Stripe Payment Gateway
Stripe is our personal favorite. It is a free plugin; you just pay to have it configured when you work with a professional. Even technologically challenged clients are able to navigate the Stripe dashboard and it is similar to PayPal in terms of fees.
When you choose Stripe, your developer will need you to provide both TEST and LIVE keys. No matter what payment processor you choose for your store, you will be required to set up an account and manage the money moving in and out of it.
Strip accepts a wide array of payment options. Please speak with a developer regarding the Strip integrations or visit their website for more information.
