I wrote my first computer program in 1976, and have been involved in the software industry for most of the time since then. I am also qualified to master's degree level in computer usability.
I now work as a technical author and usability consultant, which entails playing around with software or hardware (without the benefit of an instruction manual) until I get a deep understanding of how it works, and then writing user instructions in clear and simple English whilst feeding back suggestions on usability improvements to the software engineers. In short, I have a fair bit of experience, and know good software when I see it.
Sage Instants is, without any doubt whatsoever, the nastiest piece of software I have come across in my 30+ years in the industry. I started using this stinking pile of dog-poo six months ago simply because it is my accountant's preferred method of submitting my accounts. He has now agreed to accept my accounts on a spreadsheet, and that is what I shall be doing. Quite frankly, I'd sooner use an abacus than this wretched software.
There is a half-decent online tutorial included with the software; it took me ten solid hours to work through every lesson. Sadly Sage seem to think that a decent tutorial system will compensate for unusable software. It doesn't. It simply means you have unusable software with a decent tutorial system.
The one redeeming feature of Sage's product is the helpfulness of Louise(?) on the Help desk. However, the sheer number of pre-written help sheets to which she has access (and which she will happily email you) merely indicates how many problems Sage's users have had over the years.
My only advice, should you decide to buy this, is to take a backup **every single time** you exit. And don't ever leave more than an hour between exits/backups. You might think that if you get yourself in a muddle, you'll be able to exit without saving, and simply try again. You'd have thought so, wouldn't you? After all, all software allows you to do that, doesn't it? Sorry, even such an elementary feature seems to have been beyond the bright sparks who designed this system.
You have been warned!
