The Challenge

Ethos Merch specializes in made-to-order custom apparel and offers a unique managed web-store service for wholesale clients like yoga studios, fitness communities, and wellness brands. Their business model involves printing products on demand—meaning every order pulls from a shared pool of raw materials, such as blank shirts, hoodies, or tanks.

Before Synkro, managing this inventory model across multiple Shopify stores was complex and time-consuming:
‍

• Every printed product variation needed to reflect the real-time stock of its underlying raw material
• When one product sold, inventory had to be manually adjusted across dozens (sometimes hundreds) of other product listings tied to the same base item
• Wholesale client storefronts required consistent and accurate syncing of product data from the main supply store
  ‍

Manual inventory tracking was not only inefficient—it also risked overselling, miscommunication, and fulfillment delays.
‍

The Solution

With Synkro, Ethos Merch was able to fully automate their inventory and storefront management. Key capabilities include:
‍

• Master Inventory System to link printed SKUs to their base raw-material product, ensuring every variant stays perfectly in sync
• Real-time inventory updates across all printed versions when a raw material is used
• Product and inventory sync between the primary supply store and each client’s branded storefront
• One-click onboarding of new wholesale clients by cloning and tagging products for cross-store availability
  ‍

This system ensures accurate stock levels, no matter which version of a product is sold or where the order comes from.
‍

How the Master Inventory System Works
‍

Ethos Merch uses Synkro’s Master Inventory System to define a base product (e.g., “Small Grey Shirt”) as the source of truth. Any printed or branded version of that shirt across multiple storefronts is linked to this master inventory.

When one version sells, Synkro automatically deducts inventory from the raw material and updates all linked printed versions—instantly.
‍

This eliminates duplicate data entry, prevents overselling, and supports a highly scalable print-on-demand model across dozens of client stores.

“Synkro has been a game-changer for managing inventory across my multiple Shopify stores. Whether I update a product in one Shopify store or receive new stock, the changes instantly reflect across all connected stores. This has saved me countless hours, reduced errors, and helped me maintain a consistent customer experience no matter which store the order comes through.”

By leaning on Synkro’s robust syncing infrastructure, Ethos Merch can focus on growing its network of wholesale partners—confident that inventory and product data will always be accurate and in sync.
