Comment 17 for bug 388145

Hi HDA,

please see my latest example a few comments above, where both situations (average and standard price) are given with example bookings, verified with financial books.

a copy of this for the sales invoice (read 2801 => 1310 in this case)
so you may take the average price from the order or when doing a manual invoice from stock, thus price listed on product form.

Invoice customer
account 1310 = C 8,00 (Avarage price from order or when manual invoicing from stock)
account 7000 = D 8,00 Type P/L – Cost of sales

account 8000 = C 30,00 Type P/L Sales account
account 1602 = C 3,57 Type balance – Vat account to pay
account 1300 = D 33,57 Type balance Debtor account

Regarding your proposal to add 2 property fields on product and category, that was my first solution too. It will give the most flexibilty for all countries. Will these properties also be defined in company parameters resulting in defaulting values on product and category?
