4 decimal places for Sales, Purchases, Inventory

I am trying to use Manager.io to help do the accounts of a money changer operation. As such, I am using currency as stock. These ‘stock’ are purchased by the base currency and then sold.

This is all good but the system does average costing of the ‘stock’ and rounds it up to 2 decimal places when I would love it to be 4 decimal places. This is the same for its sale and purchase, as it becomes critical when calculating profit.

Is there a way to make the entire Manager report in 4 decimal places

No. But you can record inventory item movement to many decimal places. So I don’t see what the issue would be. Your actual purchase and sale transactions will occur in amounts in circulation for your base currency. You just need to distinguish inventory currency from operating cash.
