To pick a Shopify app agency in Kerala, decide what kind of app you need before you look at agencies. That means a custom app for one store, a public Shopify App Store app, or an integration with your ERP, CRM or POS. Then shortlist the agencies whose own pages show that kind of work. The names worth checking on any Shopify app development agency in Kerala shortlist are Intertoons (Kochi), Chainzent (Trivandrum), Globosoft (Kochi), Ormeon (Kochi) and Seamedia (Malappuram). Final Apps also turns up in searches, but we could not confirm who it is.
This guide is for merchants, D2C brands and startups in India, the UAE and further afield who need custom Shopify app development or Shopify integration services in India. Disclosure: Seamedia publishes this guide and is one of the agencies compared. From here on we refer to it in the third person and treat it by the same rules as every other agency.
The short answer: choosing a Shopify app agency in Kerala
Pick the agency that has already built your type of app. A custom app or integration needs strong API and integration skills. A public App Store app also needs experience with Shopify review, billing and privacy rules. Shortlist two or three agencies, check their Shopify Partner Directory listings, ask for live examples, and get a milestone-based quote that names who owns the code.
What Shopify app development actually covers
“Shopify app development” covers at least seven different kinds of work. An agency can be strong at one and weak at another, so name the one you need before you ask anyone for a quote.
The main app and extension types
- Custom (private) apps: built for one store or organisation. They skip App Store review and usually handle internal workflows, data syncs or features specific to one merchant.
- Public App Store apps: sold to many merchants. Shopify’s developer documentation sets out the quality bar. Public apps must meet App Store requirements, bill through Shopify’s billing system and respond to the mandatory privacy webhooks. Embedded admin apps generally use Shopify App Bridge.
- Theme app extensions: app blocks that merchants add through the theme editor, so nobody has to edit theme code.
- Shopify Functions: server-side logic for discounts, delivery options, payment method rules and cart validation.
- Checkout UI extensions: custom blocks in checkout and on the thank-you and order status pages. How much of checkout you can change depends on your plan.
- Integrations: custom ERP and CRM Shopify connectors, POS sync, couriers and payment gateways. Most Indian mid-market projects are this kind of work.
- Headless (Hydrogen) integrations: custom storefronts built on the Storefront API, either with Hydrogen or with a framework like Next.js.
The tooling a competent team should mention
New Shopify apps usually start from Shopify CLI and Shopify’s official app template, use Polaris for the admin interface, and talk to the GraphQL Admin API. A team that builds apps should be able to explain API versioning, dev stores and access scopes without notes. If they can’t, ask to see a shipped app before you go further.
What non-Plus stores can and cannot do
You don’t need Shopify Plus to get a custom app. Stores on Basic, Shopify and Advanced plans can use custom apps for admin workflows and integrations. They can also use theme app extensions and checkout extensions on the thank-you and order status pages. The usual Plus-only areas are customising the information, shipping and payment steps of checkout, and running Shopify Functions from a custom app rather than a public one. Shopify changes these limits, so confirm them for your plan in its documentation before you agree a scope.
Custom app vs. App Store app vs. store build: which do you need?
Whether you need a private or a public app decides your budget, your timeline and which agency fits. Plenty of buyers pay for a custom app when an existing App Store app would have done the job.
| Your situation | What you probably need | Why |
|---|---|---|
| An existing App Store app already covers your core need | Existing app plus configuration | Cheapest and fastest, and someone else maintains it |
| Layout or design change on the storefront | Theme or store build work | Liquid and sections can handle it without an app |
| Orders, stock or prices must sync with ERP, CRM or POS | Custom app or middleware integration | It needs logic, credentials and error handling specific to your business |
| Custom discount, shipping or payment rules | Shopify Functions inside an app | Functions are deployed through apps |
| You want to sell the tool to other merchants | Public App Store app | Needs App Store review, billing and ongoing compliance |
For a public app, plan for the quality bar from the start. Shopify’s Built for Shopify requirements currently include at least 50 net installs from active shops on paid plans and five reviews, plus performance and design criteria. No agency can deliver those installs for you. What it can do is build to the technical standard from day one.
Shopify app development agencies in Kerala compared
How we checked: in November 2026 we read each agency’s homepage, its contact page where it had one, and up to four of its Shopify, app or service pages, found through site links and sitemaps. Everything in the table comes from those pages, so it is each agency’s own claim. We did not check Partner Directory, Clutch or GoodFirms profiles. Verify those yourself.
Shopify app development agency in Kerala: comparison table
| Agency | Verifiable services | Evidence of Shopify app work | Best for |
|---|---|---|---|
| Intertoons, Edapally, Kochi (contact page) | Calls itself a software, AI automation and Shopify Partner agency. Shopify partner page lists theme development, headless development and integrations. Also offers migration. | Integrations and custom Shopify development are listed. The pages we read don’t describe a public Shopify App Store app. | Kochi brands that want a store build, migration or headless project with integrations from one team |
| Final Apps | The web address our research found led to Apple’s App Store, which is not an agency website. | We could not confirm this agency’s identity or any Shopify app work. | No verdict |
| Chainzent, Trivandrum (homepage) | Shopify service page lists theme development, store setup, headless (Shopify + Next.js), Shopify app development, migration and maintenance. | Has a “Shopify App Development” heading. Its Mercora project describes a Shopify launch in Panama. | Headless Shopify on Next.js, or app development backed by a full-stack web team |
| Globosoft, Kochi (homepage) | Shopify page lists store design, theme development, iOS and Android commerce apps synced with Shopify, and CRM data flows. | Mobile apps connected to Shopify products, customers and orders. Publishes Shopify case studies. | Brands that want native iOS and Android shopping apps running on Shopify data |
| Ormeon, Kalamassery and Infopark, Kochi (contact page) | Digital marketing first (SEO, Google Ads, social). Shopify page lists custom store development, theme design, app integration and custom features, and migration. | “Shopify App Integration & Custom Features” is listed. Building public apps or Functions is not mentioned. | Merchants who want a Shopify store and paid marketing from the same agency |
| Seamedia, KINFRA Techno Industrial Park, Malappuram (contact page) | Kerala Shopify page lists custom app development and integration, Shopify custom API development, store setup, migration and SEO. | A dedicated Shopify ERP integration page that covers middleware and queue-based processing. | Stores that need ERP, POS or B2B pricing sync alongside a Shopify build |
What each site does and doesn’t say
Intertoons describes itself as a “Kochi-based Software, AI Automation & Shopify Partner Agency.” Its Shopify development page mentions custom sections, integrations and Cloudflare for security and speed. Its food delivery app page says it handles app store submission, but that page is about mobile apps, not Shopify ones.
Chainzent’s web development page lists Next.js, React, Node.js and GraphQL, all of which carry over to Shopify app work. Ask to see a shipped Shopify app, not only a store.
Globosoft says it is a Shopify Service Partner. Its app work is customer-facing mobile apps, which is not the same thing as embedded admin apps, so be clear about which one you are buying.
Ormeon says it is a Google Premier Partner, and its Shopify offer is built around store development and integration.
No agency’s pages show a shipped public App Store app. If you’re building a SaaS product for the App Store, ask every agency for a live listing.
Where Seamedia fits as a Shopify app development agency in Kerala
Seamedia describes itself as a Shopify development agency in India with 15+ years of experience. Its contact page lists an office at KINFRA Techno Industrial Park, Kakkenchery, Malappuram, Kerala, and a US entity, Seamedia LLC. Its services page lists Shopify app development, custom store development and ongoing support and maintenance.
Its most detailed app-related offer is ERP integration. That page describes a GraphQL-first approach to the Shopify API, syncing Shopify POS with an ERP, showing stock by location, and pulling customer-specific B2B pricing from the ERP. Merchants can also hire Shopify developers by the hour for new features, customisation and bug fixing.
Who it suits: merchants who need a store build or migration plus integrations or custom app logic. Where to look harder: founders building a public App Store product should ask Seamedia for shipped App Store examples, just as they would ask any other agency. Ask for its Partner Directory listing and relevant case studies on the first call. For more on scope, see Seamedia’s Shopify custom app development and integration services.
8 criteria to evaluate any Shopify app agency
- Shopify Partner status. Search the Shopify Partner Directory. A listing doesn’t prove the agency can build apps, but if there isn’t one, ask why.
- App-specific proof. Ask for a live App Store listing or a working custom app on a dev store. A portfolio of stores doesn’t prove app engineering.
- Current stack. Shopify CLI, the official app template, Polaris, the GraphQL Admin API, App Bridge, Functions and checkout UI extensions.
- Security and data. Access scopes, protected customer data, privacy webhooks, and GDPR or India DPDP obligations.
- QA and App Review support. Do they test on dev stores across plans? Have they had an app rejected in review and fixed it?
- Integration architecture. Queues, retries, API rate limits and one system of record.
- Ownership. Who owns the code, the repo, the Partner account and the hosting? Get the answer in writing.
- Post-launch support. Shopify releases API versions on a regular schedule. Ask who upgrades your app before your version is retired.
Cost of custom Shopify app development in India
The bands below are illustrative estimates, not quotes from any agency named here. They assume a blended rate of ₹1,500 per hour. Real Indian quotes can sit well above or below that, so swap in your own rate.
| Project type | Effort (hours) | Illustrative cost at ₹1,500/hr | Typical timeline | Source |
|---|---|---|---|---|
| Razorpay or Shiprocket custom workflow (beyond the standard apps) | 40-120 | ₹60,000-₹1,80,000 | 2-4 weeks | Estimate |
| Small custom admin app (one workflow) | 60-150 | ₹90,000-₹2,25,000 | 2-5 weeks | Estimate |
| Shopify Function or checkout extension | 40-120 | ₹60,000-₹1,80,000 | 2-4 weeks | Estimate |
| Tally or Zoho Books/Inventory connector | 120-300 | ₹1,80,000-₹4,50,000 | 1-3 months | Estimate |
| Larger ERP or CRM connector with middleware | 200-600 | ₹3,00,000-₹9,00,000 | 2-4 months | Estimate |
| Public App Store app (MVP with billing) | 300-800 | ₹4,50,000-₹12,00,000 | 3-6 months including review | Estimate |
Worked example with GST
Use this formula: hourly rate × hours × 1.2 (a buffer for QA and change requests), then add 18% GST. A 200-hour Tally connector at ₹1,500 per hour comes to ₹3,00,000. The 20% buffer takes it to ₹3,60,000, and GST at 18% brings the total to ₹4,24,800. Budget separately for hosting and annual maintenance.
The main cost drivers are how many systems you connect, your order volume, whether you need Plus-only checkout features, public-app compliance, and how clean your ERP’s API is. Quotes often leave out hosting, third-party API fees and rework after App Store review, so ask about each one.
Questions to ask on a discovery call, and red flags
Questions worth asking
- Can you show a comparable app on a dev store, or a live App Store listing?
- Will you build on the GraphQL Admin API, and how will you handle version upgrades?
- Who owns the code, the Partner account and the hosting after handover?
- What happens when a sync fails overnight, and how fast do you respond?
- Can you split the scope into milestones, each with acceptance criteria?
Red flags
- Only theme portfolios: you may end up paying for their learning curve.
- “We’ll do it in the theme” for logic that needs an app: it breaks when the theme is updated.
- Code on their account with no handover clause: switching agencies later gets expensive.
- No mention of privacy webhooks or billing for a public app: expect rejection in review and a delayed launch.
- A fixed price with no written scope: expect arguments over change requests.
When a Kerala agency is enough, and when to widen the search
A local shortlist is usually enough for custom apps, Functions, and integrations with Razorpay, Shiprocket, Tally, Zoho or an Indian ERP, as long as the agency can show similar work. Widen the search if you’re building a public SaaS app aimed at Built for Shopify status and nobody on your shortlist can show a shipped App Store app.
Next step: how to brief an agency and request a quote
Send the same brief to every agency so the quotes you get back are comparable:
- App type: custom, public, extension, integration or headless.
- Your Shopify plan, since Plus changes what checkout and Functions can do.
- The systems to connect (ERP, CRM, POS, courier, gateway), with API documentation links.
- Must-have and nice-to-have features, listed separately.
- Data volumes: orders per day, SKUs, locations.
- Code ownership and handover expectations.
- Post-launch support, including API version upgrades.
- Budget range (state whether it includes GST) and target launch date.
If you’re also replatforming, read about migrating your store to Shopify. If you’re weighing a plan upgrade, see Shopify Plus development.
Ready to compare quotes? Send this checklist to two or three agencies from the table. If your project involves ERP, POS or custom API work, send your brief to Seamedia and ask for a milestone-based estimate, with the evidence from the eight criteria above.
FAQ
Which Shopify app development agency in Kerala should I shortlist?
Going by their own websites, Intertoons, Globosoft and Ormeon list Kochi addresses, Chainzent lists Trivandrum and Seamedia lists Malappuram. Final Apps could not be confirmed. Shortlist the two or three whose pages show your app type, then check each one’s Partner Directory listing and ask for live examples.
How long does it take to build a custom Shopify app?
As a rough estimate, a small custom app or Shopify Function takes 2-5 weeks. A Tally, Zoho or ERP connector takes 1-4 months. A public App Store MVP takes 3-6 months, including Shopify’s review. Unclear scope and slow API access on the ERP side are the most common causes of delay.
Is my agency ready to build a public Shopify App Store app?
Ask for a live App Store listing they built, and ask how they handled review feedback. They should explain Shopify billing, mandatory privacy webhooks, App Bridge for embedded apps, access scopes and API version upgrades. If they can’t show a shipped public app, budget extra time for review rework.
What is the difference between a private and a public Shopify app?
A custom (private) app serves one store and doesn’t go through App Store review. A public app is listed on the Shopify App Store, must pass review, must bill through Shopify and must handle privacy webhooks. Keeping it compliant is ongoing work as Shopify updates its rules and API versions.
How much does custom Shopify app development cost in India?
As an illustrative estimate at ₹1,500 per hour, a small custom app costs about ₹90,000-₹2,25,000, a Tally or Zoho connector ₹1,80,000-₹4,50,000, and a public app MVP ₹4,50,000-₹12,00,000. Add about 20% for QA and change requests, then 18% GST, plus hosting and maintenance.
Do I need Shopify Plus for a custom app?
No. Custom apps for admin workflows and integrations work on non-Plus plans, as do thank-you and order status page extensions. Customising the information, shipping and payment steps of checkout, and running Functions from a custom app, generally need Plus. Check the current limits in Shopify’s documentation.
