Singapore InvoiceNow (Peppol) E-Invoicing for WooCommerce is a build-to-order plugin that ECOSIRE designs, builds, installs, and supports directly on your WordPress/WooCommerce site. It is not an instant WordPress.org or WooCommerce.com download — you buy the build, and our engineers deploy and configure it for your specific store, GST registration, and chosen IMDA-accredited Access Point.
Generates Peppol BIS Billing 3.0 UBL XML from each WooCommerce order, mapped to IMDA InvoiceNow requirements
IRAS 5-corner GST transmission model: invoice flows C1→C2→C3→C4 plus the GST data relay to IRAS
Routes every document through your chosen IMDA-accredited Access Point / IRSP (C2→C3 sending)
SGD totals, tax-inclusive/exclusive handling, and GST tax mapping (Standard-Rated, Zero-Rated, Exempt) with rounding control
Peppol Participant lookup and SMP validation before sending, so invoices aren't dispatched to unreachable recipients
Sender identity configuration: UEN, Peppol Participant ID (0195 scheme), and GST registration number
Once live, the plugin hooks into the WooCommerce order lifecycle (via actions like woocommerce_order_status_completed and woocommerce_payment_complete) to generate a compliant Peppol BIS Billing 3.0 UBL XML document for each qualifying order. It maps your SGD line items, GST tax codes (Standard-Rated, Zero-Rated, Exempt), shipping, and rounding into the correct UBL fields, then transmits the invoice through your IMDA Access Point (C2→C3) so it reaches your customer's Access Point under the 4-corner Peppol model — extended to the IRAS 5-corner model, where the required GST data is also relayed to IRAS for InvoiceNow GST reporting.
Built for HPOS / custom order tables as well as legacy post-based orders, it stores transmission status, Peppol Participant IDs, and document references against each order. A WP-Cron worker handles retries and status polling so a transient Access Point outage never silently drops an invoice. Admins manage everything from a dedicated wp-admin settings screen: endpoint credentials, sender UEN/Peppol ID, participant lookup and validation (SMP), GST treatment defaults, and per-order resend.
Because it is build-to-order, we tailor field mappings, number formats, and tax logic to how your store actually sells — multi-rate carts, deposits, B2B vs B2C, WPML or multisite setups included. Every engagement ships with installation, a walkthrough, and a defined support window.
A GST-registered SG merchant adopting IMDA InvoiceNow who needs every WooCommerce order issued as a compliant Peppol e-invoice without retyping into a separate portal.
A business-to-business seller whose customers demand Peppol-deliverable invoices to their own Access Points, and who needs participant lookup and reliable C2→C3 routing.
The person responsible for GST reporting who wants invoice data flowing to IRAS via the 5-corner model with an auditable per-order transmission log, not manual reconciliation.

No. This is a build-to-order plugin. ECOSIRE builds it for your specific store, GST registration, and chosen IMDA Access Point, then installs and configures it on your WordPress/WooCommerce site. There is no public WordPress.org or WooCommerce.com download — the value is in the tailored build, deployment, and validation.
A standard build is typically delivered within about 2 to 3 weeks from when we have your requirements and Access Point credentials. We build on staging first, run test transmissions against the Peppol network, then cut over to production. Complex tax logic, multisite, or WPML setups can extend the timeline, and we confirm exact dates during scoping.
Every build includes a defined post-launch support window covering bug fixes and compatibility updates for new WooCommerce and WordPress releases. We also maintain the plugin against Peppol BIS and IMDA InvoiceNow specification changes. Extended or ongoing maintenance can be arranged so your e-invoicing keeps working as the network and your store evolve.
Yes. The plugin generates and submits compliant invoices, but actual transmission onto the Peppol network goes through an IMDA-accredited Access Point (IRSP) that you hold an account with. We integrate the plugin with your Access Point's API and credentials. If you don't have one yet, we can guide you on selecting one as part of the engagement.
Yes. It is built for WooCommerce High-Performance Order Storage (custom order tables) as well as legacy post-based orders, and we map your existing SGD pricing, GST tax classes, and rounding during the build. WPML and multisite configurations are supported and configured to match how your store is structured.
