Why should you choose Power Diary?


Affordable Pricing For Practices of All Sizes

With affordability being such a big factor when choosing the best practice management system for your practice, it’s no surprise that pricing is top of our comparison.

It’s easy to see how costs can quickly add up with TM3, with the cost of 7 calendars reaching over twice that of Power Diary, and over three times the amount for 15 calendars. And that’s not all; unlike Power Diary, many of our most popular features such as online appointment booking, treatment note templates and electronic invoicing will come at an additional cost with TM3, quickly making it very expensive.

See our detailed cost breakdown below.


Auto-Appointment Processing & Confirmation

Automated SMS and email appointment reminders have been proven to drastically reduce the number of no-shows a practice will experience, and although both TM3 and Power Diary have this functionality, only Power Diary is able to process client responses and update the appointment status accordingly.

Auto-processing is not only convenient for the client, but for the practitioner involved too, freeing up their valuable time to focus on running their practice, not to mention saving on administration costs.


Seamless Two-Way Communication Within the App

As well as auto-appointment confirmation, Power Diary has advanced two-way SMS communication functionality. Whilst TM3 allows SMS and email communication via their app, the messages sent are one-way only, with email responses arriving in your inbox rather than remaining within the app. This often causes communication to become disjointed.

Need to remind a client to bring paperwork to their appointment? No problem! Power Diary facilitates two-way communication with clients, keeping everything together in the app for ease. You are also able to use this with colleagues, as well as other healthcare providers, so sending information and client reports has never been simpler.

In addition, you can send bulk emails and SMS messages, ideal for marketing, sending promotional offers and newsletters, notifying clients of holiday hours, and much more.


A Fully Brandable Client Portal to Impress Clients

Client portals can be extremely effective when looking to streamline your practice, often enabling clients to book, amend and cancel appointments, as well as pay for them, view invoices, share documents, and more.

With client portals becoming more popular, and often being the main port of call for clients both existing and new, it makes sense for your portal to be recognisable with your branding.

Although with TM3 you are able to add your logo and choose from various colour schemes, Power Diary provides a stand-out client portal experience, giving you the ability to fully customise your portal to suit your specific clinic, to really impress your clients. You can add your logo and a header image, brand colours, personalised appointment instructions, your cancellation policy and more. No more generic colour schemes.

No risk with our Money-Back Guarantee

Yes, you read that right! Simply start your account now and if at anytime over the next 12 months you think Power Diary isn’t right for you just cancel your account and we’ll refund 100% of any subscription fees you’ve paid.
