Mobile POS & Line-Buster turns any phone or tablet into a roaming checkout for Dynamics 365 Business Central, so your staff can scan, sell and take payment anywhere on the shop floor instead of trapping customers in a single queue. It is delivered as a per-tenant AL extension that ECOSIRE builds, installs and supports directly on your Business Central environment — not an off-the-shelf AppSource download.

Under the hood it ships as a Business Central extension package (table and page extensions plus a Business Central-aware web/PWA UI) that writes through the standard BC object model. Sales are created as Sales Orders or Sales Invoices via event subscribers and the BC REST/OData API, so item, customer, dimension, price and inventory logic stay exactly as configured in BC — no shadow ledger. Stock checks read live item availability across your locations, and posted transactions flow straight into the General Ledger.

The handheld UI is built for one-hand use: large tap targets, camera barcode capture, Bluetooth scanner support, and mobile card-reader / tap-to-pay through the payment gateway you already use. Endless-aisle lets associates order items held at another store or in web stock when the shelf is empty. Customers get a mobile receipt by email or SMS and can sign on-screen for delivery or high-value sales.

ECOSIRE scopes your devices, payment provider, locations and permission sets up front, builds the extension to match, installs it on sandbox first, then promotes to production with a tested permission set and job queue configuration. Honest delivery: this is custom work with a real lead time, and ongoing support keeps it aligned with Microsoft's BC release waves.
