About us
About us
Presto-Changeo was founded in New York City back in 2009, as a small boutique ecommerce agency that develops unique and high-performance modules & apps that boost productivity, add features and improve ecommerce shops around the world. Along with our full-service design and development agency EIP Concepts CA, Inc., we are seasoned experts in all things ecommerce. Currently headquartered in California and delivering solutions worldwide.
What we do
We started our way with the PrestaShop platform, developing modules, creating custom websites, and supporting the PrestaShop community in the forums where Tomer (tomerg3), our founder and lead developer, is a moderator. He also provided technical review for “PrestaShop 1.3 Beginner’s Guide” by Packt Publishing.
After nearly 12 years developing for the PrestaShop platform, we have decided to transition away from open source into SaaS (Software as a Service) with the Wix platform, which allows us to simplify the use, installation, and updates of our apps, as well as deliver tools to streamline your Wix site, connect it with 3rd party services, and enhance its functionality with proven methods that increase sales
Our development and design team working under the EIP Concepts CA, Inc. name is highly experienced in creating customized solutions for our client's ecommerce needs. We have developed unique B2B sites, highly targeted hyper-local shops, and everything in between.
We are trying to build a company we’d like to do business with ourselves. We aim to amaze you through our support and outstanding user experiences in addition to the quality of our work.
Highest quality apps & US based customer service set us apart!

about us on the Wix Marketplace.
“This is a great App and really easy to use! I would like it even more if there were a few more customisable options. It would be really handy if you could position where it said how many you have in stock. But other than that its a really great app.”
— Abuckenham
“The app does what it is supposed to do. Would be nice to see more features for placement of the bar, but overall no issues. Customer service was great. Thank you.”
— Charliefinch
“I love the product discount planner app because it was slightly annoying having to manually do the discounts. I remember on our last sale I literally had to go through each product to change the pricing back to normal, it was so irritating & time-consuming. Plus I had almost forgot to change it back to regular pricing so I feel this app definitely brings value in helping us to schedule product discounts and manage our sales more efficiently!”
— Herbalhealingnation
“Tomer went above and beyond to help me sort out the problem I was having due to user error. Now that I know how to create collections correctly, it is working perfectly.”
— Mikaelaacidlake
“L'applicazione è molto intuitiva e funzionale. Permette di creare dei flussi di email molto utili sia per la realizzazione di un funnel di vendita sia per semplici campagne di email marketing. Nel caso si avessero problemi con l'integrazione l'assistenza è sempre disponibile ad aiutarti e risolvere i tuoi problemi. Consigliata!”
— Riccardomutti
“Relatively simple to set up and both the PoCo and Stamped.io teams have been fantastic at responding to queries whilst I get going. Thanks!”
— Annabriscoe
“Wix has serious deficiencies when trying to track conversion events for 3rd party ad platforms, so this app helps to fill that void. Excellent customer support with my questions, and they were quick to patch in fixes when needed.”
— Datpham1
“I've had to add bundles and bundles with variants for all my holiday sales, since Wix doesn't support the type of coupons and discounts I wanted to offer. This app has made it SO easy. I just add a new product to Wix (with or without variants) and then go over to the Bundles App and tell it what products belong to the the new product and BOOM, it's taken care of! Perfect. Thank you.”
