The Problem
Checkout experience complexity:
Competitor Landscape
- Rebuy (smart cart)
- CartHook
- Checkout Blocks (Plus)
- Quick Order apps (partial overlap)

Analytics on drop-offs and path selection
⚠️ Potential Challenges

- Handling very large line counts within API and checkout limits
- Discount code and stackability edge cases
Risk Level: Low
🎯 Keys to Success
- Higher checkout completion rates for B2B carts
