        Reviews from professionals across Europe, trusted voices from the shelves.

        • We’ve been working with Xtra for over a year now, and the experience has been nothing short of excellent. From the start, their team took the time to understand our store's profile and helped us build the perfect product assortment. Orders arrive quickly, the packaging is retail-ready, and our customers love the quality. It’s rare to find a supplier that combines efficiency with such a personal touch.

          5/5 Sophie, Owner (NL)

        • Xtra feels less like a supplier and more like a partner. We appreciate how easy it is to reorder, and how well the product photos and descriptions are made for online use, a huge help for our webstore. Their advice on bestsellers and seasonal trends has helped us improve our sell-through rate significantly. Highly recommended for any pet retailer looking for quality and consistency.

          5/5 Marco, E-commerce Manager (DE)

        • As a grooming salon, we don’t carry a massive inventory, so having a reliable supplier like Xtra is a game changer. We love that we can order small volumes and still get fast delivery and great service. are a big hit with our clients. Plus, their B2B portal is super intuitive and saves us time every week.
