In the quantity part of forms, i.e. purchase orders, how can I alter decimal places to show an additional decimal place so for example it shows 1.510 and not 1.51?

A warm welcome to the Community, Kristina83.

I’m here to share some information about the decimal setting in QuickBooks Online.

The default setting for decimal places in QBO is 2 places after the period. However, you have the option of how the amounts are displayed in your account.

Here's how:

1. Go to the Gear icon and select Account and Settings.
2. Select Advanced.
3. Click anywhere inside Other preferences.
4. Choose your preferred Number format on the drop-down box.
5. Hit Save, then Done.
