i) He should examine first the internal control system in connection with purchases and satisfy himself with regard to its effectiveness.
ii) He should ensure that before passing the invoices for payment, they are checked with the original order, with goods received book and the stock records.
iii) He should inspect the invoices and see that the authorities responsible for passing them for payment have duly checked them and initialed.
iv) He should test check the invoices to see that dates given in the invoices are for the period concerned and they have been addressed in the name of the client.
v) He should also compare a number of invoices with the records in the goods received book and stock records.
vi) He can make physical verification of the goods purchased, if a part of it is still in the stock.
vii) He should also compare the supplier‟s statement with the supplier‟s account.
