NotifyStock vs The Competition
Where NotifyStock is designed to be clearer for merchants
What The Experience Is Built Around
"Every core workflow should stay inside Shopify admin so merchants do not need a second external login to configure the app."
Every "Sold Out" Costs You Real Money
Without a capture flow, sold-out product traffic leaves without giving the merchant a follow-up path.
