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.

FAQ

Online booking builds: common questions.

Should I use Calendly, Square, or a custom booking system?

If a standard scheduler already fits your services, staff, and pricing, use it, and we will embed it cleanly. Custom booking earns its cost when you have rules an off-the-shelf tool cannot express: multiple resources per appointment, deposits that vary by service, room or table logic, or a workflow that has to hand off into other software.

Can bookings sync with the calendar we already use?

Yes. Two-way sync with Google Calendar and Microsoft 365 is standard, and many practice, salon, and restaurant systems expose an API we can write to, so a booking made on your site shows up where your team already looks.

Does a custom booking system take payments?

It can. Deposits, full prepayment, or a card on file for no-show fees all run through Stripe or the processor you already use, and refunds and cancellations follow the policy you set rather than a generic default.
