Pros & Cons
ConnectWise PSA
Pros
- Ticketing goes deep, with SLA timers, routing rules, and service boards for MSP service desks.
- Billing handles recurring agreements, time and materials, and prepaid blocks, and syncs with QuickBooks and Xero.
- Time entries link directly to tickets, projects, and agreements, which helps capture billable work.
- A large ecosystem through the ConnectWise Marketplace and native RMM ticket creation.
Cons
- Reviewers report a learning curve of several weeks, plus ongoing work to maintain boards and workflows.
- There are no public prices, and independent estimates of 75 to 145 USD per user per month exceed many rivals.
- Users mention a dated, cluttered interface and slow performance at peak times.
- Reviewers cite uneven support, account manager turnover, and price increases at renewal.
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.
