Indépendant Contractor Reimbursements

Hello,

I am a cleaner, I clean an office where I have been fronting supplies (toilet paper, trash bags, paper towels, etc) with my personal credit card(bad idea I know, they always reimburse very late).

The client did not itemize expense reimbursements, instead lumped them into my wages. I itemized supplies on my invoices. Do I need to reach out to the client to correct this? I do have records/receipts of every single purchase. I know I can deduct my own business expenses that I pay for, such as gas, but shouldn't supplies reimbursed be itemized separately?? Thank you so much
