ottimo e buon servizio. una gran piattaforma per collegare tutti i marketplace. non ho collegato la gestione del inventario ne i pagamenti ne spedizioni. ho utilizzato solo la migrazione ed è super ottima.
Buena aplicación, facil de usar. Aparecen todos los pedidos de todas las plataformas en una misma pagina con lo que hace que todo sea mas rapido y facil de gestionar. La atención al usuario es muy buena, son muy amables y te ayudan con todo. Recomendado al 100%
