About Facebook 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 a certain format. It automatically reads in your variants like size and color, and presents them as options for your shoppers to choose. It's similar to how you might ask a store associate for your size and color in a brick-and-mortar store!

We auto-generate a Shopify checkout link with all the items your buyers commented for. And it will even handle waitlists for items that are out of stock, and it will automatically message the waitlist when it's back in stock.

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 a complete game changer for our business. We had previously tried to hire a development firm to make a custom app for us to do what this app does. Our Facebook live sales generate thousands of sales, and it's nearly impossible to manually go through the comments to invoice everyone. It used to be complete chaos going through comments on our livestream and creating draft orders to send out. With this app, we can focus on selling during our livesale and the software does all the tedious work of creating and sending out invoices, and following up to remind them if they didn't purchase. We have very loyal and competitive shoppers that love our brand and merchandise. Our items often sell out. Having an app figure out who commented first and tracking inventory to keep a waitlist is crucial for us to scale our business. We do 2-3 live sales a week now. And livestream shopping is now a large part of our business.

As someone who was desperate to add CS to our lives, but with it not being available in Canada, this is 10000% a godsend of an app. I switched briefly to another app that seemed to offer “more for less” but I did not have the freedom of posting what I wanted like i do with this app and thus it was not a good fit at all. This really is the easiest, least cumbersome, straightforward, but super cool comment selling app I’ve seen or tried yet. I won’t be leaving again!


I redownloaded this app a few days before my life and it worked effortlessly. I was happy to see my update suggestions were implemented. This was foreign to my customers but they caught on quickly.

Joe is extremely hands on and helpful with assisting you with any issues.

I highly recommend this app.
