Shopify Development in Horsham
Horsham is a prosperous market town with a strong professional and financial-services base and a thriving independent retail scene. The work we do is the part most agencies do not touch: the custom functionality, the back-office integrations, and the platform migrations that make a store actually run a growing business.
Trusted by:

Plenty of agencies. A different kind of help.
Horsham is a prosperous West Sussex market town with a strong professional and financial-services base, the kind of place that once headquartered RSA, alongside a healthy independent retail scene. That mix of established businesses and independent retailers means there is no shortage of Shopify agencies happy to take on a storefront. Many are genuinely good at design and brand, and if a smart-looking store is all you need, you are well served locally. We are honest about that. It is not where we add the most.
Where we earn our place is the harder, less visible work that a brand hits once it starts to scale. Connecting Shopify to an ERP or warehouse system so stock and orders stay accurate without manual reconciliation. Building the custom functionality a theme or app cannot deliver. Migrating off an outgrown platform cleanly, without losing SEO equity or trading days.
We are Shopify Select Partners and we have done this for high-volume fashion and lifestyle brands, the same demands a growing Horsham retailer or trade business runs into as it outgrows an off-the-shelf setup.
What most Shopify agencies focus on
- Theme selection and customisation
- App configuration and stacking
- Storefront design and brand alignment
- Monthly retainers for content and updates
Where we spend our time
- ERP and warehouse integrations that actually work
- Custom code for functionality no app handles
- Platform migrations preserving SEO and data
- The technical layer your design agency needs to hand off
Shopify work for Horsham and West Sussex brands
ERP and back-office integration
Connecting Shopify to NetSuite, Peoplevox, Sage, or your warehouse management system so orders and stock flow without manual reconciliation. Real-time sync rather than daily batch updates that are already out of date when they run.
Custom functionality
The bespoke features themes and apps cannot handle: complex product configurators, wholesale and trade portals, account-based pricing tiers, custom subscription flows, loyalty programmes, and checkout behaviour specific to your business.
Platform migrations
Moving from Magento, Visualsoft, WooCommerce, or a legacy platform to Shopify. Product catalogue, customer accounts, order history, SEO redirect mapping, and existing integrations all handled carefully. Trading continuity kept throughout.
Working alongside your design agency
Horsham brands often have a design or creative agency they already trust. We work alongside them: they own the look and brand, we own the technical layer underneath. No territory disputes, no miscommunication, just a clean handoff at the boundary.
ShopFlow: inventory and order management
Our own Shopify integration for brands that need ERP-level inventory and order control without the cost and complexity of a full ERP. Real-time stock, multi-location management, purchase orders, and order routing built specifically for Shopify.
Shopify Plus
Custom checkout extensions, automation workflows, B2B portals, multi-store setups, and the advanced integrations the Plus tier enables. We will give you an honest view on whether Plus is warranted for your revenue level rather than recommending it by default.
Fashion, lifestyle and high-volume retail. The brands that put the integration work under pressure.
Our Shopify work includes custom builds, ERP integrations, and platform migrations for fashion and lifestyle brands that needed something beyond what a theme and an app stack could deliver.
- AX Paris — custom Shopify build with ShopFlow ERP integration, full brand implementation
- Chi Chi London — Shopify development, custom theme and operational integration
- Motel Rocks — Shopify plus Oracle NetSuite integration, complex order and inventory sync
- Cerriga Limited — custom Shopify build with bespoke booking plugin and six-month warranty
- Empire Airsoft — multi-store Shopify migration with ShopFlow ERP and operational integration

Questions worth asking any Shopify agency
The questions we think you should ask any Shopify partner, including us. The honest answers are on our Shopify development page.
- Why would we pay for bespoke development when apps can do most things?
- What happens if Shopify changes something that breaks our custom build?
- We had a bad experience with a previous Shopify agency. How is this different?
- There are much bigger Shopify agencies out there. Why use a smaller one?
- How do we know Shopify is the right platform for us?
- What does Shopify Select Partner status actually mean for us in practice?
- We already have a Shopify store. Can you take it over rather than rebuild from scratch?
- How do we connect Shopify to our existing back-office systems?
- What happens after the store launches?
Questions from Horsham Shopify brands
Yes, and we do this regularly. We handle the technical and integration layer while your design partner owns the look, brand and frontend. Horsham and the wider West Sussex area have plenty of capable design and creative studios. Our work sits underneath: the ERP connections, custom functionality and back-office integrations that make the store actually run a growing business.
Yes. Real-time stock, order and fulfilment integration between Shopify and systems like NetSuite, Peoplevox, Sage, and custom warehouse platforms is core work for us. We have also built ShopFlow, our own inventory and order management system for brands that need ERP-level control without the full ERP cost and complexity.
Done properly, no. A migration handled carelessly loses SEO rankings and trading days. Done properly, it preserves both. We migrate product catalogue, customer data, order history, and SEO redirect mapping carefully. We have structured processes for Visualsoft, Magento, and WooCommerce migrations specifically, and we stage the go-live to protect your trading.
The common requests: complex product configurators, wholesale and trade portals, account-based pricing, custom subscription flows, loyalty and gifting programmes, bespoke checkout behaviour, and features that no app handles cleanly. If your requirement is more specific than a theme or app can manage, that is where we come in.
Not necessarily. Shopify Plus makes sense at meaningful monthly revenue volumes where the additional features justify the higher platform fee. We will give you an honest view on whether Plus is warranted for your specific situation rather than recommending it by default because it earns us more.
Yes, Shopify Select Partners. Select status reflects a track record of building and launching stores to a standard Shopify recognises. We have been doing this since long before Shopify became the default choice for growing brands.
A Shopify store is easy to launch and hard to get right at scale. The work that matters is the part customers never see — how cleanly it talks to your stock, your orders and your back office. That's where we spend our time, writing code rather than stacking up apps.
