Typical delivery is one working week from the kickoff call, depending on catalogue size and how your GSP/IRP access is set up. We confirm scope, your store state rules and HSN mapping first, build against the IRP sandbox, smoke-test on a staging copy of your site, then install and activate on production with you watching. There is no instant marketplace download — you are getting a plugin configured to your store.

You need an active GST registration with your store GSTIN, e-invoicing enabled for your business (mandatory above the current turnover threshold), and access to an IRP-registered GSP or the NIC e-invoice portal API credentials. We also need admin access to your WordPress/WooCommerce site (ideally a staging clone) and your current HSN/SAC list if you have one — if not, we help build it.

Yes. The plugin is built HPOS-aware, so it reads orders from WooCommerce custom order tables and falls back to the legacy posts store on older installs. It hooks into standard WooCommerce order actions, so it is independent of your theme and payment gateways — Razorpay, PayU, Stripe, COD and others all flow the same way once the order is placed.

ECOSIRE supports the plugin after handover. Your build includes a support and maintenance window for bug fixes and IRP/GSP schema changes; when the government updates the e-invoice JSON schema or HSN rules, we ship an update to your site. Ongoing support beyond the initial window is available as a maintenance plan — we will not leave you with an unmaintained plugin when the GSTN changes the spec.

Yes. IRN cancellation is supported within the IRP's 24-hour window, and credit notes are handled as separate documents that reference the original IRN. Both actions are gated by WordPress capabilities, so only roles you authorise can cancel an e-invoice, and every request and IRP response is written to an audit log.

We configure the GSTR-1 (B2B, B2C, HSN summary) and GSTR-3B preparation exports to your accountant's workflow during the build, and validate the figures against a sample filing period before sign-off. The exports are CSV/JSON intended for reconciliation and portal upload — your accountant remains in control of the final return; the plugin removes the re-keying.
