11 Mistakes to avoid during fundraising events

The most expensive fundraising event mistakes rarely look like mistakes at first.

A venue that costs a little more. A ticket price based on what other nonprofits charge. A donation appeal saved for the final five minutes. A checkout process with one extra step. 

Each decision can seem harmless, yet together they can shrink net revenue, frustrate guests, and leave a team wondering why a busy event raised less than expected.

That matters because fundraising events are still delivering strong results. 77% of nonprofits met or exceeded their 2025 event fundraising goals.

The opportunity is there. The challenge is avoiding the decisions that quietly work against it.

Below are 11 fundraising event mistakes that can cost nonprofits money, donors, and momentum, plus practical fixes to catch them before they show up in your final numbers.

Mistakes to avoid before your fundraising event

1. Planning before setting a clear fundraising goal

First set a realistic target and work backwards. Without this, tasks lack purpose. 

Remember, “no goal – or worse, a vague one” is a very common mistake. A strong goal should be tied to a need (e.g., “raise $20,000 to fund 100 scholarships”). 

Current event-planning guidance recommends beginning 6–12 months ahead for major nonprofit events. A clear goal tells your team what that planning time needs to accomplish. 

2. Budgeting around gross revenue instead of net revenue

Always budget for net profit, not just ticket sales. For example, one budget guide points out that an event raising $100K with $70K in costs nets less than an event raising $70K at $25K costs. 

In other words, high ticket sales mean little if costs explode. Include all fees (venue, food, AV, processing) in your budget. 

Aim for at least a 2:1 or 3:1 return – meaning 2–3 raised for every $1 spent. If you plan a net target (say $30K), estimate expenses and set your gross goals accordingly.

3. Starting sponsorship and ticket sales too late

Sponsors need time for budget approval, branding materials, and guest lists. Attendees also need repeated reminders. 

Begin promotions early. Experts recommend crafting your timeline 4–6 months out. In practice, start reaching out to sponsors and open ticket sales well in advance so donors have time to commit. 

For instance, one event guide advises opening ticket sales immediately and marketing in waves. This gives awareness time to build; if you wait until a few weeks before, you’ll struggle to sell out or find sponsors.

4. Pricing tickets and sponsorships without knowing your audience

Set prices based on the audience you’re trying to attract. A high-end gala with wealthy donors can charge more, but a community event should keep tickets affordable. 

Start with expected attendance, event costs, past purchase behavior, donor capacity, and comparable events. 

Ticket price (too high) can block participation; too low and you leave money on the table.

5. Building the event around entertainment instead of the mission

Don’t make the fun the focus. One seasoned fundraiser notes, “the biggest mistake... is building the whole event around entertainment and leaving the ask vague”. 

Guests may enjoy the show but still leave empty-handed if they never hear a clear message of why to give. Always frame entertainment around your mission. 

For example, plan a short, compelling speech or video about your impact before leading into donations. Keep reminding attendees what their gifts will do, and make your main fundraising pitch central to the program.

6. Making the main fundraising ask vague or poorly timed

“Please support us” is not a fundraising strategy.

State what you need, why you need it, and what different gift amounts can accomplish. Place the appeal after a strong mission moment and before guests become tired or begin leaving.

BetterWorld suggests briefing table captains on “when the paddle raise or pledge moment happens” so everyone is ready. 

7. Letting the program run too long

Keep events tight. Long-winded speeches or filler activities sap energy. As one fundraising advisor observes, “letting the program run too long... lowers energy and reduces donation momentum”. 

Aim for a concise agenda. Mix in entertainment or breaks to reset the crowd. Use timers if needed. Remember: it’s better to end slightly early on a high note than to drag on and watch attention fade.

8. Using separate systems for ticketing, auctions, paddle raises, and check-in

Juggling multiple tools creates chaos. For example, many nonprofits end up “exporting spreadsheets and piecing together reports by hand” when they use different platforms for each task. 

It slows down check-in and can lead to errors. Instead, use one integrated event platform so attendee info, bids, and donations all live in one place. That way you spend less time on admin and more on fundraising.

9. Failing to test check-in, payments, and checkout before guests arrive

Rehearse everything. Test your tech before event day. Run a full rehearsal. Test check-in tablets. Payment processors. Auction software. Make sure WiFi is strong. 

Pre-testing devices (tablets, scanners, card readers) and the network is critical to avoid delays and technical glitches.

Have extra devices and chargers on hand. By ensuring everything works smoothly (and backup plans are ready), you prevent headaches at the door and keep the experience positive.

10. Failing to plan auctions, raffles, and paddle raises into the event

Don’t forget to add auctions, raffles, and other fundraising strategies into your event. These are major revenue drivers. 

Auctions can be especially valuable when matched to the audience. In 2025, 77% of nonprofit professionals reported stable or growing auction revenue.

Put your paddle raise “before your final few items” so donors without auction winnings can still give. In short, don’t skip or improvise these elements – schedule them for maximum impact.

Check state and local laws before operating raffles or other regulated games of chance.

11. Treating checkout as the end of the donor relationship

The work continues after the final bid. Begin stewardship immediately. The speed and style of your follow-up can make or break future support. 

Research shows donors who are thanked within two days are far more likely to give again. 

So send thank-you emails right away and follow up with personal notes or calls for major donors. Showing prompt gratitude turns a one-time check-out into a lasting partnership.

FAQs

1. What is the most common fundraising event mistake?

Often it’s not setting a clear goal. Experts agree that jumping into planning without a specific target is a major pitfall. Without a goal like “raise $X for Y,” your team has no benchmark and may waste effort.

2. How do you set a realistic fundraising event goal?

Review past event results, likely attendance, donor capacity, sponsorship potential, ticket revenue, and other fundraising streams. Subtract projected expenses to determine the net amount your nonprofit can realistically raise.

3. How much should a nonprofit spend on a fundraising event?

Keep expenses relatively low – ideally no more than about 25–35% of total revenue. Event expenses should stay below roughly 35% of gross revenue (25% is even better). This aligns with the rule of thumb that you should raise 2–3 times what you spend.

4. How can nonprofits increase net revenue from an event?

Diversify income and control costs. Use multiple channels (ticket sales, auction, raffle, sponsorships, matching gifts), so you’re not relying on one source.

5. When should the main fundraising ask happen during an event?

Place it after guests have seen clear evidence of the mission and before attention drops. Avoid putting the main appeal at the very end, when guests may already be preparing to leave.
