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.
“I highly recommend the app. Very simple to use and does the job. After a day I see people increasing deals to get free shipping. And thanks to Tomer from customer service who is always there when needed ”

“I use this for Twitter ad tracking. What's the point of running Twitter ads, if you can't track the performance on your Wix site? This app does the trick!”

“We're using the advanced plan, Tomer from Presto-Changeo has been beyond helpful in working with us to make sure we get the data we need from Wix to Klaviyo. Amazing customer service, we're super happy and now ready to take over the world with Klaviyo.”

“I had a couple of issues at start, but they provided an amazing support and help to make it works. It does exactly what I should do and it’s a huge time and error saver to manage the bundles.”

“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
“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.”

“Before this app I was having trouble placing embedded Klaviyo forms in the footer of my Wix site. Not only did this app have the answer to my issues, but the team a PoCo walked me through installing it and making sure my forms work! Highly recommended.”

“Absolutely love the Stamped app!!!!!! After converting from Shopify to Wix, it was hard finding apps that offered the same functionality as my old store until I decided to give Stamped a shot. After communicating with some of the amazing customer service reps and spending some time learning the app, I am highly pleased!!! I actually like it better than the app I was using on my old store. You guys are the best!!!!!”
