Phyathai Hospital

Phyathai is a group, not a single hospital, and the site had to work as one product across all six branches while each of them keeps its own packages, its own pricing and its own availability

Every item carries the branch it belongs to, so a patient browsing from one location never reaches a checkout for something that branch cannot actually deliver

One codebase, one design system, six sets of content. The alternative was six sites that look alike on launch day and have drifted apart within a year

The hard part of this project was never the checkout. It was that the checkout had to agree with the systems the hospital's sales operation already runs on

Packages, pricing and order state move between the website and Phyathai's internal sales system, so a package bought online is a package the branch already knows about, priced the way the branch prices it

No second source of truth. The site does not keep a private idea of what is for sale, which is the failure mode that turns a hospital e-commerce build into a reconciliation problem six months after launch

Booking runs from the package itself: choose a date and time, fill in patient details, pay. Thai payment reality rather than a generic checkout, so credit card and instalments, PromptPay QR, WeChat, Alipay and UnionPay

Hospital marketing does not run on a single discount field. Campaigns overlap, expire, differ by branch, and bundle a main package with add-ons that have their own rules

So that complexity lives in the back office, not in the code. The marketing team configures a campaign; they do not raise a ticket and wait for a deployment

Add-on packages, validity windows, per-branch pricing and bundling rules are all editable, which is what lets the group run a seasonal campaign across six hospitals without touching the site

We continue to maintain the platform, shipping changes as branches, packages and campaigns change through the year

Security and privacy are standing work rather than a launch checklist. This is a system that takes payments and holds patient details across six hospitals
