Messaging – send invoice by email

The Messaging tab automatically emails the PrestaShop invoice PDF to the customer when a Cdiscount / Octopia order reaches a chosen status.

Only orders from the Cdiscount module (module = cdiscount).
The order must already have a PrestaShop invoice number.

1. Enable

Module configuration → Messaging → Send invoice by email:

1. Active → Yes

(Activate invoice per email automation. The module will send the email to the customers with the invoice as an attached document (PDF))

2. Save

2. Orders Statuses (trigger)

Orders Statuses: pick the PrestaShop state that triggers sending
(Choose the order status which will trigger the invoice sending).

Only eligible states are listed:
Only the eligible states are shown (email set to off, invoice to on)

→ in PrestaShop: invoice = Yes, native email = No (avoids a double send).

Example: a dedicated “Cdiscount invoice” status with PrestaShop mail disabled.

3. Choose Mail Template

Select the template from modules/cdiscount/mails/{language}/
(File template which will be used to announce the invoice. / You can add or edit files from the modules/cdiscount/mail directory).

The subject includes the marketplace order ID.

4. Additionnal File (optional, PS ≥ 1.5)

Extra PDF attachment (T&Cs, etc.) from modules/cdiscount/pdf/
(Additionnal PDF file to send as attachment…).

If the list is empty: put the PDF in that folder.

5. Customer email (Settings)

Settings → Marketplace customers → Customer Email:

• individual customer accounts if needed;
• fallback domain when the encrypted Cdiscount email cannot be retrieved

(Please choose a domain name for the customer's email addresses…).

Without a valid address, sending fails.

When it runs

On order status change to the configured state:

1. Cdiscount order;
2. Messaging on + status + template;
3. PrestaShop invoice already generated;
4. email to customer + invoice PDF (+ extra PDF if set).
