Goal-led Workflow
Clear objectives, responsibilities and decision points so the project keeps moving and changes are understood.
Fit
For businesses treating ecommerce as a serious sales channel
A clear commercial reason for the project makes design and development decisions easier. This section helps qualify the fit before either side commits time to a proposal.
A good fit
- UK businesses launching a considered ecommerce store
- Established retailers redesigning or extending an existing Shopify site
- Brands moving from another ecommerce platform to Shopify
- Teams needing theme, app, extension or integration work
- Businesses that want development connected with SEO and paid marketing
- Stores that care about usability, conversion and easier day-to-day management
Probably not yet
- Projects looking only for the cheapest unmodified theme
- Stores without product information, imagery or a decision-maker
- Businesses expecting development alone to guarantee sales or rankings
- Complex migrations that must happen immediately without discovery or testing
- Projects with no agreed commercial goal for the store
Packages
Website packages
Four packages, starting from £300, give you a sensible starting point. Migration, integrations, and catalogue size still need a proper scope before we quote.

Process
A controlled route from store planning to launch
Six steps, one clear route: discovery, structure, theme and UX, development and integration, migration and testing, then launch and support.
Discovery
Understand the products, customers, business model, current platform and required functionality.
Store structure
Plan navigation, collections, product information, content and the main routes to purchase.
Theme and UX
Shape a responsive storefront that reflects the brand and makes products easier to browse and buy.
Development and integration
Configure Shopify, build the required functionality and connect approved third-party systems.
Migration and testing
Move agreed data where required, test the complete buying journey and prepare redirects and launch checks.
Launch and support
Release the store carefully, hand over the agreed setup and plan any maintenance or improvement work.
Need
Common Shopify problems we fix
A store can look great and still be hard to grow. Confusing navigation, slow pages, a clunky checkout, a theme nobody on your team can actually edit. Sound familiar? That's usually where we come in.
The current store is difficult to navigate, especially on mobile.
Products are hard to find, compare or buy without unnecessary steps.
The theme looks generic or no longer reflects the quality of the brand.
Apps and integrations have made the store slow or difficult to manage.
A migration is needed without losing products, customer data or continuity.
The business needs new functionality that the current setup cannot support.
Marketing campaigns need better product, collection or landing pages.
Why OMH
Shopify development is connected to the wider job of selling online
Good ecommerce development thinks beyond the theme. Products, operations, customer trust, marketing and measurement all matter. It's why UK businesses come to a Shopify development agency like ours instead of briefing a single freelancer for the build and hoping the rest sorts itself out.
A goal-led workflow
The store is planned around what customers need to do and what the business needs to manage.
Development and marketing together
Shopify work can be considered alongside SEO, paid advertising, landing pages and reporting.
A practical support route
Maintenance and improvement work can be scoped after launch instead of being mixed into every build.
User-friendly handover
The store should be understandable for the people adding products, processing orders and managing content.
Testing before launch
Responsive layouts, forms and buying journeys are checked before the store is handed over.
Clear commercial scope
Package values stay visible, while migrations, integrations and custom requirements are reviewed separately.

FAQ
Questions before you brief a Shopify project
Support and commercial terms carried over from the current service page are clearly marked where confirmation is still needed.
Shopify expert or development company: which do I need?
A single Shopify expert can be perfect for a quick fix or a small theme tweak. For a full build, a migration, or ongoing growth, a Shopify development company brings planning, development, testing, and marketing support together under one roof, instead of you managing several freelancers yourself.
How many people will support my Shopify project?
A dedicated project contact keeps you updated while the appropriate technical team completes the agreed work.
How do I start a Shopify project with OMH?
Send a project brief through the contact page, email support@onlinemarketinghelp.co.uk or call 020 3489 3934. The first discussion is used to understand the store, goals and practical options.
Can you build a new Shopify store?
Yes. New-store work can cover structure, theme and user experience, Shopify configuration, approved integrations, testing and launch.
Can you migrate my existing ecommerce website to Shopify?
Yes, after the current platform, catalogue, customer data, integrations, URLs and launch risks have been reviewed. Migration work is scoped separately where required.
How much does Shopify development cost?
The published packages on this page start at £300. Recent ecommerce projects give a sense of typical scope. Migrations, integrations, custom apps and other advanced functionality need a confirmed scope before a final proposal is issued.
What happens if the project scope or cost changes?
Any requirement that changes the agreed scope should be explained and approved before extra work begins, so the commercial effect is understood.
Do you provide Shopify support after launch?
Thirty days of complimentary support begins at handover, with extended support available afterwards. Longer support is scoped alongside the project.
Can you support Shopify SEO and marketing?
Yes. We also provide SEO services and paid social advertising, so development can be planned with product discovery, landing pages and campaign tracking in mind.
