The cart that follows shoppers around your store

Most drawers open on add-to-cart and close. Boost's stays on screen while shoppers browse and shows the next discount before they've earned it. Shopify's built-in tiered discount applies once every eligible item is already in the cart. Same 20%. Different moment.

Chomps ran 15% at $30, 20% at $50, 25% at $70. Jones Road, on its first sitewide sale ever, chose a ladder. Brightland showed the rungs inside the cart drawer. They built it by hand. Boost puts it in the cart, on every page, while shoppers decide.

Boost edits no theme file. The cart runs on top of your theme and matches your colors. Boost cannot fix a Shopify outage, and we say so.

Your numbers, by bags or by dollars, and the date the sale ends. A coach runs the profit math with you. That's the whole job.

Nothing. On Cyber Monday 2025, Shopify's admin went down and founders couldn't switch their sales on. Set Boost on Wednesday night. Sales Mode ends the sale on your date. You touch nothing.

Mostly discount logic, not outages. Of 25 incidents founders logged over six years, 23 were codes blocking tiers, a free gift that didn't add at the threshold, free shipping that wouldn't combine. Boost applies the discount itself at every rung, no codes to stack, nothing to break at checkout.

Good. One tap in the Boost cart turns an order into a subscription through the app you have. Every email captured in the cart hands to Klaviyo before checkout.

Real fear. Jones Road's board asked it. The founders who solved it never discounted the product on its own page. They put the deal on the bigger order, the bundle, or a gift for the biggest carts. Full price never moves. That's the whole idea behind Boost's cart.

Both camps are right. About half of Black Friday purchases are repeat buyers; new customers acquired that weekend come back 4 to 22% of the time. Black Friday is a stock-up event for your regulars and a poor acquisition event. Plan it for the people who already buy from you. Boost's one-tap subscribe is for the few new ones worth keeping.

Model profit per scenario before you pick. One founder's math: 15% off a $100 product cuts margin from 20% to 5%, so you need 4x the volume to make the same money. Raise the minimum before you deepen the percent. The founders who report "most profitable day ever" ran bundles or a gift at a threshold. The ones who report "cool $320k day, not all profit" ran sitewide.

Nobody pauses. They cut Meta hard and lean on the list, and revenue holds. Pai Skincare 2025: spend down 65%, revenue flat. Boost doesn't touch ads. It makes every visit you already paid for worth more.
