Coffee cart operators run mobile espresso and drip coffee service at weddings, corporate events, office mornings, farmers markets, film sets, and private parties. Most invoices go to event planners, businesses, and hosts who book a set service window and pay for the cart, the staff, and the drinks served.

Most coffee cart work is priced as a package: a flat fee or hourly rate for a set service window (usually 2 to 4 hours) that includes the cart, a barista, setup, and breakdown. Many operators add a per-guest or per-drink rate when the host wants a guaranteed number of drinks, or a minimum spend that covers the booking if attendance is low. Hosted events are typically billed in advance by guest count or time. Pay-as-you-go events, where guests buy their own drinks, usually have a guaranteed minimum or booking fee that you collect from the host. Extras such as travel, additional baristas, specialty syrups, oat or almond milk, custom cups or sleeves, and late-night or holiday service are billed as separate line items. Recurring office or weekly accounts are often billed monthly with a set per-visit price.

Notes: Event date: Thursday, May 15, 8:00-11:00 AM. 50% deposit of $474.00 was received on booking; balance due within 14 days of the event date. Guest count was billed at the final number confirmed 3 days before the event. Payment accepted by ACH, check, or card (3% fee on card payments).
Ties the charge to a specific booking and settles disputes about how long you were serving versus setting up.
Hosted events are often billed per guest or per drink, so the client needs to see the number that drove the total.
Shows the booking deposit was applied and prevents double payment or confusion over what remains.
Add-ons are the most common source of pushback; listing them separately makes the total easy to defend.
If the event ran past the booked window and the host asked you to stay, a clear line item documents it.
Prepared drinks are taxable in many states, and rules differ for catering versus walk-up sales, so check your local rules and show tax on its own line.
Corporate venues, event planners, and some venues ask for proof of permit and insurance details for their records.
Most coffee cart operators take a non-refundable deposit of 25 to 50 percent to hold the date, with the balance due on or shortly before the event for private parties, and net 14 to net 30 for corporate clients. Weddings and large events are often paid in full a week before. Recurring office accounts are usually invoiced monthly or at the start of each month. Late fees of 1.5 percent per month are common if stated in advance. Accept ACH, checks, and cards; if you pass on card processing fees, say so in your booking terms.
Set a deadline, usually 3 to 7 days before the event, after which the guest count cannot go down. Bill on that number or the actual count, whichever is higher, and put it in your booking terms.
If guests buy their own drinks, a slow crowd can leave you with a lost day. A booking fee or guaranteed minimum sale, collected from the host, covers your labor and travel regardless of turnout.
A 2-hour service window usually means 3 to 4 hours of work with loading, drive time, and cleanup. Build that into the package or charge a separate setup fee so short events stay profitable.
Alternative milks, specialty syrups, and custom-printed sleeves cost more than standard supplies. Offer them as upgrades with a set price instead of absorbing them.
Send it while the host is still happy with the cart and the guest count is fresh. Include a payment link or clear payment instructions.
Both are common. Hourly or package pricing is simpler and protects your time. Per-drink or per-guest pricing works when the host wants to cap spend or you cannot predict volume. Many operators charge a base package plus a per-guest rate above a certain count.
It depends on your state and how the sale is structured. Prepared drinks are taxable in many states, and catering service fees may be taxable as well. Check with your state department of revenue or a tax professional, then show tax as its own line.
If your booking terms say the deposit is non-refundable and the client signed or accepted them, you can usually keep it, since you held the date. Terms that spell out cancellation windows and what is refundable avoid most disputes.
Tips left directly by guests belong to you and your staff and are not part of the invoice. If the host adds a gratuity, list it as a separate line so it is clear it is not part of the service fee. Tip and payroll reporting rules vary, so check with your accountant.
Charge your additional hourly rate and note the actual end time on the invoice. It helps if the host agrees to the extension, even by text, before you keep serving.
