“In comparison with other tools and solutions we’ve seen, Nextail is the easiest to use and is much more user-friendly. You can clearly understand what you’re doing and the impact of your choices which helps to optimize results. Other solutions we’ve seen can actually make things more complicated and confusing, making you less prone to want to use it. That’s not the case with Nextail.”

– Luis Miguel Varo Mesa, Director of Planning & Distribution for Hoss Intropia, Cortefiel, Pedro del Hierro at Tendam

“It was imperative that our backroom processes were as robust as possible but also offered great agility because delivering a perfect customer experience is only as good as the operations that support it. This is why we selected Nextail. Offering more than best-in-class merchandise planning, they also provide the synergies between the high-efficiency world of fast fashion and the curated world of luxury that we need the most.”

– Silvia Zunino, Head of Merchandising at Valextra
