About us
About us
Founded in the bustling heart of New York City in 2009, Presto-Changeo emerged as a boutique ecommerce agency committed to crafting exceptional, high-performance modules and apps to enhance ecommerce experiences globally. Together with our full-service design and development partner, EIP Concepts CA, Inc., we've cultivated a rich tapestry of expertise in all facets of ecommerce. Now based in California, we pride ourselves on our long-standing history, global reach, and trust that we've fostered with our clients over the years. Entrust us with your ecommerce needs, and we'll transform them into solutions that drive productivity, enrich features, and elevate your online shop to new heights.
What we do
PrestaShop was where our journey began, developing dynamic modules, crafting bespoke websites, and actively supporting the PrestaShop community in its forums. Our founder and lead developer, Tomer (tomerg3), not only moderated these forums but also contributed to the technical review of "PrestaShop 1.3 Beginner's Guide" by Packt Publishing.
After a transformative 12 years committed to PrestaShop, we have pivoted towards SaaS (Software as a Service) with the Wix platform. This transition allows us to simplify app usage, streamline installations, facilitate updates, and provide tools to enhance your Wix site, enabling seamless third-party service integrations and leveraging proven methods to boost sales.
Our expert design and development team, operating under the EIP Concepts CA, Inc. banner, is adept at crafting tailored solutions to cater to your specific ecommerce needs. From creating distinct B2B sites to hyper-local shops with precision targeting, we've done it all.
Our philosophy is simple: to build a company we ourselves would love to collaborate with. We strive not only to meet your expectations but to consistently exceed them, with exceptional customer support, stunning user experiences, and top-tier quality work.
What sets us apart? Our unrivaled, top-quality apps and a US-based customer service team that goes above and beyond to ensure your satisfaction. Trust us with your ecommerce journey, and we'll turn it into an exceptional success story.
Highest quality apps & US based customer service set us apart!

about us on the Wix Marketplace.

“Great app and support. We had to disable the script to stop the reviews showing on our website (which is a button and easy). We're happy and everything is working well.”
— Tane48

“I have been trying to solve an issue for over 12 months. Poco not only solved the problem but offered responsive tech support. Forget all the zapier automations and install this app.”
— Artsinthevalley

“It makes a big difference indeed when you are in need of a tool to edit products. Fact: thanks to this app i have managed to edit approx. 600 products in three days. There is no other means to help you in editing the products with such efficiency. Great support as well when in need or if any doubts.”

“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

“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.”

“I installed this app and was surprised just how easy it was to set up. I had some initial issues on Pinterest side but the app support for wix has been outstanding as they were responsive and provided ongoing assistance. I definitely recommend this app for easy conversion tracking.”
— Katealexander72

“FINALLY I found an app that connects my Wix Store to Mailchimp! It syncs perfectly and the customer service is spot on! LOVE IT!”
— Pauline0187

“The product is pretty straight-forward. There are some quirks in the way it interacts with products that have variants that was driving us a bit crazy until we reached out for help. We reached out on a Sunday and weren't expecting to hear anything but got a reply with in the hour! After a bit of back and forth Tomar helped walk us through what we were doing incorrectly and even provided videos he created just to show us how we should set everything up. Al I can say is WOW! I only wish this level of support was available with all of the Wix apps we've used.”
