Loans, credit cards, lines of credit, equipment financing and mortgages are recorded in Accounting → Debts, separately from the bills you owe suppliers.
Adding one
Each entry takes the type, the amounts, the monthly payment and the start date, with room for notes.
A recurring payment already detected in your transactions can be added here directly, which is the easier path — see recurring payments.
Why it is separate from bills
Supplier invoices are variable and stop when you stop buying. Debt is committed: the payment is due next month regardless of whether the phone rings.
That difference is why the total monthly payment on your debts is worth knowing on its own. It is the floor under your monthly costs — what must be earned before anything else is paid, in a month with no work at all.
The distinction that protects your profit figure
A loan payment is not an expense. Part of it is interest, which is. The rest repays borrowed money, which is not.
Treating the whole payment as an expense understates profit and overstates costs. It is one of the most common bookkeeping errors in small businesses, and recording debts properly here is what avoids it.
What it feeds
The monthly total against your income is debt service coverage, which is the question a lender asks. The balance against what the business is worth is debt to equity.
