ClickUp

Pros

• Deals can become delivery projects in the same workspace, which suits agencies and consultancies that sell and deliver client work.
• The free plan allows unlimited members and unlimited tasks, so small teams can try the platform before paying.
• Custom fields, task types, many views and automations let teams model most pipelines and processes without code.
• Enterprise security options include SAML, SCIM, audit logs, data residency and HIPAA support with a BAA.

Cons

• It is not a dedicated CRM. Reviewers report needing Zapier automations for CRM workflows, and the CRM page does not confirm email sync or native calling.
• Reviewers report a steep learning curve and say new users need hours of training to become proficient.
• G2 and Capterra reviewers report bugs, slow performance and support replies that do not resolve problems.
• The late-2026 pricing change raised per-user list prices for new workspaces, and heavy AI use requires buying extra credits.

Sierra

Pros

• Outcome-based billing means customers usually pay only for resolved conversations or other agreed results, not for each seat.
• Three build options cover both CX teams and engineers: the no-code Agent Studio, the code-first Agent SDK, and Ghostwriter for building agents from SOPs.
• One agent runs across chat, voice, SMS, WhatsApp, email and ChatGPT, keeping context between channels.
• Its list of compliance attestations is broad, covering SOC 2, ISO 27001, ISO 42001, HIPAA, PCI DSS and FedRAMP.
• It has a strong roster of enterprise customers, including SiriusXM, ADT, Rocket Mortgage and SoFi.

Cons

• There is no public pricing, and competitor estimates put annual contracts at about $150,000 or more.
• There is no self-serve or trial tier, so small teams cannot try it on their own.
• Implementation is largely vendor-led, which can make customers depend on Sierra's team for changes.
• There are few public reviews (7 on Gartner Peer Insights) to verify claims against.
• Some reviewers say voice quality still falls short of human level, and that complex telephony setups depend on how far the integration goes.
