Base CRM (Zendesk Sell)

What is Base CRM?

Base CRM was acquired by Zendesk in 2018 and relaunched as Zendesk Sell. It retains its original identity as a mobile-first, field-sales-friendly CRM with a strong native app, built-in power dialer, and a clean interface that prioritizes usability over feature sprawl. Today it occupies the sales CRM lane within the broader Zendesk customer experience platform.

Who is it for?

Sales teams that are already using Zendesk Support and want their CRM and support data unified in one view. Also a good fit for field sales reps who need a capable mobile app with offline editing and geolocation. Teams that don't use Zendesk Support will find the value proposition thinner — as a standalone CRM, the pricing is harder to justify.

Strengths

• Native Zendesk integration — support tickets, sales history, and pipeline data share a single customer record with Zendesk Support.
• Mobile app — one of the best-in-class mobile CRM experiences, with offline editing, voice-to-text notes, and geolocation.
• Built-in power dialer — call recording, transcription, and analytics included without a separate telephony tool.
• Clean interface — consistently praised for ease of use and fast onboarding for new reps.
• AI lead scoring — available on higher tiers, surfaces at-risk deals based on communication patterns.

What to consider

• No free plan; the entry Sell Team tier at $19/user/mo is limited and most teams need the Growth tier ($55/user/mo) for serious pipeline work.
• Custom reporting requires the Professional tier ($115/user/mo) and is still limited compared to Salesforce or HubSpot.
• As a standalone CRM without the Zendesk ecosystem, it is overpriced relative to competitors like Pipedrive or Zoho CRM.

Bottom line

Zendesk Sell earns its place if you are a Zendesk shop looking for a cohesive sales and support experience. The mobile app and calling features are genuinely good. But if you're not already in the Zendesk ecosystem, you can get comparable sales CRM features for less elsewhere.
