Your PTO just pulled off an incredible silent auction. Volunteers spent weeks soliciting donations, designing bid sheets, and promoting the event. You raised $10,000 for new playground equipment. Then the invoice arrives from your auction platform: $300 to $800, depending on the percentage they charge.
That money was supposed to go to the kids.
The hidden math of percentage-based platforms
Most online auction tools charge between 3% and 8% of gross auction revenue. Some bury additional fees for payment processing, text notifications, or "premium" features like bid tracking. Here is what that looks like at different fundraising levels:
- $5,000 raised at 5% = $250 in platform fees
- $10,000 raised at 5% = $500 in platform fees
- $25,000 raised at 5% = $1,250 in platform fees
The more successful your event, the more you pay. That is a strange incentive structure for a tool that is supposed to help nonprofits.
Why flat pricing makes more sense for schools
A flat fee means you know your cost before the event starts. Whether you raise $2,000 or $20,000, the platform cost stays the same. Every additional dollar goes directly to your cause.
This matters especially for PTOs and small nonprofits where budgets are tight and every expense needs to be justified to a board or a room full of parents. Telling your community that you spent $700 on software to run a fundraiser is a hard conversation. Telling them you spent a predictable flat fee is much easier.
What you actually need from auction software
Most PTOs running their first or second auction need a short list of things:
- A way for bidders to place bids from their phones
- Real-time updates so people know when they have been outbid
- A clean close process that tells winners what they owe
- An item list they can set up without a training session
You do not need a payment processor built into the platform. Most school auctions collect payment at a checkout table with Venmo, cash, or a check. Paying extra for integrated payment processing you will not use is wasteful.
A real example
A PTO in the Midwest ran a spring auction with 45 items and 80 bidders. They raised just over $8,000. On a platform charging 5%, they would have paid $400 in fees. On a platform charging 8% plus a payment processing fee, they would have paid closer to $700.
With a flat-fee tool like MyGiveKit, that $400 to $700 stays in the fund. Over two or three events per year, the savings add up to real money — money that buys books, funds field trips, or covers teacher appreciation gifts.
The bottom line
If your PTO is evaluating auction software, ask one question first: does this platform charge us more when we succeed? If the answer is yes, keep looking. Your volunteers worked too hard for a percentage of their effort to go to a software company.
MyGiveKit charges a flat fee with no percentage of bids raised. You can set up your event, add items, and preview the full bidder experience for free before you pay anything.
