Can the free trial version of Boxin outpatient management system be used?

You can't use it. Boxin software has many traps. When your data exceeds 500, you can't use it, and then you will be asked to pay. That is, after you pay the money, you are asked for money when you upgrade. If you don't pay, you can't use it normally. At first, the free version told you that there were no functional restrictions, but that was false. I've been cheated before.
