Typical delivery is around one working week from the point we have your GSP/ASP sandbox credentials, GSTIN details and catalogue. We build against your store, test in the IRP sandbox with sample orders, deploy to your staging site for sign-off, then switch to production. Timelines move with scope add-ons like WPML invoices, multisite or multi-GSTIN setups — we confirm a firm date in writing before starting.

Every build includes a defined post-launch support window for bug fixes and configuration help, plus compliance updates when the government changes the IRP JSON schema or e-way bill rules. Because we install and own the deployment with you, we can patch directly on your site. After the included window, ongoing maintenance is available as an optional retainer.

Yes. E-invoicing requires a GST Suvidha Provider / ASP relationship and IRP API credentials registered to your GSTIN — the plugin authenticates as you. We work with your chosen GSP, integrate against their sandbox first, and help you move to production. We do not resell IRP access, so your data and credentials stay yours.

Yes. The plugin is built for WooCommerce High-Performance Order Storage (custom order tables) as well as the legacy post-meta model, and it hooks into standard order-status actions rather than overriding your theme. During the build we test it against your live plugin stack on staging and resolve any conflicts before going to production.

Generation never blocks the customer's checkout. Failed or pending submissions go into a WP-Cron retry queue with back-off, and every attempt is recorded in an admin audit log. You can also re-trigger IRN or e-way bill generation manually from the order screen, so nothing is silently lost during government downtime.

Yes. IRNs can be cancelled within the government's 24-hour window directly from the WooCommerce order screen, and the plugin supports credit-note (CDN) documents for returns and refunds so your e-invoice records stay consistent with your accounting.
