How do you record interest charged to a slow-paying customer?

Intermediate

Answer

Interest charged on an overdue customer account is income: debit the customer's account in the sales ledger (increasing what they owe) and credit interest income (or a sundry income account). It also increases the receivables control account. It's usually recorded via the journal.
Charge 25 interest: Dr Customer (sales ledger) 25; Cr Interest Income 25.
Real-world example A late-paying customer is charged interest, increasing their balance and recording income.
