Can the POS connect to a barcode scanner?

Yes. The product search supports USB HID barcode scanner input out of the box. Simply plug in the scanner and it works as a keyboard input device.

How does shift reconciliation work?

At shift end, cashiers enter the physical cash counted in the drawer. The system compares it against the calculated cash float (opening float plus cash sales) and reports the variance.

Can it print receipts?

Yes. The generated app supports both thermal printer receipt printing (via ESC/POS commands over network or USB) and email receipts. The receipt template is fully configurable.

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

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.

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

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

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)

FAQ

Common questions about building a POS

The generated POS uses a local-first approach with service workers and IndexedDB caching. It continues to process sales offline and syncs transactions when connectivity resumes.
