IN SHORT

Shopify app development is building custom private apps — discount engines, admin tools, automated workflows, API bridges — when the App Store doesn't have what your business needs. We build on Remix and Node.js (Shopify's official stack), hand over full source code, and typically ship in 2–6 weeks.

Overview

The Shopify App Store has thousands of apps — but the more complex your business, the more likely you'll hit a wall. We build private Shopify apps using Node.js and Remix (Shopify's official framework) that extend the platform exactly how you need it. Whether it's a custom discount engine, a supplier feed importer, an automated fulfilment workflow, or a bespoke admin panel — if it can be built on Shopify's API, we'll build it cleanly and maintain it.

AT A GLANCE

Timeline2–6 weeks
CategoryCustom Apps

Who is this for?

  • Stores whose workflow needs don't exist in the App Store — or exist only as bloated apps doing 10% of what you pay for
  • Businesses with suppliers, systems, or data feeds that have no off-the-shelf Shopify connector
  • Plus merchants who want Shopify Functions for custom discount, payment, or delivery logic
  • Teams drowning in manual admin work that a webhook-driven automation could eliminate

What's included

Custom Shopify app built on Remix + Node.js
Shopify Admin API and Storefront API integration
Shopify Functions (discounts, payment, delivery customisation)
Webhook-driven automation and event handling
Custom admin UI using Shopify Polaris
Private app installation and store integration
Full source code handover
Documentation and handoff walkthrough

Our shopify app development process.

  1. Step 1

    Requirements & feasibility

    We map what you need against Shopify's API surface and tell you plainly what's buildable, what's not, and what already exists.

  2. Step 2

    Technical spec

    A written scope — data flow, admin UI, API contracts — agreed before development starts.

  3. Step 3

    Build

    Remix + Node.js on Shopify's official app framework, with Polaris admin UI so it feels native to your team.

  4. Step 4

    Testing & installation

    Tested against production-realistic data in a development store, then installed as a private app on yours.

  5. Step 5

    Handover

    Full source code, documentation, and a walkthrough call. It's your app.

How pricing works

Fixed quote from the technical spec. Small automation apps sit at the low end; multi-system apps with admin UIs are quoted per feature set, so you can trim scope to budget.

Common mistakes to avoid

  • Paying monthly forever for a heavyweight App Store app when the one feature you need is a small custom build
  • Building on unofficial frameworks that break when Shopify's API versions rotate
  • Skipping the technical spec and discovering mid-build that the API can't do what was assumed
  • Accepting apps without source code handover, creating permanent dependency on the builder

I am a repeat customer of Amoni, and I couldn't be more pleased with the experience. The quality of the Shopify development and the overall project management has been exceptional—far exceeding that of many agencies I have worked with in the United States. I highly recommend Amoni to anyone seeking high-quality, professional Shopify development at a reasonable price. Their communication, responsiveness, and speed of delivery are outstanding and comparable to what you would expect from a top-tier agency charging ten times as much. Amoni consistently delivers excellent work, on time and with great attention to detail. I look forward to working with them again on future projects.

I spent the last 10 days building my Shopify website from scratch with zero background and kept running into issues. Every time I touched the code, something broke, and I was honestly feeling defeated. I came across his profile, reached out, and within one hour he had everything fixed and running perfectly. I can't explain how relieved and happy I felt. I'll definitely be working with him again as we continue improving our website.

We hired him to make some CSS changes to our Shopify site, something we were unable to do ourselves. He took on the task immediately and completed it in record time, significantly improving the user experience on our site. We are also collaborating with him on other projects, and I can confidently say that there are very few providers who are as professional, fast, and proactive as he is. Highly recommended!

Working with Anil was one of the best experiences I've had. I've worked with other developers before, but no one has been as dedicated. He worked day and night to finish my website – sometimes with barely any sleep. I sent him a document with my ideas, and he delivered much more than expected. I had many extra requests, and he fulfilled them all without a single complaint. You can tell he truly loves his work. For this amazing job, I'm giving him a $100 bonus. If you're not working with Anil, you're seriously missing out! This Guy is crazy

I have a basic level of liquid coding for shopify and after 6 hours of trying to do my task, gpt told me to give up and hire a pro. He did it in less than 24 hours for a great rate.

I'm glad to get help on changing the cart into a Pokeball once again. It adds a nice touch. I couldnt get the color scheme right on my own. He made the color scheme according to my logo colors. It made the website look more complete.

I recently worked with Amoni and couldn't be happier with the experience. From the very start, their communication was clear, prompt, and courteous—they took the time to understand exactly what I needed and offered thoughtful suggestions to make the final product even stronger. The delivered work exceeded my expectations in every way. The quality was exceptional: every detail was polished, and it was obvious a great deal of care and expertise went into the project. The final files arrived ahead of schedule, perfectly organized and ready for use. Most impressively, Amoni maintained the highest level of professionalism throughout. They responded to revision requests quickly and gladly incorporated my feedback until the end result was exactly what I envisioned. I would wholeheartedly recommend this gig to anyone looking for top-tier results and a hassle-free process. I'll definitely be turning to them again for future projects!
