I have rolled back a year and successfully closed the sale from previous year and opened a new sale for the same customer on today's date and applied credit to it. So far so good.
I went and checked the BAS/GST report for that time period Jan 19 to Mar 19 (the sale was dated feb 19) there is no change in any amounts in the BAS/GST.
What other effect could this sale have on my accounts. I have tried reaching out to my accountant but they are away for XMAS/New year period.
Now i am planning to close the year and move to this financial year but thought I will ask before I do that.
