Technical Presales Question

Hi there,
My team and I are seriously considering purchasing your tax system but we have one major question that we need answered.
We currently have a membership website with a heavy social back end. Thus we collect lots of fields during checkout. Are we able to add fields to your checkout and have them populate our Buddypress profiles?
Is this something that you could help us with? We are looking for something before the end of April so please let us know!
