Sellino POS – Point of Sale & Inventory System

Sellino POS – Point of Sale & Inventory System

Sellino POS is a complete point of sale, inventory and accounting system for real shops — supershop, grocery, pharmacy, fashion, hardware, restaurant and any counter-based retail business running one outlet or twenty.

From one Laravel backend you get a fast counter POS, a full back office and a Flutter POS App for Android and iOS. Everything ships together in the main download package and talks to a single backend and database over a REST API.

Every checkout moves stock, posts to double-entry accounts, balances the cash drawer and credits loyalty points — automatically, in the branch it was rung up in. The platform supports multi-language usability with RTL and LTR layouts across web and mobile.

What You Get

• Laravel Web Backend — POS terminal plus the full admin back office (inventory, accounting, HR, reports).
• POS App (Flutter) — counter app for Android and iOS: sell, take cash, check stock, read reports. Both platforms are included — one Flutter codebase with the Android and iOS projects in the package; nothing is sold separately or excluded.
• Multi-branch built in — branches group warehouses, counters and staff; every order, till and report follows the branch it belongs to.
• Full source code for the backend and the app, the database, and complete documentation — all inside the main Main_Files.zip.

Who It Is For

Single shops and multi-branch chains that sell at a counter and want the stock ledger, cash book and profit & loss to take care of themselves. There is no online storefront and no vendor marketplace in this item — it is a shop system, not a webshop, so nothing in the panel is noise you have to work around.

Important Note About Third-Party Service Costs

Any costs related to hosting, domains, server infrastructure, SMS gateway providers, WhatsApp API providers, email services, push-notification (Firebase) services, Apple/Google developer accounts for publishing the app, receipt printers, barcode scanners or any other third-party service or hardware are not included in the item price. Buyers must purchase and configure these separately based on their own requirements. You also generate your own application key and configure your own credentials during setup.

POS Terminal (Web & App)

• Fast counter sales — search or scan, add to cart, take payment in seconds
• Multi-payment on one bill: cash, bank, mobile money (MFS) or a mix, with change calculation

Multi-Branch

• A branch groups its own warehouses, counters and staff — run one shop or a whole chain from one install
• Staff are assigned to branches, with a per-user visibility rule: all branches, assigned only, their own, or only what they created
• The cashier picks the branch at the till (web and app); stock, tills and reports all follow it

• Stock transfers between branches with request, approve and receive steps

Inventory & Purchasing

• Bank and MFS accounts, deposits, fund transfers, owner withdrawals and investments
• Bank statement import and reconciliation
