Build a Point of Sale (POS) System with AI - in Hours

ProjectCode generates a complete, production-ready Point of Sale (POS) System from a single natural language prompt. In hours instead of months, you get a React frontend, NestJS REST API, PostgreSQL database, and authentication - fully integrated, live-previewed, and deployed to a URL you own.

Estimated build time: 2–4 hours

01 · The Challenge

Why building a POS from scratch is hard

Building a Point of Sale (POS) System from scratch requires months of development time and significant engineering resources. Teams struggle to coordinate frontend, backend, database, and authentication while managing pos-specific business logic, integrations, and role-based access rules.

02 · What's Included

Everything your POS needs

ProjectCode generates a production-ready POS with all the modules your team needs from day one.

Fast touch-optimized sales interface for cashiers
Barcode scanning and product search
Multiple payment types: cash, card, split payment
Real-time inventory deduction on sale
Receipt printing and email receipt support
Shift management with opening/closing float reconciliation
Product returns and exchange workflows
Sales reports: hourly, daily, by product and cashier

03 · Architecture

How it's built

The generated POS follows production-grade architecture patterns.

React 18 + TypeScript frontend with role-based dashboards tailored for pos workflows

NestJS REST API with dedicated pos modules, DTOs, validators, and service layer

PostgreSQL relational schema with normalized tables for all pos entities

JWT + Google OAuth authentication with granular permission gates per role

Real-time Socket.IO events for live pos status updates and notifications

Managed hosting with one-click deploy, custom domain, and auto-SSL

04 — Database

PostgreSQL schema designed for POS

ProjectCode generates a normalized, indexed PostgreSQL schema with the right tables and relationships for your use case. You own the schema and can evolve it freely.

  • transactions (id, cashier_id, register_id, items jsonb, subtotal, discount, tax, total, payment_method, payment_ref, receipt_number, created_at)
  • registers (id, name, location_id, current_float, status, opened_at, opened_by, closed_at)
  • products (id, barcode, name, price, category_id, inventory, tax_category, is_active, workspace_id)
  • shifts (id, register_id, cashier_id, opening_float, closing_float, cash_sales, card_sales, variance, started_at, ended_at)
