Frequently Asked Questions

What if you cannot fix it?

For the paid audit and implementation scope, if I cannot validate the agreed technical fix within 48 hours, you get a full refund.

Do I need to share passwords?

No. You add my email as a collaborator or restricted user in Shopify/Google. Access is revocable anytime and I do not access payment settings.

What is not included in the $199 package?

The $199 package covers one agreed technical implementation (GTM, DNS, Liquid/JS fix). It does not include legal drafting or ad campaign management.
