About Tellbill for WooCommerce
From the official readme · v1.4.2Description
Tellbill is a Swiss invoicing service: QR-bill invoices (ISO 20022), automatic payment reminders, bank reconciliation and credit notes. This plugin connects your WooCommerce shop to your Tellbill account.
What it does
- When an order reaches the trigger status you choose (default: “Processing”), the plugin calls the Tellbill API and creates the matching invoice — with a Swiss QR code — then (optionally) emails it to your customer.
- The Tellbill invoice number is displayed in the orders list and in the order notes.
- Payment sync (optional): when the customer pays the QR-bill, Tellbill notifies WooCommerce through a signed webhook and the order is automatically marked as paid (stock, downloads, etc.).
- Refunds: a WooCommerce refund automatically creates the matching credit note in Tellbill (VAT included; full refund = full credit note).
- Duplicate-safe: each order is sent with a unique identifier (
external_id = "wc_<order id>"). If the same order is sent twice (double status change, network retry), Tellbill returns the existing invoice instead of creating a duplicate.
Requirements: a Tellbill account (https://tellbill.ch) and an API key.
Which trigger status should you choose?
- Invoice-based selling (very common in Switzerland: the customer receives the goods, then pays within X days): trigger “Processing” or “Completed”. The invoice carries your payment term; if the customer is late, Tellbill sends reminders automatically.
- Prepayment by QR-bill (the customer pays before you ship): enable the “Direct bank transfer” gateway so the order lands in “On hold”, and set the trigger to “On hold”. The customer receives the QR-bill, pays, then you ship.
- Paid online (card at checkout): trigger “Processing” — the Tellbill invoice then serves as a receipt and accounting record.
External services
This plugin communicates with the Tellbill API (https://tellbill.ch) — the invoicing service it connects to; that is its sole purpose. No data is sent until you configure your API key.
Data transmitted to the Tellbill API (https://tellbill.ch/api/v1, or the URL you configure):
- When an invoice is created (order reaching the trigger status): the customer’s billing details (name, email, address), the order lines (item names, quantities, prices) and the order number.
- When a refund is issued: the refunded amount and the refund reason.
- When you click “Test connection”: only your API key is transmitted (as a header).
This data is required to issue the invoices. It is processed by Tellbill according to its terms of service and privacy policy:
- Terms of service: https://tellbill.ch/cgu
- Privacy policy: https://tellbill.ch/confidentialite
Translations
The plugin ships with German (de_DE, de_CH), Italian (it_IT) and English (en_US, en_GB) translations — the four Swiss business languages are covered out of the box. Source strings are in French (built for the Swiss market). A .pot template is bundled in /languages for any additional language.
Installation
- Upload the plugin through Plugins → Add New → Upload Plugin (or copy the folder to
wp-content/plugins/), then activate it. - Go to WooCommerce → Settings → “Tellbill” tab.
- Paste your Tellbill API key (Tellbill panel → Settings → API & integrations).
- Pick the trigger status, the payment term and the default VAT rate, then use the “Test connection” button.
Payment sync (optional): in your Tellbill panel → Webhooks, create an endpoint pointing to the URL shown in the plugin settings (https://your-site/wp-json/tellbill/v1/webhook), subscribed to the invoice.paid event. Then paste the signing secret shown by Tellbill into the plugin settings. Requests are verified with an HMAC-SHA256 signature and a 5-minute anti-replay window; while no secret is configured, the endpoint rejects all requests.
Frequently asked questions
Do I need a Tellbill account?
Yes. The plugin is a connector: invoices are created, sent and reconciled by Tellbill. You can create an account on https://tellbill.ch.
In which languages are the invoices sent?
Tellbill issues the invoice PDF and the email in the customer’s language (French, German, Italian or English), configurable per customer in your Tellbill panel.
What happens if the API is unreachable when an order comes in?
The plugin adds a note to the order with the error message. You can re-trigger the invoice by setting the order status again — thanks to the external_id, no duplicate will ever be created.
Changelog
1.4.2

wp_enqueue_script/wp_enqueue_stylefunctions (withwp_localize_scriptfor the nonce and labels) instead of being printed inline. - Translations are now delivered through WordPress.org language packs (translate.wordpress.org) and loaded automatically; the plugin no longer ships or manually loads bundled translation files.
1.4.1
