We decided the Audit Programme as under;

1. Purchase Department.

2. Accounts Department w.r.t Bank payments.

3. Accounts Department w.r.t Cash Payments.

The Internal Audit methodology decided as under;

b) Verification of systems, internal controls, vouching.

c) Observations.

d) Discussion of our observations with Department.

e) Discussion with management.

Each one of the methodology is undertaken as explained in brief as follow:


The questionnaire is set for the interview of the Department head to ascertain the internal control systems followed by the Department.

The main questions are:

 i) The starting point of the function.

ii) Activities involved in the Department.

After the interview the basics of internal control followed in the dept is  ascertained.


Verification of the internal control as explained in the interview to ascertain its effectiveness, efficiency, deficiencies, gaps, feedback, period required , etc. The verification process required the vouching of evidences related to each transaction in the dept.

I recollect the vouching has following basics.

To verify the date with in the audit period.

The account heads are properly mentioned.

Voucher attached with proper evidence, supporting.

The voucher/Invoices/ supporting should be in the name of company. The voucher is properly authorised and duly signed by recipient.

Cash payments have revenue stamp whenever applicable.

It means the transaction should be as per the voucher.

I now called the above method of vouching is First Generation Method.

The Second Generation Method of vouching consists of,

Activity     To verify
1.Restrict to the period of Audit.   Period
2.List Complete Set of documents.   Set
3.Ascertain the Sequence of documents.     Sequence
4. Reference check.     Reference

Now a days both the FGV First Generation Vouching and SGV Second Generation Vouching is required to ascertain the internal control effectiveness and existence.

Sequence check is checking of sequence of preparation of documents in ascending or  descending order. In purchase Department the sequence should be Purchase Requisition, Purchase Order, Order Validation, Issue of Purchase Order, Receipt of Martial, Quality Check, Approval of Documents, Submission to Accounts, Verification of Credit terms, Payment to Suppliers, Receipt of Payment. This will help in ascertain odd sequence in the internal control system.

A Reference check may be checking of reference of previous document to subsequent document, and unique reference number for all documents. The  Purchase Order Number should be on all the above documents. Invoice should contain the Purchase Order Number and date of the Order.

Frequency checks to ascertain number of days from one purchase to another this will help to ascertain excessive or shortage in stocks then required.

The capacity check is checking of balance of stock vis the storage capacity.

The odd transaction from above transaction is the query to ascertain the internal control.


After the vouching as above, the observations should be noted w.r.t. the  internal control weakness if any.

The observation on purchases may be as under:

Inward /Receipts of the material in stock matches  with the ledger of the supplier. Number of entries for purchases matches with number of receipts in the stock ledger of the item.
