A good theme is the fastest route to a credible site, and we sell them ourselves. But the decision should not come down to price alone.
Pick a theme when
Your content fits a common shape — a few service pages, a blog, a contact form — and you need to be live soon.
Go custom when
Your business logic is unusual, the site has to talk to systems you already run, or the brand itself is the product and a recognisable template undermines it.
The middle path
Launch on a theme now, keep the content structure clean, and rebuild on custom in a year once you know which pages actually earn their place.
