Reservation & Service Businesses
Knovik builds custom booking systems for businesses that take reservations against limited capacity: real-time availability that never double-books, local payment gateway integration, and automatic invoicing into the accounting software you already run.
Why This Industry
Whether the bookable thing is a hot desk, a salon chair, a clinic appointment slot, or a recording studio, the underlying problem is the same: capacity, payments, and accounting all have to agree with each other in real time. We built exactly this for Cowork.lk — six bookable space types with overlap-aware availability (a half-day booking correctly blocks the relevant half of a full-day slot), PayHere payment collection with signature-verified webhooks, automatic Zoho Books invoicing, a returning-member loyalty discount, and a front-desk dashboard for walk-ins — all verified against a real running instance before shipping.
What We Build
For reservation & service businesses teams
Real-Time Availability Engines
Availability modeled as live capacity, not a shared calendar: overlap-aware slot blocking, per-resource inventory counts, and rules like half-day/full-day interactions handled in the engine so double-booking is structurally impossible.
Payments & Invoicing Sync
Local payment gateway integration (like Sri Lanka's PayHere) where bookings are only confirmed on a cryptographically verified webhook, with invoices created automatically in the accounting system the business already uses.
Front-Desk & Member Tooling
Staff dashboards for live availability, walk-in bookings, and phone payments, plus member accounts with loyalty pricing — the operational layer that makes the booking engine usable by the people at the counter, not just the website.
