Bu Ürün Hakkında
Sell through the outage, reconcile when you're back
Most Business Central POS integrations assume a live connection. When the link drops, the register either freezes or — worse — staff fall back to paper and you reconcile by hand later. The Offline-First POS Sync Engine removes that failure mode. It is a build-to-order per-tenant AL extension that ECOSIRE designs, builds, installs and supports directly on your Business Central environment (online or on-prem) — not an instant AppSource download.
How it works
Each register holds a local transaction cache plus a point-in-time snapshot of item prices, active promotions and on-hand inventory pulled from BC. Checkout continues fully offline against that snapshot. The moment connectivity returns, a queued sync worker replays every offline transaction into Business Central through the BC REST/OData v4 API and posts the resulting sales documents.
Posting is idempotent: each offline transaction carries a client-generated unique key, and an AL event subscriber on the sales posting routine rejects any replay that has already landed — so a flaky connection that retries three times still produces exactly one sales entry, never duplicates.
Built into Business Central properly
We deliver real BC objects, not a bolt-on: table extensions for the offline queue and sync ledger, page extensions surfacing a per-device sync-status dashboard, a Job Queue entry that drains the replay queue on a schedule, dedicated permission sets, and event subscribers for conflict-free reconciliation. Optional Dataverse / Power Platform wiring lets you alert on stuck transactions from Power Automate.
ECOSIRE handles the AL development, the per-tenant install, UAT against your live catalog, and ongoing support and BC version-update compatibility. You get the source-aligned extension running in your own tenant — honestly scoped, honestly delivered.

Bu kimin için
Multi-store retail operations manager
Runs several branches on Business Central where at least one site has unreliable broadband. Needs every till to keep selling during outages and to trust that the day's sales reconcile into BC exactly once, with a clear dashboard showing which registers are behind.
Pop-up and market vendor
Sells at fairs, markets and temporary locations where Wi-Fi and mobile signal are intermittent or absent for hours. Wants checkout that never stops, working off a local price and promo snapshot, then auto-syncs to BC the instant a connection appears.
Franchise IT / BC administrator
Owns the Business Central tenant across franchised stores and is accountable for clean financials. Needs idempotent posting, per-device permission control, an auditable sync ledger and stuck-transaction alerts rather than late-night manual reconciliation.

Offline-First POS Sync Engine hakkında Sıkça Sorulan Sorular
How long does delivery take, and what is the process?
This is a build-to-order extension, not an instant download. After a short scoping call we confirm your register topology, catalog size and BC version, then build and install the per-tenant AL extension. Typical delivery is one working week depending on how many register configurations and conflict rules you need. The flow is: scope and fixed quote, build, install into a sandbox, UAT against your live price/promo/inventory data, then promotion to production with sign-off.
How is ongoing support and Business Central compatibility handled?
Because we install the extension in your own tenant, ECOSIRE provides post-launch support and keeps it compatible across Business Central updates. Microsoft ships major BC releases twice a year; we test the extension against each relevant update and ship any required AL fixes under your support agreement. Support covers reprocessing stuck transactions, tuning the Job Queue cadence and offline caps, and adjusting conflict rules as your catalog evolves. Support terms and response times are agreed in writing before go-live.
Will offline replays ever create duplicate sales in Business Central?
No. Every offline transaction carries a client-generated unique key. An AL event subscriber on the sales posting routine checks that key against the sync ledger before posting, so a transaction that the connection retries multiple times still produces exactly one BC sales entry. Failed or partial replays are flagged in the dashboard for review, never silently re-posted.
What happens to inventory and pricing if they changed in BC while a register was offline?
Each register sells against a snapshot captured when it was last online. At replay time the engine detects drift — for example a price change or an item that went out of stock centrally — and flags those transactions for store-manager review rather than overwriting silently. You decide the conflict policy during scoping (accept-as-sold, adjust, or hold), and we encode it into the reconciliation event subscribers.
Does this run on Business Central online (SaaS) or on-premises?
Both. The extension is delivered as a per-tenant AL extension that installs into a BC SaaS environment or an on-premises deployment. It integrates through the standard BC REST/OData v4 API and standard BC objects (table/page extensions, event subscribers, Job Queue, permission sets), so it lives inside your environment under your governance rather than depending on external middleware.
