Offline-First POS for WooCommerce is a custom POS layer that ECOSIRE builds, installs, and supports directly on your existing WordPress + WooCommerce site — not an instant marketplace download. We engineer it around your catalog, tax rules, and hardware, then deliver a working register on your domain.
Local order queue: sales are written to a browser-side IndexedDB store and replayed against the WooCommerce REST API (POST /wp-json/wc/v3/orders) automatically on reconnect
Cached product catalog, prices, and tax classes synced to the device so cashiers can search and build carts with no connection
Inventory conflict resolution on re-sync — reconciles _stock meta across registers and flags oversells for manual review instead of silently overwriting
Installable PWA (manifest.json + service worker with a cache-first strategy) so a tablet or desktop runs the register full-screen, even after a reboot offline
Offline receipt generation from a cached HTML/ESC-POS template, printable to thermal printers via the browser or a local print bridge
HPOS-aware order creation — writes to WooCommerce High-Performance Order Storage custom tables when enabled, or the legacy shop_order post type when not
The core problem it solves: a standard WooCommerce checkout dies the instant connectivity drops, because every "place order" call hits the WooCommerce REST API (/wp-json/wc/v3/orders) live. This plugin flips that. Sales are written to a local IndexedDB queue inside a PWA (installable via a manifest.json + service worker) so cashiers keep ringing up customers with zero network. When the connection returns, a background sync worker replays the queue against the REST API and creates the real WooCommerce orders — into HPOS / custom order tables when enabled, or the legacy shop_order post type otherwise.
The browser caches your product catalog, prices, and tax classes so staff can search and add line items fully offline. On reconnect, an inventory conflict-resolution pass reconciles _stock meta against sales made on other registers, surfacing oversells for review rather than silently corrupting stock. Receipts render and print offline from a cached template.
Because we build to order, the POS is wired into your WooCommerce: your payment methods, your woocommerce_thankyou and order-status hooks, your tax setup, and optionally WPML or multisite. Typical delivery is a few weeks, after which ECOSIRE provides updates and support. You own the code on your server.
Runs one or more counters in an area where the broadband or mobile signal drops several times a day. Needs the register to keep taking sales and printing receipts through every outage, then reconcile cleanly once the line is back.
Already sells online with WooCommerce and wants the physical till to write into the same orders, stock, and customer records — without a separate, siloed POS system that double-counts inventory.
Operates several tills, market stalls, or event booths on the same WooCommerce catalog and needs each terminal to queue independently offline, then merge sales and resolve stock conflicts without overselling.
Buy the license on ecosire.com and download the Offline-First POS for WooCommerce module ZIP from your account dashboard.
Extract the ZIP into your Odoo custom addons folder on the server (or upload via Apps > Install from file on Odoo.sh / runbot).
Activate Developer Mode, open Apps, click Update Apps List, search for Offline-First POS for WooCommerce, and press Install.
Open the new menu, paste your ECOSIRE license key, connect any external credentials (Shopify, Amazon, Stripe, etc.), and save.
Run the built-in connection test, sync your first 10 records, and schedule the recurring cron. Contact support if anything fails.

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.
