The client

Marba Sport is a sporting goods wholesaler with over 30 years in business and a team of several dozen people. The core of the business is B2B wholesale: schools, clubs and shops, served through its own ordering platform and regional representatives. Alongside that, it has its own brands and exclusive rights to two foreign brands. On the retail side, it runs its own online shops and an Allegro account. Allegro is Poland’s dominant marketplace, the local equivalent of Amazon.

Where it started

A wholesaler this size holds stock in abundance. The bottleneck is the rate at which it can be sold. As our Head of E-commerce put it, large wholesalers “have so much stock they cannot grind through it”. A catalogue this large cannot be listed and maintained by hand. Every additional marketplace has its own product data requirements.

It came down to two things:

  • the catalogue is too large to list and update by hand,
  • the second channel needs a different data format from the first, so copying the offers across isn’t enough.

What we did

  1. We took over listings and offer maintenance on the client’s Allegro account.
  2. We launched and run Decathlon as a second sales channel on the same range.
  3. For the client’s own brand, Alpinus, we run sales on Amazon with A+ Content. This means an extended description section with graphics, a variant comparison and brand modules.

Results

On Allegro, around 80% of the products on the account are now live for sale. Decathlon, launched as the second channel, already carries an active range equal to 61% of the Allegro one.

Both channels run on a single catalogue and a single data back end. Widening the range in one does not mean rebuilding the process from scratch in the other.

What this means for you

At wholesalers and distributors, the bottleneck is often the sheer number of items to handle. When you have tens of thousands of SKUs and one channel with only a few per cent of them listed, the limit is the process. The market usually waits.
