An event planner is the one person who has a contract with the client and a working relationship with every vendor, which means you are the first person blamed when the caterer is late or the band overruns. A good contract draws the line between what you control (the plan, the timeline, the coordination) and what you don't (a vendor's performance, the weather, a guest list that grows by 40 people two weeks out).
This template is written for corporate event planners, party planners and day-of coordinators. It covers the commercial terms most disputes come down to: the planning fee, the vendor relationship, the guest-count lock date, event-day hours, and what the client owes if the date moves or the event is cancelled.
TL;DR
The event planning contract template covers services, planning fee and payment schedule, vendor contracting and commissions, a guest-count lock date, event-day hours with an overtime rate, tiered cancellation, postponement, and liability limits for vendor failures. Send it right after the client accepts your proposal and before you contact any vendor. Collect 25-50% on signing and the balance two to four weeks before the event.
What's inside
- Event details — date, venue, expected guest count, event type and your point of contact.
- Services and service level — full planning, partial planning or day-of coordination, with what each includes.
- Planning fee and payment schedule — flat fee, percentage-of-budget or hourly, with deposit and balance dates.
- Vendor management — who signs vendor contracts, who pays them, and how commissions are disclosed.
- Client decisions and deadlines — guest-count lock date, final timeline sign-off and late-change charges.
- Event-day terms — on-site hours, staff headcount, overtime rate, meals and breaks for your team.
- Cancellation and postponement — a tiered schedule based on days before the event, plus one-time date-change rules.
- Liability, insurance and conduct — vendor failures, venue damage, alcohol service and guest behavior.
- Photography and portfolio use — whether you may photograph and publish the setup.
When to use it
Send the contract once the client has accepted your event planning proposal and before you place a single hold with a venue or vendor. A venue hold made on a handshake is the classic way planners end up out of pocket.
It fits conferences, product launches, galas, milestone birthdays, private parties and corporate offsites. For weddings it works as written, but pair it with the wedding planning questionnaire so the details about family, traditions and vendors already booked are on paper. If you are only supplying one service, such as decor hire or a single on-site staff member for an evening, a short service contract is less work for both of you.
Clauses event planners can't skip
Guest-count lock date. Catering, rentals and seating are all priced per head. Set a date (often 10-21 days before the event) after which the client can increase the count only at the vendors' late-change rates, and can't reduce it at all. Put the date in the contract, not in an email.
Vendor contracting. The cleanest setup is that the client signs and pays every vendor directly, and you coordinate them. If you contract a vendor in your own name, say that the client must pay you the vendor cost before you commit, and that vendor cancellation terms pass through to the client.
Commission disclosure. If a florist pays you 10% for referrals, write it down. Many planners choose to pass those discounts to the client or decline them entirely, which is also worth saying.
Event-day hours and overtime. Coordinators lose the most money here. Define on-site hours (for example 10 hours including setup), the number of staff, an hourly overtime rate per person, and a hot meal and break for your team if the day runs past six hours.
Weather and backup plans. For outdoor events, say who decides on the backup plan, by when, and who pays for a marquee or venue change. You coordinate the backup; the client funds it.
How to structure the planning fee
There are three common models. A flat fee suits most private events and is easiest to sell. A percentage of the total event budget, often 10-20%, suits corporate events where the budget is set in advance, but it needs a minimum fee so a budget cut doesn't cut your pay. Hourly works for consultations and small partial-planning jobs, but cap it or estimate it in the contract so the client isn't surprised.
Whatever the model, split payment into a non-refundable retainer on signing, an optional mid-point payment, and a final balance due before the event. Whichever model you pick, state it in one sentence the client can repeat back to you.
Customize it in your COLO workspace
Save this agreement as a contract template in COLO Contracts and reuse it for every event. Your client reviews and signs in the client portal with a typed name or a signature image, you add your company signature, and the signed PDF stays with the event's project.
Set the event up as a project with tasks for each vendor and deadline, and use invoices with partial payments for the deposit, mid-point and balance. Clients can pay by card or PayPal from the portal.
Common mistakes
- No lock date. Without one, guest counts and menus change up to the night before and the extra cost lands on you.
- Promising vendor outcomes. Write that you select and coordinate vendors with reasonable care, not that you guarantee their performance.
- Balance due after the event. Once the party is over, payment urgency disappears. Collect before the date.
- One cancellation rule for everything. A tiered schedule (for example, retainer only if more than 90 days out, 50% of the fee between 30 and 90 days, 100% inside 30 days) is fairer and easier to enforce.
- Ignoring your team's welfare. A 14-hour event day with no meal clause is a fast way to lose good assistants.
FAQ
Q: What should an event planning contract include?
At minimum: the event date and venue, the services you provide, your fee and payment schedule, who signs vendor contracts, a guest-count lock date, event-day hours and overtime, cancellation and postponement terms, and a limit on your liability for vendor failures.
Q: Should vendor contracts be in my name or the client's name?
In most cases the client should sign vendor contracts directly. That keeps the client liable for vendor payments and keeps you out of the middle if a vendor fails. If you do contract vendors yourself, collect the money first and say so in the contract.
Q: How much deposit do event planners usually take?
Many planners take 25-50% of their planning fee on signing, with the balance due two to four weeks before the event. Collect the final balance before the event date, never after.
Q: What happens if the client postpones the event?
Treat postponement separately from cancellation. A common approach is one free date change if requested more than a set number of days out and if you are available on the new date, with fees already paid carried over and a rebooking fee after that.
Q: Do I need to disclose vendor commissions?
Yes. If you receive referral fees or commissions from vendors, say so in the contract. Undisclosed commissions damage trust quickly when a client finds out, and some clients will treat them as a conflict of interest.
