From In-Stock Frustration to a Stable Supply Chain: The YLAB Case Study

From In-Stock Frustration to a Stable Supply Chain: The YLAB Case Study

Table of Contents

Introduction

This case study illustrates how Sansansun, through patient communication and strategic guidance, helped our client YLAB transition from the unpredictable nature of re-ordering in-stock items to a stable, reliable custom production model. This shift not only solved their immediate procurement frustrations but also secured their supply chain for a key product, fostering a stronger long-term partnership.

Client Profile: A Brand Reliant on a Best-Selling Style

 YLAB is an SB brand specializing in women’s athletic intimates. They had identified a specific in-stock sports bra from our catalog that became a best-seller for them and sought to reorder it multiple times to meet their customer demand.

The Challenge: The Uncertainty of In-Stock Availability

YLAB grew increasingly frustrated when they found that each time they were ready to place a new order for their key product, it was suddenly discontinued or out of stock. This led to a misunderstanding, where the client suspected we were intentionally limiting availability or were unwilling to continue the partnership. The inability to secure a consistent supply of their best-selling item posed a serious risk to their sales and customer satisfaction.

The Solution: A Shift from Transaction to Partnership

Instead of simply stating the product was unavailable, we took a patient and transparent approach. Across several conversations, we explained the business logic behind in-stock items:

  • They are produced in limited quantities and sold to multiple clients.
  • They are not guaranteed to be available long-term, as factory focus can shift.
  • Most importantly, we proposed a client-focused solution: shift to custom production. This would offer them clear benefits:
    • The ability to lock in the specific fabric, size, and design for their key product.
    • Production schedules tailored to their sales forecast.
    • A complete end to the
    • uncertainty of availability.

The Outcome: A Secure Supply Chain and a Stronger Partnership

YLAB accepted our proposal to shift to a custom production model. They have since completed several custom orders successfully, securing a stable and reliable supply chain for their most important product. This process transformed a point of friction into a stronger, more strategic long-term partnership. It proved that professional patience and a focus on providing solutions—not just explaining problems—is the most direct way to build client trust.

Over the past decade, I’ve worked closely with founders, designers, and product teams across Europe, the US, and the Middle East—helping them turn ideas into scalable collections. My focus is not just on production, but on building repeatable product systems that support long-term brand growth.

 

I believe great activewear is not created by trends or price, but by the alignment of fabric, function, and user experience. Through our MDMD system (Material–Design–Manufacture–Delivery), we help brands reduce development risk, improve consistency, and move faster with confidence.

 

On this blog, I share insights from the factory floor, real client cases, and practical thinking on product development, fabric strategy, and scaling challenges in the activewear industry.
