Service website design for a business that sells time, not products

Selling a service is harder than selling a product in one specific way

The customer cannot see what they are buying before they pay. A shirt you can judge from a photograph; a consulting engagement you cannot. The whole job of a service website is to close that gap.

Three things close it:

State the scope plainly. Not "we provide comprehensive solutions" but "we do A, B and C; we do not do D". Specificity builds trust faster than any adjective.

Publish a price, or a range. A page with no price makes visitors assume expensive and leave. If you cannot commit to a fixed figure, give a floor or a band — "from 8 million", "typically 20–50 million depending on scale". You lose the enquiries that cannot afford you, which are the ones you want to lose.

Show the work. Before and after photos, numbers, client names where permitted. One concrete project page is worth ten paragraphs of self-description.

One page per service, always

This is the biggest difference between a service website that gets customers from Google and one that only exists so you can send a link to people you already know.

If you do five things, you need five pages. Each with its own title, its own content, its own price and its own questions. A single "Our Services" page listing five bullets ranks for none of them, because it says nothing deep enough about any one.

The site you are reading is built on exactly that principle.

The route to contact has to be short

Somebody who needs a service usually needs it soon. A tappable phone number on mobile, a Zalo button that opens the conversation directly, and a short form for people who prefer to write. The enquiry reaches your Zalo within seconds, carrying the page they were reading when they sent it — because which page produced the question changes how you answer it.
