Descripción

Keep your WooCommerce store compliant with Peppol e-invoicing — mandatory for B2B in Belgium (Jan 2026) and rolling out across the EU. This plugin connects your store to GestOO, your Belgian invoicing and accounting platform, so you can create official invoices and send them on the Peppol network without complex setup.

Simple: Configure once (API token + trigger status). Orders automatically create invoices in GestOO and can be sent via Peppol.
Compliant: GestOO uses a certified Peppol Access Point — invoices meet B2B e-invoicing requirements.
Transparent: On each order, see sync status, invoice number, Peppol delivery status, and quick links to open in GestOO or retry.
Transparent pricing: €99/year includes 50 documents/month — no hidden fees. See gestoo.be/tarifs for full details.
No lock-in: Official invoicing stays in GestOO. WooCommerce remains your store; GestOO remains your invoicing hub.

Requirements:

WordPress 6.0+
WooCommerce 7.0+
PHP 7.4+
A GestOO account with the WooCommerce module enabled and an API token

Without a valid API token, plugin settings remain disabled and a clear link to create a GestOO account is shown.

How it works

When an order reaches a trigger status (e.g. Completed), the plugin sends order data to GestOO.
GestOO creates the invoice and can send it via Peppol (after your account is validated).
On the order edit screen, a “Peppol Invoice” box shows: sync status, invoice number, Peppol status, and links to open the invoice in GestOO or retry actions.

Preguntas frecuentes

Is this compliant with Belgium’s 2026 B2B e-invoicing mandate?: Yes. When used with GestOO, invoices are created in the required Peppol BIS Billing 3.0 format and sent via a certified Peppol Access Point. This meets the mandatory B2B e-invoicing requirements for Belgian VAT-registered businesses.
What does it cost?: GestOO WooCommerce + Peppol: €99/year with 50 documents (invoices) per month included. No hidden fees. See gestoo.be/tarifs for full pricing and volume tiers.
Do I need a GestOO account?: Yes. Invoicing and Peppol are handled by GestOO. This plugin only connects your store to GestOO. Create an account at gestoo.be and get an API token from your GestOO dashboard.
Why are settings disabled?: Settings are disabled until the connection test succeeds (valid API token). This avoids sending data to an invalid or missing backend.
Who handles Peppol compliance?: GestOO uses a certified Peppol Access Point to send invoices on the Peppol network. This plugin does not implement Peppol in WordPress.

Registro de cambios

1.0.5

Fix automatic invoice sync: order status from WooCommerce has no wc- prefix in the status-changed hook, but trigger settings use keys like wc-completed. Triggers now match correctly so invoices are created when the order reaches a selected status.

1.0.4

GestOO sending mode alignment: the send API follows your GestOO account setting (GestOO Settings Modules Invoicing Sends tab): email only, Peppol only, email + Peppol, or disabled. Requires a current GestOO backend; if sending is disabled in GestOO, no invoice is sent automatically from the plugin.
Clearer admin errors: failed sends show a readable message, including the current GestOO sending mode and where to change it in GestOO.
French translations updated for the new strings (fr_FR .po).

1.0.3

Payload now includes payment_method_title (human-readable payment method). When an order is paid, GestOO invoice displays “Commande WooCommerce payée via [method] le [date]” instead of standard payment conditions.

1.0.2

Customer payload now includes billing phone. GestOO creates/updates a contact with name, email, and phone when creating invoices from WooCommerce orders.
VAT number: GestOO stores country code (ISO) and digits separately for PEPPOL compliance.

1.0.1

VAT number normalization: extract country code and digits only (no spaces, dots, hyphens) before sending to GestOO. Fixes PEPPOL rejection when WooCommerce stores “BE 056.776.111” or “056.776.111”.
Detailed Peppol error messages (e.g. mod97 invalid) now propagated to WooCommerce order meta and displayed in meta box and event log modal.
Setting “Normalize VAT for PEPPOL” now applies to all EU countries, not just Belgium.

1.0.0

1.0 stable release. Production-ready WooCommerce to GestOO connector for Peppol e-invoicing.
Retry button: full sync + Peppol send when status is Pending, Rejected, or Error. Client data (VAT, address, email) updated from WooCommerce when retrying.
Sync button in orders list for Pending/Rejected/Error; no Sync when already Delivered (use Retry to resend).
Peppol error messages: full validation messages (e.g. PEPPOL-COMMON-R043) stored and displayed when send is rejected.
HPOS compatible. Belgium 2026 B2B e-invoicing compliant.

0.9.0

Retry button when Peppol status is Rejected: allows re-attempting send after tenant configuration or VAT correction (calls send-peppol API).
Refresh status now only reads status; use Retry to re-evaluate and resend.

0.8.0

Dates facture : created_at (date création commande) et paid_at (date paiement) transmises à GestOO. Factures non payées marquées comme non soldées.
Icônes cohérentes : Sync (dashicons-update) et Ouvrir dans GestOO (dashicons-external) dans la liste des commandes.
Spinner WordPress pendant les actions AJAX (Generate invoice, Sync, Send Peppol, Refresh).
Rafraîchissement de la colonne Peppol sans rechargement après Sync réussi.

0.7.0

Fixed Test payload result not visible (ID conflict between API token and payload result div).
Improved mapping descriptions: explicit note that keys are tested in order and first non-empty value wins.

0.6.0

Reorganized settings page into tabs: General settings | Diagnostic | Test order.
Fixed Diagnostic and Test payload buttons (were rendered as text inputs; now use proper WooCommerce filter woocommerce_generate_*_html).
Clear separation of concerns: connection/mapping in General, diagnostic in Diagnostic tab, payload test in Test order tab.

0.5.0

Added “Test order” section in settings: select an order and run a dry-run payload test without creating an invoice.
Payload test displays VAT number, language, vat_rate per line, field status (✓/✗), and warnings.
Toggle to show full JSON payload for debugging.
Banner “Settings modified. Test an order to validate.” shown after saving settings, cleared after a successful test.

0.4.0

Added smart sync/retry button in the orders list: creates invoice if missing, refreshes Peppol status if already sent.

Stored error log (up to 20 entries) in order meta for diagnostics.
