What is a Customer Subsidiary Ledger (SL)?

The Customer Subsidiary Ledger (SL) is a detailed record of all financial transactions between your business and an individual customer. It provides a historical “running balance” that shows every invoice, payment, credit note, and debit note.

​
Why the SL is Important

While the General Ledger shows the total amount owed by all customers, the Subsidiary Ledger allows you to see the specifics for each customer. This is essential for:
  • Resolving billing disputes.
  • Checking a customer’s payment history before extending new credit.
  • Auditing individual account accuracy.

​
What’s in the Customer SL?

Each entry in the ledger typically includes:
  • Date: When the transaction occurred.
  • Transaction Type: Invoice, Payment, Credit Note, Debit Note, etc.
  • Reference No.: The document number (e.g., Inv #1234).
  • Debit: Increases to the customer’s debt (Invoices, Debit Notes).
  • Credit: Decreases to the customer’s debt (Payments, Credit Notes).
  • Balance: The cumulative amount the customer owes after that transaction.
Regularly sending a “Statement of Account” (which is essentially a copy of the SL) to your customers helps ensure both parties agree on the outstanding balance.
