UWAGA! W Polsce HUB jest używany przez dzieci w Szkołach z synchronizacją Dysk Google razem z VPN Free. Hub usunąłem i nigdy do niego nie powrócę bo jest w nim pełno usług dla młodzieży. Wolę Swith vs Switch Key PIN vs linia papilarna.

I've been using Schedule once for about a year now and it has massively improved the professionalism of my coaching company. Before it I used to be back and forwards messing about with clients trying to find times when we were both free. I now just send them a link and they book it for themselves. They really love the fact that they can manage changes and that they get reminders the day before. I really can't imagine how I managed before - highly recommended :)

I started using ScheduleOnce a few months ago and it's been a real time saver. I have a link to my ScheduleOnce profile in my email signature, so when people need to meet with me, it's easy and convenient. They can get it done without me having to do that old back-and-forth matching up schedules. The only thing I wish I could do is more easy schedule meetings with multiple ScheduleOnce customers. I have a group of 4 people who all use this tool, but we still have to do some manual work to get a mutually agreeable time. It's a nitpick on an otherwise useful tool. Obviously we all 4 are using it!

Very useful I am the sales director of an eCommerce web design agency and I have been using Scheduleonce for a few months now. I can say is that it has greatly improved efficiency in scheduling numerous online meetings with potential and existing clients. It is easy to use on my end, easy to understand for our clients and synchronizes with my Google Apps Calendar. What else can you ask for? I have recommended Scheduleonce to my co-workers, which have quickly adopted the solution. It is an affordable solution to the complex problem of matching people’s agendas. Thanks Scheduleonce for improving our efficiency.

I hate the back and forth of scheduling appointments. Now that I discovered schedule once... I don't need to hold spots and wait for someone to get back in touch with me. This has freed up time, energy, and frustration. I can't wait to launch this across my entire small business. This is the most useful app I have found in a long time! Thanks!

I run a small service company, I'm constantly on the road or on a site, and don't have an office staff to take calls or schedule appointments. I've had my service techs build their MeetMe link into their email signature so that clients can see what's available and choose what works best for them. So far, it's saved us quite a bit of time; I think we'll keep it!

As a busy consultant, and small business owner, I constantly find myself behind the scheduling 8-ball as I juggle to find time on my calendar for meetings with current clients, business partners and prospects. Scheduling one meeting at time -- to avoid a log jam of availability issues -- is the worst solution in the world, and punting my calendar to our project manager just shifts a ridiculous amount of work to another area of our business. When I found ScheduleOnce, blocked out six weeks of available meeting time and sent a personal email (with a link) to 50 clients and prospects in 30 minutes, it was like a weight off my back. Even better? More than 40 of them found and booked time on my calendar within three days.

With the seamless integration into Google Calendars, ScheduleOnce is by far the best appointment and meeting scheduler out there. I have researched a lot of different options but none have as simple and clean interface as ScheduleOnce. It has made our lives so much easier and our customers much happier. We spend less time worrying if we missed or overbooked people because we can simply check our Google calendar and see who is scheduled and at what time and all of their contact info in right in the calendar. We have been able to integrate it in our Web site with no one knowing the difference. I would definitely recommend to others.

I've searched the web for an Online Scheduling system that is intuitive and works in a way that makes it easy for my clients, and colleagues to use without having to know coding and technical jargon. Unlike many other digital products and services, ScheduleOnce is a tool - not a toy. It can really increase the quality of your leads. Get paid before you waste time rescheduling people or dealing with flaky people who may cancel last minute. It integrates with Google Apps for Business and Education. The way the world of the web is changing, you need to be able to manage your calendar, schedule, availability without being distracted with all of these "tools, apps, widgets" out there. ScheduleOnce is that and more... it's what I like to call a "game changer" - Love it, highly recommend it!

Before I'd have to do a lot of back & forth with clients to schedule time. That not only wastes time it makes me come off less professional. ScheduleOnce solves this!!!!!
