Any one a small receipt scanner for small biz?

So I am at the CPA last weekend and he says even though I have A Credit card monthly statement for my “parts for resale” I need to keep the receipts for proof. Orginals don’t last due to damn soy ink they use in printer now. I say 3 months and they are fading let alone last 7 years. Also I think, “That’s funny because for 26 years the CC monthly statement was proof, but under this new administration and the 86,000 new agents… he worried it was not good enough and told me to go get a portable scanner for receipts and to log them by the day. Sounded good until I started searching. Anyone else with a business using a portable scanner for reciept tracking and what software are you using.
Thanks!
Joe
