Hi Elon2000,
You certainly don't need Access to do this, but Access could do it. Really, it depends on what you feel comfortable with. I don't like Access because I don't really have much experience with it.
We use SQL instead of Access. You could certainly map your forms to SQL and create a nice Excel report to aggregate them - that's the default demo we do when we show people how our DBXL Web Service works. It allows you to easily map your expense reports to SQL and then you can just create this simple Pivot Table and chart to show the aggregate info. Takes maybe 15 minutes. That's probably your fastest route. Install the DBXL v2.4 Web Service on your local computer (for the local version you will need to download the free version of SQL Express from our YouSendIt site and install that first).
I am guessing you could have this all installed and working in 1-2 hours max. Could take less time. Ted Fitch can show you a quick 10-15 minute demo of the approach and point you to the download sites. Send him email if you are interested. Just e-mail Support at Qdabra dot com and we'll call you and do a live meeting.
Best regards,
