Is CAPTCHA blocking legit buyers at checkout and killing conversion?

Question

I'm experiencing a frustrating issue where our online store's CAPTCHA system seems to be creating more problems than solutions. Legitimate customers are struggling to complete purchases, getting stuck or completely abandoning their cart due to complex verification challenges. We've noticed a significant drop in conversion rates, and I suspect our well-intentioned security measures are actually driving potential buyers away. How can we balance robust bot protection with a smooth, user-friendly checkout experience that doesn't compromise our sales performance?

Is CAPTCHA Worth the Conversion Trade-Off for My Shopify Store?
CAPTCHA protects against bot-driven coupon abuse, account farming, and scraping - but visible challenges (image grids, puzzles) add real friction to genuine checkout. The key is using the least-disruptive form of protection that still catches bad actors.

Avoid
    Visible puzzle CAPTCHA at checkout
    Adds 15-30 second delay. Fails often on mobile. Kills conversion for mobile buyers.

Consider
    Invisible reCAPTCHA v3
    Scores sessions in background. Only challenges suspicious ones. No user friction for most buyers.

Growth Suite Tip
  Growth Suite's Offer Fatigue Prevention and server-side code enforcement removes the need for CAPTCHA on discount flows. Because codes are tied to individual sessions and deleted server-side when they expire, bot-scraped codes are already dead by the time they're shared - no puzzle challenge needed.
