3 Regularly review for processing errors
Regularly reviewing your purchase ledger is vital for identifying issues. After all, inaccurate numbers can affect your cash 
flow and reputation. One or two inaccuracies may not cause a huge impact – depending on their value. But, if they are 
allowed to develop over time, your financial statements won't add up, the accuracy will be lost and your cash will not be as 
efficiently managed as it could be.
One thing you can do is look out for ledger debit balances. These can indicate one of the following:
1. Someone made the payment without recording the invoice     2. The business overpaid a supplier     3. There may be 
mis-postings of invoices or payments between on incorrect supplier ledgers.
4 Record the errors
Recording the errors as you go can help pinpoint recurring problems. This will help you review and refine your processes, 
enabling you to maintain more accurate ledger records.
