FAQ
Will these custom features work with Shopify Online Store 2.0?
Yes! All custom code and sections are built natively for Shopify OS 2.0, allowing you to add, reorder, and edit content directly within the Shopify Theme Editor without editing code.
Why should I choose custom code over installing a Shopify App?
Custom code eliminates monthly subscription fees, prevents theme bloat, loads significantly faster, and gives you 100% control over design and functionality.
How do you access my store to work on the code?
I request secure Collaborator Access through my official Shopify Partner account. You never need to share your admin password.

Juan did an excellent job on our bundle pricing feature. 👏 We tested it today, and after making one small Shopify shipping setting adjustment on our end, everything is working perfectly. The bundle flow looks great, and we're really happy with how it turned out. Highly recommend Juan for anything Shopify related. Solid 5 Stars!
