Hi there, we have started doing some share trading through my trust. I have worked out how to account for the shares through Inventory however, when we sell the share at a profit, how do I get Manager to exclude the brokerage fee from the profit? Inventory only seems to account for the cost of purchase and sale and then automatically calculates the profit off that?
Any assistance would be greatly appreciated.
Thank you 
Manager uses an average cost for Inventory cost. This may not be appropriate if you are required to use FIFO by your tax authorities.
To include brokerages in the cost you need to post them to the inventory chat of sales account.
This will be similar to freight-in charges. See the guides for handling freight-in charges.
While you can manage investments in Manager, I would advise using a program more adapted to investment management where prices, capital gains and historical data can be administered.
If you mean the profit from between the actual buy and sell of the share prices, then add the brokerage fee as a separate line item when selling.
This will only work when purchasing shares, not when selling shares.
Manager does all that for me.
