Auction software built for nonprofits.
Raise more from every donated item without adding work for a small team. Supporters bid from their phones, winners pay automatically, and the money lands in your own Stripe account.
What gets easier.
The parts of auction season that take the most volunteer hours.
Small teams, big events
Your staff is already running the event. Item entry, bidder updates and checkout shouldn’t need three more people.
Money left on the table
Paper auctions end when the room empties. Online bidding and outbid texts keep the competition going until the close.
Messy settlement
Matching bid sheets to payments takes days. CausIO builds invoices, charges cards on file and tracks who has paid.
Built in.

Questions, answered.
How much does CausIO cost?
Qualified nonprofits have no monthly plan: they pay a $200 entry fee and 5% of what each auction raises, or one yearly price with no platform fee. Other organizations pick a plan from $49 a month plus a 1.5% to 3% platform fee. Stripe’s standard processing fees apply, and funds go straight to your own Stripe account.
Who holds the money?
You do. Payments are made on your own connected Stripe account, so funds go straight to your nonprofit.
Do bidders need to download an app?
No. Bidders open a link or scan a QR code and bid in their phone’s browser. They sign in with a one-time email link, so there is no password to forget. They can also bid by text message.
Can we record each item’s fair market value?
Yes. Record a value for every item, and choose item by item whether bidders can see it in the catalog. Values also print on item certificates.
Run your best auction yet.
Nonprofits pay as they go, or once a year with no platform fee.
