Welcome to the Community @Jaileer! Thanks for bringing this up. Unfortunately, there is no way to change the decimal settings at this time. A possible solution is to invoice the total amount due rather than per item and select "Customize" to add a note for the item count.

The note will show up in the Invoice below the item name for your records as well as the customer's

Hope that helps! Don't hesitate to let us know if you have any further questions.
