Shopify Development Guide: What Can Be Built and How

Description

Guide Shopify development: what can be built, and how

Almost anything a merchant wants from Shopify is done at one of four layers: settings, the theme, an app, or an integration with another system. Knowing which layer a requirement belongs to tells you what it will cost and who can do it. This guide explains the layers and links to every Shopify service, integration and guide WavX publishes.

Discuss a Shopify requirement Last updated 2 October 2026

The four layers of a Shopify store

Layer

What it controls

Who does it

Typical requirement

Settings

Products, prices, taxes, shipping rules, payment methods, staff

The merchant

"Add cash on delivery", "Charge shipping by weight"

Theme

How every page looks and what it shows

The merchant, within the theme's options; a developer beyond them

"A size chart on product pages", "A different layout for one collection"

Apps

New behaviour: subscriptions, bundles, reviews, loyalty, custom pricing rules

Installed from the App Store, or built for one store

"Bundle discounts", "Delivery-date picker", "A rule the store does not have"

Integrations

Data moving between Shopify and other systems

A developer, or a ready-made connector

"Orders into Tally", "Stock from the warehouse system", "Shipments to the courier"

Start at the top. A requirement that settings can meet does not need a theme change, and one that a theme change can meet does not need an app. Each step down costs more and adds something to maintain.

How to tell which layer you need

It is about what the store sells or charges. Settings.

It is about what a page shows or how it is arranged. Theme. See theme development .

It is a rule or a process the store does not have. An app. Check the App Store first; if nothing fits, see custom feature development and custom app development .

It involves another system. An integration. See Shopify integrations .

It is the checkout. What can be changed depends on your Shopify plan. See checkout customisation .

What to decide before any custom work

What an existing app would cost over two years, against owning the feature.

Who maintains it. Shopify releases new API versions on a schedule, so custom code needs someone to keep it current.

Whether the store's speed can absorb it. Every app and script adds weight; see speed optimisation .

Whether Shopify is still the right platform for where the business is going. The comparisons below cover that honestly, including the cases where it is not.

Shopify services

Custom Shopify apps When your store needs an app the Shopify App Store does not have: what a custom app is, what each plan allows, and how WavX scopes and builds one.

Shopify integrations Connecting Shopify to Tally, Zoho, Shiprocket, Razorpay and other systems: when the vendor's own connector is enough and when a custom integration is needed.

Shopify speed optimisation Why a Shopify store is slow and what fixes it: apps, theme code, images and third-party scripts, measured with real-user Core Web Vitals before and after.

Shopify migration Moving a store to Shopify from WooCommerce or another platform: what data moves, what does not, how URLs are redirected, and the checklist WavX follows.

Custom Shopify features Bundles, custom pricing, delivery-date pickers, COD rules: which Shopify features need a theme change, an app, a Function or an API integration.

Shopify SEO Shopify generates canonical tags, a sitemap and robots.txt, and fixes its URL structure. What that leaves to fix, and the SEO work WavX does on a Shopify store.

Shopify theme development What a custom Shopify theme involves: Online Store 2.0 sections and blocks, what a theme can and cannot change, how WavX builds one, and when not to.

Conversion optimisation Where Indian Shopify stores lose orders (COD and returns to origin, payment steps, checkout fields) and what each Shopify plan lets you change. No uplift promised.

Checkout customisation What can be changed in Shopify checkout on Basic, Grow, Advanced and Plus as of October 2026, which tools do it, and what WavX builds.

Maintenance and support What changes under a Shopify store after launch, what a monthly maintenance plan covers, how requests are handled and how it is priced. No fixed SLA is published.

Subscriptions and recurring orders How subscriptions work on Shopify, why its own recurring billing does not reach UPI Autopay in India, and what WavX configures or builds instead.

B2B and wholesale What Shopify's built-in B2B features cover on each plan, where an Indian wholesale business outgrows them, and when a custom dealer portal is the better buy.

Frequently asked questions

Do I need a developer for my Shopify store?

Not for most of it. Products, collections, payments, shipping rules and a standard theme are set up from the admin without code. A developer is needed when the store must look or behave in a way the theme's settings do not offer, when no existing app does what you need, or when Shopify has to exchange data with another system.

Should I build a custom app or install one from the App Store?

Install one if it does the job at a price that makes sense over two years. Build one when no app fits your process, when you would need three apps stitched together to get one feature, or when the monthly fees add up to more than owning the feature.

Can WavX work on a store someone else built?

Yes. We start by reading the theme code and the installed apps, because most problems on an inherited store come from the two interacting.
