Reconciliation of the general ledger to sub-ledgers is
another type we will review. The general ledger (or simply "ledger"
or "G/L") is a collection of all balance sheet and income statement
accounts. The general ledger also includes all journal entries posted to
accounts. In nowadays' computerized world, the ledger is maintained in an
electronic form.
A sub-ledger is a detailed record of transactions for an
individual account. Usually, a sub-ledger contains detail of transactions for
an account, which are summarized by day (or month) and the total is then posted
to the general ledger. Therefore, sub-ledgers serve as support for amounts
posted to the general ledger. Sub-ledgers are presented in an electronic form
as well (e.g. Excel file, detail of an account in QuickBooks, SAP or Oracle).
For example, accounts receivable sub-ledger may contain detail for all issued
invoices and cash receipts. At the end of a day, an accountant can summarize
all invoices issued (sales) and cash receipts (cash collections) and post them
to the general ledger in two separate journal entries. The general ledger would
not contain detail for each individual transaction.
As there is always room for a human error, it is important
to reconcile the general ledger balances to the sub-ledger balances on a
periodic basis to spot such errors. If there are no errors in posting journal
entries to the general ledger, then the two balances will match; however, if
there are differences, then there would be reconciling items, which need to be
analyzed and corrected, if necessary. Two important accounts that should be
reconciled on a monthly basis are accounts receivable and accounts payable.
Sometimes items (amounts) are included into a sub-ledger,
but not in the ledger. Vice versa, items (amounts) may be posted to the ledger
via a journal entry, but not recorded in the sub-ledger. Such items should be
identified on the reconciliation separately to ensure they are given proper
treatment.
Step 1: Compare G/L balance to the sub-ledger balance
You should start by analyzing the G/L and sub-ledger
balances to identify any differences. While doing that, pay special attention
to the transactions that are unusual in their nature. For instance,
non-recurring transactions may have a higher risk of an error than transactions
completed on recurring and regular basis. You should examine the sales journal
(for receivables) and the purchases journal (for payables); have a look at
posted entries, which were posted to the wrong account, transactions posted
twice (duplication error), transposition errors, etc. Then you should look at
the cash receipts and cash payments journals (for receivables and payables,
respectively). Possibly, you will need to repeat with your examination of the
invoice register for accounts receivable and the purchase order journal for
accounts payable.
Step 2: Investigate reasons for the difference
After you have compared the G/L and sub-ledger and found
differences, you should investigate reasons for them. Reasons for the
difference can include the following:
Items posted to G/L, but not in sub-ledger
Items posted to sub-ledger, but not in G/L
Errors
Step 3: Adjust G/L and/or sub-ledger
The next step is to make necessary adjustments to the G/L or
to sub-ledger(s) based on the reconciliation to correct any errors, omissions,
etc. To identify what needs to be adjusted, you could use the template of the
general ledger to sub-ledger reconciliation statement presented above.
Step 4: Compare adjusted balances
Finally, compare G/L balance to sub-ledger balance again,
after all necessary adjustments were made. If reconciling items are resolved,
the reconciliation process is completed. If there is a difference, continue to
examine the sub-ledger and journals that are a part of the revenue and
expenditure cycles to identify the problem and correct it.
