Speed and search are your revenue levers

In e-commerce, a second of load time and a page of search ranking translate directly into revenue. We build storefronts with optimised Core Web Vitals, clean product and category URLs, and rich Product and Review structured data so listings earn strong search visibility.

Connected to how your business actually runs

Stores break down when stock, pricing, and orders live in different systems. We integrate your e-commerce platform with ERP, inventory, accounting, shipping, and payment providers so stock and orders stay accurate without anyone re-keying data.

Platform or custom β€” chosen for your model

Shopify and similar platforms are excellent for standard retail. Complex B2B pricing, multi-vendor marketplaces, or unusual fulfilment usually need a custom build. We advise honestly, because forcing a complex model onto the wrong platform is expensive later.

How much does e-commerce development cost?

E-commerce cost depends on catalogue size, custom logic, and integrations. Typical ranges:

Project typeTypical costTimeline
Standard store on Shopify/platform$5,000 – $18,0003 – 8 weeks
Custom-designed store with integrations$18,000 – $50,0002 – 4 months
B2B commerce portal$35,000 – $100,0003 – 6 months
Multi-vendor marketplace$45,000 – $150,0004 – 8 months
Replatforming / migrationFrom $10,0006 – 14 weeks

Ranges exclude platform subscriptions, payment-gateway fees, and third-party app licences, which are billed directly by those providers.

Flexible engagement & pricing models

Every business is different, so we offer several ways to work together. Start with a free consultation and we will recommend the model that best fits your scope, timeline, and budget.

πŸ“

Fixed-scope project

Best for well-defined builds. We agree scope, timeline, and a fixed price up front so you know exactly what you get and what it costs.

πŸ‘₯

Dedicated team

A cross-functional squad β€” engineers, designers, QA, and a project lead β€” that works as an extension of your business, month to month.

πŸ”§

Staff augmentation

Add senior developers or AI specialists to your existing team to fill skill gaps and accelerate delivery without long hiring cycles.

πŸ”

Support & retainer

Ongoing maintenance, optimisation, and new-feature development on a predictable monthly retainer after launch.

Our delivery process

1

Discovery & strategy

We map your goals, users, and workflows, then define scope, architecture, and a clear roadmap with fixed milestones and transparent pricing β€” no surprises, no scope creep.

2

UX design & prototype

Wireframes and interactive prototypes validate the experience and de-risk the build before a line of production code is written, saving you time and budget.

3

Agile development & QA

We build in two-week sprints with continuous integration, automated testing, and live demos, so you see working software early and steer it as it grows.

4

Launch, support & scale

We deploy to the cloud with monitoring, security hardening, and CI/CD, then iterate with analytics-driven improvements and ongoing support as you scale.

Frequently asked questions

Should I use Shopify or a custom e-commerce platform?

Shopify is excellent for standard retail and gets you live fast. Custom builds make sense for complex B2B pricing, multi-vendor marketplaces, or unusual fulfilment logic. We advise based on your model, not a preferred platform.

Can you integrate my store with ERP and inventory systems?

Yes. We integrate ERP, inventory, accounting, and shipping carriers so stock levels, pricing, and orders stay synchronised automatically.

Can you build a B2B store with customer-specific pricing?

Yes. We build account-based pricing, quote workflows, credit terms, approval flows, and bulk ordering for wholesale and trade customers.

Will my product pages rank on Google?

We build with Product and Review structured data, clean category and product URLs, and optimised Core Web Vitals so your listings are technically positioned to rank and show rich results.

Can you migrate my existing store without losing rankings?

Yes. We handle replatforming with careful URL mapping and redirects so search equity and traffic carry across to the new store.

How much does an online store cost?

A standard platform store typically runs $5,000–$18,000, custom stores $18,000–$50,000, and marketplaces more. We quote fixed scope after a free consultation.
