Nominal Ledger Explanation
Previous Top Next

The nominal ledger is the central core of the accounts.  It records information from the sales and purchase ledgers since the transaction entry programs in Gx Sales and Gx Purchase automatically update the correct nominal accounts.  In addition, it is necessary to record and update transactions that do not come from the sales or purchase ledgers.  For example, where there are no customer or supplier records to update, you can record the information directly into the nominal ledger using journals. Petty cash is an example of this.  You would not create a Purchase Ledger supplier account for the local shop where you buy milk, stamps etc since you do not wait to be invoiced for such items.  Instead you can post the amounts spent straight into the relevant nominal accounts, e.g. petty cash, sundries, postage etc using the nominal Cash Book Journals program.  Employee wages is another example.  These can be posted directly to the nominal ledger using Nominal Journal Postings since they do not relate to sales or purchases. 

The nominal ledger is split into two parts: the Balance Sheet and the Profit & Loss account.    

Balance Sheet
This is always ongoing.  It contains details of your assets (e.g. debtors, bank account, cash in hand, stock) and liabilities (e.g. creditors, bank overdrafts, loans, VAT).  The balance sheet will also include depreciating assets, e.g. vehicles, equipment and machinery. 

Profit & Loss
This includes income and expenditure.  It is cleared at the end of the financial year.  The profit or loss made is calculated at the financial year-end and added to the balance sheet.  The P&L begins fresh for the new financial year. The P&L has three main sections Sales/Income, Purchases/Cost of Sales and Overheads/Expenses.

Double Entry Postings
Power-Gx operates double-entry booking-keeping.  All postings in the nominal ledger need dual entries, i.e. a debit and a credit posting so that the batch control total is always zero.  This ensure that money does not ‘disappear’ from the system, it must increase one account and decrease another leaving an audit trail.  Credit entries usually represent the sources of financing, and the debit entries usually represent the uses of that financing.  Examples include:

Buying an asset:
1.   The amount of fixed assets in the business increases (debit).
2.   The amount of cash in the bank is reduced (credit).

Entering cheques received from your customer:
1.   The bank balance is increased (debit).
2.   The debtors account is decreased (credit).   

Wages paid directly into an employees account:
1.   The bank balance is reduced (credit).
2.   The wages and salaries overhead nominal account is increased (debit).       

Accounting for stock used internally:
1.   The stock value is reduced (credit).
2.   The office/admin overheads are increased (debit). 

Double-entry journals enforce built-in checks and balances that help you keep accurate records.  Refer to Debit or Credit Journal Entries? for guidance on which entry should be the debit (+ve) and which should be the credit (-ve).

Nominal Account Codes
On Power-Gx, nominal account codes are made up of ten digits split into three parts; Branch, Section and Cost code.  These are arranged as follows:

BBB/SSS/CCCC

Branch Codes
The branch determines whether this nominal code is a Balance Sheet item or Profit & Loss account item.  A company can have up to 999 branches, with code 000 being reserved for the balance sheet.  It is most likely that they only use 000 and one P&L branch code, 001.  However, you can replicate the P&L by using multiple branches. 

Section Codes
Section codes will be allocated to Current Assets, Fixed Assets, Liabilities, Sales, Purchases, Overheads and so on.  Examples of the section codes you could use are:

E.g.     Fixed Assets                         010
            Current Assets                      020
            Liabilities                               030
            Sales                                      100
            Purchases                             200
            Overheads                            500

The above figures are just examples of the section codes you could use. Your company will have its own codes in place.  However, it is a good idea to use gaps in the numbering as suggested above so that any new section codes required can be slotted into the required places so that the trial balance prints in a sensible order. 

Cost Codes
Cost codes are given to the various items in the accounts.

E.g.     property                                 0100
            plant and machinery0110
            motor vehicles                      0120
            debtors                                   0200   
            bank                                       0210
            creditors                                 0300
            sales of stationery                1000
            sales of furniture                   1010
            rent                                         5000
            utility bills                               5010
            
Again these cost codes are simply suggestions.  You may wish to follow a sequence of allocating cost codes a number that ties in with their section code. 

E.g.     section code 010 uses only cost codes 0100 – 0199
            section code 020 uses cost codes 0200 – 0299
            section code 100 uses cost codes 1000 – 1999
            section code 200 uses cost codes 2000 - 2999
            section code 500 uses cost codes 5000 – 5999 and so on. 

Such a system makes it easy to determine the next available nominal code for a new item.  Click here for an example of a well planned nominal account code structure.

The combination of the branch code, section code and cost code creates the unique nominal account code.  For example using the codes suggested above, the P&L sales code for stationery would be 001/100/1000 where 001 represents the P&L, 100 is the sales section code and 1000 represents the sales of stationery cost code.  Nominal account code 000/020/0200 would represent Balance Sheet/Current Assets/Debtors and nominal account code 001/500/5000 would represent P&L/Overheads/Rent.

Debit and Credit Accounts
Nominal account codes are either debits or credits.  It is important to set the nominal codes up with the correct debit or credit indicator.  Assets, sales discount given, cost of sales, overheads and other purchases are debits. Depreciation of assets, liabilities, sales, other income and purchase discount taken are credits.
