FWIW - my sales spreadsheet looks like this:
| Item Description | Sale price | postage received | total proceeds | ebay fee | postage cost | I paid | net profit | sale date |
| | $249.00 | $0.00 | $249.00 | $27.39 | $30.00 | $110.00 | $74.83 | |
I have all my stock listed on the one spreadsheet. At tax time I filter on the sale date to capture the yearly sales for my tax return.
I am sure there are different ways - this is simple enough for me to manage.
I only use Mypost business for postage - which I download the yearly report to tie back into my spreadsheet if I ever have to prove to the ATO my postage costs.
