Jim was very quick to respond to all of my questions, providing excellent customer service. His site design is fresh, fun and very easy to adapt to my product offerings. I would not hesitate to recommend him to other stores looking to make their site design more impressive.


We have ran a successful Etsy business for several years and decided to migrate to Shopify. We decided to go with an expert to be sure the shop was set up right. Honestly, it was very overwhelming to attempt to set up our own store. Shopify is a lot different than Etsy. I made the request for help and had several experts approach me. I spoke with each but went with Jim from Important Labs because I felt like he understood what we wanted. He had a very helpful and confident vibe. After hiring Jim and his company, I immediately felt so much less stress. I knew he could do it. He was outstanding. He never made me feel old or 'less than' when explaining things. For me, that was very important. He was always friendly and relaxed when answering my multitudes of questions. He offered great suggestions, too. I trusted his experience and he did not let us down. He not only set up our site but taught me how to use it so that I may run our business with confidence. Our site looks beautiful and functions exactly how we wanted it to function. We are so glad we went with Important Labs. and would do it again in a heartbeat.


Jim was wonderful. Highly recommend


Jim has been super helpful. He’s actually continued to monitor the work he’s done for my store to make sure it’s been performing. He’s quick and always available with any questions during and after the job. I will definitely recommend Jim and his team.

Aqua Burns Galleria

Working with Jim has been amazing. He clearly wanted to make my site as good as I wanted it to be. The job became a rush job when I booked a trade show at the last minute and needed the site up earlier than expected. Jim was still working on it on Sunday evening before the launch to have everything live in time.
Jim also worked on my email templates and cleaned up my email lists and set up 3 templates for me. My email marketing was all over the place because I couldn't find a design that worked for my customers.
Now I have a great site, with a much better theme. It loads quickly and has the right feel for my yoga customers.
At one point Jim called me a perfectionist...Look whose talking!
Thanks Jim. xx

First class service from beginning to the website handoff! I've worked with many web developers, and this experience was by far the best. Important Labs took the time to listen and understand my vision and business objectives for the website. The package was very comprehensive, and handled the majority of what I needed. The extra customizations that I wanted were greeted with a "Yes, I can do that", and was handled with care. I'd gladly recommend Important Labs to my friends and colleagues...actually I already have =)
