What does checkout work cost?

Projects start from $3,500, depending on the number of extensions, Functions and tracking changes. We send a fixed-price quote within 24 hours.

Will our analytics still work?

We migrate tracking to Shopify's Customer Events and web pixels and verify every conversion event before launch.

Is it risky to change checkout?

We build and test in a development store, then launch in checkout editor steps that can be rolled back instantly.
