Thanks for reaching out to us about this. I’d love to help recommend an app for your store that can speed up the checkout process.
One free app that offers this is Fast Checkout in One Click. Skip Cart Add to Cart Button and Instant Buy are two other options that have free plans and offer the same functionality. All of these apps help speed up the checkout process by removing the cart page, and directing customers directly to the checkout instead.
Can you tell me a bit more about the logo that you want to appear on the side of your cart/checkout? If you have a screenshot or an example of how you would like this to look, post it in the thread and I’ll be happy to help.
Looking forward to hearing from you!
This is Song Fei from Giraffly which develops apps for Shopify store owners. And glad to found you're looking for an app for quick checkout.
The quick checkout experience is important for conversation rate. Our app is : Sticky Add to Cart + Animation
The "Add to Cart" button can set to skip the cart and go directly to the checkout page. Reduce cart abandonment rate and make your customers complete their purchase right away.
And this app has a lot more function. You can see more instuction here:Sticky Add to Cart + Animation. You'll love it.
