Credit Card Fees Comparison

Silent Auction Pro™ partners with Vantiv Integrated Payments (now Worldpay) and PayPal - industry leaders in PCI DSS compliant payment processing, to offer fully-integrated, secure and cost-effective payment processing. The best processor solution depends on the size of your event, the type of cards your guests use, your organization's charitable status and if you already have a account with one of our partners. The table below outlines the various fees in a side-by-side comparison.

Processing Fees
Fee Vantiv PayPal (Non-501c3) PayPal (501c3)
Processing Fee (card present, non American Expresss) 2%-3.5% (1)(2) 2.9%(2) 2.2%(2)(3)
Processing Fee (American Expresss) 2.89% (2)(4) 3.5%(4) 3.5%(4)
Per Transaction Fee (all card types) $0.25 $0.30 $0.30
Min Monthly Fee (5) $35 n/a n/a
Master Card Monthly Fee $2.50 n/a n/a
Reader Rental $35/reader (6) n/a (7) n/a (7)
(1) Vantiv charges 1% over the Interchange rate charged by the credit card companies. The rate you would pay will depend on the type of card your customer uses and will typically range from 2.5% to 3.5%. Standard bank cards will be at the lower end while high rewards type cards will be at the upper end.
(2) The lowest rates (those quoted above) are for "card present" transactions where the credit card is immediately charged. Transactions using stored credit cards are a bit more expensive as they involve more risk for the processor. In general we recommend using stored cards during check-out as that speeds up the check-out process and keeps your attendees happy. On average, stored cards at PayPal will process at or around the Non-501c3 rate of 2.9%. Please see a full description of merchant fees at
(3) To receive the non-profit rate you must complete PayPal's non-profit application and be approved.
(4) American Express cards process at a higher rate than all other cards. Also, American Express usually requires a separate approval process when you apply for a merchant account (either PayPal or Vantiv).
(5) Minimum monthly fee applies only to those months where there are transactions.
(6) For added security, Vantiv requires encrypted credit card readers. You may purchase these directly from Vantiv for ~$100 or rent them from Silent Auction Pro for $35 per reader for your event.
(7) PayPal uses unencrypted readers that can be purchased for less than $20. For more info, see our Credit Card Readers help page.
  1. To receive the PayPal 501c3 rate you must complete the PayPal application at
  2. PayPal supplied mobile chip/card readers will NOT work within Silent Auction Pro. You MUST have a corded USB card reader. Please see our Credit Card Readers help page.

To rent credit card readers/swipers for Vantiv accounts:

Silent Auction Pro offers credit card reader rentals for Vantiv customers. These readers are USB based plug-and-play units that require no additional software and are specific to groups using Vantiv's integrated solution. Rental fees are $35.00/reader and should be reserved at least a month ahead of your event. To determine how many stations (readers, computers, printers) you will need to streamline check-out, see the table below. At minimum, two are recommended to have one as a back-up.

You must be a Group Administrator level member to request credit card readers. Reserve your credit card readers by completing the Credit Card Reader Request Form. Mouse over the Group Admin menu item and click Request Credit Card Readers. The form contains the following fields:

After verifying your information, click Generate Contract to view the card reader contract. Review the contract, scroll to the bottom, check the "I agree..." checkbox then click the Send Reader Request button. This will email your card reader request to our Customer Service department and they will respond with a confirmation email and credit card receipt within 24 hrs. A confirmation of the request will also be sent to the email address you provided.

A few notes about credit card processing, associated fees, and supported credit cards

While you can process credit cards through Silent Auction Pro using a different payment vendor certain functionality is disabled, such as support for online ticket sales, online bidding, and express check-out (placing cards on file). See the FAQ topic, Can I use my own credit card processing company?.

Any type of credit card can be processed through Silent Auction Pro depending upon the arrangements a group makes with your processor choice, however, rates vary. These rates are not set by Silent Auction Pro.

Refer to the Event Fields table in the Events help topic for more on custom messages.

Signatures are not required for credit card purchases though having a signature helps should a payer dispute a charge. Billing address need not be provided.
