Ignore my reply about the task field. I wasn’t understanding before how the custom fields work but now I see you can create a custom field for each section…Invoice, Expense, Task etc. and you can choose whether or not that appears on the invoice or not. So by adding a custom product field (cost price) and not showing it on the invoice, when exporting the CSV report for product and doing some math to deduct it from the sale price, it works as I intended. Would be great to have the ability for cost price/sale price in the future built right into InvoiceNinja, but for now I can export reports and calculate my gross/net profit manually. Thanks for the help.
