Well after so many votes for Quickbooks I decided to give that a proper looksie and after a very short time I was conviced it would be far less time consuming and more user friendly (for a non accounting newb like myself) than MYOB so I bought that yesterday.
Spent last night bashing in the current customer details with my mrs and customising the invoices to look how we want them and I am very impressed with how easy it is to use, this will deffo do us for quite a while and make our job easier I reckon. Even with templates I had configured previously invoices were a pain the ass, this programs made that a lot less hassle already.
