Composable commerce architecture
A diagram of your services, the data each one owns, and the APIs and events that connect them.
The Problem
When One Platform Decides What Your Store Can Do Next
You feel the limits after a few good years on one platform, when search, content, or trade pricing needs more than its apps can give.
01 · Content
Landing pages wait weeks for a developer to build them.
A headless CMS lets your marketing team publish pages without code changes.
02 · Search
Shoppers can't search by the attributes your products really have.
A dedicated search service indexes every attribute your catalog carries.
03 · Trade pricing
Trade buyers need price lists the platform charges extra for.
Price lists and company accounts come from a service built for trade rules.
04 · Big rebuild
Replacing the whole platform puts every order and URL at risk.
We move one capability per phase, so the store keeps selling throughout.
Your marketing team wants a new landing page, and it waits weeks for a developer. Shoppers search by material or fit, but the results page can't read those attributes. Trade buyers need their own price lists, and the platform's add-on costs more than the work behind it. Every fix arrives as another app, and each one loads into the same theme. Replacing the whole platform means a long project with every order at risk. So the backlog grows, and the platform sets the pace.
We start with a capability map: what your commerce engine, CMS, search, PIM, OMS, and payments each do today, and what each one costs to run. Then we move one capability at a time to its own service, connected by APIs and webhooks, while your current store keeps taking orders. Content goes to a headless CMS your team edits. Search moves to a service that reads your attributes. You change the parts that hold you back, not the whole platform.
Capabilities mapped before code
Each part of your stack gets a keep, buy, or build call with its running cost.
One phase at a time
Content, search, or pricing moves first, while the current store keeps selling.
Every account in your name
Vendor contracts, API keys, and repositories stay with your company, not with us.
Our Composable Commerce Development Process
From Stack Review to Composable Store in Five Clear Steps
You see the capability map and running costs before any build, then approve each phase on staging while your store keeps taking orders.
We look at your platform, apps, contracts, and the systems each order passes through. You get a short answer on composable commerce vs headless for your size, and whether either is worth it yet.
What's Included
What You Get From Our Composable Commerce Agency
Each engagement covers what your stack needs now: the plan, the services, the connections between them, and a new storefront when you're ready.

DeveloperLook vs Big-Bang Rebuild vs All-in-One Suite
An all-in-one suite suits many brands, and a full rebuild is sometimes the fastest route. Here's where each holds up and where it strains.
| Feature | DeveloperLookBest fit | Big-bang rebuild | All-in-one suite |
|---|---|---|---|
| Planning | Capability map with running costs | One large spec up front | You pick a plan tier |
| Scope of change | One capability per phase | Everything changes at once | Limited to apps and settings |
| Tool choice | Best fit per capability | Best fit per capability | The suite's own tools |
| Launch risk | Small, tested cutovers | One large cutover | Low, since little changes |
| Testing | Staging with real catalog data | Mostly at the end | Vendor-tested features |
| Running costs | Several vendor bills, shown first | Several vendor bills | One subscription, least overhead |
| Ownership | Your accounts, code, and data | Yours if handed over | Data yours, platform theirs |
| Cost | Fixed price per phase | Large upfront budget | Lowest upfront cost |

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built online stores, platforms, and integrations for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Growing Brands Trust Us With Composable Builds
The team running your composable program should make your stack easier to change, not harder to run. These habits keep each phase predictable.
Honest about running costs
A composable stack means several vendor bills instead of one. We show those costs beside the build price, and if one platform still fits you, we'll tell you before we quote.
One phase, then the next
Each phase moves one capability and ships before the next starts. Your team learns the new setup step by step, not all at once.
Tools picked by your needs
We recommend vendors by your catalog, markets, and team size, and explain each trade-off in writing. You see why every tool made the list.
Failures that announce themselves
Each webhook and sync writes a log and sends an alert when a record fails. Your team hears about a stuck order before a customer does.
Notes for every service
Each service comes with notes on the data it owns, the events it sends, and how to restart it. Any developer you hire can pick up the stack later.
Contracts in your name
Vendor accounts, API keys, and repositories are opened under your company. You can switch agencies or bring the work in-house without asking us.

Good fit
Brands outgrowing an all-in-one platform
Your store runs well, but search, content, and pricing rules now need more than your platform's apps can give without workarounds.
B2B and hybrid sellers
You sell to trade accounts and consumers, and you're weighing composable commerce for B2B price lists, quotes, and company accounts.
Teams facing a platform renewal
Your platform contract renews soon, and you want a composable commerce migration plan before you sign another long term.
CTOs choosing an implementation partner
You're comparing composable commerce companies and want one that shows running costs and a phased plan, not just a demo.
Agencies with composable clients
Your agency won a composable project and needs engineers for the integrations and the storefront, delivered under your brand.
Not a fit
Budget under $1,100
Your budget is under $1,100, or your catalog fits easily within one platform's features. Our Shopify Development Services team can build that store instead.
Only a new storefront
You only want a faster custom storefront on your current back end. Our Headless Commerce Agency page covers that narrower build.
Same features, new platform
You're moving to another platform with the same features you have now. Our Ecommerce Replatforming Services team handles that move with less overhead.
No one to own vendors
Nobody on your team can own several vendors and their contracts. A composable stack needs that owner, so an all-in-one platform is the safer choice.

Send a message or book a call with the team.
Each business capability runs as its own service, and APIs connect them. Your storefront asks the commerce engine for prices and carts, the CMS for content, and the search service for results. Webhooks keep orders, stock, and product data moving between services, so you can change one part without rebuilding the rest.
It lets you replace the part that holds you back without replatforming everything. You can move search or content to a better tool, keep your checkout, and skip a risky full rebuild. The trade-off is more vendors to manage, so it pays off mainly for complex catalogs, several markets, or trade pricing.
A blueprint with DeveloperLook starts at $1,100, a first build phase at $3,800, and a composable storefront at $8,200. Vendor fees for the engine, CMS, and search are billed to you directly and often exceed one platform plan. You get a fixed quote for each phase after a free stack review.
Expect a 2 to 3 week blueprint, then build phases of 6 to 16 weeks each. Content or search usually moves first, because it carries the least checkout risk, and a new storefront takes longest. Your store keeps selling between phases, so there's no single risky launch day.
It's a commerce engine built to run headless and expose its features through APIs, such as commercetools, Elastic Path, or BigCommerce with its Catalyst storefront. Shopify also lets enterprise brands use only the parts they need. No single composable commerce solution fits every brand, so we compare engines by your catalog, markets, and running costs.
MACH originally stood for Microservices, API-first, Cloud-native SaaS, and Headless, the principles the MACH Alliance set out in 2020. The alliance now describes its standard as open, composable, and connected. You don't need every principle on day one: many stacks start with an API-first engine and add services later.
Your headless CMS stores pages, stories, and banners, while the commerce engine keeps products, prices, and carts. The storefront pulls from both through APIs and merges them on each page. Your editors reference products inside CMS entries, so landing pages show live prices and stock without copied product data.
Headless separates only the storefront, and the back end often stays one platform. Composable goes further and splits the back end into services, such as search, PIM, and payments, that you can replace one at a time. Headless is often your first step, and most composable stacks include a headless storefront.
No, AI shopping agents don't require a composable stack. They need accurate product data, live prices and stock, and a checkout they can reach. Single-platform stores already offer that through feeds and protocols such as the Universal Commerce Protocol from Google and Shopify. Composable helps when agents must read data spread across your systems.
You own all of it: repositories, vendor accounts, API keys, and hosting sit under your company's name from day one. We document each service and the events it sends, so another team can maintain your stack. Every plan includes 30 to 60 days of support, and later phases are quoted as fixed-price work.
