Hi fivegeesewines
As you can see MYOB posts all sales of the same item to the one GL Income account.
However the GL is not the only place you can track things like the type of Customer or Market you sell into. Infact I would suggest that if using MYOB the GL is most definitely not the best place to do this type of tracking.
I would not recommend changing the GL account attached to an item prior each sale, that is not efficient and will be prone to error.
You can determine if each Customer is an Export or Domestic customer when you setup the Customer Card. Simply setup a Custom List called Customer Type and allocate each Customer to either Export or Domestic. See link below for how to use Custom Lists.
Then invoice all wine sales using the one Item for each product.
You will be able to run a Customer Sales report in MYOB and Filter to select only Export Customers etc.
You may also like to look at the Advanced Reporting MYOB App Market Place for addon solutions that also provide very flexible reporting over Sales, Inventory, Margins etc
As an example our Business Intelligence solution BI4Cloud will let you report over Sales and Margins by:
- Customer and Item Custom lists
- Customer Location ( State, Country)
- Salesperson etc.
See the following links for more details.
I hope this helps.
