Problem

Independent retailers were running their business on disconnected tools: a cash register or spreadsheet for in-store sales, a marketplace storefront that charged commission on every order, and manual stock counts to keep the two in sync. Inventory drifted apart daily — products sold out online while sitting on shelves, and in-store sales never reached the online catalog. Every marketplace sale also gave away margin in commission fees.

Solution

CommerceSystem replaces that patchwork with one integrated retail platform: a central Laravel API that owns products, stock, and transactions, an Angular POS for in-store cashier operations, and a Next.js storefront the business owns outright — no marketplace, no commission. Every sale, whether at the counter or online, updates the same inventory in real time.

Features

Architecture

The system follows an API-first design. A Laravel REST API is the single source of truth for products, inventory, and transactions. Two independent frontends consume it: an Angular single-page application optimized for POS speed at the counter, and a Next.js storefront optimized for SEO and customer browsing. Because all writes flow through one backend, transactional consistency and inventory integrity are enforced in a single place, and additional channels can be added without touching the core.
