Self-buy cuts liquor-store margins but adds logistics—here’s how to decide if it’s right for you.

Buying alcohol for wedding: the short answer

You can buy your own alcohol for a wedding, but you must first confirm your venue allows it and that a licensed bartender will serve it. Then you need to calculate quantities based on your guest count and drink preferences, using a per-person estimate from your own bar plan. Factor in return policies on unopened cases and delivery logistics. This approach gives you control over selection and cost, but requires extra coordination.

Where this usually goes wrong

Each of these is cheap to avoid now and expensive to fix later. They are the mistakes that surface in the final invoice.

Watch for

  • Buying alcohol without checking venue policies first, then having to discard or store it.
  • Over-ordering without a return policy, leaving you with hundreds of dollars of unused bottles.
  • Forgetting to budget for bartender service fees, ice, and glassware rentals.

Questions about buying alcohol for wedding

Do I need a license to buy alcohol for my wedding?

No, you don't need a license to purchase; you need a license if you sell. However, your venue may require a licensed bartender to serve.

Can I return unopened bottles if I buy too much?

Policy varies by store. Always ask before purchasing and get it in writing.

How much alcohol should I buy per guest?

Use a drink-per-guest estimate based on your guest list and known preferences, not a generic percentage. Calculate by number of drinks, not by cost.

Where to go next

Once you decide to buy your own alcohol, compare the pros and cons of hiring a bartender versus a full bar service.
