We compared price, client collaboration, and security.

Slack has a free plan, then $7.25 or $15 per user per month on annual billing. Zoom has a free Basic plan, then $14.16 or $18.33 per user per month with annual billing selected.
| Tool | Plan | Price | What stands out |

Which costs less?
Zoom Pro costs more than Slack Pro per user, but it bundles meetings, chat, phone, mail, and AI notes. Slack is cheaper if you only need messaging.
Both have a useful free plan, but Slack hides history after 90 days and Zoom ends meetings at 40 minutes.
Many agencies pay for both, so compare the combined cost with what a single bundle could replace.
Which is better for working with clients?
It depends on the interaction. Slack Connect gives clients a shared channel with your team on paid plans, which suits ongoing projects. Zoom suits scheduled calls, workshops, and webinars.
Clients already know how to join a Zoom link, while a shared Slack channel needs onboarding.
Which has stronger security evidence?
Slack, on the pages checked: SOC 2 Type II, ISO 27001, HIPAA support on Enterprise+, data residency from Business+, and a statement that customer data is not used to train models. Zoom lists end-to-end encryption and GDPR controls on every plan, SAML SSO from Business, and regional data centers from Pro, but SOC 2 and ISO were not stated.
Check the plan that carries each feature.
How do Slack and Zoom compare on integrations, security, and support?
