Cash floats and per diems

Hi there 

I’m a sole trader who is VAT registered. 

Occasionally I am given floats to cover certain expenses when I am working for a company - like taxis, or providing coffees for other people in meetings. I have to reconcile those floats with the company providing them with receipts. I don’t get any paperwork from the company when I’m issued the cash, it just gets paid into my account. How do I deal with these expenses on quickbooks? It’s not income but I do I have to record those cash advances or the corresponding receipts in quickbooks? If so, how? 

Also, when I am contracting away from home for a company, they give me per diems to put towards my food and drink while I’m away. I have to invoice for these per diems - they tell me how much to invoice depending on days away. This is not income per se, so how should I record it in quickbooks? And do I have to put through the receipts from those trips away (paid for by the expenses) into quickbooks? How and where do I do that please?   

thank you!
