Partners are tiered based on multiple factors, including their history of experience and proven success on Shopify.
Specialized services
Starting at $500
Description: Custom sections, layout and design changes, product and variant page behaviour, app conflicts, mobile and cross-browser fixes. We work on live themes without breaking what already works, and test on every device before shipping. Turnaround 1-3 business days, urgent fixes often same-day. Our most reviewed service: 105 merchants have rated it. Fixed quote before we start, 14 days of follow-up.
Starting at $300
Description: Layout bugs after a theme or app update, 404s, checkout errors, subscription and Recharge issues, leftover code from a previous developer. Most inquiries answered in 30 minutes; urgent breakages often diagnosed the same hour. AI-assisted analysis locates the fault fast, a senior developer confirms and fixes it, and you get a plain explanation of the cause. If we can't solve it, you don't pay.
Starting at $5000
Description: Custom Shopify and Shopify Plus builds, from your designs or from scratch. Online Store 2.0 architecture, performance-first engineering, merchandising logic built around how your catalog actually works. Large catalogs, multi-dimensional filtering, B2B storefronts, multi-region setups, high-AOV considered purchases. Includes discovery, QA, launch support and handover so your team can edit content.
Starting at $4000
Description: Private and custom Shopify apps for what no store app does properly: subscription logic (Recharge and native), bundle builders, product configurators, checkout extensions, B2B ordering, inventory systems, quiz and finder tools. Also ERP, OMS, PIM and 3PL integration - NetSuite, SAP, Dynamics, Acumatica or custom middleware. Built with proper auth, webhooks, error handling and documentation.
Starting at $2500
Description: Conversion work grounded in your store's data, not a generic checklist. We find where you're losing people - product page, cart, checkout, mobile - and tell you what's worth fixing before touching anything. Product page architecture, bundle and upsell logic, checkout flow, speed, A/B testing to prove the change worked. You keep the prioritised audit whether or not you hire us to build it.

5We reached out to OUXP to help us with our conversion rate on our website and he went above and beyond.

He was efficient and speedy. Could not recommend him more.

They didn’t just patch things - they tracked down the real root causes, cleaned up our theme and got all the key apps working together smoothly. The store works faster, more solid, and we’re seeing a clear bump in conversions. Communication was sharp, honest and always on time. If you need ...
