SmartAlex vs VAPI for retail (2026)

​

The short version

• Pick SmartAlex if you want a working retail voice agent on your storefront and phone this week, with the CRM, order lookups, and win-back campaigns already wired in.
• Pick VAPI if you have engineers who want to assemble their own stack (swap speech-to-text, language model, and text-to-speech independently) and you are happy to bring your own CRM, campaign tooling, and billing.

​

Retail capability comparison

​

Four retail scenarios, side by side

​

Order status

• SmartAlex: the agent calls your order-status endpoint through a Custom HTTP Tool during the conversation, reads the tracking state back, and logs the contact in the built-in CRM. No glue code between the voice layer and your data.
• VAPI: you wire a function call to the same endpoint. Fully capable, but you own the server, the deployment, and anywhere you want that call logged afterward.

​

Returns and exchanges

• SmartAlex: the same Custom HTTP Tool pattern creates or checks a return, and you can gate a mid-call card action through the payments integration if a restocking fee applies. The interaction lands as a deal in the pipeline.
• VAPI: function calling handles the return logic; CRM, deal tracking, and any follow-up sequence are yours to build.

​

Store hours and stock checks

• SmartAlex: static answers live in the agent’s knowledge; dynamic answers (is this branch open now, is this SKU in stock) come from a Custom HTTP Tool. The storefront widget can resolve most of these in chat before a phone call is ever needed.
• VAPI: same idea, assembled in your app with your own frontend.

​

Win-back and abandoned carts

• SmartAlex: the Outbound Campaigns add-on schedules win-back calls, retries failed attempts, and tracks disposition, so a lapsed-customer list becomes a running campaign without extra tooling.
• VAPI: you build the dialer orchestration, scheduling, and retry logic yourself on top of the API.

How an order-status call flows on SmartAlex

​

Put the widget on your store

<!-- SmartAlex Widget -->
<script
  src="https://api.getsmartalex.com/storage/v1/object/public/widget-assets/smartalex-widget.js"
  data-tenant-id="YOUR_TENANT_ID"
  async>
</script>

import Script from 'next/script';

export default function StoreLayout({ children }) {
  return (
    <>
      {children}
      <Script
        src="https://api.getsmartalex.com/storage/v1/object/public/widget-assets/smartalex-widget.js"
        data-tenant-id="YOUR_TENANT_ID"
        strategy="afterInteractive"
      />
    </>
  );
}

• “Create a retail support agent that handles order status and returns.”
• “Give me the widget install snippet for my Shopify theme.”
• “Schedule a win-back campaign to everyone who has not ordered in 90 days.”

​

Integrations and honesty about what is live today

• Widget (the script tag above) for the storefront.
• MCP server for conversational control from an AI client.
• Custom HTTP Tools so the agent calls your commerce API mid-call. This is the live, load-bearing path for order status, returns, and stock checks. Part of the Power Tools add-on ($29/mo on Professional, included on Enterprise).

​

When VAPI is the better pick

• You have engineers who want to own the stack and swap speech, language, and voice components independently.
• You need a self-hosted or OpenAI-compatible custom language model endpoint, multi-agent squads, or unlimited low-level function calling.
• You want native mobile SDKs (iOS, Android, React Native, Flutter) embedded deep in your own app.
• You already have your own CRM, campaign engine, and billing, and you only need the voice layer.

​

Pricing at a glance

• Professional plan: $99/mo (250 included minutes, one number, one agent).
• Power Tools add-on: $29/mo (unlocks Custom HTTP Tools, card payments mid-call, and the MCP Developer Portal).
• Outbound Campaigns add-on: $49/mo (win-back and abandoned-cart calling).
