Your organizations would need to open an account with one of these payment processors (if you don't have one already) and authorize Auctria to process charges through your payment processing account.
The transactions are happening between your Organization and your bidders, Auctria is only facilitating them.
An Organization can only be connected to a single payment processor account at a time, either Stripe or Authorize.Net
Auctria And Stripe
Stripe is a tier-1 payment processor that handles all functions for secure transmission and storage of credit card information. Though the credit card information is entered in Auctria, no credit card payments, or funds, are processed by Auctria. All credit card payment processing flows through your Stripe account.
If you don't already have a Stripe account, it only takes a few minutes to complete the sign-up process online at stripe.com. To fully establish a link with Stripe, you'll need to input your bank account information to allocate where to deposit the funds. After completing the Stripe setup, you will be able to connect Auctria to your Stripe account so you can process credit card payments for your Auctria auction charges through your Stripe account.
Stripe handles all credit card payment funds. Auctria is not a part of the financial transaction with your bank. After settlement, and transit time (about 2-5 business days after the payment date), Stripe will transfer the funds to your bank account minus the credit card processing fees. See Credit Card Costs for more details on the fees involved.
Auctria And Authorize.Net
An Authorize.Net account can be set up as a gateway to a wide variety of existing merchant accounts. If you have an existing merchant account, you can ask them if they support Authorize.Net. Please be aware, there are fees associated with a gateway account like this.
When using Authorize.Net as a gateway account, the charge is processed by your existing merchant account. You would pay the fees that apply to those transactions (we do not know and have no control over what those fees are). See Credit Card Costs for more details.
Auctria And Credit Card Readers
Auctria provides support for some USB Credit Card Readers allowing for faster, more accurate data entry of credit card numbers (only). These devices are generally not the same as, or function like, "readers" provided by services such as Square or similar "Point-of-Sale" services.
