Are invoices paid by check reported to IRS?

Checking to see if we accept checks or point of sale transactions on partially paid invoices are doubly accounted for in tax reports.  Please advise.

Thank you.

The only thing that is reported by Square on your 1099-k is your credit cards processed thru Square.  All other cash and check income would need to be reported by your company's accountant.
