Why Ringly.io is a Better Choice

Best for Shopify stores looking for the best way to offer 24/7 AI phone support at a fraction of the cost.

How it went when I tried setting up Ringly:

After I installed the Shopify app, the only thing I had to do was to upload my data to the knowledge base. (website was uploaded automatically)

After I did that, I could already speak to my agent via a web call.

Setting it live was as simple as picking a phone number with my area code from the dashboard. I was able to connect the number with 1 click. (The number is also free and included)

There was not really anything else to the setup.

They claim that out of the box, their agents resolve an average of 73% of support calls. They back that up with data from over 2,100 active Shopify stores.

Signup -> onboarded took only 4 minutes and 12 seconds. Most of that time was spent waiting for the knowledge to be uploaded.

Over the first 2 weeks I used it (14-day free trial), it resolved 76% of my calls on its own.

The rest of the calls were escalated to a support ticket by my agent.

(update: the more calls you get, the smarter it gets. As of today, my resolution rate is 79%.)

Standout Features (pros):

  • Very easy setup (almost none)
  • Pay on results pricing

Pricing is on a results basis; you don't pay until your agent has at least a 60% resolution rate

Shopify integration is native. It will allow your agent to solve order status and refund requests on the phone.

Reviews are overall very positive, mainly because of the results-based pricing. If you don't pay unless you get results, every customer gets results.

Cons:

  • Phone support only

What’s unique about Ringly is that it is the first AI phone support tool built for Shopify.

Editors note: Ringly.io opened 5 spots for Shopify stores to pay $0 until AI resolves 60% of your support calls. You can book a call to claim it.

Final Thoughts

Here’s a quick recap to help you make the right call:

  • Vapi is best for technical teams and large enterprises looking to go deep on customization, scale to millions of concurrent calls, and control every aspect of voice AI infrastructure.
  • Retell shines for smaller businesses and contact centers that need a dependable voice agent with core features like transcription, basic automation, and easy CRM integrations, without overwhelming complexity.
  • Ringly.io is the ideal choice for Shopify brands

While all platforms have their strengths, Ringly.io quietly delivers the best of both worlds: the power and scalability of platforms like Vapi, paired with the ease of use and business focus that Retell aims for. It’s the only solution that truly understands the needs of modern, growing brands—and meets them without added friction.

So whether you're a scrappy startup recovering abandoned carts or a scaling DTC brand optimizing support, Ringly.io gives you everything you need out of the box—no dev team, no delays, no overheard tech talk. Just results.
