How do I mark the sale of a manual asset?

If the asset value is manually tracked

Step 1: Enter the sale value as the current value of the asset. This will show the updated IRR.

Step 2: Archive the row. Make sure the sale amount is reflecting in your bank account balance on the same day you archive the asset row.

Summary

The asset you owned till now, is now gone from your portfolio, and the money you sold it for is now reflected in your bank account or cash balance.

Don't worry, even if a row is archived, its history will continue to reflect in your net worth. So you won't mess up your Net Worth chart.

If you sold all units of a stock (say you hold 100 AAPL and sold all 100)

Just archive the asset row (click on the 3-dots) > Archive > confirm.

If you sold a portion of a stock (say you hold 100 AAPL and sold 50)

Go to the stock details screen (click on the 4-line icon on the right side of the asset row) and update the Quantity to 50.

This will show the updated value of the asset.

If you have Cash flow entered for this stock, do the following

Click the Returns tab

Enter the amount you got after selling all 50 units as Cash Out to see updated IRR
