Custom apps · Online booking
Online booking system development.
Every missed call is a booking that went somewhere else. Online booking lets a customer choose a service and a time on your website in under a minute, at midnight if that is when they are free, and it keeps your calendar honest without a receptionist in the loop. We build custom booking flows when off-the-shelf schedulers cannot express your rules, working remotely from our Providence, RI studio.
Quick answer
An online booking system lets customers see real availability and reserve a time from your website, with deposits, reminders, and calendar sync handled automatically. GEO Marketing Group builds custom booking flows starting around $8,000, typically $12,000, working remotely from Providence, RI.
What it does
Online booking, in plain language.
An online booking system lets customers pick a service, see real availability, and reserve a time or a table from your website without a phone call. It confirms by email or text, sends reminders, and updates the calendar your team already lives in. We build it custom when off-the-shelf schedulers cannot handle your rules.

How we build it
The stack behind online booking builds.
We usually build custom booking on a Node back end with a Postgres database for availability and reservations, a lightweight Astro front end embedded in your site, Stripe for deposits, Twilio or a comparable provider for SMS, and calendar sync through the Google and Microsoft APIs.
