How to choose
Choose Slack when the buying team values teams that need chat, channels, and workflow apps and wants a contract structure aligned with seat-based collaboration plans. Choose Zoom when the main need is teams that prioritize meetings and webinars and the team is comfortable reviewing host-based communications pricing.
Before approving either product, compare total cost of ownership, implementation effort, administrator workload, integration dependencies, and renewal notice dates.
Vendor questions
- Which features in the demo are included in the quoted edition?
- What fees appear after the first year?
- How are users, viewers, guests, admins, and API usage counted?
- Can the vendor provide a clean data export before contract end?

Normalize the commercial response
- Use one user and usage forecast for both quotes.
- Separate recurring licenses, usage, implementation, support, dependent tools, and administration.
- Record renewal notice, price change, downgrade, export, and termination-assistance terms.
- Model the expected case and a stress case instead of relying on the first-year headline.
