- Compass bartender only service starts at $550. Trailer packages are quoted to your date, location, guest count, and hours.
- The alcohol is separate: Compass runs BYOB, so you buy bottles at retail and keep the leftovers.
- Three trailer packages by guest count: Classic (1 to 35), Signature (36 to 64), and Plus (65 to 100 and up).
- Every trailer package includes the trailer, bartenders, a custom menu, mixers, ice, cups, garnishes, coolers, and setup and breakdown.
The Short Answer
At Compass, bartender only service starts at $550. Trailer packages are quoted to your date, location, guest count, and hours, so the fastest way to an exact number is to send your date. The alcohol is not part of the quote: Compass runs BYOB, which means you buy the bottles at retail and the quote covers everything else.
That last part is the one that surprises people, and it is the reason a mobile bar usually costs less than they expect. The rest of this guide is what goes into the quote, what comes with it, and how the BYOB math works.
What Moves The Quote
Four things set the price of a trailer package.
The Three Trailer Packages
Compass Classic, 1 to 35 guests. Showers, birthdays, and small backyard gatherings. The full trailer setup, one bartender, and complete menu design.
Compass Signature, 36 to 64 guests. The middle sweet spot: most weddings, corporate events, and big family parties, staffed and stocked to keep the line moving.
Compass Plus, 65 to 100 and up. Large events, with extra bartending staff, high volume prep, and a service plan built so the bar never becomes the bottleneck.
Every trailer package includes the trailer, professional bartenders, a custom drink menu, mixers, ice, cups, garnishes, coolers, and setup and breakdown. Just need a bartender and no trailer? Bartender only service starts at $550.
The BYOB Math
Here is why BYOB matters for the total. When a venue or caterer runs the bar, the alcohol is priced into a per person package, with their markup on every pour. With Compass, you buy the bottles yourself at retail prices, from a shopping list sized to your menu and guest count, and whatever is not opened stays with you.
For a sense of scale, the alcohol calculator puts a 100 guest, five hour party at about 550 drinks: roughly 220 beers, 22 bottles of wine, and 14 bottles of liquor for a full bar. Price that at your local liquor store and you know exactly what the alcohol side costs before you book anything. The BYOB guide explains how the shopping list gets built.
Getting An Exact Number
Send the date, the town, a rough guest count, and how long you want the bar to run. We confirm the date is open, match you to a package, and come back with a quote for your exact event. If you are still comparing options, the trailer bar vs. caterer's bar comparison lays out how a trailer bar stacks up against a caterer's bar and doing it yourself.
