[Glossary](https://blnkfinance.com/glossary) Account normality # What is account normality? Account normality Account normality is which side increases a balance. Debit-normal accounts rise on debit and fall on credit. Credit-normal accounts do the reverse. Assets and expenses are usually debit-normal. Liabilities, equity, and revenue are usually credit-normal. Source and destination name the path of the money. Normality is how each side of that path is signed. ## How does account normality work? You pick a type for each account when you open it. A customer wallet that holds funds is an asset: money in is a debit, money out is a credit. A revenue account is credit-normal: a fee credit raises it. The same transfer can raise one account and lower the other because their normality differs. ## Normality vs source and destination Source and destination tell you which balance loses value and which one gains it in product language. Normality tells the accountant which column moved. You need both if you ever export a trial balance. You can post without saying the word debit, but the sign still exists. | Account | Normal side | Rises when | | --- | --- | --- | | Wallet, cash, clearing | Debit | You receive value | | Payable, revenue, fees | Credit | You owe or you earn | ## What happens if normality is wrong? A fee posted to a debit-normal wallet looks like you paid the customer. A deposit posted to a credit-normal liability you never opened looks like you borrowed. Fix the type on the account before you pile on volume. Blnk posts source to destination and stores credit and debit on each balance. Name wallets as application balances and company accounts as `@` internals so the trial balance has a place for each type.
