We design and build Shopify themes using custom Liquid and OS 2.0 section schemas. Stores that score 90+ on PageSpeed, load instantly on mobile, and turn browsers into buyers from day one.
Trusted by growing Shopify brands
From your first product page to post-purchase, here is what a Shopify theme project with UpSolite actually covers.
Product pages built around your buying journey. Sticky ATCs, variant selectors, tabbed content, subscription options, and custom upsell blocks. The Woxer PDP we rebuilt lifted add-to-cart rate immediately after launch.
Slide-out carts with free shipping progress bars, bundle upsells, gift-with-purchase logic, and express checkout buttons. No app required, fully owned code that loads in milliseconds.
Tiered discount logic, BOGO rules, bundle builders, and gift-with-purchase triggers. For Woxer we replaced three separate promotion apps with one clean custom solution that runs faster and costs less.
Lighthouse 90+ on every theme we ship. We audit, refactor, and rebuild: lazy loading, deferred scripts, Liquid render time fixes, and image pipeline setup that sticks.
Moving from a legacy theme, Debut, Brooklyn, or a page builder? We migrate to Online Store 2.0 with full section schema, metafield bindings, dynamic sources, and app block support.
Gift messaging, trust badges, loyalty redemption, and upsell widgets built inside Shopify native checkout. No hacked scripts, no compliance risk, no lost sales.
Woxer came to us with a slow store, three conflicting promotion apps, and a product page that wasn't converting. We rebuilt everything from the ground up: a custom PDP with Recharge subscription integration, a bespoke cart drawer with free shipping bar and upsell logic, and a single global offer engine that replaced all three promo apps with one clean Liquid solution. Subscription engagement improved significantly and conversion lifted in the first week. The whole project was delivered in 8 weeks.

Every Shopify theme project follows the same four-stage process. You see progress at every step and nothing goes live until you sign it off.
Discovery & Audit
We audit your existing store, Lighthouse scores, Liquid code, and conversion data to map exactly what is slowing you down or costing you sales.
Week 1Design & Architecture
We design the theme structure, section schemas, metafield bindings, and UX patterns. You see the approach before a single line of code is written.
Week 1–2Build & Test
We build in short sprints with staging previews and QA on real devices. Performance benchmarks are hit before anything touches your live store.
Week 2–7Launch & Handover
We go live, monitor the first 48 hours, and hand over documentation so your team can update the theme confidently without developer support.
Week 7–8"We’ve had a great experience working with this ecommerce agency. The team is professional, responsive, and highly skilled in development. They understood our requirements quickly and delivered high-quality work that improved both the functionality and performance of our store. Highly recommended for anyone looking for a strong ecommerce development team."
"They've helped out with emergency fast fixing and full rebuilds of high-traffic e-commerce brands without ever an issue - they match submitted designs and never deliver with any bugs. They're also incredibly affordable for small, independent businesses. Highly recommend this team and have passed them to work with several colleagues."
Works exactly as per brief and design, always delivers work on time and are Shopify experts. I’ve found that other devs I’ve worked with have had trouble keeping deadlines and weren’t able to make the website look the way that I had specified it in Figma. No such issues with Upsolite. They are extremely reliable. Highlty recommended.
