Pros & Cons
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.
Slack
Pros
- The app ecosystem is very large, and tools such as ClickUp, Notion, HubSpot and Clockify can post updates into channels.
- Slack Connect lets teams work in shared channels with up to 250 outside organizations on paid plans.
- Compliance coverage is broad, including ISO 27001, SOC 2 Type II, FedRAMP Moderate and HIPAA configurability.
- Lists add table and board layouts with assignees, due dates and subtasks, without leaving chat.
- Workflow Builder automates routine requests and approvals without code.
Cons
- There are no native Gantt charts, dependencies, time tracking or portfolio reporting, so Slack doesn't replace a dedicated PM tool.
- Frequent notifications and busy channels can interrupt focus, a common complaint in reviews.
- The free plan keeps only 90 days of message history and allows 10 apps.
- Advanced AI features require Business+ or above, and per-user costs add up as teams grow.
- Reviewers report that finding older messages through search can be difficult.
