Customers

Why ecommerce leaders switched to Yuma

  • Before Yuma, we were drowning in a sea of over 10,000 tickets, and our first response time was a staggering 1 week. Other AI solutions we tried were unreliable, hallucinating, and didn't align with our guidelines.

  • We barely had to think about the technical side. Yuma just worked, right out of the box. That was a huge relief, so we could focus on customer experience rather than implementation.

FAQ

Frequently asked questions

Why do ecommerce brands switch from Sierra to Yuma AI?

Yuma is built for ecommerce. It works inside the helpdesk you already use, connects to Shopify, WooCommerce, Magento, Recharge, Skio and Loop out of the box, and you pay only for tickets it fully resolves. Brands like EvryJewels automate up to 89% of tickets, and most teams are live within a week.

Is Yuma a replacement for my helpdesk?

No. It works with the one you already use: Gorgias, Zendesk, Kustomer, and more.

How does Sierra's pricing compare to Yuma?

Sierra uses outcome-based pricing and does not publish rates; it says that in most cases unresolved or escalated conversations are not charged. Yuma charges only for fully resolved tickets. The price per resolution depends on your volume, and the median across customers is $0.74. There's no platform fee and no per-agent cost, and a 100% ROI guarantee backs it.

How long does it take to go live with Yuma?

Most brands are live within a week. Yuma installs inside your existing helpdesk and you can test it in a sandbox before it answers a single customer. The 30-day free pilot runs on your real tickets.

What if we're not on Shopify?

Yuma works wherever your helpdesk exposes order data: BigCommerce, Magento, WooCommerce, custom back-ends.

How do agents override AI replies?

Agents can edit or send drafts straight from the helpdesk; Yuma learns from corrections.

What is Yuma's Safety Guard, and does Sierra have an equivalent?

Safety Guard is Yuma's built-in hallucination prevention. It checks every reply for accuracy, policy compliance and confidence, and routes the ticket to a human with full context when something is off. Sierra says its agents come with built-in guardrails, and it runs simulations before changes go live.

Can I switch from Sierra to Yuma without changing my helpdesk?

Yes. Yuma installs inside Gorgias, Zendesk, Kustomer, Salesforce, Re:amaze, Gladly and more. Your ticket history, macros and routing stay where they are, and Yuma reads and writes through your helpdesk's API.
