When selling an investment, on the sales invoice/ receipt
- Create a line for each investment lot being sold showing the purchase price and how many of that lot being sold on this occasion. Allocate it to the balance sheet investment at cost account.
- After listing all lots being sold, allocate the remainder to the Profit and loss “Investment realised gain/loss” account
- keep track of how much of each lot has been sold in an external spreadsheet.
- Tracking investment at cost is currently best done in Manager by ensuring no market valuation prices are entered because Manager currently can not be set up to separate realised and unrealised gain/loss. Entering Market revaluations in Manager can then be done via a journal entry between appropriate Balance sheet and Profit/loss unrealised gain accounts
