- UBL (Universal Business Language) invoices: Compatible with governments and business customers
- Automatic sending via Peppol: Standardized & legally valid
- B2B ready: Perfect for businesses selling to other companies or government entities
- EU compliance: Ready for Peppol e-invoicing requirements (mandatory from 2026 in many EU countries)
Why Choose SendPol?
From 2026, Peppol e-invoicing will become mandatory in more and more European countries, especially for businesses and government contracts. With SendPol, you're ready for compliance without complex setups or high development costs.

Step-by-step in under 3 minutes
Start in test mode
By default, every new webshop is in test mode. Documents are validated and visible in your SendPol dashboard, but they are not forwarded to the Peppol network. This lets you safely test your workflow before any invoice goes live.
When you are ready for production, switch off test mode in your webshop settings under MyAccount.

PrestaShop Settings
Rounding Settings
It is important that rounding in PrestaShop is configured on the total rather than line by line. Applying VAT line by line causes discrepancies of several cents, which creates issues with Peppol.
Rounding Rule
You can choose between 6 different ways to round prices. 'Round to the nearest higher value' is the recommended behavior.
Rounding Type
You can choose when to round prices: for each item, each line or the total (of an invoice, for example).
Configuration Steps
Follow these steps to configure rounding settings in PrestaShop
Go to your PrestaShop admin dashboard
Navigate to Shop Parameters > General > Rounding
Set the 'Rounding Rule' to 'Round to the nearest higher value'
Set the 'Rounding Type' to 'Round the total'
Click 'Save' to save the settings

Status Mapper
About the Status Mapper
With the status mapper, you can determine when a PrestaShop order should automatically generate and send a Peppol invoice. You choose which PrestaShop order status triggers the invoice sending.
Key Features
- Flexible status mapping: Choose which PrestaShop status triggers the invoice
- Multiple statuses possible: Configure different statuses for different scenarios
- Automatic processing: Once an order reaches the chosen status, the invoice is automatically generated and sent
- Custom workflow: Adapt the module to your specific order processing workflow
- Map multiple statuses: Set up different statuses for different types of orders or customers
Configure Status Mapper
Follow these steps to set up the status mapper
Go to the SendPol module configuration in your PrestaShop admin
Navigate to the 'Status Mapper' or 'Status Mapping' section
Select the PrestaShop order status that should trigger sending Peppol invoices
Common statuses are: 'Shipped', 'Paid', 'Processing', or a custom status
Optional: Configure multiple statuses for different scenarios (for example, different statuses for B2B and B2C)
Save the settings - the module will now automatically send invoices when orders reach this status
Tip: Tip: Choose a status that fits your workflow. For example 'Shipped' if you want to send invoices after shipping, or 'Paid' if you want to send invoices after payment. You can also configure multiple statuses for different workflows.
Status mapping examples
Practical examples of how you can use the status mapper for different workflows

Invoices after payment
