GoRoute E-Invoicing for WooCommerce – Peppol invoices, credit notes, delivery status

GoRoute E-Invoicing connects your WooCommerce store to GoRoute, a certified Peppol Access Point (POP000991) and an accredited service provider in Oman, Australia and New Zealand. The plugin is not an invoice generator bolted onto someone else’s network: GoRoute is the network access point, so the invoice, its delivery and its delivery status are one service. Live today for businesses registered in Belgium, Germany, the Netherlands, Australia, New Zealand and Oman.

Governments are making structured e-invoices mandatory between businesses. Belgium has required them since 1 January 2026. Oman’s dates are 1 April and 1 October 2027. Germany, Singapore and others are phasing them in. A PDF by email no longer counts. Choose the country your business is registered in, connect once, and every paid order is handled correctly from then on.

Set-up in five steps

A set-up wizard opens on first activation and can be run again at any time: where is your business registered; connect to GoRoute; your business name and identifier, checked in your country’s format; store readiness with each fix beside its row; send a test invoice. Nothing else to configure.

Choose your country, and the rest follows

• The VAT or business-number field at checkout, in your country’s format, checked as the customer types.
• Business versus consumer detection from that one field.
• The right e-invoicing identifier, document format and network for your country.
• A structured e-invoice delivered to the buyer’s e-invoicing system over the Peppol network.
• A credit note for every refund, and for a cancellation, that cites the original invoice.
• Delivery status on the order: being delivered, delivered, or what needs you.
• A PDF and the XML for every document, and the document UUID with a copy control.
• Plain-language errors and a daily digest of anything that needs a person.

You never see UBL, PINT or Peppol. You see an order that was invoiced.

Countries

• Belgium: B2B e-invoicing over Peppol (BIS Billing 3.0), mandatory since 1 January 2026. Belgian VAT number at checkout, checked against VIES and the Peppol network. Consumer sales need no e-invoice and get none.
• Germany: EN 16931 invoices (Peppol BIS Billing 3.0) to business customers over Peppol; German VAT number at checkout, checked against VIES.
• Netherlands: Peppol BIS Billing 3.0 to business customers; Dutch VAT number at checkout, checked against VIES.
• Australia: PINT A-NZ invoices over Peppol; ABN at checkout with its check digit verified; GST.
• New Zealand: PINT A-NZ invoices over Peppol; NZBN at checkout with its check digit verified; GST.
• Oman: Fawtara. Consumers get a simplified tax invoice with the Fawtara QR; businesses a full tax invoice over Peppol; the tax report is filed with the Tax Authority automatically. Everything the plugin did for Oman before 2.0, unchanged.
• Coming: Singapore (once GoRoute generates the PINT SG document InvoiceNow expects), Ireland, Austria, Luxembourg and the Nordics. Countries that route invoices through a national platform instead of Peppol (France, Italy, Poland, Romania) are shown as coming soon and cannot be selected yet.

A country is offered only once GoRoute has delivered a test invoice to a real participant there.

At the checkout

A business customer types their VAT number and company name. The plugin checks the number’s format, an EU number against the VIES register, and then asks the Peppol network whether that business can receive e-invoices and under which identifier. The customer is told how their invoice will arrive before they place the order, and you see the same answer on the order.

Refunds, retries and reports

• Every refund on an invoiced order raises a credit note. Partial refunds credit only the refunded lines. A cancelled order is credited in full by itself.
• A changed buyer on an invoiced order is flagged, and one click credits the invoice and issues a new one to the right buyer.
• The invoice PDF is attached to the order emails and the credit note PDF to the refund emails.
• Duplicate submissions are impossible: a retried or double-clicked order returns the same invoice.
• If GoRoute cannot be reached, the checkout is never blocked; issuing retries in the background.
• A monthly E-Invoice report gives the net, VAT and gross figures for the VAT return, with a CSV export.

Watch it working

A sixteen-minute walkthrough on an Oman store: connecting, a consumer sale with the QR receipt, a business sale delivered over Peppol, a refund with its credit note, and where every document lands on the dashboard. A Belgian store works the same way without the consumer receipt.

Before the first invoice

A Store readiness panel checks what a truthful invoice depends on in your country: the country chosen, a connection to GoRoute, your identifier registered on the network, taxes on with your country’s standard rate, the store address in your country, and prices in your currency with the right decimals. Each red row has its fix beside it.

Orders placed by AI agents

Shopping agents now place orders through the Universal Commerce Protocol (UCP) and the Agentic Commerce Protocol (ACP). Neither order carries an invoice, and neither puts the buyer’s tax identity where WooCommerce reads it, so a business order from an agent would arrive as a consumer sale. The plugin recognises an agent order (the Stripe gateway’s agentic checkout, WooCommerce’s experimental Agentic Checkout, the UCP/ACP Agent plugin, or any layer that says so through a filter), takes the buyer’s registered name and tax identifier the agent supplied under the ai.goroute.einvoice extension, and issues the same business invoice a customer typing a VAT number at checkout would get. The order then carries an einvoice object (status, document type, number, how it was delivered) for the agent to read. Specification: https://goroute.ai/ucp/einvoice.json. Ordinary orders are untouched.

What this plugin does not claim

It generates and transmits structured e-invoices for the countries listed above and validates them against the applicable Peppol rules. Whether a given business is inside a mandate, and what else that mandate asks of it, is for the business and its adviser to confirm.

Requires a GoRoute account

The plugin is free. A GoRoute account is what issues the documents, and a new account starts on the Free plan: 50 invoices a month with every feature and no card. When the store outgrows it, the settings page shows the usage and the paid plans (Starter $19, Growth $49, Business $99, Agency $249 a month, in US dollars); choosing one opens Stripe Checkout run by GoRoute and brings you straight back. Paid plans are never stopped at their allowance. Press “Connect to GoRoute” in the set-up to create the account.

External Services

This plugin connects to the GoRoute e-invoicing API at https://goroute.ai to issue documents. It is useless without it, by design: the compliance rules, validation and delivery live on the platform, so a rule change in your country reaches every store the same day with no plugin update.

What is sent, and when

• On each paid order and each refund: the order’s line items (name, quantity, net price, tax rate and category, SKU), totals, currency, your legal seller name and VAT number, and the customer’s billing name, company, address, email and VAT number where given.
• On “Connect to GoRoute”: your store’s address and name, so GoRoute can issue the store its own key.
• On “Test connection”, at checkout when a VAT number is typed, and on “Look up”: a single authenticated read to verify the key or to ask whether a VAT number is on the network.
• For an EU store, a VAT number typed at checkout is also checked against the European Commission’s VIES service (https://ec.europa.eu/taxation_customs/vies/), which receives the country code and number only.
• On deactivation, only if you press Send in the short “why are you leaving” box: your answer, an email address if you give one, this site’s address, the country and plugin version, by your site’s own mail to [email protected]. Skip sends nothing.
• Nothing is sent at any other time, and nothing is sent by a store that has not been connected.

What comes back

The invoice number, the document UUID, delivery status for business documents, PDFs and XML on request, and for Oman the verification URL and the QR code as an inline image stored on the order. The plugin loads no remote scripts, styles or images from any third party; the only outbound calls are the API calls above.

Service provider: GoRoute (ClayDesk LLC / Union Digital Technologies SPC). Terms: https://goroute.ai/terms.html. Privacy: https://goroute.ai/privacy.html.

Opt-in only, both unticked by default, on the first set-up step:

• Help me set up sends one message to GoRoute (https://goroute.ai, privacy policy https://goroute.ai/privacy.html) with your site address, the email of the signed-in administrator, the plugin, WordPress, WooCommerce and PHP versions and the country you chose, so a GoRoute person can write back. It is sent once, when you tick the box.
• Anonymous usage and error reports send small events to the same GoRoute API when the plugin is activated, when a set-up step is completed, weekly, and when one of the plugin’s own calls to GoRoute fails: the plugin, WordPress, WooCommerce and PHP versions, the country, the step or the error code, and a one-way hash of your site address. Never the address itself, never a name, order or customer. Switch it off at any time under GoRoute E-Invoicing settings.

Every call the plugin makes to GoRoute carries a User-Agent header naming the plugin version, as any HTTP client does.
