Build a store that scales

BigCommerce provides teams with a flexible, stable foundation, but like any CMS, maximizing its potential depends on the quality of the build. We help brands design and develop BigCommerce sites that remain fast, convert reliably, and integrate smoothly with the systems running your business. 

From new builds and replatforming to B2B trade sites and complex API integrations, our teams focus on what matters in commerce: a better customer experience, a simpler operational model, and a platform you can evolve as your business grows. 

Builds and Replatforming

End-to-end delivery for new BigCommerce sites or migrations, including discovery, UX, build, data, integrations, and launch planning to minimize trading risk.

Maintenance and Support

Ongoing improvements to speed, UX, and conversion, plus practical support for releases, incidents, and enhancements so your platform continues delivering post-launch.

Built for Trading, Not Just Launch

We treat BigCommerce delivery as a business product. That means clear priorities, measurable outcomes, and a release plan that safeguards trading. We focus on details that keep revenue flowing.

Senior Specialists, Embedded with Your Team

You get direct access to experienced eCommerce strategists, designers, and engineers. We work alongside internal stakeholders, platform partners, and third parties, keeping decision-making fast and communication clear from discovery through BAU.

Built for Scalable, High-Performing Commerce

BigCommerce is an excellent choice for brands wanting SaaS speed and security without losing flexibility. We turn that capability into a site that looks great, performs under pressure, reflects your brand, and supports daily trading. 

As a BigCommerce Elite Partner, IDHL is known for sites built around real customer journeys, with clean, high-performing front ends and a backend set up for efficient merchandising and content updates.

The result is a platform that converts, scales with demand, and is practical for teams to run and evolve.

A Delivery Partner You Can Rely On

Our delivery approach reduces risk and builds momentum from day one. We start with structured discovery to confirm requirements, integrations, and trading priorities, then proceed to UX and technical design to avoid surprises during build. 

Development follows a clear sprint cadence with regular demos and early integration testing built in. As launch nears, we support UAT, cutover planning, and training. We remain involved post-go-live, helping eCommerce, IT, and operations teams strategize and prioritize improvements with measurable trading impact.

"With BigCommerce, success comes from knowing where to customize and where it’s best to keep it simple. BigCommerce provides the flexibility, and our technical experts help guide that balance so our clients move faster, spend smarter, and scale with confidence."
