Liability
A liability is money owed to someone else, such as a credit card balance or a loan, and it carries a normal credit balance that reports display as a positive amount owed.
In short
What you owe. A credit card charge is a credit to a liability, increasing what's owed — the opposite direction from spending out of checking, which is why it trips people up. Reports flip liabilities positive for readability, even though the ledger stores them as negative internally.
Also called: liabilities, debt
A liability is money owed to someone else — a supplier bill, a loan balance, a credit card's running total. It's credit-normal, meaning it grows with a credit and shrinks with a debit, the same direction as equity and income and the opposite of asset and expense accounts.
A credit-card charge is the clearest place this trips people up: spending money feels like it should be a debit, the way spending out of checking is, but a card charge increases what's owed, and liabilities grow with credits — so the charge itself is a credit, not a debit. Paying the bill later is the debit, since it reduces what's owed.
Reports display liability balances as ordinary positive "amount owed" figures for readability, even though BalanceMCP stores them as negative numbers internally under the debit-and-credit convention. A credit card reads as a positive liability everywhere this happens — the balance sheet and cash_position agree, row for row. The only place a card's debt is signed negative is cash_position's grand total, which nets every card balance against cash on hand rather than just adding the two together.
Liabilities are half of the "financed by" side of the accounting equation, alongside equity — every asset a business holds was either borrowed (a liability) or genuinely belongs to the owner (equity). A rising liability balance isn't automatically bad; trade credit and reasonable loans are normal parts of running a business. What matters is whether the spending behind a liability was actually posted to the right accounts, and whether it's growing faster than income can cover.
What people get wrong
- Recording a credit-card charge as a debit — it's a credit, since it increases what's owed, the opposite direction from a debit-card purchase.
- Assuming cash_position and the balance sheet show a credit card's balance differently — both display it as a positive amount owed; only cash_position's grand total nets card debt against cash.
- Assuming any liability balance is inherently a warning sign — reasonable trade credit and loans are a normal part of running a business.
Common questions
- Why is a credit-card charge a credit and not a debit?
- Because a charge increases what you owe, and liabilities grow with credits. Paying the bill down later is the debit, since it reduces the balance owed.
- Why does a credit card lower cash_position's total instead of adding to it?
- The row itself reads as a positive amount owed, same as on the balance sheet — it's only the grand total that nets card debt against cash, so a card balance pulls that total down rather than up.
