I bought Quickbooks 2005 and used it for a number of years. It ran well and worked well. I had the advantage of doing accountancy for 4 years as a job many moons back. But as Windows got further and further updated, the product stopped working.
I think accounts packages are just online and your books are on the cloud, so you just pay to keep using it. Unless you are or want to go VAT registered, or you want to analyse different incomes and expenditures in detail for some reason, I see little point in accounts packages. For wages, I just use the HMRC RTI software. Come accounts time, I just download my bank transactions for the year, copy and paste them into my spreadsheet and I simply put a letter beside each transaction and that value pops into specific columns. Then I just file my CT600 online by taking these values from the columns.
I initially used Quickbooks to analyse every thing out, then as time went on, there was absolutely no benefit gained.
Do you have a particular concern, question, interest with Quickbooks?
If I install Quickbooks 2005 on an Windows XP, it works grand. But you have to leave it open because after 5 or 6 times of opening and closing it, I would have to phone Quickbooks to unlock it. Those were the days to stop piracy.
