Free Event Booking Proforma Invoice Template & Generator
An event proforma prices a date that is still on a tentative hold. It has to separate what the venue charges regardless of attendance, what scales with the guest count, and what is added on top as a service charge, then show the deposit that converts the hold into a booking and the balance the final invoice will carry once the guaranteed count is submitted. Every per-guest line on it is an estimate, and the document should say so.

Use-case checklist
What to include in a event booking proforma invoice
Two numbers cause most event billing fights and both are visible on this page. The first is the guest count. A proforma built on 140 estimated guests is not a bill for 140, and if the words estimated and guaranteed never appear, a final invoice for a guaranteed 152 reads as a price increase the customer never agreed to. The second is the service charge, which customers routinely read as gratuity and then reduce on their own, on a line worth nearly $2,900 here. Add a deposit taken to release a Saturday in October and a disputed final invoice is not just a receivable. It is a date you can no longer sell to anyone else.
- provider, customer, event, date, and venue
- package, guest count, rentals, and services
- deposit, service charge, tax, and expected total
- validity and booking or availability conditions
- contract dependency and preliminary status

How to make an event booking proforma invoice in 6 steps
Open the proforma invoice generator
Start from this page so the proforma invoice opens with fields and sample lines already set up for venues, event planners, and event-service providers. No account is needed to create or preview.
Enter both parties
Add your business name, address and contact details, then the customer name and address exactly as they should appear on the record.
Add the event booking lines
Replace each sample line with the real work or goods. Make sure the document shows provider, customer, event, date, and venue, package, guest count, rentals, and services, deposit, service charge, tax, and expected total.
Check the figures
Totals calculate as you type. Confirm quantities, rates, any tax line and the final total against your own records before you send anything.
Set the reference and dates
Give the proforma invoice a unique number and the correct date so it can be traced later and matched to related documents.

Worked example
A 140-guest awards dinner held on a tentative Saturday
Halloway Barn & Events issues a proforma to Castleton Dental Group on August 3, 2026 for an awards dinner on Saturday, October 24. The date is on a tentative hold, the guaranteed count is not due until October 14, and every per-guest line below is priced on the planner's estimate of 140.
- Venue rental, Great Barn and terrace, Sat Oct 24, 5:00 to 11:00 p.m., flat regardless of attendance
- $3,200.00
- Plated dinner, estimated 140 guests at $68.00 (guaranteed count due Oct 14)
- $9,520.00
- Four-hour bar package, estimated 140 guests at $26.00
- $3,640.00
- Chiavari chairs and linen upgrade (140 at $9.50) plus stage, podium and two wireless mics ($650.00)
- $1,980.00
- Subtotal
- $18,340.00
- Service charge, 22%, applied to food and beverage only ($13,160.00); this is a house charge, not gratuity
- $2,895.20
- Estimated sales tax, placeholder 8% on $21,235.20; which of these lines are taxable, and at what rate, differs by state and city
- $1,698.82
- Expected total on proforma PF-2026-0331, valid 14 days
- $22,934.02
- Deposit due to convert the tentative hold into a confirmed booking, flat per the booking agreement
- $5,000.00
- Expected balance on the final invoice after the guaranteed count, total less deposit received
- $17,934.02
Write the balance as "expected total less deposit received," never as a fixed $17,934.02, because the guaranteed count will move it. At 152 guests the dinner and bar lines alone add $1,128.00 before the service charge and tax recompute on top.
When this document is the right choice
Use this proforma invoice to show an expected transaction before a final invoice exists. A proforma invoice is a preliminary commercial document, not a final tax invoice or proof that payment is due. Replace it with the final invoice when the transaction is confirmed.
Frequently asked questions
The customer thinks the 22% service charge is the tip and wants to reduce it.
Say on the document what the charge is and what it is not. In the example it is a house service charge of $2,895.20 applied to the $13,160.00 of food and beverage, and it is not a gratuity distributed to staff unless your own policy says it is. Whether a mandatory service charge has to be disclosed a particular way, and how it interacts with tipped pay, varies by state and city, so have your attorney set the standing wording you put on every proforma.
The count dropped from 140 to 118 before the guarantee date. What actually changes?
Only the per-guest lines and everything calculated from them. Dinner falls to $8,024.00 and the bar to $3,068.00, the chair and linen portion drops by $209.00, while the $3,200.00 rental and the $650.00 AV do not move. The 22% then recomputes on the lower food and beverage figure and so does the tax. Check the booking agreement before you requote, because many venues set a floor below which the per-guest charge stops falling.
Is the $5,000 date-hold deposit refundable if they cancel in September?
That is decided by the booking agreement the customer signed, not by this proforma, and this document should reference it rather than restate it. A proforma that introduces "non-refundable" for the first time is weak ground for keeping five thousand dollars. Point to the clause by number, keep your cancellation schedule in the signed agreement, and have an attorney review that schedule before you apply it to a real cancellation.
Do I charge tax on the venue rental and on the service charge, or only on the food?
The example applies its labeled placeholder rate to the whole $21,235.20, rental and service charge included, purely so the arithmetic on the page can be checked. Real treatment is rarely that tidy: states differ on whether room rental is taxable, whether a mandatory service charge is taxable, and whether the answer changes when the charge is distributed to staff. Have your accountant confirm the treatment for your location, then build it into your standard proforma so the tax line stops being rewritten event by event.
Another client wants the same Saturday while this hold is still tentative. What happens to the first one?
Run it through whatever release procedure your booking agreement sets, and run it on a clock. Give Castleton a stated deadline to countersign and send the $5,000.00, tell them plainly that a second party has asked for October 24, and release the date if the deadline passes. What you should not do is carry a tentative Saturday in October for a month out of politeness. If the hold does lapse and they come back later, requote from scratch, because the 14-day validity on PF-2026-0331 is long gone by then and your per-guest prices for the season may have moved.
