Connect Shopify to Every Tool in Your Stack
Klaviyo, Recharge, NetSuite, Gorgias, Rebuy, ShipStation: we integrate Shopify with every platform in your marketing, operations, and CX stack. Native when possible, custom middleware when needed.
The tools your business runs on, connected to Shopify
We have built integrations for brands of all sizes, from simple native connections to complex bi-directional middleware syncing millions of records.
Custom middleware,
built to last
Most Shopify app connectors work until they do not: rate limit errors, sync delays, missing fields, and zero support when something breaks at 2am. We build custom middleware that you own, a dedicated sync layer between Shopify and your ERP, WMS, or marketing platform, with full logging, retry logic, error alerting, and monitoring. When your integration breaks, you have the code and the context to fix it, not a third-party ticket queue.

Built on APIs that Shopify trusts
Every integration we build uses Shopify's official APIs and approved authentication patterns. No unsupported workarounds, no fragile screen scraping.
Integrations built to run without manual intervention
We build with the assumption that integrations will fail eventually. That is why every connection we build includes logging, retry logic, and alerting before go-live.
Audit Existing Stack
We review your current integrations, identify failure points, rate limit issues, missing fields, and manual workarounds so we know exactly what is broken and why.
Week 1Map Data Flows
We document every data point that needs to move between systems, which API triggers it, what transforms are needed, and what happens when it fails.
Week 1–2Connect & Configure
We build the integration using Shopify's official APIs and OAuth. Native when possible, custom middleware when needed. Full logging and retry logic built in from the start.
Week 2–6Monitor & Alert
We set up uptime monitoring, error alerting, and a dashboard so you know the moment a sync fails, not when your customer emails to complain about a missing order.
Week 6+Multi-App Integration Stack: Recharge, Okendo, Rebuy & Bulk Invite
Woxer's subscription, reviews, and personalisation tools needed to work as one cohesive system on Shopify. We integrated the Recharge subscription SDK into a fully custom storefront flow, wired Okendo review widgets for UGC and ratings at the PDP level, configured Rebuy for AI-powered recommendations and smart cart upsells, and connected UpSolite's Bulk Invite app for seamless customer activation at scale.
Custom API Bridge: TeeinBlue × SparkLayer with Locksmith Access Control
StickerCactus ran two powerful apps — TeeinBlue for product customization and SparkLayer for B2B commerce — that had no native connection. We built a custom middleware bridge to pass TeeinBlue customization data directly into SparkLayer's B2B cart, created an internal rep impersonation dashboard via the Shopify API, and wired Locksmith's API for dynamic product and menu visibility per wholesale account — all talking to each other without manual data entry.

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.
