It's a good app overall. I had some issues with it being slow, and with the language part. But the customer service team is amazing and got in touch with me right away to fix the language issue. Now it's all resolved. Thanks so much.

Hi Dianne,
We apologize for the problems. We migrated to the cloud and some accounts need to reset their password so they get properly migrated. If you could please provide your email and send it over to support@billingsapp.io we will get it fixed and give you a 1 year premium for free for the troubles.
Thanks for your understanding,
Adrian
