On-site checkout vs "external" checkout
I have an small online store, built using Shopify. I've set it up all right, but because of my location,
I can't use Stripe, Authorize.net or any other popular payment gateways, which offer "on-site checkout", meaning a user stays on the same page during the entire checkout process.
The two alternatives are:
- Use another payment gateway, which will redirect the users to another web page, where they can enter their credit cards data and checkout. The problem is that this page can't be customized more than just logo and colors.
- Use PayPal Express Checkout, which gives the option to create a guest account and fill the data of your credit card. The problem is that it's a button that says Create an account and I'm pretty sure this will scare away buyers (they're required to "sign up" at the end of a purchase).
I couldn't find any data on which scenario has a higher conversion rate. Does anyone have experience with such issues and could share some helpful knowledge about what solution is better?
