Invoices

Saleor version required: 3.10Repository: GitHub

Introduction​

The Invoices app allows you to generate simple PDF invoice files for every order in your store.

Features​

Generates a PDF file when an invoice is requested (in the Dashboard or with an API). Then attaches it to the order.

The invoice shop address can be inherited from the Shop settings or configured manually per channel.

Assumptions & limitations​

  • The PDF template is fixed and can't be changed by the user.
  • The PDF template is in English only.

Permissions​

The App requires MANAGE_ORDERS permission to be able to:

  • Receive the INVOICE_REQUESTED webhook
  • Read order data to generate the invoice
  • Attach the invoice to the order

The staff user configuring the App must have MANAGE_APPS and MANAGE_ORDERS permissions.

Application flow​

The App reacts on a single webhook, and it ends its flow once a PDF file is attached to the order.

See the detailed flow below:

Configuration​

The app allows to configure a shop address per each channel separately.

If the channel is not configured, the app will fetch the Shop address from settings and use it.

Testing​

To verify if the app works:

  1. Ensure the "Invoices" legacy plugin is disabled; otherwise, duplicated invoices can be generated.
  2. Ensure the App is installed and enabled.
  3. Optionally configure the custom address. If the custom address is not configured, fill Shop address in the Dashboard settings.
  4. Find any order in the Dashboard, find the "Invoices" section, and click the "Generate" button.
  5. Wait a couple of seconds and refresh the dashboard.
  6. The invoice should be attached to the order in the "Invoices" section.

Troubleshooting​

  • During development with Saleor running locally, there are file uploading issues; see this issue.

Check Github issues to see up to date list of known issues or to report a new one.

Development​

Env variables​

Apart from common env variables, the Invoice app accepts the following:

  • TEMP_PDF_STORAGE_DIR= - a temp directory where the PDF files will be stored. In Vercel, set /tmp. Add it to .gitignore

Migration from the Invoicing plugin​

The Invoices App covers the functionality of the plugin. In the future, plugins will be deprecated and replaced by apps. To migrate from plugin to app, follow the steps below:

  1. Install the Invoices App from the App Store (Dashboard -> Apps).
  2. Open the installed App.
  3. Verify the default shop billing address. It will be fetched from Shop Settings.
  4. Verify per-channel shop address settings. It will use the default one but can be overridden.
  5. Open a test order in the Dashboard.
  6. Click the "Generate" button in the "Invoices" section.
  7. Wait for two PDF files to generate: one from the plugin and the second from the app. You may need to refresh the page.
  8. Compare generated PDF files, and ensure all required information is available on the app-generated invoice.
  9. Disable the Invoicing plugin.

Differences between the plugin and the app​

  • The invoice name is different. The plugin uses the invoice creation date; the app uses the order creation date.
  • The invoice template is different. The app additionally displays the Seller (shop) address. The shipping is displayed as a line item.
