Half Price Drapes is a United States–based home furnishings brand specializing in custom curtains and window treatments. As an established ecommerce retailer, they needed to expand their customization capabilities with a system built to manage complex sizes, attributes, and pricing variations at scale.
Half Price Drapes needed a system that could support detailed configuration without manual effort. Their previous Shopify site was built on outdated code, older logic, and an aging interface, which limited the depth of personalization required for custom curtains and Roman shades. Customers also lacked dynamic cost calculation, reducing clarity during the buying process and increasing operational strain for internal teams.
Managing multiple attributes and size combinations required accurate calculations that Shopify could not generate automatically. The team needed a reliable way to generate precise prices without manual oversight.
Shopify’s native capabilities could not support the configuration rules needed for advanced custom products. This limited their ability to expand configurable offerings effectively.
Pricing updates, inventory checks, and attribute rule management depended on manual workflows. This created inconsistencies and slowed order fulfillment.
Pricing on the old site used outdated manual methods, creating extra effort, slow updates, and unclear details for customers. Manual and legacy approach…
Fabric-level inventory and custom product availability were not connected, resulting in mismatches between options selected and actual stock.
We demonstrated strong experience building detailed pricing logic tailored to unique product rules.
Our background in complex storefront logic gave the client confidence we could manage their attribute-driven requirements.
They needed a partner capable of creating a stable, scalable Shopify ecosystem aligned with their customization roadmap.
We ensured the system could support Shopify Magic and MCP–ready enhancements that aligned with their long-term plans.
We created a JavaScript-driven pricing engine capable of calculating costs instantly as customers selected attributes such as size, lining, fabric type, and customization options. This system operated entirely within Shopify’s constraints while maintaining precision. It allowed customers to understand cost in real time, removed guesswork, and eliminated manual calculations for internal teams. The pricing logic now scales across multiple product categories without requiring ongoing developer intervention.
We developed a dedicated Shopify app to manage the full customization workflow. It centralized configuration rules, pricing tables, and product relationships. The app allowed staff to update attribute rules, approve combinations, and adjust configuration logic from a clean interface. This replaced the need for scattered spreadsheets or manual overrides and provided a stable foundation for frequent product updates.
Using the Cart Transform API, we ensured that every unique configuration mapped correctly to the correct variant and pricing rules. The system validated selections, applied accurate pricing, and ensured each cart entry reflected the exact configuration chosen. This created a reliable cart experience for custom products while maintaining Shopify compatibility.
A webhook-based syncing system was introduced to connect fabric-level SKUs with all dependent custom products. With every change in fabric inventory, associated customizable items are updated instantly to reflect accurate stock levels. This removed mismatches between available fabrics and selectable configurations, ensuring the merchandising team could rely on real-time availability and preventing customers from choosing options that weren’t actually in stock.
A streamlined admin interface was developed to help staff manage size rules, attribute combinations, fabric mapping, and configuration logic. The dashboard was intentionally built for non-technical teams, allowing quick updates without developer involvement. As a result, operational tasks became simpler, rule changes were completed faster, and the internal team maintained full control over the customization logic with minimal training.
We designed a modern vertical-slider interface to improve product discovery and create a clearer visual experience. The updated layout presents categories, featured items, and promotions in a smooth, scroll-based flow that aligns with current design standards. This reduced clutter and helped customers browse more intuitively across devices. The slider approach also gave the merchandising team greater flexibility in showcasing curated content.
We implemented a complete workflow connecting the storefront, pricing engine, inventory logic, and admin controls. Customers could configure products, see accurate instant pricing, add custom items to cart, and complete purchases with confidence. Internally, the team gained a clear, automated process for maintaining and updating their custom product catalog.
