Proof of cash definition
/What is a Proof of Cash?
A proof of cash is essentially a roll forward of each line item in a bank reconciliation from one accounting period to the next, incorporating separate columns for cash receipts and cash disbursements. The columns (and formula) used for a proof of cash are:
Beginning balance + Cash receipts in the period - Cash disbursements in the period = Ending balance

Understanding a Proof of Cash
When used for each line item in a bank reconciliation, the proof of cash highlights areas in which there are discrepancies, and which may therefore require further investigation, and perhaps some adjusting entries. A proof of cash can indicate an array of other reconciliation issues that will require adjustments to a company's accounting records, including the following:
Bank fees not recorded
Not sufficient funds checks not deleted from the deposit records
Interest income or interest expense not recorded
Checks or deposits recorded by the bank in different amounts than what they were recorded by the company
Checks cashed by suppliers that the company voided
Cash disbursements and/or cash receipts recorded in the wrong account
Using a Proof of Cash to Detect Fraud
A proof of cash can uncover instances of fraud. If there is a difference between the totals, it can indicate the presence of unauthorized borrowings and repayments within the time period covered by a single bank statement. Thus, if a controller were to illegally withdraw $10,000 from the company accounts near the beginning of the month for his personal use and replaced the funds before the end of the month, the issue would not appear in a normal bank reconciliation as a reconciling item. However, a proof of cash would be more likely to flag the extra cash withdrawal and cash return within the period.
Advantages of a Proof of Cash
A proof of cash provides a greater degree of detail than a standard bank reconciliation, and so makes it easier to locate errors. Thus, it may be cost-effective to use a proof of cash when you expect to find a large number of different cash-related errors within an accounting period. This means that you could use a standard bank reconciliation every month, and also complete a proof of cash at irregular intervals in order to detect instances of fraud.
Disadvantages of a Proof of Cash
A proof of cash is more complicated to complete than a bank reconciliation. Further, very few software packages include a template that reduces the work required to complete a proof of cash, which means that the proof must be completed manually.
