Preface :


Dhruva is a Practice Director — Data Analytics with M/s.
Assurance & Associates. M/s. Assurance & Associates are Practice leaders in the
field of governance, risk management and control analytics for the last 5 years.
In a short span of 5 years this dynamic firm had managed to establish a
footprint in the accounting and finance segment which was the erstwhile arena
for large accounting and audit majors. This fast-paced growth was fuelled by a
small group of ‘razor sharp’ smart professionals who delivered consistent value
propositions to all their clients by riding on the backbone of contemporary
audit technology.

M/s. Assurance & Associates leveraged audit technology like
general audit softwares, audit administration tools and enterprise risk
management applications to deliver above-the-board, high-return results to all
the clients from retail to manufacturing, to logistics and healthcare.

Dhruva was solely responsible for overseeing all data
analytic projects, assignments and academic ventures for the firm.

In a recent meet of mid-rung audit firms, Dhruva was
presenting on the role of ‘The Power of Analytics’ and ‘Analytics made Simple’.
Dhruva spoke firmly, confidently and charismatically about his association with
general audit tools and the outstanding benefits which accrued to him and the
firm over the last 5 years through the power of analytics. There was a twinkle
in his eye as he drew a colorful picture about his journey with general audit
softwares. His oration captivated the audience and laid the foundations for
prolific use of CAATs by all audit firms in the days to come.

Dhruva presented on general audit softwares and their lineage with
manufacturing entities :

Manufacturing companies have many of the standard ledgers;
purchasing and payroll can be key concerns. However, the main business area is
inventories.

Inventories (stocks) and work-in-progress :

There is normally a master or balances file that contains
details of inventory holdings at a particular date. Costs may be held in a
separate file. Transaction history can be particularly useful although file
sizes are often quite large. Selling prices normally have to be picked up from a
separate file.


Tests conducted included, but were not limited to :


Analysis :


  • Age stock by date of receipt



  • Compute the number of month’s stock of each item held, based on either sales
    or purchases. Produce a summary of this information



  • Stratify balances by value bands



  • Statistically analyse usage and ordering to improve turnover



  • Summarise products by group, location, type, etc.



  • Report of products in order of profitability



  • Reconcile physical counts to computed amounts




Calculations :


  • Total the file, providing sub-totals of the categories of inventory



  • Re-perform any calculations involved in arriving at the final stock quantities
    and values

  •  Re-perform material and labour cost calculations on assembled items




Exception tests :


  • Identify and total stock held in excess of maximum and minimum stock levels



  •  Identify and total obsolete or damaged stock



  • Identify any items with excessive or negligible selling or cost prices



  • Identify differences arising from physical stock counts



  •  Test for movements with dates or reference numbers not in the correct period
    (cut-off)



  • Identify balances which include unusual items (e.g., adjustments)



  • Identify work in progress which has been open for an unreasonable period

  •  Identify stocks acquired from group companies



  • Isolate products with cost greater than retail price, with zero quantities or
    with zero prices


Gaps  and duplicates:

  • Test for missing stock ticket numbers
  • Test for missing transaction numbers
  • Identify duplicate stock items


Matching and comparing:

  • Compare files at two dates to identify new or deleted stock lines or to identify significant fluctuations in cost or selling price
  • Compare cost and selling price and identify items where cost exceeds net realisable value
  • Compare value of physical counts to generate ledger amounts
  • Check work orders for accuracy against original sales orders


Other typical areas of tests include:


Cash disbursements:

  • Reconcile intercompany transfers
  • Summarise cash disbursements by account, bank, group, vendor, etc.
  • Generate vendor cash activity summary for contract negotiations


Purchase orders  :

  • Extract pricing and receipt quantity variations by vendor and purchase order
  • Track scheduled receipt dates versus actual receipt dates
  • Identify duplicate purchase orders or receipts without purchase orders
  • Reduce inventory by comparing projected receipts to available stock
  • Analyse late shipments for impact on jobs, projects or sales orders due
  • Reconcile receipts by comparing accrued payable to received items


Work-in  progress:

  • Use net demand  analysis against inventory  and purchase orders to generate a quick material requirement planning report
  • Check work orders, by size, priority, for lease to shop floor
  • Produce  shop floor activity report by any item
  • Generate comparison of planned versus actual labour, materials and time
  • Reconcile job tickets or time cards to work order line items


Dhruva glorified general audit software and its power in working analysis with retail entities:

Retailers often have point-of-sale systems which collect large volumes of useful data which audit tools can analyse. The main tests on inventories are similar to manufacturing companies with perhaps more emphasis on movement, margins and shrink-age.

Additional  tests include:

  • Gross profit  analyses
  • Items past  their shelf life
  • Comparisons between stores on holdings and inventory turnover per product line
  • Price adjustment transactions


Other typical areas of tests include:


Cash  disbursements:

  • Identify potential fraudulent or improper transactions through selling price differences between stores


Purchase order management:

  • Reconcile order received to purchase order to identify shipments not ordered
  • Extract pricing receipt quantity variations by vendor and purchase order
  • Track scheduled receipt dates versus actual receipt dates
  • Compare vendor performance by summarising item delivery and quality


Compare accrued payable to received items to reconcile to general ledger

Distribution and  Service:

Typical areas of tests include:

  • Analyse open orders and open invoices by customer for credit control
  • Isolate detail and average backlog by customer, item, location, etc.
  • Reconcile booked items to inventory reserved (on hold) items

Brilliant ending:

Dhruva received a standing ovation from the group. He ended his presentation in all humility by citing that General Audit Tools are time-tested, stable, robust, powerful, internationally acclaimed and user-friendly applications. He added that no Tool is a ready substitute for the auditor’s acumen and judgment, but is a powerful, cost-effective facilitator. He encouraged all the members present to embrace Tools and reap the benefits of an idea whose time has come.
