At the end of an accounting period, a bookkeeper will post the totals of the columns of its Purchases Day Book (“PDB”), its Purchases Returns Day Book (“PRDB”) and its Discounts Received Day Book (“DRDB”) to the General Ledger.
DAY BOOK | INFORMATION RECORDED IN THE DAY BOOK |
PDB | Information from purchases invoices received from credit suppliers |
PRDB | Information from purchases credit notes received from credit suppliers |
DRDB | Information about prompt payment discounts received or taken from credit suppliers |
a) The Purchases Day Book (“PDB”)
The column totals of the PDB record changes to the following liabilities and expenses of the business:
- The total of the gross column records an increase in the business’ liabilities, specifically the amount of money it owes to its credit suppliers (i.e. the suppliers who provide it with goods and services on credit terms)
- The total of the VAT column records an decrease in the business’ liabilities, specifically the amount of VAT owed by the business to HMRC
- The total of the net column(s) records an increase in the business’ expenses, which could be purchases of raw materials or goods for resale or other types expenses incurred in the period
Posting list from the PDB to the General Ledger
The column totals will be posted as follows to the General Ledger
- The Gross column total will be recorded on the Credit side of the Purchases Ledger Control Account (i.e. the account where we calculate how much is owed by the business to its suppliers)
- The VAT column total will be recorded on the Debit side of the VAT Account (i.e. the account where we calculate how much the business owes in VAT to HMRC)
- The Net columns of the PDB will be recorded on the Debit sides of the appropriate expense account (i.e. the accounts where we calculate the value of the different types of business expenses in a period); e.g.
- The net cost of raw materials or goods for resale would be posted to a Purchases account
- The net cost of advertising would be posted to an Advertising account
- The net cost of motor expenses would be posted to a Motor Expenses account
- And so on…
