Custom Ecommerce Development: Headless or Fully Custom
We build online stores for one brand: yours. Custom ecommerce development at Ronas IT comes in two models, and the right one depends on how your business runs. One model keeps the backend you already have and adds a storefront designed around your brand. The other is built end to end, for when pricing, roles, and operations need more room than an off-the-shelf platform can give. Two models, two budgets.
Two ways we build
The choice comes down to operational complexity, not catalog size. If you run a standard catalog and checkout, a headless storefront — a new custom storefront on top of the backend you already run — is the faster, lighter route. If you need per-customer pricing, user roles, approval flows, or ERP integration, a fully custom platform is the fit.

No SaaS backend underneath — we build the whole platform, and you own it
The headless model puts a fast, custom storefront (built with Next.js) on top of your Shopify or other SaaS backend, through its API, and hosts it on Vercel. Every storefront we ship is designed and built for the brand that owns it.
This service builds single-merchant stores. If you sell on behalf of many vendors, that's a different product; see our custom marketplace development.
What we build
Every store we build covers the operational core of running a shop, not a set of template features. Both models cover that core; the model you need depends on the operational logic on top — per-customer pricing, roles and approvals, or deep ERP, warehouse, and POS integrations point to a fully custom build.
Catalog & search
Product catalog, filtering, and search, with recommendation engines when discovery drives sales.
Cart & checkout
Custom cart and checkout logic: saved carts, multi-step flows, and rules specific to how you sell.
Payments
Stripe and PayPal, buy-now-pay-later (BNPL), and secure card handling, wired into web storefronts and the mobile apps we ship with React Native development.
Inventory & multi-warehouse
Online, warehouse, and in-store stock in one place, with restocks, batches, and availability rules.
Order management
Order summaries, statuses, fulfilment, and returns handled in a single flow.
Custom pricing, roles & approvals
Per-customer price lists, user roles, spending limits, and approval chains for teams that buy in bulk.
ERP, warehouse, POS & CRM integrations
We integrate with any system that exposes an API — ERP, warehouse, POS, and CRM, from NetSuite, SAP, or Odoo to Salesforce or Square — so your store and back office stay in sync on one source of truth.
Recurring orders & subscriptions
Recurring-order logic for products people reorder on a schedule.
Storefronts we design
Every store we build gets a custom storefront designed around your brand, not a theme you tweak. From full product catalogs to single-product pages, these concepts show the kind of ecommerce design our team delivers.
Who it's for
We provide ecommerce website development services for single-brand merchants, and match the model to your operations.
D2C brand
You outgrew a Shopify theme and want a storefront that looks and behaves like your brand, on a headless build.
SMB retailer
Your operations have grown past what a template allows; custom pricing, roles, or warehouse logic point to a fully custom build.
B2B & wholesale
You sell to business buyers and need B2B ecommerce development: per-client price lists, ordering portals, and approvals. Per-customer pricing, roles, or ERP integration means a fully custom build.
Replatforming merchant
You're moving off a platform you've outgrown and want to keep your catalog, customers, and rankings. The next section covers how.
Migration & replatforming
Replatforming isn't a rebuild from zero. Our ecommerce migration services move your catalog, customers, and order history from a Shopify theme, WooCommerce, Magento, or a legacy custom build, and protect the SEO you've already earned.
We map old URLs to new ones with redirects, carry metadata over, and keep structured data intact to protect the rankings you've earned. Before launch we check that catalog, customers, and orders match the old store, run the new one alongside it, and cut over with a rollback plan designed to avoid downtime and data loss. Migration makes sense when you've outgrown a theme, hit a platform's limits, or need checkout logic your current setup can't support.
Our ecommerce development process
Both models follow the same path, from the first call to launch and beyond.
- 1
Discovery call
Free, no commitment
A free discovery call to understand your product, how you sell, and where the current setup limits you. We talk through which of the two models fits and what the store has to do.
- 2
Analysis phase
$2,000–$3,000 · 1–2 weeks
We map your catalog, integrations, and workflows, then write up scope, user stories, flow maps, and architecture. You get a fixed estimate you can act on, so the budget doesn't drift once the build starts.
- 3
Design
Designed around your brand
Interface and flows designed in-house around your catalog and checkout: product pages, cart, and account screens built for how your customers shop.
- 4
Development
From 6 weeks headless · from 3 months custom
We build the model you picked: a headless storefront on top of your SaaS backend, or a fully custom platform on Laravel. Catalog, checkout, payments, and the integrations your operations run on are wired in and tested.
- 5
Launch
Deploy, check, hand over
Deployment, final checks, and full handover. The store goes live and it's yours to run.
Support after launch
Our work doesn't stop at launch. We monitor the store, ship updates, and help it evolve as the business grows, billed hourly at $50/hour.
You own the code, the documentation, and the infrastructure accounts — you are never locked in to us.
Case studies
The ecommerce functionality we designed and built spans catalog, cart, checkout, payments, inventory, and order management. Every line below links to the case behind it.
Eco cosmetics
Full retail flow we designed and built for a beauty marketplace: a catalog of top-rated products, a cart grouped by seller, clear checkout, and order management with color-coded status badges. Payments run on Stripe Connect with BNPL support, and sellers pass KYB onboarding. Delivered in about 16 weeks.
Custom payment solution
A secure custom web checkout with adaptive 3D Secure 2 and PCI DSS compliance, saved carts, device fingerprinting, and fallback payment methods. Built in 10 weeks.
Chef's Crate
An inventory management system with batch and stock management, records of past restocks and deliveries, order-pickup statuses, and reorder flows for packaging. Built in about 6 weeks.
Lainappi
Booking, payment, and owner-verification flow we built for a live rental marketplace, on Stripe Connect. The app recorded 5,685 launches.

Why Ronas IT for custom ecommerce development
We start by telling you which of the two models you actually need — often the lighter, cheaper one — not whichever bills more. You own everything at handover, with no vendor lock-in. And our pricing is on this page, not gated behind a sales call. Design is done in-house next to the developers who ship it, the team that scopes your project stays on it through launch, and our work is rated on Clutch.

Ecommerce development cost is a function of the model you choose. Headless starts lower and ships faster; fully custom scales with the logic you need.
