Alternative Checkout Method for Shopify?

Question

Is there a way to redirect the "Proceed to Checkout" button in the Shopify cart to another system to process the sale? The fact that developers/designers have no access whatsoever to this last part of the sales process means that even the slightest change becomes an unsurmountable problem. Does anyone know if it would be possible to replace this last stage with another system?

Answer 1

The checkout flow is hosted to allow for PCI compliance via Shopify. Shopify uses a single domain for processing the checkouts on checkout.shopify.com because of this it is not possible to customize a single checkout page, only the css. There is however a method to the madness. PCI compliance is a requirement for most payment gateway interfacing software and quarterly audits are usually required. If Shopify allowed these steps to be changed it would likely break their PCI compliance and cause all sorts of issues.

I don't think this was a design mistake but rather a trade off to have the best of both worlds.
