Pros

The ability to control your calendar is second to none, add that to some great integrations like with Zoom and it is really a great productivity tool. Easily add a widget to any webpage.
I love how easy it is for me to be able to send a link to clients for them to schedule an appointment to speak with me. It's very customizable, and connects seamlessly with Google calendar.
I love this product -- one of the handful I am so happy to pay for. It saves me so much time scheduling meetings, and I love the customization and automation.

Pros

I like the simplicity of the multifactor authentication process. It was easy to deploy on our phones and works perfectly each day.
The app is very easy to use and allows you different options on how you would like to dual authenticate your login. The speed and reliability of this app are great as well.
We needed a good solution to increase our security for signing onto our server, and Duo is great for that.

Cons

Disappointed with this and strongly recommend against going down this road. The Outlook integration is broken, the patch does not work.
Honestly cant think of much to dislike. The only thing that comes to mind is that sometimes the app that is supposed to sync my outlook calendar with my Calendly will crash for no reason.
I got a little confused at one point when people were unable to schedule time with me because the time for the appointment was too close to the time of scheduling.

Cons

They have acknowledged that this is their mistake and they need to fix it, but they seem incapable of doing so.
The downside is that it gets really annoying after a while. All the texts, confirmations, multiple logins, etc. get overwhelming when you just want to check something really quick.
The only real downside to Duo is that each employee has to install it on their personal smartphone, and some people don't like that.

Reviewed 2 years ago

great, super easy to use and helpful for all scheduling efforts

Cross scheduling

Reviewed 7 months ago

It’s not the best it’s not the worst I would definitely go with a security first but it’s a decent platform to use

Pros

I like that Callumley has all of your calendar set up in one area but also Cross checks your Google calendar

Cons

I just want an easier to use scheduling platform where you can kind of spoof up your page somebody can click on a certain time and pay with ease it just seems a little bit more difficult than like acuity

Calendly a preferable tool for scheduling events, meetings and appointments

Reviewed 6 months ago

It made the life easy for managing the scheduling. They have top notch security, lightning fast system and reliable IT systems. I liked working on Calendly.

Pros

Possible to schedule meetings professionally with ease without emails so that staff involvement is minimal or eliminated. It has collaboration functionality and administrative control options. Integration platform is well designed.

Cons

Appointment follow up actions and artificial intelligence based suggestions are some suggested feature i would love to be added to it.

Calendly Helps Streamline Workflows

Reviewed 5 months ago

Overall Calendly has been helpful in streamlining the scheduling process and has allowed us to ensure meetings take place in a timely manner.

Pros

Eliminating the back and forth headache of trying to find dates and times that work for everyone by allowing clients and employees to schedule themselves for meetings has been a huge help in our business

Cons

Does not integrate with our company calendar/email but this is a security feature so I understand why they cant be synced. Definitely not the software's fault.

Calendly

Great tool with limitations

Reviewed 4 years ago

I was able to schedule more calls and in a more efficient way than working through a couple of admins. Not that an admins job is not valuable, but scheduling became simplified by removing a couple of follow up emails.

Pros

I love the functionality of being able to become completely transparent from a scheduling perspective with clients, partners and leads. It takes the place of having to use an admin to schedule with back and forth emails that takes 2 to 3 emails per attempt at scheduling.

Cons

Biggest con, it is an outside link. If you are working with clients who have great security tools, your email might not make it through their spam blocker.

Integrate Calendly into your workflow to make scheduling a breeze

Reviewed 8 months ago
Pros

The simplicity of Calendly and integration with Outlook made it easy to setup and configure to work within our existing workflow and calendars.

Cons

One issue we had was more to do with our mail/calendar security due to Calendly having access to edit the calendar in Outlook. but this was a known issue and resolved easily.

Calendly

A lifesave for scheduling client meetings but can be finicky

Reviewed a year ago
Pros

This is so useful - it allows your clients/customers to pick their meeting times based on your up-to-date calendar availability. Calendly saves me a lot of time when it comes to calendar juggling.

Cons

The connection seems to break frequently with my Outlook - it could be an error on my end though. If you are in an organization with heavy security protocols, you probably may not be able to use Calendly because of the permissions required.
