Custom POS Solutions for Shopify: Maximize Retail Performance

For apparel retailers, every oversell, delayed inventory update, or slow checkout eats directly into profits. Our client — a US-based premium apparel retailer — was struggling with high third-party platform fees, inventory mismatches, and manual accounting chaos. Sales were steady, but profits were shrinking. Custom POS solutions were the need of the hour.

To address these challenges, our team leveraged advanced POS integration services to build a custom solution that allows integration with more tools, optimizes checkout, and improves real-time inventory management. The result? 25% sales growth, 15–20% higher profit margins, and seamless operations across online and in-store channels

Enhancing Shopify POS with Custom Solutions: Case Study

The client, a US-based personalized apparel retailer, sold premium products from top-tier suppliers. However, they relied on a third-party platform (Inksoft) to manage online sales. The platform was not performing effectively for them. High platform fees and per-item commissions were significantly reducing profits.

Additionally, their physical store relied on manual recordkeeping. This led to inventory mismatches, delayed accounting, and operational chaos. Managing stock, updating prices, and handling orders for online and offline channels was a daily challenge

To enhance these processes, our team at The Brihaspati Infotech built a custom POS solution on Shopify — fully integrated with QuickBooks, supplier APIs, and advanced product customization features. 

The result? Smoother workflows, greater accuracy, and lower costs. Finally, profit margins are back under their control.

Here’s an overview of how our custom solution streamlined their processes and boosted efficiency:
