"Dear sliqtools I am just wanting to say thank you for a great invoicing programme! Since the dark days of Windows 3.11 I have been using an accounts programme 'XXXX XXXX' which, over the years, I have learnt all the features inside out. Recently I purchased a new computer with Wndows 7 and I was shattered to find my old and trusted programme would not operate on the system. I searched the Internet and found most programmes would only support 1 account whereas I needed to run the accounts of 4 organisations. I eventually came across your site, downloaded the trial version and having worked with it for five days I have organised all these accounts and the programme feels like an old friend! So simple and so easy to understand. Thank you sliqtools, you have saved my bacon! Best regards"
