Age checks at the till
A POS that prompts for age verification on alcohol items and can scan IDs protects your licence. It also creates a record if a sale is ever questioned.
Margins and pricing
Liquor margins are thin, so the effective rate matters. Many customers pay by debit, which costs less than credit if your pricing passes it through. Interchange-plus usually shows the difference.
Fraud on premium bottles
High-value bottles attract stolen cards. Check ID on large card sales and watch for unusual patterns such as several expensive bottles bought quickly with different cards.
Delivery and online sales
Where delivery is allowed, online orders are card-not-present and need ID checks on delivery under local rules. Keep delivery policies clear.
