A single sale page for an accounting firm's company registration service, built as the landing page for paid advertising. The design answers an impatient visitor's two questions, what it costs and how long it takes, in the first screens, and keeps the next step beside wherever they stop reading.

01 / Discovery & Heuristic Gaps

Problem & Usability Gaps

A visitor arriving from an advertisement has two questions and little patience: what it costs and how long it takes. Read against the heuristics, a corporate site answers neither where they land; a quoted price that later grows by government fees misleads them; and a single contact form at the end of the page asks them to scroll to the bottom at the moment they decide.

Design Decisions by Heuristic

01
Visibility of system status
Four Steps and a Stated Finish
Registration is shown as four numbered steps, from completing the form to receiving the full set of documents, with the completion time stated beneath them. The visitor sees the whole process and its end point before they commit.
02
Error prevention
The Price, With What It Excludes
Three packages list their inclusions against each, and the note that government registration fees sit outside the quoted price runs directly beneath. The number a visitor sees is one that still holds after the call.
03
Flexibility and efficiency of use
Contact After Every Block
A free-consultation bar with phone and LINE repeats after each section, and the same contact sits in the hero. A single-page funnel converts wherever the reader stops, so the next step is always beside them.
04
Consistency and standards
The Same Order on a Phone
The step flow and the client wall were laid out for mobile as well, so the steps read in the same order and numbering on a phone as on a desktop.

"Ad traffic is expensive and impatient. If the first screens do not show the price and the timeline, the click has already been paid for nothing."

Design Learnings

→

On a paid-traffic page, visibility means the price and the timeline in the first screens; anything placed later asks an impatient visitor to keep reading first.

→

Disclosing what a price excludes is error prevention for the visitor and protects the number's credibility at the same time.

→

Designing the offer block twice forced the third card's job to be decided explicitly, in a way that arguing about it in the abstract would not have.
