About FB Comment Selling

Live stream shopping is here. And Facebook Comment Selling lets your boutique sell instantly and effortlessly to anyone who wants to buy from your live sale.

Invoices are created and sent to anyone who comments in the right format. It automatically reads in your variants like size and color, and presents them as options for your shoppers to choose. Or they can specify the variants in their comment.

We automatically generate a Shopify draft order and checkout link with all the items your buyers commented for. And it creates a waitlists for products that get sold out, and automatically messages everyone on the waitlist in order when they're available to purchase.

If you're familiar with livestream shopping apps like CommentSold and BuyitLive, this app is better because it is completely integrated into Shopify. No more forcing your shoppers to create an account, or syncing inventories between CS and Shopify. Everything is tied into your Shopify store, including your checkout process.

Comment selling gives your FB post a boost in the Facebook feed. The lift in comments shows Facebook that you have organic engagement, which gives your brand more chances to get discovered by your shoppers' friends.

The social aspect is powerful - seeing all these comments creates a sense of urgency in the buying process that leads to faster checkouts. When customers see the social proof, they know they have to comment quickly before your product is sold out.

They can keep commenting to add other items to their cart during your show. When your live sale is over, your customers check out once. And you can go to bed and wake up with paid invoices the next morning!

This app has been amazing for my business! Not only does it save me tons of time from manually invoicing, but it helps make sure my customers get the items they want before they sell out. The autobot feature is wonderful in that it gives the customer the options to choose sizing and color/variant without having to search for what sizes are available. The waitlist feature and auto reminder is great too. It definitely saves you from hunting down the customer for payment. Now that this has the group capability, it's so helpful! My girls are loving the ease of use and I am loving the time saved!! My favorite part of the app is that there is no need for your customer to register with another account or site. They simply click the "" link once, approve comment selling, and you're good to go from there on out. Definitely easier and more customer compliant than other systems! Thanks Joe and the Team! I can't wait to see what more fun features are in store in the future! Melissa at Modish Lily
