Services

Everything between the idea and the software that runs in production.

One accountable team for the whole job: Shopify apps and stores, iOS and Android apps, custom software — and the research, automation, AI, commerce and cloud work around them. We are deliberately focused: we do these things properly rather than everything adequately.

What we build

Eight things we are asked for most.

Each has a page of its own: what we build, how long it takes, how it is priced, and the questions we are asked first.

Shopify apps

Shopify app development

House of Marka builds Shopify apps that pass App Store review first time — Remix, Polaris, Shopify Functions, checkout extensions, billing — and ships its own.

Custom Shopify apps

Custom Shopify apps

Custom Shopify apps for one store: ERP and warehouse sync, custom pricing and checkout rules, admin tools and storefront features the App Store does not sell.

Explore

Shopify stores & themes

Shopify store customisation

Customise any Shopify website: theme development, custom sections and templates, Online Store 2.0 migrations, Shopify Plus checkout and B2B. By House of Marka.

Headless Shopify

Hydrogen headless storefronts

Headless Shopify storefronts on Hydrogen and Remix, hosted on Oxygen, or Next.js on the Storefront API — built by House of Marka to be fast, editable and yours.

Speed & page optimisation

Shopify speed optimisation

Shopify speed and page optimisation measured in Core Web Vitals: theme and app audit, image and script fixes, LCP, INP and CLS — with before-and-after numbers.

iOS apps

iOS app development

iOS app development for anyone with an idea: native Swift and SwiftUI, or React Native and Flutter, from wireframe to App Store release. By House of Marka.

Explore

Android apps

Android app development

Android app development for anyone with an idea: native Kotlin and Jetpack Compose, or React Native and Flutter, from idea to Google Play. By House of Marka.

Custom software

Custom software development

Custom software and SaaS by House of Marka: web platforms, internal tools, integrations, automation and applied AI. Fixed-fee discovery, senior team, your code.

Around the build

The wider practices.

Most of our work sits where these overlap — a Shopify app that needs real AI inside it, or a marketplace integration that has to survive a Black Friday.

Research & Consulting

Answers with evidence attached

Extensive research and advisory for US, UK and European teams: market-entry studies, AI readiness, vendor bake-offs, technical due diligence. Every study ends in a ranked backlog with honest costs — from a team willing to build what it recommends.

01

Market-entry and competitor research with unit economics

02

AI readiness audits and EU AI Act compliance sprints

03

Vendor selection and procurement bake-offs

04

Technical due diligence for investments and acquisitions

05

Fixed-fee discovery: architecture, plan, price — yours to keep

Automations

Work that runs while you sleep

Agentic and deterministic automation across operations — document intake, reconciliation, triage, reporting. A two-week ROI audit ranks the opportunities; then we build the top of the list with guardrails and logs a lawyer can read.

01

Automation ROI audits with ranked registers

02

Agentic workflows with human approval gates

03

Document intake, matching and reconciliation

04

Support automation with resolution economics

05

Spend ceilings, kill switches and full audit trails

Applied AI

AI systems that do real work

Agents, retrieval pipelines, evaluation harnesses and human-in-the-loop workflows built on frontier models. Not demos — systems with guardrails, cost ceilings and measurable accuracy.

01

Autonomous agents with tool use and approval gates

02

RAG over private documents, catalogues and support history

03

Model evaluation, red-teaming and regression suites

04

Fine-tuning, distillation and cost-per-task optimisation

05

Voice, vision and multimodal interfaces

Commerce Systems

Merchants connected to every channel

One catalogue, one inventory truth, every marketplace. We build and operate the integration layer that keeps listings, stock, pricing and orders in sync.

01

Marketplace listing, inventory and order sync

02

Shopify, Magento, BigCommerce and headless builds

03

PIM, ERP and 3PL integration

04

Repricing, feed management and channel analytics

05

Cross-border tax, VAT and fulfilment logic

Cloud & Data

Infrastructure that stays quiet

Azure, AWS and GCP. Infrastructure as code, sensible cost controls and the kind of monitoring that pages a human only when it should.

01

Azure-first architecture and migration

02

Terraform, Bicep and CI/CD pipelines

03

Data warehouses, ELT and BI layers

04

SOC 2, GDPR and ISO 27001 readiness

05

24/7 monitoring and incident response

Engagement models

Three ways to work with us.

We will tell you which one your problem needs — including when the answer is a smaller engagement than you asked for.

Discovery sprint

Fixed fee · 2–3 weeks

Architecture, scope, risks and a costed delivery plan. Yours to keep, whoever builds it.

  • Technical & data audit
  • Solution architecture
  • Clickable prototype
  • Costed roadmap
Most common

Build engagement

Fixed price or monthly pod

A senior pod of three to six people, shipping weekly against an agreed scope, with demos you can attend.

  • Design & engineering
  • QA and release management
  • Weekly demo & written report
  • Full IP transfer

Managed operation

Monthly retainer

We run what we built — monitoring, incident response, iteration and marketplace channel management.

  • SLA-backed support
  • 24/7 monitoring
  • Quarterly roadmap
  • Security patching

Delivery

What the first ninety days look like.

01

Scope

A short paid discovery. You leave with an architecture, a plan and a fixed price — whether or not you build it with us.

02

Prototype

Working software in weeks, not slideware. We prove the risky part first, on purpose.

03

Build

A senior pod of three to six people. Weekly demos, a shared board and direct access to the people writing the code.

04

Operate

Launch is the middle, not the end. We monitor, patch, iterate and report against agreed SLAs.
