The Challenge: Using Nimble NetSuite Capabilities to Respond to Tariffs

For more than five years, ExtendApps partnered with Jolyn to build and support their mission-critical integrations between Shopify, NetSuite, and their 3PL network—supporting the brand through a period of extraordinary hypergrowth.

But when rapidly escalating North American and China-focused tariffs threatened to upend Jolyn’s supply chain, inventory routing, and fulfillment workflows, the stakes changed overnight. The existing flow of orders, sourcing assignments, vendor processes, and logistics assumptions no longer worked.

Jolyn needed to pivot—fast.

With only days' notice and a three-week deadline to execute, the company turned to the partner they trusted most: ExtendApps.

The Solution: Rapid Reconfiguration Across NetSuite, Shopify & 3PL Systems

ExtendApps immediately mobilized to understand the tariff impacts and how they cascaded across Jolyn’s order management, sourcing, and fulfillment processes. Our focus was simple: protect the customer experience while rebuilding the operational workflow beneath it.

A Fast, Coordinated Response

Our team worked side-by-side with Jolyn’s leadership and operations teams to:

• Analyze tariff-driven pricing, sourcing, and routing impacts

• Define required changes to NetSuite configurations and automations

• Update Shopify and 3PL integrations to support new flows

• Plan testing and cutover steps that would avoid customer disruption

Rebuilding the Supply Chain Through NetSuite

ExtendApps implemented targeted but high-impact adjustments across the ecosystem:

• Updated NetSuite item, vendor, and sourcing rules to support new tariff logic

• Reconfigured automations to re-route fulfillment and inventory movements

Despite the scale of the change, Jolyn’s customers never felt the turbulence happening behind the scenes.
