Building BigCommerce stores for shoppers and AI-driven buying journeys

01 / Discovery

Make product data easier to understand

We structure product information so shoppers and AI-driven discovery experiences can interpret products, variants, attributes and availability accurately.

02 / Conversion

Assist the buying decision

We can add AI-assisted discovery, comparison and recommendation experiences around your existing catalogue. The goal is practical: help customers narrow large product ranges.

03 / Personalisation

Respond to buying context

Personalisation can use customer context, catalogue relationships and shopping behaviour to change what buyers see and how products are presented.

04 / Operations

Reduce repetitive commerce work

We identify catalogue, merchandising, order and support tasks where AI can reduce manual handling without taking control away from your team. That can mean better internal search, content assistance.

Where could AI improve your BigCommerce store?

Send us your current store and the buying or operational problem you want to improve. We will identify where AI adds practical value and where it does not.

BigCommerce capabilities

What we build and improve on BigCommerce

Custom storefront development

  • We build storefront experiences around your brand, catalogue structure and customer journeys rather than forcing your requirements into a generic design.

  • We translate approved designs into production storefronts with responsive behaviour, interactive elements and reusable components for ongoing management.

Headless commerce development

  • We build decoupled storefronts when you need more control over customer experience, frontend performance or how commerce appears across digital channels.

  • We connect the customer-facing application to BigCommerce while keeping catalogue, order and commerce operations working behind the storefront.

BigCommerce store setup

  • We configure catalogues, product variants, categories and search behaviour around the way your customers need to find and buy products.

  • We prepare stores for regional commerce requirements including currencies, languages and location-specific business rules where your operation requires them.

Third-party integrations

  • We connect BigCommerce with inventory, warehouse and business-management systems so product, order and operational information can move between your systems.

  • We integrate marketing and customer systems where your team needs ecommerce activity to trigger communications, segmentation or other business workflows.

Custom app development

  • We build private applications that automate internal workflows, manage commerce data or introduce functionality specific to the way your store operates.

  • We develop applications intended for use across multiple stores when your product needs to serve a broader ecommerce merchant audience.

BigCommerce migration

  • We migrate ecommerce stores to BigCommerce while retaining important product information, customer records, catalogue structures and other critical commerce data.

  • We use migration as an opportunity to improve storefront layouts and customer experience without unnecessarily changing the parts already working well.

BigCommerce work

BigCommerce projects built
around real requirements.

BigCommerce · Automotive

A faster headless automotive storefront

We developed a headless BigCommerce approach for an automotive performance business, separating the customer-facing experience from commerce operations. The resulting architecture gave the client greater control over storefront performance while retaining BigCommerce for the underlying ecommerce requirements.

BigCommerce · Retail

Storefront redesign for growing retail

We transformed The Knife Connection storefront on BigCommerce to support a stronger customer experience as the business expanded online. The work focused on presenting products more effectively, improving storefront usability and creating a better foundation for engagement and conversion.

BigCommerce · Specialty retail

A clearer speciality retail experience

We redesigned the Bonsai Outlet storefront to give shoppers a clearer and more engaging way to browse its specialist product range. The BigCommerce work focused on the customer-facing experience, helping the business create a stronger foundation for engagement and conversion.

BigCommerce · Payments

Gift card integration for merchants

We integrated Smart Transaction Systems gift card functionality with BigCommerce stores, giving participating merchants a way to support gift card transactions inside their ecommerce operation. The work connected merchant account requirements with the storefront purchasing experience.

Client feedback

What our clients say

After launch

Your BigCommerce store keeps changing.

A commerce build does not stop changing when it goes live.
New products arrive, catalogue structures expand, business systems change, campaigns need landing pages and customers expose edge cases that were difficult to reproduce before launch.

We stay involved after delivery to maintain and improve the store.
Our engineers can handle frontend changes, landing pages, integrations, operational updates, search improvements and defect fixes. You get continuity from a team that understands the build rather than having to explain the architecture again whenever the next requirement appears.

Store changes

We implement ongoing storefront and content changes as your catalogue, campaigns and customer requirements develop.

Integration upkeep

We maintain connections as your surrounding business systems and the data moving between them change.

Search support

We can implement ongoing on-page search improvements alongside technical changes to the ecommerce storefront.

Engineering support

We investigate defects, make production changes and support new requirements after your BigCommerce store goes live.

BigCommerce development questions, answered

We build security into the development and operational process rather than treating it as a final launch task. Our work includes secure coding practices, regular security reviews, controlled access and planned backups and recovery procedures.

For integrations and custom applications, we also consider what information needs to move between systems, which users need access and how permissions should be separated. The exact controls depend on your store architecture, integrations and internal requirements. We can review those requirements during project discovery and include the relevant security work in the implementation plan.
