CUSTOM SHOPIFY APPS

Custom Shopify Apps Built Around How Your Store Actually Works

When off-the-shelf apps don't fit your workflow, we build private or public Shopify apps that do — from embedded admin tools to full App Store-ready products.

Custom Shopify Apps Built Around How Your Store Actually Works
Overview

Apps built for your store, not a generic use case

Most stores eventually hit a workflow that no App Store listing quite solves — a custom pricing rule, an unusual fulfilment process, or an internal tool your team needs embedded directly in Shopify admin. That's where custom app development comes in.

We build both private apps for internal use and public apps meant for App Store distribution, using Shopify's modern app stack — Remix, App Bridge, and the GraphQL Admin API — so what we ship stays compatible as Shopify's platform evolves.

What We Do

Custom Shopify app services we deliver

From a single internal tool to a fully distributed App Store product.

Public & Private App Development

Full-stack Shopify app builds for internal operations or App Store distribution, using Shopify's modern app framework.

Admin & Embedded App UI (Polaris)

Embedded admin interfaces built with Shopify Polaris so your app feels native inside the Shopify dashboard.

App Bridge & OAuth Integration

Secure OAuth flows and App Bridge integration so your app authenticates and communicates correctly with Shopify.

Shopify Webhooks & API Integration

Real-time data sync using Shopify webhooks and the Admin API, connecting your store to external systems.

Subscription & Loyalty App Development

Custom subscription billing, loyalty points, and rewards apps tailored to your retention strategy.

App Store Submission & Maintenance

End-to-end App Store listing preparation, review support, and ongoing maintenance for API version updates.

Integrations
Shopify third-party integrations

Connect your Shopify store to marketplaces, ERPs and shipping partners so stock, orders and catalogues stay in sync.

Myntra Shopify integration

Selling on Myntra and running your own Shopify store usually means two catalogues, two stock counts and orders keyed in by hand. A custom integration keeps one source of truth.

  • Product and catalogue sync from Shopify to Myntra listing formats
  • Inventory sync both ways, so a sale on one channel updates the other
  • Myntra orders pulled into Shopify for one fulfilment workflow

Myntra gives API access to approved sellers through its partner programme. Where API access isn't available for your account, we automate Myntra's bulk upload files instead.

Shopify marketplace integrations: Amazon, Flipkart and more

The same pattern works for other marketplaces: Amazon through the Selling Partner API and Flipkart through its Marketplace Seller APIs.

  • Channel-specific pricing and listing rules
  • SKU mapping when marketplace and store SKUs differ
  • Sync logs and alerts, so a failed update never goes unnoticed

Shopify ERP, CRM and logistics integrations

Custom apps that connect Shopify to the systems that run the rest of your business, through webhooks and scheduled sync jobs with retry handling.

  • ERP: Odoo, SAP Business One, Tally, Zoho Inventory
  • CRM: HubSpot, Zoho CRM, Salesforce
  • Shipping: Shiprocket, Delhivery and courier aggregators

Why a custom integration instead of an App Store connector?

Off-the-shelf connectors work until your catalogue has variants, bundles or channel-specific prices they can't model. A custom app follows your rules, runs on your infrastructure and has no per-order fee.

How we build a custom Shopify app

A structured process that keeps custom apps stable through Shopify's frequent API changes.

01 — Discovery

Workflow Mapping

We map the exact workflow your team needs the app to solve, including edge cases existing apps don't cover.

02 — Architecture

API & Data Design

We design the data model and choose the right Shopify APIs — Admin, Storefront, or Functions — for the job.

03 — Build

Development & Testing

The app is built in a development store first, tested against real scenarios before touching production data.

04 — Launch

Deploy & Maintain

We deploy to production and monitor for API deprecations, keeping the app compatible as Shopify updates.

Why Nepras

Why teams choose Nepras for Shopify apps

Building on Shopify's app platform requires staying current — here's how we do that.

Built on Shopify's current app framework

We build exclusively on Remix and the latest Admin API versions, avoiding deprecated patterns that break after platform updates.

App Store review experience

Having taken multiple apps through Shopify's review process, we know the common rejection reasons and design around them upfront.

Built for your actual workflow

We start from how your team works today, not a generic template — so the app fits without forcing process changes.

Proactive API version maintenance

We monitor Shopify's API release notes and update your app ahead of deprecation deadlines, not after something breaks.

Sprint
Working demos at every milestone
You review real software, not status updates
Docs
Documented, maintainable code
Handover notes so any competent developer can pick it up
OWASP
Security reviewed before launch
Auth, data handling and dependencies checked against OWASP guidance

Questions we get often

Have a specific question? Talk to us directly →

Should we build a private app or a public App Store app? +
If the tool is only for your own store, a private app is faster and cheaper. If you plan to sell it to other merchants, a public app requires additional work for billing, OAuth, and App Store review.
How long does App Store review usually take? +
Initial review typically takes 5–10 business days, though it can take longer if Shopify requests changes. We design apps upfront to reduce the chance of rejection.
Can you integrate our app with our ERP or CRM? +
Yes — we regularly connect Shopify apps to external systems like ERPs, CRMs, and fulfilment platforms through custom API integrations.
What happens when Shopify updates its API? +
We monitor Shopify's API version release notes and update your app ahead of deprecation deadlines as part of ongoing maintenance.
Do you provide support after the app is live? +
Yes, through our ongoing maintenance retainer, which covers bug fixes, API compatibility updates, and small feature additions.
Can you integrate Shopify with Myntra? +
Yes. We build custom integrations that sync catalogue, inventory and orders between Shopify and Myntra. Myntra gives API access to approved sellers through its partner programme; where API access is not available for your account, we automate its bulk upload files instead.
