TL;DR

  • Pick Base CRM (zendesk-sell">Zendesk Sell) if you already run Zendesk Support and want sales and support unified on one record, plus a top-tier mobile app for field reps.
  • Pick Follow Up Boss if you run a real estate team and want leads from 250+ property sources routed to agents automatically with calling and texting built in.

A Zendesk sales tool vs a real estate operating system

Base CRM, relaunched as Zendesk Sell after Zendesk's 2018 acquisition, is a general-purpose, mobile-first sales CRM. Its reason to exist is the Zendesk ecosystem: support tickets, sales history, and pipeline data live on a single customer record, so a team running Zendesk Support gets a cohesive sales-and-support view. Outside that ecosystem, it is a clean but fairly ordinary CRM whose pricing is hard to justify against Pipedrive or Zoho.

Follow Up Boss is not a general CRM at all — it is a real estate operating system. It pulls leads from Zillow, Realtor.com, website providers, and 250+ sources, routes them to the right agent the moment they arrive, and drives follow-up through action plans built around property deals. That vertical focus is why 41 of the top 50 U.S. real estate teams use it, and why it has no use outside real estate.

The decision is about industry, not feature count. Zendesk shops selling B2B choose Base CRM; brokerages choose Follow Up Boss.

Pricing

Base CRM (Zendesk Sell) starts at $19/user/mo (Sell Team), but that tier is limited — most teams need Growth at $55/user/mo, and custom reporting requires Professional at $115/user/mo. There is no free plan. Follow Up Boss starts at $69/user/mo (Grow), with a Pro plan at $499/mo for 10 users and a 14-day free trial. Base CRM is cheaper to enter, but Follow Up Boss's higher price buys real estate-specific lead machinery that would be impossible to replicate in Base CRM.

Mobile and calling

Both invest in phone-based selling but from different angles. Base CRM ships a best-in-class mobile app with offline editing, voice-to-text, and geolocation, plus a built-in power dialer with recording and transcription — a strength inherited from its field-sales heritage. Follow Up Boss centers on speed-to-lead calling and texting: the goal is to get a new lead on the phone before a competitor does. Field reps favor Base CRM's app depth; real estate agents favor Follow Up Boss's follow-up automation.

Where each one stalls

Base CRM's weakness is dependency — without Zendesk Support it is overpriced for what it does. Follow Up Boss's weakness is narrowness — it is superb for property and useless elsewhere, and its calling add-ons can inflate the monthly bill. Both are strong inside their lane and weak outside it.

Who should pick what

  • Team already running Zendesk Support → Base CRM.
  • Real estate agent or brokerage → Follow Up Boss.
  • Field reps who need a great mobile app → Base CRM.
  • Team drowning in Zillow / Realtor.com leads → Follow Up Boss.
  • General B2B sales on a budget entry price → Base CRM.
  • Property team wanting instant lead routing → Follow Up Boss.

Bottom line

These tools do not really overlap. Base CRM (Zendesk Sell) earns its keep for Zendesk shops that want unified sales and support and a strong mobile app. Follow Up Boss is vertical software that top real estate teams reach for because nothing generic matches its lead routing. Decide by industry first, and the choice makes itself.

Frequently asked questions

Base CRM (Zendesk Sell) vs Follow Up Boss — which is better?
It depends on your industry. Base CRM is better for general B2B sales teams already using Zendesk Support who want a unified sales-and-support record and a strong mobile app. Follow Up Boss is better for real estate teams that need leads from Zillow and Realtor.com routed automatically. Zendesk shops lean Base CRM; property teams lean Follow Up Boss.
Is Base CRM cheaper than Follow Up Boss?
Yes at entry — Base CRM starts at $19/user/mo versus $69/user/mo for Follow Up Boss Grow. But the entry Base CRM tier is limited; most teams need the Growth tier at $55/user/mo for serious pipeline work. For real estate specifically, Follow Up Boss delivers lead routing that Base CRM cannot match at any price.
Can Base CRM (Zendesk Sell) be used for real estate?
It can store contacts and deals, but it has none of Follow Up Boss's real estate lead aggregation from 250+ property sources or its action plans built around property transactions. For a brokerage, Base CRM is a generic container you would have to adapt. Follow Up Boss already speaks the industry's language.
Which has the better mobile app?
Base CRM is known for a best-in-class mobile experience with offline editing, voice-to-text notes, and geolocation — a legacy of its field-sales roots. Follow Up Boss has a capable mobile app centered on calling and texting leads. For field reps who edit records on the road, Base CRM's app has the edge.
Do I need Zendesk Support to use Base CRM?
No, but the value drops sharply without it. Base CRM's standout feature is sharing one customer record between Zendesk Support tickets and sales pipeline data. As a standalone CRM it is priced higher than comparable tools like Pipedrive or Zoho. Follow Up Boss, by contrast, needs no other product to deliver its value.
