The Vision & Challenge
A leading B2B print-on-demand provider supplied custom apparel to a growing network of e-commerce businesses. While their product quality was high, their growth was limited by the manual processes required to onboard new merchants and handle their orders.
Every new partner required direct contact with a sales representative. Product catalogs had to be managed manually, and each order was processed by hand. This operational friction created a ceiling on how many merchants they could effectively serve, capping their potential revenue and market reach.
Robust Devs was engaged to design and build a public Shopify application. The goal was to replace the high-touch, manual sales process with a scalable, self-service channel that could directly integrate with a merchant's storefront, automating everything from product selection to final fulfillment.
Project challenges
- Maintaining real-time data integrity for product details, pricing, and stock levels across the provider’s central catalog and thousands of independent Shopify stores.
- Developing a client-side product customizer that was both intuitive for non-technical users and precise enough to handle various logo formats and text placements for print production.
- Architecting a secure and automated B2B transaction workflow to manage order ingestion, wholesale invoicing, payment processing, and shipment notifications between two distinct parties.
Solutions
- We built a robust backend using Laravel to communicate with the Shopify API. This service managed two-way synchronization, using webhooks and scheduled jobs to ensure product and inventory data remained consistent.
- A React-based customization tool was developed, allowing merchants to upload logos and add text directly onto product mockups. The interface provided real-time visual feedback while validating file types and dimensions for production.
- We designed a complete order management system that automatically pulls new orders from Shopify, generates wholesale invoices for the merchants, and integrates a payment gateway. An administrative backend provides staff with the tools to update fulfillment status and tracking information.

Interactive Product Customizer
Merchants can design their products directly within the application. They can upload vector or raster logos, add custom text with full font controls, and precisely position these elements on high-resolution product mockups. This gives them creative control and ensures the final output meets production standards without back-and-forth communication.
Automated Inventory and Order Sync
The application creates a direct link between the provider’s catalog and the merchant's store. All product information, including SKUs, descriptions, and stock levels, is synchronized automatically. When a customer places an order on the merchant's site, it is instantly ingested into the provider's fulfillment queue, removing all manual data entry.
