Card spending creates a record
Card transactions are easier to reconstruct later, but the bank description may not explain the purpose. A short category or note keeps the record useful.
Cash spending needs intention
Cash withdrawals are not expenses by themselves if the cash is still in your wallet. Record the purchases made with cash, not both the withdrawal and every purchase.
Choose one consistent method
For small cash spending, some people track a single weekly cash category. Others record each purchase. Choose the level of detail that you can maintain.
Avoid double counting
Transfers between your own accounts and cash withdrawals move money; they do not automatically represent spending. Treat them separately from expenses.
