Shopify Checkout Extensibility Upgrade FAQs
What happens if I don’t upgrade?
Old customizations stop working as Shopify retires them, which can break tracking, offers or discount logic at checkout.
Can you keep our checkout looking the same?
Mostly, yes. Checkout Extensibility supports branding, custom fields and upsells through supported extensions, and we rebuild what you rely on.
Should I use Shopify or a custom ecommerce site?
Shopify is a great fit for most standard retail stores. Custom ecommerce makes sense when you have complex pricing, B2B ordering, configurable products or logistics that off-the-shelf platforms fight against. We build both and will tell you honestly which fits.
Can you move my products from my old store?
Yes. We migrate products, images, customers and order history, clean up product data and set up redirects so you keep your Google rankings.
