Other accounting systems allow you to choose a tax code when posting journals, if I need to do adjustments I can't currently do so.
The vast majority of journals would be no VAT but things like the Tour Operators Margin Scheme on trips, we need to pay VAT on the profit, in other systems you would Dr Sales by the profit amount with no VAT and Cr Sales by the profit amount inclusive of VAT.
Another example is our external caterer takes sales on our behalf and credits our bill with exempt income, we cannot process this in the iFinance system at present.
It seems that most of iFinances work arounds need to be done both on the sales and purchase ledgers with dummy customers/suppliers.
