If I were in a meeting with you about what you were doing or could do for me or my company and you consistently replied with 'we can easily look that up' I would cease to work with you - I can hire other people that clearly don't know my business or what they are doing for cheaper.
OTOH, if “we can easily look that up” is never said, it’s likely you’re not asking probing questions. Or that the other side is probably more confident than they should be.
