Download the plugin from WooCommerce and upload it to your WooCommerce platform. 2. [Activate your Billie account](https://www.billie.io/onlineshop-registrierung) and configure the plugin. 3. Set up payment methods and invoicing. 4. Test and deploy your new integration. ## FAQ ### Why does my order fail with “Invoice ID not set”? Billie needs your own invoice number when an order is captured, and the plugin does not generate one. It reads the number from PDF Invoices & Packing Slips, Germanized Pro, German Market, or from the invoice field on the order screen. If none of those supplies a number, the capture stops and the order gets a note saying so. Two setups look correct but supply nothing: * **PDF Invoices & Packing Slips** ships with invoice documents switched off. Enable the invoice document under WooCommerce -> PDF Invoices -> Documents -> Invoice. * **Germanized** only has invoicing in the Pro edition. The free edition never creates invoice numbers. You can always enter a number by hand in the Billie box on the order screen. ### Can an order be captured in several parts? No. Each order is captured once, for its full amount, when it reaches the status configured under Authorization & Capture. Partial captures would need a separate invoice number per shipment, and the supported invoicing plugins issue one number per order. ### Can I still change the order amount after checkout? Yes, until the order is captured. Edit the line items as usual and the new total is sent to Billie on save. Increases are re-checked against the buyer’s limit; reductions apply directly. Once the order has been captured the amount is fixed by the invoice. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Billie for WooCommerce” is open source software.

[Browse the code](https://plugins.trac.wordpress.org/browser/billie-for-woocommerce/), check out the [SVN repository](https://plugins.svn.wordpress.org/billie-for-woocommerce/), or subscribe to the [development log](https://plugins.trac.wordpress.org/log/billie-for-woocommerce/) by [RSS](https://plugins.trac.wordpress.org/log/billie-for-woocommerce/?limit=100&mode=stop_on_copy&format=rss). ## Changelog #### 2.4.1 * Fix: The development files .eslintrc and README.md are no longer included in the release package * Update: Minimum requirements raised to WordPress 6.4 and WooCommerce 9.0.0. Older WooCommerce versions could not complete a Billie order: up to 3.4 the checkout failed or rejected the order, up to 3.6 saving a Billie order crashed, and up to 8.x the legacy REST API could still trigger that crash. WooCommerce 9.0 requires WordPress 6.4 * Update: The plugin author is now shown as Billie GmbH, linking to billie.io * Update: Build toolchain upgraded to @wordpress/scripts 36 on Node 24; build tooling moved to devDependencies * Update: Bump build tooling dependencies to patched versions to resolve Dependabot security alerts – none of the affected packages is part of the shipped plugin #### 2.4.0 * Fix: The payment due date shown on the order screen and printed on the invoice PDF ignored the configured payment term and was always 7 days after completion * Fix: A cancelled Billie invoice no longer shows bank details, a due date and a payment reference on the order screen and the invoice PDF – the invoice has been written off, so nothing is payable * Fix: An order cancelled at Billie can no longer be moved back to the capture status, which made the shop show the order as settled while Billie had closed it * Fix: Marking orders complete from the orders list bypassed the invoice-number check, so the capture failed instead of the status change being refused * Fix: A buyer who closes the Billie payment page without completing it is no longer reported to the merchant as a declined payment – Billie cancels the authorisation in that case, which is not a refusal, so the order note now says so and Billie stays available for a new order * Fix: The WooCommerce transaction ID now holds the Billie order reference instead of Billie’s collection IBAN, which put a bank account number into the order header, exports and some emails. Orders created before 2.4.0 keep their stored value * Fix: The Blocks checkout now shows the payment method title configured in the gateway settings, as the classic checkout and the order confirmation already did. Shops with a custom title will see it in the Blocks checkout from this version on * Fix: The Blocks checkout now shows the missing-billing-company warning before submit, as the classic checkout already did, and the warning is translated; it had been hardcoded German for every locale and was never rendered * Fix: The invoice-number hint told merchants to install PDF Invoices while PDF Invoices was installed and enabled but had not created the invoice for that order yet * Fix: 26 merchant-facing messages had no German translation, among them every capture-failure and invoice-number message; one translation was orphaned by a changed source string. The translation template was regenerated and now covers all strings * Fix: German translation misspelled “Rechnung” as “Rechung” in the order note written after a capture * Fix: Order notes described a cancelled Billie order and a cancelled invoice as“ deleted” * Fix: Classic checkout escaped the line breaks it had just generated in the payment description * Fix: PHP 8.4 and newer logged an “Implicitly marking parameter as nullable is deprecated” notice for every API request method, on every page load * Fix: Opening a Billie order in the admin logged a deprecation notice for wc_enqueue_js, removed in favour of wp_add_inline_script * Add: An order note records that cancelling a Billie invoice makes Billie write the outstanding amount off as a credit note * Update: Tested up to WordPress 7.1 and WooCommerce 11.1.2 #### 2.3.0 * Security: Add exit after wp_redirect() to prevent continued execution after redirect * Security: Remove OAuth access token from debug log to prevent credential exposure * Security: Change client_secret admin field to password type to protect credentials in UI * Fix: Checkout logo could not load – the URL was built from the npm package name instead of the plugin slug * Fix: Blocks checkout script was registered without its declared dependencies * Fix: Order screen meta boxes did not appear and the invoice number could not be saved with HPOS enabled * Fix: A completed order whose capture had failed could not be given an invoice number, making a retry impossible * Fix: Saving an order with an empty invoice field discarded a stored invoice number * Fix: Bank transfer details showed the shop name as account owner instead of Billie GmbH * Fix: Declined payments were reported as technical failures, skipping the decline reason handling * Fix: Classic checkout logo pointed at the wrong directory * Add: A failed capture is recorded on the order, shown on the order screen, and retried once an invoice number is supplied * Add: Status changes that would capture are refused on the order screen while no invoice number exists * Add: Sandbox orders use a unique merchant reference so repeated test setups do not collide * Add: Include plugin version in HPP checkout session create payload * Update: Bump axios, webpack and transitive dependencies to patched versions * Update: Tested up to WordPress 7.0.4 and WooCommerce 11.0.1 #### 2.2.0 * Add: Moved all settings to gateway options page * Fix: Better interoperability with other plugins #### 2.1.0 * Fix: Better interoperability with other plugins #### 2.0.1 * Add: Billie is now in the official WooCommerce plugin directory #### 2.0.0 * Add: Migration to Billie API version 2.0 ## Meta * Version **2.4.1** * Last updated **2 weeks ago** * Active installations **30+** * WordPress version ** 6.4 or higher ** * Tested up to **7.1.3** * PHP version ** 7.4.0 or higher ** * Tags * [payment](https://wordpress.org/plugins/tags/payment/)[woocommerce](https://wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://wordpress.org/plugins/billie-for-woocommerce/advanced/) ## Ratings No reviews have been submitted yet.
