Sellino – Multi-vendor eCommerce and POS PHP Script with Customer and Seller Apps

Sellino is a complete multi-vendor eCommerce, supershop, POS and accounting system for real-world retail businesses — grocery, supershop, pharmacy, fashion and multi-vendor marketplaces.

From one Laravel backend you get a customer-facing online store, a fast counter POS, an admin panel, a seller/vendor panel, and two native Flutter mobile apps — a Customer App and a Seller App. Everything ships together in the main download package and connects to a single backend and database over a REST API.

The platform supports multi-language usability with RTL and LTR layouts for a better experience across web and mobile.

What You Get

Laravel Web Backend — admin panel, seller/vendor panel and customer storefront, with built-in POS.
Customer App (Flutter) — native shopping app for Android and iOS.
Seller App (Flutter) — native merchant app for Android and iOS.
Full source code for the backend and both apps, the database, and complete documentation — all inside the main Main_Files.zip.

AI Features (Optional, Disabled by Default)

Sellino includes two optional AI-assisted features. Both ship switched off, both are configured from the admin panel, and the whole platform works normally with them disabled.

AI auto-reply (Message Center) — when no auto-reply rule matches an incoming customer message, an AI assistant can draft the reply. It runs on your own API account with the Anthropic (Claude) API or any OpenAI-compatible provider (OpenAI, Gemini, Groq, DeepSeek and similar). You enter your own base URL, model and API key, set a monthly budget cap, and the assistant mutes itself in a conversation as soon as a human staff member replies.
Search by image — customers can search the catalogue with a photo. The default driver is a free on-server perceptual-hash matcher with no external calls; you may optionally point it at an external vision API (your own URL, model and key) for stronger matching.

No AI keys or credits are included with this item. These features call third-party AI services under your own account and are billed by those providers on a pay-as-you-go basis. Message content sent to an AI provider is processed under that provider’s own terms and privacy policy. Generated replies are machine-produced and should be reviewed for accuracy — you stay in control of what your customers receive.

Important Note About Third-Party Service Costs

Any costs related to hosting, domains, server infrastructure, payment gateways (Stripe, PayPal, SSLCommerz, bKash, Nagad, EPS), SMS gateway providers, WhatsApp API providers, email services, push-notification (Firebase) services, AI providers (Anthropic / Claude API or any OpenAI-compatible provider) and any external vision API used by the optional AI features, Apple/Google developer accounts for publishing the apps, or any other third-party service are not included in the item price. These are independent third-party services: buyers must open their own accounts, accept those providers’ own terms, and pay their subscription and per-transaction fees directly to them. In particular, Stripe and PayPal are third-party services: you register and verify your own Stripe / PayPal Business account and pay their transaction fees yourself. You also generate your own application key and configure your own credentials during setup.
