Ratings and reviews

• razzmatazzProduct and collection setupMar 20, 2025

  Always responsive:)

• TrueluxeStore build or redesignAug 6, 2018

  I worked with Michael and Dillion over the course of our project. They were excellent to work with and we were able to get a design that we loved. We haven't launched yet because we're deep in the production of product photography but everything has gone smoothly during the entire project. I would highly recommend these guys over anyone else simply because of how well they plan and execute. Everything is delivered on time and they really go the extra mile to make sure the site that is delivered meets a rigorous standard.

• TRUBRANDSStore build or redesignJul 12, 2018

  We had a different vendor who originally set up our Shopify store and thought that they did a good job. After being introduced to Sellry and seeing what they could accomplish with the same platform, we now know what a "great" job looks like! The Sellry team improved purchase flow and were able to resolve a Shopify to Netsuite issue that both vendors said was impossible to remedy. I personally interacted with the Sellry team and found them responsive and efficient. I would recommend Sellry to anyone who wants to get the most out of their Shopify site.

• Floor CitySEOMay 24, 2018

  Michael, Willem and Juan have been amazing. Our homepage, header and mobile menu are state of the art now they've put their touch on it. I highly recommend Sellry for all your web development and design.

• Wanderer BraceletsStore build or redesignJan 4, 2018

  The Sellry team has performed above our expectations both in technical knowledge and in taking the time to understand our needs and providing spot-on solutions. Having a development partner that can operate as the linchpin between our marketing agencies and our creative team has allowed us to operate in a more stream-lined and effective manner.

• PreStore migrationJan 4, 2018

  We worked with Sellry to launch our Shopify Plus store and are thrilled with the results. Our launch included a migration of our existing site, design changes, adding a range of capabilities, and making many adjustments with tight deadlines. All was completed accurately and on time. Sellry is highly skilled and very responsive--we look forward to working them further in 2018!

• REDACTEDStore build or redesignDec 6, 2017

  Sellry was able to help us execute the changes needed for both the front end and the back end on our site and was even suggested apps to help make our life's easier with building the site as well as keeping up with analytics with the site going forward. They were super responsive and always there when we needed them. I look forward to working with them again in the future!

• www.bellavitabags.comStore build or redesignApr 11, 2017

  Our seo company recommended Sellry and, although we were a bit uncomfortable with paying 100% upfront, we could not be more pleased with their pricing, communication, expertise, and ability to deliver two websites that interacted (wholesale/retail) much faster than other quotes. They exceeded our expectations and this was the best website development experience we've had in our 15 years (5 prior sites). I would highly recommend them and be happy to provide additional references on their behalf.
