The Challenge

Scaling a 500+ SKU catalog efficiently

Bombay Shirt Company had a wide catalog and a strong offline presence, but needed a smarter way to grow online sales without wasting ad spend.

About the Brand

Bombay Shirt Company is India’s first online custom shirt brand — offering 500+ products across a rich catalog of styles, fabrics, and occasions.

With a strong offline presence but low online conversions, the brand needed to shift to a product-led performance approach — identifying profitable SKUs, improving budget allocation across Meta and Google, and using product analytics to scale the right products.

Limited Product & Category-Level Insights

With a wide range of products, the team had no visibility into which SKUs and categories were actually profitable on a per-product basis.

Low Discoverability for 200+ SKUs

More than 200 SKUs were undiscoverable or zombie products because ad spend was skewed unevenly across the catalog.

Inefficient Budget Allocation

The brand was heavily dependent on Meta. To scale order volume, it needed to diversify channels and allocate spend more efficiently across products.

The Approach

Product Performance Management

BigAtom’s Product Performance Quadrants revealed the true state of Bombay Shirt Company’s catalog — and defined a clear strategy for every product segment.

Low Spend · High ROAS

High Potential Products

400+ SKUs had strong potential but insufficient budget — profitable products waiting to be unlocked with dedicated ad spend.

High Spend · High ROAS

Hero Products

Only 56 SKUs were truly profitable for the brand. These were the priority products to protect and scale further.

Low Spend · Low ROAS

Low Discoverability

200+ products needed better visibility and testing before a confident budget decision could be made.

High Spend · Low ROAS

Non-Performers

63% of ad spend was being wasted on non-performing products — a major opportunity to recover and redeploy budget.
