Add “dropship/affiliate product” support in Stores/Payments. Let a product be marked as dropship and include an external purchase URL.

When enabled, the Add to Cart/Buy buttons should redirect to that external link instead of HighLevel’s internal cart/checkout.

Reason: the merchant doesn’t hold inventory; today they’re forced into internal checkout or to build separate pages with manual buttons—cumbersome and not attached to the store. This blocks many dropship/affiliate use cases (e.g., skincare, clothing).
