Dwolla allows you to send and receive payments, much like PayPal. They work with all US banks and credit unions.
They offer payment API and easy integration with other useful platforms, such as QuickBooks, Plaid, or Slack.
Moreover, Dwolla features account-to-account transfers, next day or same-day ACH transactions, wire, push-to-debit and real time payments.
All in all, they look like they’re down to business.
