Dinaya
A multi-tenant SaaS where a Sri Lankan business gets a branded booking page, real payments, automated reminders, and an operations dashboard — the software a salon or clinic needs to run, not just a website.

Dinaya
Booking-and-payments infrastructure for local businesses.
The Problem
A salon, a clinic, a tutor — small service businesses in Sri Lanka run on WhatsApp messages and a paper diary. They lose bookings to no-shows, they can't take a deposit, and a "website" from a typical agency is a brochure that captures nothing.
Dinaya is the opposite bet: the website is the operational tool. It takes the booking, takes the payment, sends the reminder, and hands the owner a dashboard to run the day.
A booking page that can't take money is a poster. The whole product lives in the parts that are hard: payments, tenancy, and reminders that actually fire.
The System
Dinaya is multi-tenant from the ground up. Each business gets a branded public booking page at /book/[slug] and its own {slug}.dinaya.lk subdomain; behind it sits an operations dashboard for calendar, clients, locations, staff, and automations. Payments run through PayHere; the platform bills its own tenants across three subscription tiers.

The Build
The Proof
Beyond the core, Dinaya carries a growth layer — reviews, referrals, a discovery directory, and an AI workflow hub — because the businesses that adopt it need customers as much as they need a calendar. The product ships as a live demo while the studio settles the dinaya.lk apex.
Margin Notes
- What broke first: reminder delivery. "Send a reminder 24h before" is trivial until you handle timezones, cancellations, and reschedules — the reminder has to chase the current state of the booking, not the one that existed when it was scheduled.
- What I'd redo: model deposits vs. full payments as distinct states earlier. Retrofitting partial payment onto a paid/unpaid boolean was avoidable pain.
- What shipped anyway: true per-tenant branding on subdomains. It's the detail that makes a small business feel like the software is theirs, not a rented booth.
