I would agree with you about the costs which are seriously significant when it comes to these mega programs.
My problem is time and hence my needs, although I also realise that learning a new program can take just as long if not longer.
Since my last post I have been looking at Sage and whilst prominently know for accounts, they seem to have an endless array of modules to fit almost type of company in respect of management, product and service which would fit the bill albeit at a huge cost.
The commitment would be very large, so I would still like to explore other options if I can find them, although I do take on your points using MS Office applications.
Many Thanks
