POS

Modern point-of-sale systems built for speed, reliability, and real business insight.

Custom POS solutions that streamline retail and restaurant operations with real-time inventory, sales analytics, and offline resilience.

What We Deliver

We engineer scalable, high-performance software modules tailored to match your specific technical and commercial objectives.

Transaction Uptime
99.97%
01

Off-the-shelf POS systems make you pay for features you don't need and force your operations into workflows that don't fit your business. CodeAdda builds bespoke point-of-sale solutions — web-based, tablet-native, or desktop — that are designed around how your team actually works, not the other way around.

02

Our POS systems are engineered for reliability first. Offline mode means sales continue processing even when the internet goes down, with automatic queue-based sync once connectivity returns. Every transaction is logged with a full audit trail, and your real-time dashboard shows sales velocity, top products, staff performance, and low-stock alerts the moment they matter.

03

We integrate with the payment processors and receipt printers you already use (Stripe Terminal, Square Hardware, Star Micronics, Epson), so there's no forced hardware migration. Inventory, sales data, and customer records sync bidirectionally with your e-commerce store, giving you a single source of truth across all your sales channels.

Key Features

Custom POS Interface

Tablet-first or desktop POS UI designed for your specific product catalog, workflow, and staff skill level — with fast-key shortcuts and barcode scanner support.

Offline-First Architecture

SQLite-backed local processing means transactions never stop. Failed network requests are queued and synced automatically when connectivity restores.

Real-Time Inventory

Stock levels update with every sale and purchase order. Low-stock alerts, supplier reorder suggestions, and expiry tracking included.

Payment Processor Integration

Stripe Terminal, Square, Adyen, or SumUp hardware — we integrate your preferred payment stack with full PCI DSS compliance.

Staff Management & Permissions

Role-based access (cashier, manager, owner), shift-based sales attribution, and manager override workflows built in.

Reporting & Analytics Dashboard

Daily, weekly, and monthly sales reports with product performance breakdowns, peak hour heatmaps, and CSV/Excel export.

Methodology

How We Work

A structured, milestone-driven development process centered on velocity and transparency.

01

Operations Mapping

We shadow your current checkout and inventory workflow, document every edge case, and map the POS feature set to your exact operational needs.

02

Hardware & Integration Scoping

We select and test compatible receipt printers, barcode scanners, cash drawers, and card readers before writing a line of application code.

03

Phased Build & Staff Testing

We build in phases — core transaction flow first, then inventory, then reporting. Staff test each phase in a sandboxed environment.

04

Go-Live & Training

On-site or remote go-live support, staff training sessions, and a 60-day hypercare window for bug fixes and usability tweaks.

Tools & Tech Stack

We design and maintain our stacks using leading-edge development environments.

Questions

Frequently Asked

Can the POS system work on our existing hardware?

We support modern tablets (iPad, Android), touchscreen Windows desktops, and standard POS peripherals (Star, Epson printers; Honeywell, Zebra scanners). We'll confirm compatibility in the scoping phase before any commitment.

What happens if the internet goes down mid-shift?

Offline mode activates automatically. Transactions process locally and sync to the server the moment connectivity returns. Your staff won't notice the interruption.

Can it integrate with our e-commerce store?

Yes — we build bidirectional sync between the POS inventory and your Shopify, WooCommerce, or custom e-commerce backend. Stock updates in real time across all channels.

Is card processing PCI DSS compliant?

All integrations are built on certified payment processors (Stripe, Adyen) with point-to-point encryption (P2PE). We never store raw card data.

Can we add more locations later?

Multi-location is a first-class architectural concern. Each location has its own inventory and sales context, with a consolidated owner dashboard showing the full business picture.
