About this plugin
This plugin connects your WooCommerce store to the Pennylane accounting platform. Invoices are
issued by Pennylane, which keeps legal numbering and archiving where they belong — the plugin
never generates an invoice itself.
Create a compliant, legally numbered invoice for any order with a single click: the customer, the
invoice lines, the VAT treatment and the legal mentions are all built for you.
Features:
- One-click invoicing — a “Create invoice” button on every WooCommerce order. The invoice is
created as a draft in Pennylane, then finalized (legal numbering) automatically, and the
Factur-X PDF is retrievable from the order screen.
- Customer sync — companies and individuals are created in Pennylane with their billing
details, and reused on the next order (no duplicates).
- Full VAT and OSS mapping — French rates (20 %, 10 %, 5.5 %, 2.1 %), intra-EU B2B reverse
charge, intra-EU B2C (OSS), exports outside the EU. The right legal mention is written on the
invoice automatically.
- EU VAT number at checkout — an optional VAT number field for business customers (classic
checkout and Checkout Blocks), format-checked, with VIES validation (the official European
Commission service) to secure the exemption.
- B2B VAT exemption at checkout (optional) — charge no VAT to EU businesses with a validated
VAT number: the customer pays the net amount and the invoice carries the legal intra-Community
exemption mention. Off by default (it changes what customers pay, and intra-Community supplies
require filing the EC Sales List — check with your accountant). Whatever you choose, the
invoice always follows the money: if VAT was collected, the invoice is issued with that VAT.
- OSS awareness — tell the plugin whether the store is registered for the EU One-Stop Shop:
under the €10,000 threshold, EU consumers are invoiced with French VAT codes; OSS-registered
stores get destination-country VAT codes.
- SIRET at checkout with auto-fill — French business customers type their SIRET
fr).
- Invoice PDF in My Account — customers can download their invoice from their account,
through a secure endpoint.
- Test mode (dry run) — validate your whole configuration without sending anything to
Pennylane: payloads are built and written to the logs, nothing else.
- Diagnostics tab — token check, live API permission check, decimals check, logs shortcut:
see at a glance why something would not work.
- HPOS and Checkout Blocks compatible — works with the classic checkout and the block-based
checkout, with or without High-Performance Order Storage.
The free plugin is fully functional on its own and is not time-limited.
Need automation? The Pro version adds automatic invoicing on
status change, credit notes on refunds, payment reconciliation, invoice e-mailing to the customer
(your template or Pennylane’s), product mapping, bulk actions with ZIP export, backfill of past
orders, integrity checks, weekly summary, failure alerts and WP-CLI commands.

External services
This plugin communicates with the following third-party services. Nothing is sent without your
configuration or the customer’s own input, and none of these calls carry marketing or tracking
data:
- Pennylane API (https://app.pennylane.com) — the purpose of the plugin. When you create an
invoice, the order data (customer billing details, invoice lines, totals, VAT) is sent to your
own Pennylane account using the API token you configured. Nothing is sent before a token is
configured and an invoice is triggered.

- VIES (European Commission, https://ec.europa.eu) — optional, off by default. When enabled,
the VAT number typed by a business customer at checkout (and only that number) is checked
against the European Commission’s official VAT validation service. Disabled by default: it
only runs after you switch it on in WooCommerce > Pennylane > Invoicing.

- Recherche d’entreprises (https://recherche-entreprises.api.gouv.fr) — optional, off by
default. When enabled, the SIRET typed by the customer (and only that) is sent to
the French government’s public company directory to retrieve the company name and address.
Disabled by default: it only runs after you switch it on in WooCommerce > Pennylane > Invoicing.
