Testimonial by Joe Nixon, COO & CFO of Sweet Wink, a Children’s Apparel & Accessories brand in the US.
About Sweet Wink
Sweet Wink is a modern children's apparel and accessories brand based in New York, founded by the mother-daughter duo Wendi and Samantha. They create joyful, whimsical, and high-quality pieces that make childhood feel magical.
Sweet Wink operates two Shopify stores — one for direct-to-consumer retail and one for wholesale boutiques. Their catalog includes 10,000+ SKUs and more than 5,000 bundles, many of which overlap across both stores.
Wholesale orders are large and complex, often containing 100 to 400+ line items with bundles made up of multiple components.
The team also runs a print-on-demand workflow, stocking blank apparel and applying custom artwork in-house. This means inventory availability depends on component-level accuracy and production feasibility.
Managing this level of complexity across two stores with overlapping products required a system built for high-volume, bundle-heavy operations.
The Challenge Sweet Wink Faced
As Sweet Wink scaled, inventory management became harder to control across two Shopify stores:
Broken Bundle Calculations: Every bundle sale required multiple component deductions, and the math was often wrong.
Wasted Warehouse Time: Warehouse staff spent 10 to 20% of their time manually counting inventory to verify system accuracy.
Inventory Misalignment: Retail and wholesale inventory didn't sync reliably, causing stock mismatches and preventing confident scaling.
Manual Sales Updates: Sales team had to manually track availability on wholesale side, creating delays and limiting growth confidence.
How Sumtracker Helped Sweet Wink

Why did Sweet Wink struggle with inventory before Sumtracker?

How does Sumtracker handle Sweet Wink's bundle complexity?
Sweet Wink's bundles contain multiple components, and each must deduct correctly in real time. Sumtracker deducts at the component level for every bundle, even in large wholesale orders with hundreds of line items, partial fulfillments, or edited orders. This reduced bundle errors by 99.5 percent.
How did accurate inventory change Sweet Wink's business?
Before Sumtracker, Sweet Wink was hesitant to take on new wholesale opportunities because they couldn't trust their inventory numbers. After implementing Sumtracker, they had complete confidence in their stock levels. This let them take on every opportunity with confidence, buy more inventory, and significantly increase sales.
How much time did Sweet Wink save on inventory management?
Warehouse staff previously spent 10 to 20% of their time manually counting and verifying inventory. With Sumtracker's accurate tracking, that manual work stopped.

How did Sumtracker help Sweet Wink's wholesale business?
