No matter what kind of business you own, you will most certainly need an online booking system to keep your customer booking appointments on time.
Having a booking system can assist you in managing your business more efficiently and provide you with a steady stream of income. Here, I have compiled a list of the best online booking systems that you can use for free or at a reasonable cost.
AppointmentCore

AppointmentCore is a cloud scheduling software designed to leverage your Infusionsoft and Google Calendar for online bookings. It also integrates with key cloud meeting apps, such as GoToMeeting and ConferenceCalling.
The app lets you create time slots, where your clients choose their date. It also automatically creates the meeting in Infusionsoft or GoToMeeting. Invitations from both platforms are then sent to clients without manual entry.
Likewise, the app lets you set the lead time for last-minute bookings. Open dates are displayed with at least 48 hours prior notice. You can also set buffer time to help you prepare for a meeting.
Also, we like how the app gives you the flexibility to rotate your team’s availability. Pricing starts at $27 per month featuring unlimited booking links and appointments.

Doodle
Price: Free (Basic), $6.95 one user/month (Starter), $44.75 for 5 users/month (Team), contact for enterprise pricing.
Create meeting polls to send to clients and prospects, suggest meeting dates and times, and allow voting on dates that work all with Doodle’s free version. While the free version might be helpful enough for most individuals, you’ll need to upgrade to the premium pricing tier to remove ads from your polls, set a deadline for the poll, and collect contact information from meeting guests.
The paid version of Doodle’s scheduling software helps you find a time to meet that works for all attendees. The meeting host suggests meeting times, invites participants to indicate their availability, then the meeting host picks a final time. When the time is finalized, a calendar event is added to the host and meeting invitees’ calendars. Plus, there’s a dashboard feature where you can manage all the meetings you have.
