Product / Web application

An online booking system tailored to your services, schedules and payments

An online booking system is a web application where customers choose an open time slot, service, or specialist themselves, while the business manages schedules and bookings from one dashboard. It works well for clinics, salons, accommodation, rentals, and service firms where booking by phone or email eats up staff time. DNAVI designs booking systems with online payments and notifications and connects them to an existing website.

A booking system should take work off your team and shorten the customer's path to an appointment. The essentials are simple forms, clear statuses, availability, payments and notifications.

Process

The application should follow your real workflow, not a list of random features.

MVP

A first version delivers business value sooner and reduces project risk.

Data and roles

A sound architecture for data, permissions and statuses makes future development easier.

Integrations

A web system should reduce manual work through APIs, automation and reporting.
