Questions.
Isn't Checkify just a checkout builder?+
Yes, and a decent one. The difference is what Sling adds around the checkout: Subscribe & Save, server-side pixels and automatic Shopify order sync, at a flat 0.5% per order software fee.
Who processes the payment?+
Your own connected Whop account, under Whop's terms. Sling is checkout-builder software and never holds or touches your customers' funds.
What does it cost?+
$99/mo plus a flat 0.5% per order. These are software fees billed by Sling to the merchant, on top of your own Whop account's card processing.
