Pretty much everything else.
1. Their CC processing fees are very tricky and hidden... I am paying an average of 3.3% per transaction. I have interviewed 3 other companies who charge a flat 2.5% or less
2. The very basic reports I need like a list of how many sessions each client has left are not included in my basic level... they want me to pay MORE just to access simple data.
3. The price has gone up $25 per year for nothing that actually helps my business. They just keep calling me to try to upsell me to the next level.
4. It breaks ALL the time. For the past 10 days my staff has been unable to cancel appointment on the mobile app and it has been a nightmare keeping everyone's schedule in order. When I called or tried to chat help it was 45-60 minute wait time to talk to anyone. I would get an email saying these things take time and to be patient... when I asked for a credit for the month because the main thing I need it for does not work, they told me its a normal software problem so sorry no credit.
5. Other than this bit mistake, the software will randomly crash or mess
----- I think they have grown too fast pushing more users and not being able to keep up with their actual product they offer. Save yourself the trouble and by far the highest expense software out there. IT IS NOT WORTH IT
