The Key Issues in invoice processing are.
High operating cost
The operating cost incurred in invoice processing is mainly direct costs, which refer to the costs of physically processing invoices; printing and mailing them; indirect costs, which refer to the expense of hiring employees to process the invoice details (enter, update, and archive all invoice data); and additional expense, which refer to the negative cash flow created due to an invoice lag or delay.
Inaccurate data
