Hi RHoran
I agree that it should be possible to attach documents to any transaction.
However, in the ean time, what I do is I raise a purchase bill for these items and attach the purchase document to the bill.
If the item is being financed (se with a chattel mortgage) I create a new liability account for the mortgage (I also set it to be a Credit Card type account).
Then wen the finance company pays for the asset, I enter this as a payment for the bill from this loan account. When payments are made to the loan, I treat these as Funds Transferred between accounts.
Hope this helps,
AlanT
