Add this to reach free shipping
Revenue isn't lost at checkout. It's lost in the cart.
It's 9 PM. You check the dashboard. Average order value: $43. Your free shipping threshold: $50. The gap between those two numbers has been open every single day this month. That's not a bad day. That's a system that doesn't know it's failing.
The invisible gap
Most merchants set a free shipping threshold and never revisit it. Your AOV moves. Your threshold doesn't. The gap compounds quietly.
The feeling something's off
You've optimised your ads. Improved your product pages. The traffic is there. But the revenue per order stays stubbornly flat. You know something isn't converting — you just can't see it.
You've earned a better cart
Merchants who build good stores and work this hard deserve a cart drawer that earns its place. One that reads the basket, closes the gap, and does the work while you sleep.
We've spent months inside Shopify dashboards like yours. We know what the numbers look like when the cart isn't doing its job.
We didn't build CartBoost because it sounded like a good idea. We built it because we watched store after store leave the same money on the table — a percentage point here, a few dollars per order there — until the compounding silence became undeniable.

Latch
Your cart starts closing the gap tonight.
Every shopper who opens the cart sees their progress toward free shipping and a product recommendation chosen specifically to close their gap. The recommendation isn't random — it's matched to what's already in their basket.
What Monday morning looks like.
It's 6:47 AM. You open Shopify before the day starts.
Average order value: $61. It was $43 four weeks ago.
Free shipping threshold: $55. CartBoost closed the gap 1,247 times last week. It recommended a product. The customer added it. The order crossed the line.
You didn't change your ads. You didn't renegotiate with suppliers. You changed what happens in the cart.
That's what CartBoost is for.
"Every visitor who leaves below your threshold is leaving revenue you've already paid for — through ads, SEO, and fulfilment. The gap is invisible. The cost is compounding."
CartBoost makes the gap visible. Then it closes it.
