Looking for recommendation for loan servicing software

[Tejas Kotecha]

Hi, 

I recently sold a property with Seller Financing; so I now have Note where I will be receiving payments on. 

I am wondering what do people use for keeping track of these payments, generate receipts and tax forms etc.?

Is it something that I can do on my own? Any software that I can use? Should I rather off-load it to some loan servicing company? How much do they charge generally? 

Thanks
