Project Details

Shuangxi plays Mahjong Competition Rules (MCR) and wanted one monthly ranking for every player at every table. The app uses the venue's colours: ivory tiles on green felt, lucky red for the primary button, and a title face close to their logo. Every player is recorded by phone number, so their points add up wherever they sit.

The Basic and Premium prices are in the pricing table on this page. The Custom plan is priced after the brief. Cost depends on the number of pages, whether you need a dashboard, and any extra features.

The Basic plan takes 5 business days once we have the deposit and your materials. If you need it sooner, a 1-day express build is available for an extra fee. For custom websites, we give you an estimate at the start based on the scope.

The Basic plan includes responsive design, up to 5 pages, a domain and hosting for the first year, WhatsApp and Google Maps integration, basic SEO, and a warranty. The Premium plan adds up to 10 pages, a blog, and a dashboard to manage your own content.

The domain and hosting are free for the first year. After that, both renew every year. Ask about the cost during your consultation so you can plan for it before ordering.

You do. The domain and the website belong to you, so your business does not depend on us. If you ever change providers, the domain and the site's content go with you.

Payment is in stages: a deposit to start the work, then the final payment once the project is finished as agreed.
