Tags are like Categories. There is no limit on how many you can add per receipt. Use them for content grouping eg. "Lunch" for meal receipt or "Medical" for prescription drugs. It is that easy.
Correctly tagging your receipts will also:
- Allow you to find them faster in the app's search,
- Group common receipts for charting & comparising expenditures/price flactuations and
- Empower you with detailed Ledger Expense Reports.
