checked whether the customer has been processed before. If so, this Rompslomp debtor is used as the debtor for the Rompslomp transaction. If the customer is not yet known, they are added to Rompslomp. Matching is based on email address.
Please note: The integration only creates debtors. The integration does not modify debtors.

Create products
When processing orders to Rompslomp invoices, the integration first checks whether the products from the order already exist in Rompslomp. The integration then adds missing products to the accounting system. If a product already exists in Rompslomp, the product is not added again. The integration automatically adds the following products in Rompslomp: Shipping costs, Payment costs, Surcharge, Discount and Extra costs.
Rompslomp only accepts SKUs consisting of numbers/letters, without unusual characters.

When creating invoices, the integration uses the VAT percentage as stated in the order from Prestashop. Even if there is a different VAT percentage in the product of Rompslomp.

Create payments
Payments from Prestashop are imported into Rompslomp by adding a payment to the outstanding invoice. This payment consists of the following fields:
  • Amount paid
  • Description: The sales number and the transaction identifier
  • Clearing account, as set in the dashboard
  • Payment date
If no invoice can be found in Rompslomp for the payment, the payment cannot be linked to an outstanding invoice.

Automatically sending invoices
The integration creates the invoice in Rompslomp, but will not automatically send the invoice to the debtor. It is possible to set an invoice layout. This can be done via the dashboard https://uwkoppeling.webwinkelfacturen.nl, tab Configuration.
