Can I update a customer's details (VAT, Company Name) and resend a Peppol invoice that was already delivered?
No. Once an e-invoice is successfully transmitted and delivered through the secure Peppol network, it is treated as a finalized, locked financial document. It cannot be recalled, modified, or simply overwritten. If you update a customer's details in your platform, those new details will strictly apply only to new, upcoming invoices generated after the update was made.
If I add a customer's B2B details today, can I use them to send Peppol invoices for their older orders?
Yes, if the invoices haven't been sent previously, this is possible! Our system pulls the customer's data at the exact moment the e-invoice is generated. This means that if you update a customer's profile today, those new details will be applied to all future orders, as well as any previous orders that have not yet been transmitted through the Peppol network.
Why is my checkout extension not displaying even though I added it?
Our app allows you to add a custom block directly to your checkout page, letting you collect crucial B2B business data (like Company Name and VAT) from your customers before they finalize their order. However, if you have added this block and it is not showing up on your live storefront, it is because this specific feature requires two strict conditions to be met:
1. You must be a Shopify Plus merchant: Shopify currently restricts custom checkout extensions exclusively to stores on the Shopify Plus plan.
2. Your Peppol registration must be "Verified": The extension will remain safely hidden from your customers until your Peppol onboarding is completely finished. Please navigate to the Peppol page in your app settings, ensure you have provided valid business data, and verify that your current account status explicitly says "Verified".
I subscribed to the add-on and added the app blocks to my Thank You and Order Status pages, but it is still not asking my customers for their Peppol address. Why?
If you have successfully placed the app blocks but only see fields for "Company Name" and "VAT Number," it is tied directly to your store's current Peppol registration status.
Our app blocks use smart logic to display the right fields at the right time:
Before Verification: Until your own store's Peppol registration is fully completed and marked as Verified in our system, the customer-facing blocks operate in a standard B2B mode. They will safely collect essential billing data (Company Name and VAT number) so you can still generate valid XML e-invoices.
After Verification: Once your Peppol account is officially verified and active, the app blocks will automatically update and begin asking your customers for their specific Peppol Address so you can start routing invoices through the network.
To unlock the Peppol address field for your buyers, please navigate to the Peppol settings in your app dashboard and ensure your business registration is fully submitted and verified.
What is the E-Invoice App Block on the Thank You and Order Status Pages?
To make collecting B2B data as seamless as possible, we offer an E-Invoice App Block that you can easily add directly to your store's post-purchase pages (the Thank You page and the Order Status page).
This block shifts the data-entry work to your buyers, ensuring you get exactly the right billing information for their e-invoices.
How it Works:
Customer Input: Once you add this block to your store, customers reviewing their completed order will see a button labeled "Provide my business details."
Collecting Data: Clicking this button opens a simple form where they can input their official Company Name and VAT Number directly into the order record.
Smart Pre-population: To save your returning B2B buyers time, this block communicates directly with your Shopify Customer profiles. If the buyer has provided these details on a previous order, or if you manually added the B2B data to their profile in your Shopify Admin, the form fields will automatically be pre-populated for them.
Note: If your store is fully Peppol Verified, this block will also expand to ask for their Peppol Address
Which countries can we send Peppol invoices to?
You can send Peppol to any user that is registered on Peppol itself. If you are registered on Peppol and your customer is not, you will not be able to send them a Peppol invoice.
However, if someone buys the order and they are registered on Peppol, and they have provided a valid Peppol data, you will be able to send them a Peppol invoice.
