Cash payments how should i handle this

[Momof4]

My families pay in cash too. I bought receipt books at the dollar store for each family and whenever I receive a payment it's recorded in duplicate in the receipt book. At the end of the year I tear out all the duplicates and give them to the parents all at once with a sheet I've typed itemizing all dates and amounts and a total for the year. That way the parents aren't losing the receipts all year long and I don't have to write new ones. And I have exactly the duplicates of everything I have provided to my clients.

My main problem is the fear of having $1000 in my purse on a Friday as I'm making my way to the bank!
