What Is an Online Booking System?

An online booking system is a cloud-based software that allows your clients to book appointments on your website or through a booking link. Your staff can also schedule meetings for less tech-savvy patients.

Appointment scheduling apps make booking meetings straightforward because customers immediately see the available hours to select from. Booking apps eliminate the need for spreadsheets, and manual client booking, and redirect clients to pay on another website since they are integrated with payment processors.

When you implement a booking software, your business is open at all times. This leads to revenue growth as 42% of online bookings happen outside business hours.

How Does an Online Booking System Work?

An online booking system is cloud-based. It integrates with your website and social pages.

What happens is this: A client or prospect lands on your website and fills out an embedded booking form to schedule an appointment. 

They input their contact details and select the time and date from available calendar slots. Your client can choose what type of service the meeting is for and immediately pay any consultation fee, all without leaving your website. 

Booked meetings are automatically added to your calendar. Depending on how it’s set up, you will receive a notification or an email.

The booking system takes care of sending emails and notification reminders to both you and your client so that no one misses the appointment.

On your end, you can see the number of meetings booked, notifications, to whom you have to send invoices, and staff activity. You can also book an appointment for a client.

Features of an Ideal Clinic Appointment Booking System

Certain features make a booking app ideal for therapists and clinicians. They are:

  • Extensive Integrations
  • Client and Staff Management
  • Highly Customizable
  • Calendar Management
  • Online Payment Management
  • Customized Activity Dashboards
  • Auto Emails and Reminders

Extensive Integrations

The ideal clinic appointment system integrates with many apps and platforms. On a very basic level, it features a customizable and personal booking link that you can share on social pages and embed in a website.

Apart from integrating with web pages, the appointment scheduling software has an API that supports third-party apps. Recommended integrations include Google Calendar, MailChimp for email marketing, Facebook Login and Pixel, and PayPal.

Client and Staff Management

An online booking system supports multiple clients and staff management.

You usually have a database of client profiles containing contact details, recurring appointments, and patient records. Advanced online booking systems feature client portals. That is, each client has an account they log into, from where they book appointments and view their records.

As an admin, you invite multiple employees as users to your clinic’s account and set their roles and access levels.

Highly Customizable

You should be able to customize booking forms to fit your brand’s voice and image. The booking software should allow changing a form’s style, placing your logo, and adding data fields.

A worthwhile booking app provides you with customizable templates of booking and intake forms, emails, and invoices. Templates help for writing copy that appeals to your particular audience while retaining a particular structure.

Calendar Management

The ideal appointment scheduling SaaS software manages your calendar appointments and keeps you duly notified.

It allows you and your clients to easily add appointments. It supports recurring appointments to your calendar and allows you to set your workdays and business hours. Also, the app shows patients what time blocks are available so they easily match their availability with yours.

Appointment booking apps generate reports about your appointments. You get an overview of when you’re most busy and when your clients most prefer to see you.

The best online booking apps integrate with third-party calendar apps like Calendly, Outlook, and Google Calendar.

Online Payment Management

Most people prefer to pay online because it is effortless, fast, and easily reversible. To attract new clients and reduce churn rates, your booking app should have a built-in payment management system.

Also, the app should not redirect clients to a new web page to pay. People prefer all-in-one solutions that manage payments and automatically notify you when a deposit has been made. This is especially helpful when clients have to deposit a fee before booking an appointment.

An online booking app should allow you to introduce discount policies that reduce prices for long-term special clients and therefore build strong relationships with your patients.

A booking app should have automated invoicing. You should be able to generate a customized invoice for your client. They should also be able to click on a link inside the invoice and pay your fees.

To achieve all these, the software integrate with credit card processors and wallets like PayPal and Stripe.

Customized Activity Dashboards

Especially for an account with multiple users, an online booking software should support an easy overview of recent activities.

Dashboards are important. They offer you an overview of recent activities and an easy way to navigate the software. As the admin, you get to view what new changes were made and who made them.

There should be a general dashboard customized for different levels of access permissions for office staff. This improves patient data security and user experience for employees. 

Auto Emails and Reminders

The best systems keeps you up-to-date with all client activity in the software. 

You get a notification when a patient books an appointment, a payment is made, and an appointment is coming up. You should be able to customize the frequency of notifications and where they are sent. The app should also send email and SMS reminders to your patients.

How To Choose The Best Online Appointment Booking System for Your Business

Are you ready to select an appointment scheduling software for your clinic? Here’s the step-by-step guide to choosing one that fits your business.

1. Identify the main reason why you need a booking system

The first step to choosing the right appointment scheduling app is identifying the main reason why you want to implement one. 

If your biggest issue is messy schedules that are difficult to keep up with, you may need an app with extensive appointment scheduling options. If your customers find it difficult to pay, select apps that lean more on billing. Identifying the main problem is the most important step.

2. Make a shortlist of options

The next step is to make a shortlist of online booking systems that you think are right for your clinic. Your list can only comprise apps that specifically cater to your needs. Here are the top 4 factors to consider while making the list.

a. Security and Compliance

As a business catering to customers with sensitive needs, you need software that securely transfers data and protects your clients’ privacy. You don’t want something easily hacked into or that indiscriminately sells patients’ data. Therefore, look for booking apps that are:

  • HIPAA compliant
  • GDPR compliant

b. Features Available

Before adding an online booking app to your shortlist, get an overview of available features. How does the app book appointments? Does it work with a payment processor? Research the features to confirm that they cover your most important needs. 

In case you’re wondering what features are important, we wrote a blog post detailing the latest trends in online booking. Use them to determine what features should be part of your booking system.

c. Integration

Select only apps that give accounts shareable links and that embed in websites.

The apps should allow third-party integrations and data migration so that you can integrate with other apps for added functionalities.

d. Platform

Cloud-based software is best because your clients won’t need to install applications to book an appointment. All they need is a booking form link.

3. Find reviews on popular sites

When you have a shortlist ready, look at ratings and reviews. Right after this, we have a list of 5 top online booking software for health practitioners. We review their major features, pros, and pricing.

4. Consider an app with a free trial option

We recommend implementing an online booking software little by little. It is better to go for an app that has a free version or a free trial. You can then try the app for some days or in a limited capacity to get a view of what it’ll be like implementing the software fully.
