Wix and Squarespace are good tools. The question isn't whether they can build a nice site — it's whether you should be the one operating them. For most small-business owners, the honest answer is no.
The DIY trade-off
With a builder you get full control and a low sticker price. You also get the job: choosing a template, fighting the layout on mobile, writing the copy, sizing the images, and keeping it all updated. It's not hard, exactly — it's just hours you don't have, repeated forever.
The done-for-you trade-off
With a service like Lumo, you describe your business once and approve the result. We design it, write it, register the domain, and host it. You trade a little control for getting those hours back — and for a result built by someone who does this every day.
Pick DIY if building the site is the fun part. Pick done-for-you if running your business is.
There's no universally right answer — but if your time is worth more than the saving, done-for-you usually wins.
