Square will only let you charge a price up to two decimal places, so you can't do it directly. However, you can get four-decimal precision by adjusting the unit definitions and pricing strategies.

Define a Smaller Unit of Measure:
- Instead of pricing per standard unit (e.g., per gram), define a smaller unit that aligns with your desired pricing precision.
- For example, if you wish to price an item at $0.0250 per gram (which isn't directly possible due to the two-decimal limitation), you can redefine the unit to milligrams. Since 1 gram = 1,000 milligrams, the price per milligram would be $0.000025.
Set Up the Custom Unit in Square:
- Navigate to your Square Dashboard:
  - Go to Items & Orders > Items > Units.
- Click on Add a Unit.
- Define the unit (e.g., milligram) and set the precision to the necessary decimal places.
- Save the new unit.
Apply the Custom Unit to Your Items:
- In your item library, assign the newly created unit (e.g., milligram) to the relevant items.
- Set the price per this new unit (e.g., $0.000025 per milligram).
Ring Up Sales Using the Custom Unit:
- When processing a sale, enter the quantity in terms of the new unit. For instance, if a customer purchases 2 grams, you'd enter 2,000 milligrams.

This should effectively get you where you need to be (danged ole metric system)

What exactly are you trying to do the fractional pricing? I only ever see that at gas stations nowadays.

Thanks Donnie. I am selling solar credits, so it is energy related. It is priced in &/kilowatt hours or $/kwh. I actually had already tried the customer unit method but when creating a new item with the new unit, I'll be danged....2 decimals. 😞
