Ruby on Rails Development & Shopify Integrations
Custom Ruby on Rails applications and services -- including the backend logic and integrations that power advanced Shopify stores beyond what off-the-shelf apps can do.
Ruby on Rails Services
Custom Rails Applications
Full web applications built on Ruby on Rails -- admin systems, internal tools, customer portals and SaaS products.
Shopify + Rails Integrations
Dedicated Rails services that connect to Shopify through its Admin, Storefront and Partner APIs for custom business logic.
Custom Shopify Apps in Rails
Embedded and standalone Shopify apps built on Rails, following current App Bridge, OAuth and Billing API standards.
Background Jobs & Automation
Sidekiq/ActiveJob-powered workers for syncing orders, inventory, pricing and fulfilment data reliably at scale.
API & Webhook Architecture
RESTful and GraphQL APIs plus resilient webhook handling for real-time data flow between systems.
Legacy Rails Upgrades
Upgrading older Rails applications to current, supported versions safely, with test coverage along the way.
When Shopify Apps Aren't Enough
Shopify handles catalog, cart and checkout extremely well, but once a business needs custom pricing logic, multi-party approvals, complex quoting, or a workflow that spans several systems, that logic is often cleaner and more maintainable as a dedicated Ruby on Rails service talking to Shopify through its APIs -- rather than stretching a single app past what it was designed for.
- Custom pricing, discounting & quoting engines
- Multi-step approval and fulfilment workflows
- Multi-vendor / marketplace order logic
- A clean separation between commerce and business logic
Keeping Shopify in Sync With the Rest of Your Business
Most Rails-behind-Shopify projects come down to one problem: keeping data consistent across systems as orders, inventory and customers change constantly. We build background job pipelines and webhook listeners designed to handle retries, rate limits and partial failures gracefully, so a dropped connection never means lost data.
- Sidekiq / ActiveJob background processing
- Shopify webhook verification & idempotent handling
- ERP, WMS and accounting system sync
- Rate-limit-aware Admin API usage
Where This Combination Shines
B2B Quoting & Approvals
A Rails app manages multi-step quote approvals and custom pricing rules, then pushes finished orders into Shopify.
Multi-Vendor Marketplaces
Rails coordinates vendor onboarding, commission splits and payout logic around a Shopify storefront.
ERP & Inventory Sync
A Rails service keeps stock levels, pricing and product data in sync between Shopify and your ERP in near real time.
Technologies We Work With
We Also Build Standalone Ruby on Rails Applications
If your project doesn't involve Shopify at all -- a new product, an internal tool, a SaaS platform or an existing Rails codebase -- see our general Ruby on Rails Development page.
From Scoping to a Reliable Integration
Map the Data Flow
We identify exactly which systems need to talk to Shopify, and what triggers each sync.
Architect the Service
A Rails application designed around your business logic, not around Shopify's data model.
Build & Test
Development with automated tests covering webhook edge cases, retries and failure handling.
Launch & Monitor
Go-live with monitoring in place so sync issues are caught immediately, not discovered by a customer.
If your requirement fits within what an existing or custom Shopify app can do, that's usually the faster and cheaper route -- see our Shopify Development page. A dedicated Rails service makes sense once the logic spans multiple systems or goes beyond what an app's architecture comfortably supports. We'll tell you honestly which applies during scoping.
Yes, including upgrading older Rails versions, improving test coverage, and extending existing Shopify integrations.
Our background job architecture is built around Shopify's rate limits from the start -- queuing, backoff and retry logic are standard, not an afterthought.
Yes -- we can deploy and manage it on AWS as part of our Cloud & DevOps service, with monitoring and ongoing support.
