Pros & Cons

Autotask PSA

Pros

  • Time logged on tickets and project tasks flows into contract billing and invoicing, which reviewers say reduces revenue leakage.
  • Tight integration with Datto RMM, IT Glue and the Kaseya IT Complete suite, plus an API with more than 170 listed integrations.
  • ITIL-aligned ticketing with SLA tracking and alert-to-ticket automation that cuts duplicate tickets.
  • Customizable dashboards and pre-built utilization and profitability reports for MSP managers.

Cons

  • Users call the projects module underdeveloped for real project planning, and many add third-party Gantt tools.
  • Steep learning curve, click-heavy interface and long, costly implementation.
  • No public pricing, and reviewers report seat minimums, multi-year contracts and upselling since the Kaseya acquisition.
  • Custom reporting and the automation rules are hard to configure without technical help.

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.
