For set decimal places please follow below steps.

•  Moon invoice Pro -> Company -> Edit -> Decimal places -> Here you can change decimal point.

For example, decimal value is $45.44786. Now, if you set 2 for Decimal Places, it will show decimal amount like $45.45
- Here, you can set max 3 points for decimal value.
- This change will apply to values of whole application for that company like due amount, tax amount, total amount, etc.
