We have a definied contribution pension plan at my medium-size company. The contibutions are being added to a fund. Then employees can take loans from the fund. It hasn't been administered well, or seperately, and now I'm trying to clean things up.

Does anyone know of a decent fund administration program I can use to keep track of each employees account accurately? Open source or cheap is ideal. Don't have much of a budget. We've been trying to use Excel but it's more than a bit of a mess.
