Bookkeeping › Sales & Purchase Ledgers

What is a contra between the sales and purchases ledgers (set-off)?

Intermediate

Answer

A contra/set-off occurs when the same party is both a customer and a supplier. The amount owed can be offset: debit the purchases ledger account and credit the sales ledger account for the lower balance, so only the net is settled. A corresponding entry adjusts both control accounts.
Party owes us 500 (sales ledger) and we owe them 300 (purchases ledger):
  Dr Purchases Ledger (their supplier a/c) 300
      Cr Sales Ledger (their customer a/c) 300
  Net: they owe us 200.
Real-world example A firm both buys from and sells to the same company, so the smaller balance is set off, leaving a net amount.
