Seeking recommendations.

A social club where I am a member (and new committee member, for a very new committee) is looking at every expenditure at the moment to try and find ways of saving money.

Their accounting process at the moment, is that bank statements and bills are all sent off to an accountants once a week, who deals with everything.

Since at the moment we don't have a treasurer, I want to propose that the treasurers roll be expanded to handling simple accounts. (keeping a purchasing/invoicing tally, bank statement reconcilliation etc.) to reduce the burden on the accountant. (At the moment, the treasurers only role is to handle Payroll).

Can anybody recommend any software that is well suited to this purpose, I am experienced with Sage Line 50, but in my head I can't see how this would be the best approach.

On another note, I am the IT Administrator for a company that deals with manufacturing paints and powders, we have been using Line 50 since it was a DOS application. This is used for purchasing, sales, stock control, invoicing , accounting etc. And with a few tools I've written, helps our sales reps see live stock figures and account status.

Can anyone recommend a more multi-user friendly package that can handle all these things, prefereably using a proper DBMS so that I can use it from VPN connected machines on other sites?

Thanks in advance for any help.
