Hi Tridia Princess_R
I assume the wheat is GST free if nothing has been done to it. The levies would also have be GST free.
For that part it is simple and would be similar to what I do for my vegetable grower and I can do a negative line on my sales invoice.
The Royalties though would most likeley have GST which is what is throwing out both your your sales reported and GST collected account.
You would be best to do a sales invoice for the Gross amount of the sale then receive the payment of the invoice to undeposited funds.
Do a purchase for the royalties and levy deductions and then pay this off from undeposited funds.
Then go to prepare bank deposit tick both entries and the nett figure should agree with what is on you bank statement and all entries will go to correct GST collected and paid accounts, and your sales figure will show as the gross amount and not just the nett amount.
Hope this helps.
