The website task: serve visitors and listing members.
28card.com presents collectible card listings alongside categories, search, member listing tools and private messaging. Visitors want to find relevant information, while members need to publish content and communicate with other users. Planning this type of website involves defining those different tasks as well as its visual design and copy.
Three connected parts of the platform
01 / Categories and search
Categories help visitors narrow their options; search supports a more specific need. A similar project needs a clear set of card or product data fields before deciding which information should become a category or search criterion.
02 / Member listings
Members contribute listing content, so reading information and publishing it are distinct journeys. Field names, image presentation and instructions all affect how easily that content can be understood.
03 / Private messaging
Messaging allows someone interested in a listing to contact the other party. Information display and communication have defined roles here: payment and fulfilment are arranged directly between buyers and sellers, rather than being presented as a payment process managed by the platform.
Read a feature list alongside the user journey.
A list containing “membership, search and listings” is not enough to define a complete development scope. A similar platform needs step-by-step decisions about who can browse or act, what information they provide, what happens after submission and who handles the content. These are questions to resolve for a new project; page count alone cannot determine the quotation.
| User journey | Questions to resolve for a new platform |
|---|---|
| Find content | What are the main categories? Which information should search cover? |
| Publish content | Who can create listings? What text, images and required fields are needed? |
| Contact someone | Where do users communicate? Which information can be public? |
| Manage daily operations | Who updates content? What administration and maintenance are required? |
Does your business need a full platform?
If you only need to introduce products and receive WhatsApp enquiries, a product showcase may already support your goal. User publishing, account-based data management and more complex searches introduce additional features and ongoing maintenance needs. Defining the essential tasks first helps keep the project focused on the business activities it needs to support.
Membership and listing features require a separate quotation.
The HK$5,000 offer covers a standard business information website with one language and 5 pages. Its delivery period of 3 working days starts once content, assets and design direction are confirmed. The membership, listings, search and private messaging shown on 28card.com are outside this plan. Pricing and delivery for these features depend on the agreed workflows, functionality and maintenance scope.
Start with one real user journey.
For example: “A member uploads a product, then a customer finds it through search and sends an enquiry.” Add the information and administration your business needs, and we can use that journey to discuss a suitable scope and approach.
