[TYPO3-english] Using Typo3 as an accounting system?

[Dave S]

Hi folks,

I'm working for non-profit whose has a very outdated system for tracking donations from its benefactors based on Microsoft Access 2003. They want to move to a web product (it's only used in-house), but I am very hesitant to build a lot from scratch. A technical consultant suggested using Typo3 to replace the system, by building around it. I am unsure of this however, as Typo3 seems mostly to be for content display only and not ideal for any sort of mathematical operation (such as summing the donations received in a year).

Does anyone have any experience using Typo3 in this or a similar maner? 

Thanks in advance for your time!
