VAT included or excluded?

ElizaBatty

Hi all,

I am working my way through Bookkeeping Transactions and for VAT examples, in the Purchase Order it is excluding VAT but in the Sales Invoice, it is including VAT.

What is the reasoning behind it being excluding for one, but including for the other? Or can it be interchanged and this is just how the book has done it for an example?

Thank you!
