Operating across multiple brands, with established pricing arrangements and a growing catalog, it needed ecommerce that works with [Sage 100](/integration/sage-100) rather than becoming another disconnected source of truth. Uncap implemented Shopify B2B with company accounts and catalogs, mapped the company's four ERP pricing levels to catalog-based pricing, and, working with an integration partner, connected Shopify and [Sage](/integration/sage) 100 across products, inventory, customers, pricing, orders, and fulfillment. ## The Who Great Lakes Wholesale Group is a wholesale distributor operating across multiple brands, serving customers with established pricing arrangements and a growing product catalog. Its Sage 100 ERP already managed the essential business information: customers, products, inventory, and pricing. ## The Problem The company needed to modernize digital commerce without disrupting the ERP-driven processes behind the business, starting from a website built in the 1990s. Any new ecommerce experience had to accommodate complex customer relationships, account-specific pricing, and catalog growth, and it had to work with the existing systems rather than introduce another disconnected source of truth. ## The Solution Uncap implemented Shopify's native B2B architecture, with company accounts and catalogs carrying the wholesale relationships and the four established Sage 100 pricing levels mapped to catalog-based pricing. Working with an integration partner, Uncap connected Shopify and Sage 100 to synchronize product records, inventory, customer and company data, pricing, orders, and fulfillment updates, and brought the company's brands together under one commerce infrastructure with modern navigation, organized collections, and customer-specific catalog access. Launch preparation included customer-data cleanup, synchronization-rule validation, and production-readiness coordination across business, technical, and implementation teams. ## The Results Great Lakes Wholesale launched its new Shopify ecommerce operation in 2026: a modern B2B foundation with account-based wholesale pricing aligned to Sage 100, synchronized operational data behind every transaction, improved product discovery and customer account experiences, and a scalable architecture for continued wholesale development. Early rollout brought orders, email registrations, and engagement with the new website.
