I cant speak for everyone but on my assesment they didnt ask for anything like that. They do want to see that you have some form of system to manage your paperwork and risk assesment/health and safety policy etc but not material receipts. Im sure some of the others will be along in a minute to let you know if they were asked anything like that.
Ive got my first napit assessment on wednesday, this is what they sent me to make sure ive got everything in order.
