Design, Set Up and Operate Full Accounts Payable Cycle

We are looking for an expert in the Accounts Payable Cycle. We need you to design the accounts payable system for our company that is streamlined and is fraud-proof. We want you to use the systems and processes for a period of time in regular operation to test them and the time it takes to complete the work tracked. All of the processes, time studies and policies need to be written into a manual with supporting training. We have multiple companies. We want them to be brought into this cycle one at a time until all company's A/P cycles are strong and stable.
