Pros & Cons
FreshBooks
Pros
- The pop-up timer turns billable hours into an itemized client invoice in one click.
- Project budgets and profitability tracking sit next to the accounting data, so there is no separate sync.
- The project Discuss area lets teams and clients share files and comments.
- Reviewers repeatedly praise the clean, simple interface.
- Accountant access is free on all plans.
Cons
- There are no Gantt charts, project diagrams or advanced task planning.
- Every plan caps or prices by billable clients, and Lite allows only 5.
- Each extra team member costs $11 a month, which adds up for growing teams.
- Project management cannot be bought separately from the accounting suite.
- Reviewers say collaboration is more limited than in dedicated tools like Asana or Monday.
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.
