I have seen the polls for all kinds of software to get the all time favorite of the year. Fun but as a business I have no real use of that polls.

What I need to see is something similar but than with business software that can be used worldwide. So with multiple settings for the different countries.

Example

Software that can make yearly tax reports, make client registration incl. connection to banks to import spendings incl. sending invoices and, making stock reports so on.
Keeping track of and recording driving miles.

And most of all output has to be compatible with global Windows applications so our tax agents can import all data.

I think if you run a business you can fill in your missing "BEST" software.

Best would mean secure to me.

Yes, can be that. But also means workable, modern, simple to use, can be used for more than one thing, modular, multi lingual and so on....
