Magento 2 Offline POS Mode

Hauptfunktionen

Continue completing sales with zero internet connection — the register never blocks on a network round-trip

Local catalog, price, tax-rule, and recent-customer cache via Service Worker + IndexedDB, refreshed automatically while online

Durable offline order queue with client-generated idempotency keys so reconnect replays can never double-post a sale

Automatic queued-order sync on reconnect, replayed through guarded Magento service contracts (REST/GraphQL), with a cron safety net to catch missed flushes

Conflict-safe stock reconciliation that detects oversells and flags them for admin review instead of silently corrupting quantities

Offline receipt printing from a cached template — full receipt every time, online or offline

MSI / multi-source-inventory aware reservations on supported Magento versions, scoped to the register's assigned source

Admin grid showing every queued, synced, and failed offline transaction with replay and audit detail

Dedicated admin ACL resource so offline-POS configuration and the sync queue are role-restricted

Configurable cache-staleness and price-lock window so offline prices stay within merchant-approved bounds

System configuration for queue retention, retry/back-off policy, and reconnect behaviour — no code edits to tune

Clean module under app/code/Ecosire/OfflinePos with di.xml, plugins/observers, service contracts, and full upgrade scripts you own

Über dieses Produkt

Most Magento POS workflows die the instant the connection drops — the cart can't reach the GraphQL/REST endpoint, inventory won't reserve, and the register stops taking money. Magento 2 Offline POS Mode removes that single point of failure. It is a custom-built extension that ECOSIRE engineers, installs, and supports directly on your Magento Open Source or Adobe Commerce instance — not an instant Marketplace download.

The module ships as a versioned package under app/code/Ecosire/OfflinePos, wiring in through di.xml, an admin ACL resource, system configuration, and dedicated service contracts so behaviour is testable and upgrade-safe. When the browser detects loss of connectivity (Service Worker + IndexedDB cache), the POS keeps selling against a locally cached snapshot of your catalog, prices, tax rules, and recent customers. Each completed sale — line items, tendered payment, and the resulting stock movement — is written to a durable local queue.

The moment connectivity returns, a reconnect handler (backed by a Magento cron safety net) replays the queue through guarded service-contract calls. Orders are created idempotently using client-generated keys so a flaky network can never double-post a sale. Stock is reconciled through Magento's inventory APIs (MSI-aware on supported versions) with a conflict-safe strategy that flags oversells for review instead of silently corrupting quantities. Offline receipts print from the cached template the whole time, so the customer experience never changes.

Because it is build-to-order, we adapt the queue, payment capture, and reconciliation rules to your gateway, tax setup, and store/source structure — then hand over clean, documented code you fully own.

Admin queue grid, ACL resources, and system-configuration panel for retention, retry, and price-lock policy

Integration of offline receipt printing with your current receipt template and printer setup

Technical documentation, an admin runbook for handling flagged conflicts, and source code you fully own

Post-deployment support window, bug fixes, and compatibility checks against your Magento version upgrades

Für wen das ist

High-traffic store owner

Runs busy physical or hybrid stores where even minutes of checkout downtime means lost sales and long queues. Needs the till to keep taking money no matter what the ISP is doing.

Retailer in a low-connectivity region

Operates in areas with frequent power or internet outages. Cannot rely on always-on connectivity to Magento and needs a register that degrades gracefully and self-heals on reconnect.

Magento operations / IT lead

Owns the Magento Open Source or Adobe Commerce stack and wants offline resilience implemented as clean, upgrade-safe code under app/code — service contracts, ACL, cron — not a brittle theme hack, with documentation and a support path.

Häufig gestellte Fragen zu Magento 2 Offline POS Mode

How long does it take to build and deliver this extension?

Because every Magento install differs, this is build-to-order. After a short scoping call to confirm your version (Open Source vs Adobe Commerce), POS front end, payment gateway, and inventory model, typical delivery is about 2 to 4 weeks: build on a staging copy, joint testing including simulated outages, then a supervised production install. Complex MSI or multi-store setups may extend this — we give you a firm timeline before you pay, not an instant download.

What ongoing support and updates are included?

Delivery includes a post-deployment support window for bug fixes and questions, plus the documented runbook for handling flagged stock conflicts. Because you receive and own the source code under app/code, you are never locked in. We also offer optional ongoing maintenance to re-verify the module against future Magento and Adobe Commerce upgrades, since core inventory and API behaviour can change between versions.

Won't offline orders create double-posted sales or oversells when the connection comes back?

No. Each offline sale gets a client-generated idempotency key, so replaying the queue on reconnect — whether triggered by the reconnect handler or the cron safety net — creates each order exactly once, even on a flaky link. Stock is reconciled through Magento's inventory service contracts; if two registers sold the last unit while offline, the system flags the oversell in the admin queue grid for review rather than silently corrupting quantities.

Does this work with Adobe Commerce and Magento Open Source, and with MSI?

Yes to both editions. We build against your specific version and target Magento's service contracts and inventory APIs rather than patching core, so it stays upgrade-safe. On versions with Multi-Source Inventory, the offline layer is MSI-aware and scopes reservations to the source assigned to that register. We confirm exact version and MSI support during scoping.

How does the POS know prices and products while offline?

While online, a Service Worker keeps an IndexedDB snapshot of your catalog, prices, tax rules, and recent customers fresh in the background. If the connection drops, the register sells against that cached snapshot. You control a cache-staleness and price-lock window in system configuration so offline prices always stay within merchant-approved bounds, and the cache refreshes automatically the moment connectivity returns.

Is this a Marketplace extension I can download and install myself?

No — and we are deliberate about that. Offline resilience touches your payment capture, tax rules, and inventory reconciliation, which are too install-specific for a generic one-click package. ECOSIRE builds, installs, and supports it directly on your Magento instance, then hands over clean, documented code that you own. There is no public Marketplace download link for this module.
