Why my recently created invoices in Zoho Books in this month (while is only four days (Oct 04)) are showing as profit when I run the Profit and Loss report, but the invoices hasn't being paid yet?, same with previous months. In my type of business I can get paid half o the invoice in one month and the other half in the next month, so when I am running a profit and loss report for sales tax purpose, is making me pay a money I haven't received yet. Am i doing something wrong?
