# Best Kartra Alternative for Agencies & Builders

> 500 contacts on the entry tier isn't a real local-business CRM. SeldonFrame gives every client an AI receptionist, website, CRM, and booking system for $29/mo flat, with no contact caps.

## The short version

- **Kartra pricing:** Essentials **$59/mo** (500 contacts) / Starter **$119** / Growth **$229** / Pro **$549** — contact caps every tier
- **SeldonFrame pricing:** **$29/mo** **flat**, **unlimited workspaces**, first workspace **free forever**
- **Pick Kartra if:** You're a creator or coach selling courses or memberships
- **Pick SeldonFrame if:** You're a service business, not a course seller

## Kartra vs SeldonFrame: what you need to know

Most people looking for a Kartra alternative hit the same wall: contact caps everywhere. Essentials runs $59/mo but caps at just 500 contacts, Starter $119/mo, Growth $229/mo, Pro $549/mo — every tier has a ceiling that forces an upgrade as your list grows. There's no white-label or sub-account option for agencies, and no phone or local-business tools at all. Kartra is built for selling courses and memberships, not answering calls and booking jobs.

That said, Kartra is impressive. Its course, membership, video, and affiliate tools and built-in helpdesk are genuinely deep for a creator-economy business. If you're selling a course with an affiliate program, it's a strong fit. But local service businesses don't sell memberships. They answer phones and book jobs, and a 500-contact cap won't survive a busy month.

## Why agencies & builders switch from Kartra

- **An AI receptionist for a phone Kartra ignores** — Kartra has no phone or SMS layer. SeldonFrame's agent answers calls, qualifies leads, and books real jobs into a calendar.
- **Built for service businesses, not just course sales** — SeldonFrame's booking calendar, intake forms, and CRM are built for scheduling client work, not just selling a membership.
- **Whitelabel for agencies** — Kartra has no agency resale model. SeldonFrame includes a branded client portal and per-client workspaces at $29/mo.

## Who should use Kartra vs SeldonFrame

Choose Kartra if:
1. You're a creator or coach selling courses or memberships
2. You want built-in affiliate management and a helpdesk
3. Video or membership hosting is core to your offer

Choose SeldonFrame if:
1. You're a service business, not a course seller
2. You want no contact cap to outgrow
3. You need an AI receptionist Kartra doesn't offer
4. You're an agency needing whitelabel client workspaces

To be fair: Choose Kartra if you're a creator or coach selling courses, memberships, or video content and want built-in affiliate management and a helpdesk alongside checkout.

## How to switch from Kartra to SeldonFrame

1. **Build the replacement free (3 minutes)** — Paste the business's website into seldonframe.com. SeldonFrame pulls out services, FAQs, and business facts and builds the workspace: site, CRM, booking calendar, intake, and the AI agent. No account needed until you claim it.
2. **Bring what matters over** — Export your Kartra contacts to CSV and import them. SeldonFrame's booking calendar replaces any client-scheduling workflows you'd built around Kartra's checkout pages.
3. **Connect your keys and number** — Add your AI key (Claude, ChatGPT, or Gemini — about 30 seconds) and, for phone, connect your Twilio number so calls and missed-call text-back run at carrier cost.
4. **Test the agent, then go live** — Every agent ships with automatic tests. Talk to it, watch it book into the calendar, then publish. Point your domain over when the site's ready.
5. **Run both in parallel for a week** — Keep the old tool running while SeldonFrame answers the phones. Cancel it once the CRM shows the bookings landing — cancel-anytime on both sides means zero risk.

## FAQ

**Does SeldonFrame sell courses or memberships like Kartra?**

No. SeldonFrame is built for local service businesses: an AI receptionist plus the website, CRM, and booking calendar behind it. It doesn't include course-hosting or membership-site tools.

**Will I hit a contact cap on SeldonFrame like Kartra's tiers?**

No. $29/mo is flat with no contact cap, at any tier.

**How can SeldonFrame be $29/mo flat when competitors charge per minute or per credit?**

Because you use your own keys. Your agents run on your own AI key (Claude, ChatGPT or Gemini) and, for phone, your own Twilio account. You pay the providers at raw cost. SeldonFrame never marks up tokens or minutes. You pay for the platform, not a meter.

**Do you take a cut of what I charge my clients?**

SeldonFrame works like Shopify: $29/mo flat, plus 2% on sales made through SeldonFrame checkout, plus 5% when you sell agents on the SeldonFrame marketplace. Client retainers you bill outside SeldonFrame cost nothing extra.

**How fast can I see it working?**

Paste in a business's website (or just describe it in a sentence). SeldonFrame builds the whole workspace — site, CRM, booking, intake, and the AI agent — in about 3 minutes. It's free, and you don't need to sign up first.
