The best B2B eCommerce agencies in the UK (2025 guide)

For UK-based manufacturers, distributors and wholesalers, growing revenue and modernising operations has never been more important, or more difficult. 

Sales cycles are longer. Tech stacks are messier. Customer expectations are higher. And while B2C gets the spotlight, the reality is that B2B buyers expect just as much from your digital experience.

That’s where the right B2B eCommerce agency makes the difference.

A good agency will build what you ask for. A great one will challenge your brief, improve your plan, and help you connect the dots between your systems, your strategy and your customer experience. 

But finding that kind of partner isn’t easy.

With hundreds of agencies now offering eCommerce services, and most of them built around B2C or templated builds, it’s hard to know who actually understands the real world of B2B.

This shortlist cuts through the noise.

We’ve profiled five UK-based agencies that understand the operational reality of B2B commerce. They’ve delivered proven results for manufacturers, wholesalers and distributors. They know how to work with ERPs, trade accounts, custom pricing, global sales channels and all the back-office chaos that makes B2B different.

If you’re planning your next move in digital commerce, start here. These are the UK’s best B2B eCommerce agencies for 2025.

1. Rixxo

Platform focus: Platform-agnostic
Based in: Bristol

Rixxo is a strategic partner for B2B businesses navigating digital transformation. Unlike traditional eCommerce agencies that focus solely on design and development, Rixxo specialises in platform selection, integration strategy, and implementation planning, making them a trusted advisor for mid-market and enterprise firms looking to scale.

Rixxo helps manufacturers, wholesalers and distributors choose the right tools, connect the right systems and build the infrastructure for long-term growth. Their independent, platform-agnostic approach means decisions are based on fit, not sales targets or preferred vendors.

Rixxo works best with ambitious B2B businesses that have outgrown their current systems or are heading into a significant change (like replatforming or systems consolidation). Their team embeds into the business, asking the hard questions, mapping out constraints, and aligning operations, technology and commercial strategy.

Platform focus: Magento (Adobe Commerce), Shopify, WooCommerce
Based in: Kent

chilliapple is a UK eCommerce consultancy and development agency that blends strategic insight with hands-on execution. They’ve carved out a niche helping businesses — especially those undergoing digital change — gain clarity before committing to major platform or technology investments.

Where many agencies jump straight into design and build, chilliapple starts with the “why” behind the project. Their consultancy services include in-depth audits of current systems, identification of bottlenecks, and structured technology roadmaps. This approach is particularly valuable for B2B businesses navigating internal complexity, legacy platforms or out-of-sync tech stacks.

• Site migrations and replatforming projects
  
• Conversion rate optimisation and performance tuning

• Consultancy-first approach with real commercial insight
  
• Multi-platform capability, ideal for clients evaluating options
  
• Transparent pricing and delivery models
  
• In-house team of UK-based consultants and offshore developers, offering flexibility on project scope and budget
