This is build-to-order, not a marketplace download. After we confirm scope — your catalog size, payment methods, tax rules, printer, and whether you use HPOS, WPML, or multisite — ECOSIRE builds and configures the plugin, tests it on a staging copy of your site, then deploys to production with you. Typical delivery is a few weeks depending on complexity. You get a working register installed on your own WordPress, not a ZIP you have to wire up yourself.

The sale is written immediately to a local IndexedDB queue in the browser and a receipt prints offline from a cached template, so the customer is served with zero delay. Nothing is lost if the tab closes or the device reboots — the queue persists on disk. When connectivity returns, a background sync worker replays each queued sale against the WooCommerce REST API to create the real order (into HPOS tables or the legacy shop_order type), and a WP-Cron fallback retries anything still pending.

On reconnect the plugin runs an inventory conflict-resolution pass that compares queued sales against current _stock meta and against what other registers synced. Instead of silently overwriting stock, conflicts (such as the same last unit sold twice) are surfaced for review according to the policy you choose in the WooCommerce settings panel — server-authoritative, last-write-wins, or hold-for-review. You decide how aggressive reconciliation is for your business.

Yes, that's the point of building to order. We wire the POS into your live store: it creates orders through your configured payment methods, respects your tax classes, fires your woocommerce_thankyou and order-status hooks so email/invoicing/fulfillment automations keep running, and writes to HPOS custom order tables when you have them enabled. WPML and WooCommerce multisite compatibility are supported as optional scope and tested against your specific configuration.

Every build includes a post-launch support window during which ECOSIRE fixes issues, tunes the sync and conflict behavior to your real-world usage, and keeps the plugin compatible with WordPress and WooCommerce core updates. Because you own the source on your server, there's no per-seat license lock-in. Extended support and maintenance can be arranged after the initial window, and we can add registers, printers, or new sync rules as your operation grows.
