ECOMMERCE THAT LOADS FAST AND CONVERTS FASTER

Most ecommerce sites are bloated, slow and built on platforms that fight you at every turn. Thinksay builds online shops that load in under a second, score 95+ on Google PageSpeed, and are designed from the ground up to turn browsers into buyers. And because we're a full-service agency, we shoot the product photography too.

Why your online shop needs to be fast

Every second of load time costs you roughly 7% of conversions. On a site turning over £10,000 a month, a 3-second delay is costing you £700 every month in lost sales. Most Shopify and WooCommerce sites take 4–8 seconds to load on mobile.

Our ecommerce sites load in under 1 second. That's not a marginal improvement — it's a fundamentally different technology that Google rewards with higher rankings and your customers reward with their wallets.

Why choose a full-service agency

Most ecommerce businesses use one agency for the website, another for photography, and another for marketing. The result: product photos that don't fit the design, marketing that doesn't match the brand, and three invoices where one would do.

With Thinksay, one person builds your shop, photographs your products, and markets them. The images are shot specifically for the layouts, the marketing matches the brand, and you deal with one human who knows your business inside out.

Questions about ecommerce

What platform do you build on?
We build custom ecommerce rather than using off-the-shelf platforms like Shopify or WooCommerce. This means faster sites, no monthly platform fees, and complete control over your design and functionality. For businesses that specifically need Shopify or WooCommerce, we can work with those too.
Can you migrate my existing online shop?
Yes — we regularly migrate ecommerce sites from Shopify, WooCommerce and other platforms. We handle the product data migration, URL redirects, and design rebuild.
Do you do product photography?
Yes — in-house. Nick photographs your products as part of the ecommerce project, so the images are shot specifically for the layouts and optimised for web. No separate photographer needed.
What about payments and shipping?
We integrate with Stripe, PayPal, and other payment providers, and set up shipping calculations based on your requirements — flat rate, weight-based, or carrier-calculated.
