THE CUSTOMER
SS Tubes is a leading manufacturer of high-quality brake and fuel lines for classic muscle cars, serving the automotive aftermarket since 1986. With a catalog of over 10,000 parts under its Finelines brand, the company supports a wide range of vehicles and enthusiasts across the U.S.
As the business grew, SS Tubes expanded its operations across ecommerce channels, relying on Shopify for online sales, ShipStation for fulfillment, and QuickBooks for accounting. This multi-system setup enabled growth—but also introduced significant operational complexity that required accurate syncing across inventory, orders, and financial data.
THE PROBLEM
As SS Tubes scaled its product catalog and order volume, its backend systems became increasingly disconnected.
Orders flowing through ShipStation were not automatically syncing with QuickBooks, forcing the team to manually enter and reconcile transactions. Inventory updates from Shopify required exporting files, importing them into QuickBooks, and manually mapping fields—creating a slow and error-prone process.
This led to major operational challenges:
Orders had to be manually entered into QuickBooks
No reliable sync between Shopify, ShipStation, and accounting
Inventory updates required manual imports and mapping
High risk of inaccurate inventory counts and fulfillment delays
Time-consuming workflows that slowed down operations
In a business where inventory accuracy directly impacts customer satisfaction, these inefficiencies created constant friction.

THE SOLUTION
Connex Ecommerce implemented a customized integration across Shopify, ShipStation, and QuickBooks using its flexible Rules Engine.
Instead of requiring SS Tubes to change its existing systems, Connex connected them—creating a seamless flow of data across operations.
Key components of the solution included:
Automated order synchronization from ShipStation into QuickBooks
Real-time inventory updates between Shopify and backend systems
Elimination of manual file imports and field mapping
Centralized, accurate data across ecommerce, fulfillment, and accounting
By aligning these systems, Connex removed the need for manual intervention and ensured consistent, reliable data across the business.
THE RESULTS
The impact was immediate:
Significant time savings by eliminating manual order entry and inventory updates
Reduced errors in inventory counts and order processing
Faster and more reliable fulfillment workflows
Improved visibility across ecommerce, fulfillment, and accounting systems
Scalable infrastructure to support continued catalog and order growth
With Connex in place, SS Tubes transformed disconnected systems into a streamlined, automated workflow—allowing the team to focus on growth instead of manual processes.
