Ecommerce Questions

Straight answers to the questions we hear most often.

Which ecommerce platform should we use?

It depends on your catalogue, your integrations and how much control you need. Shopify, Magento and WooCommerce each suit different businesses, and a bespoke build makes sense when the buying journey is your competitive edge. We recommend a platform during discovery, based on your needs rather than our preferences.

When is a bespoke ecommerce platform worth it?

When an off-the-shelf store or booking engine is limiting your conversion, flexibility or control. easyHotel replaced an embedded booking engine with a bespoke platform we built. Its conversion rate more than doubled and the site paid for itself within three months of launch.

Can you connect our store to our existing systems?

Yes. We regularly integrate online stores with payment providers, CRMs, ERPs, inventory and product information systems. For easyHotel we unified three payment providers and five property management systems into a single checkout.

Can you work with our branding or design agency?

Yes. We specialise in working with branding and design agencies to realise their vision online, with no compromises. Or we can design the store ourselves.

Do you support stores after launch?

Yes. We maintain, protect and keep improving the stores we build. Our partnership with easyHotel ran for six years, refining key journeys and adding functionality as the business evolved.

Where are you based?

We’re based at 6 Oxford Street in Woodstock, Oxfordshire, and work with organisations across Oxford, Oxfordshire and London.
