We used Sparky to help build our website a few years ago. We recently had some technical issues with our site so we reached out to Sparky to see if they could help. The responded very quickly and solved the issue just as fast. Highly recommend them.
- Tannen'sStore build or redesignOct 1, 2025
We worked with Sparky on a full Shopify build for Tannens.com, migrating from a legacy system and making sense of our complex catalog of 20,000+ SKUs. Their team not only translated our vision beautifully but also elevated it with thoughtful design, smart development, and ongoing optimization. They also built complex integrations connecting our in-store POS and supplier fulfillment network directly into Shopify, which has been a game-changer for our operations. We’ve seen measurable improvements in site performance, customer experience, and conversions since launch. If you’re looking for a Shopify partner who delivers both creativity and technical expertise, Sparky is the one. Professional, innovative, and a pleasure to work with – we couldn’t recommend them more highly.
