Headless and composable commerce
Headless storefronts, composable commerce and custom platforms for brands whose pricing, bundling and fulfilment rules need their own architecture. We start with an assessment.

01The approach
Custom eCommerce development suits brands whose selling model has outgrown a template.
What changes for you
Think per-account contract rates. Think a build-your-own-box flow held together by four apps.
We build composable, not monolithic. The commerce engine, ERP and payment links that work stay where they are. We replace the one layer causing the pain. Your pricing rules become real objects with tests.
Across 150+ projects and 10+ years of team experience, every custom build we ship ends up maintained in-house. A headless storefront takes fourteen to twenty weeks.
What this buys you
02Services
The assessment decides which one fits your selling rules, before anyone writes code.
| Most chosenHeadless storefront A React or Next.js front end. It sits over the commerce engine you already run. | Composable commerce Cart, search, CMS, payments and pricing chosen one by one. Built around what earns your money. | Custom commerce engine A back end written from scratch. For a selling model nothing off the shelf can hold. | |

A React or Next.js front end. It sits over the commerce engine you already run.
Cart, search, CMS, payments and pricing chosen one by one. Built around what earns your money.
A back end written from scratch. For a selling model nothing off the shelf can hold.
03Process
The first stage settles the architecture, so the other four never have to guess.
We map your rules first. Your actual business rules written down, then checked one by one against what your current platform can express. The gap decides the architecture.
Services chosen before a line of code. Commerce engine, search, CMS and payment services selected and contracted, with your pricing and bundling logic modelled explicitly. The migration path out is documented while it is still easy.
Storefront and logic in parallel. The front end goes up alongside the custom services, with performance budgets enforced in CI rather than checked at the end. You get a deployed preview on every pull request.
Cut over quietly. Catalogue and customer migration, the full 301 map from the old structure, and analytics verified against live traffic. Your team chooses the window.
Your engineers take the codebase over. Your engineers are onboarded onto the codebase with a recorded walkthrough and paired sessions. A retainer is there afterwards if you want one.
Stage 02 · Architect
04Included
Your business rules written down. Then checked against what your platform can express.
The engine, ERP and payment links that work stay put. We replace the one layer that does not.
Bundles, plans, contract pricing and fulfilment rules as real objects. Each one has its own tests.
Edge rendering and a component layer you control. No template engine eats your speed.
Plain frameworks, standard patterns, real tests and docs. Any good team can pick it up.
You could return to a platform later without a rewrite. Keeping the option open is the point.
05Results
Live client stores, each measured against a number that was agreed before the work started.
Sales
A smart batting tee and coaching app for baseball and softball hitters, from youth players to pros. The brief was Japanese retro-cyberpunk, all neon, scanlines and chromatic edges, on a store that still opens instantly on a phone.
+35% Order value
Conversion
Swing-mechanics and vision trainers built by players for players: strobe glasses, reaction lights, swing locks. A deliberately minimal storefront that puts the product demonstration first and gets out of its way.
+56% Organic traffic
Conversion, from 1.5%
Bamboo swaddles, sleep bags and everyday babywear for Indian parents, much of it bought for infants with eczema. Hundreds of products, tens of thousands of orders and years of ranking history moved off a slow WooCommerce build without losing any of it.
+30% Organic traffic
Organic traffic
Farm-to-market kratom and kava from a family-owned Southeast Asian farm, sold to a US audience that reads labels closely. Six years of SEO equity, hundreds of products and thousands of pages moved off WooCommerce with every ranking intact.
+45% Conversion
Direct revenue
Stress balls, journals and planners for people managing their own mental load. An established Amazon seller that wanted a direct channel of its own: catalogue ported across, multi-market listings configured, conversion designed for.
No.1 Channel, ahead of Amazon
Sales
Handwoven jamdani turned into contemporary womenswear by a Kolkata label that refuses to greenwash. The store already existed; what it lacked was a path from admiring the craft to buying it.

09FAQ
The questions we are asked most often about custom eCommerce development.
Still unsure?
Ask us anything before committing to a call. Most questions get a real answer within a few hours.
hello@syscodes.inYou need it when your pricing or bundling cannot be expressed on a platform. Or when several apps patch one gap, or the theme layer caps your speed. The assessment checks your rules and answers it in writing.
Headless commerce development splits the storefront from the engine behind it. You can rebuild one without touching the other. It earns its keep when the template layer caps speed. It also helps when one catalogue feeds several channels.
A headless storefront over your existing engine runs fourteen to twenty weeks. Composable commerce runs eighteen to twenty-eight. A full custom eCommerce platform development project runs twenty-four to thirty-six weeks. Unique selling rules drive the range.
Hosting, monitoring and a steady share of engineering time each year. We size that with you at the planning stage. It is planned, not discovered. Every custom build we ship ends up maintained in-house.
Yes, and we design for it. Keep the commerce engine intact and replace only the front end. The exit stays open, and it is written into the plan.
