Korf Audio GmbH review for Advanced PreOrder‑ ALL IN ONE

Sept. 16, 2022

I needed an app that would do both preorders and partial payment. Tried a dozen apps, and all were deficient in some way. Advanced Pre-Order is a lot more polished than most preorder apps, has simple straightforward pricing, and the support I got from Vipin is just amazing. Never had to wait more than an hour for a reply, questions were promptly and courteously resolved—all that before I paid them a single penny! I'm a happy paying customer now.
