What is Slack?

Slack is a messaging application that helps teams collaborate online. Slack channels help organise company-wide communications into sub-categories, while direct messaging allows for one-on-one discussions. The app can be used whether you’re in the office or working remotely.

Slack’s offerings can be overwhelming for beginners, but the platform is designed to scale based on the role and responsibilities of each team member. Sub-contractors and part-timers may only be looped into a few channels, while supervisors and team leaders may have their finger on the pulse of 10 or more threads.

As a global business, Finder uses Slack. Jon Ostler, CEO of Finder UK says, “We collaborate closely with Finder offices around the world, and some of our UK crew are fully remote. Slack allows us to easily share ideas and files with each other, and keeps us working as one global team.”

Slack pricing and fees

Slack’s service plans can be paid for monthly, but discounted rates are available for those who pay annually. The provider quotes prices in US dollars – we’ve converted these to pounds sterling but this will fluctuate with exchange rates.

Pros and cons of Slack

Pros

  • App integration. Slack integrates with 2,000 apps across a variety of categories and industries, including data analytics, developer tools, project management, marketing, sales and finance.
  • Monthly billing. No contract is required and you can terminate your service with no cancellation fee.
  • Free service plan. Slack’s basic offerings – the messaging platform, video conferencing and app integrations – are available for free.
  • Learning database. Slack’s comprehensive learning library includes articles that can help you navigate both beginner and advanced platform features.

Cons

  • Expensive. Slack’s more sophisticated features come at a cost — its monthly membership fees are higher than many of its competitors, including Flock and Mattermost.
  • No phone support. Tech support is limited to 24-hour email inquiries. Paying customers (using the Standard plan and above) also have access to live chat support, but this is not available 24/7.

Verdict

Slack helps in-person and remote workforces organise communications with dedicated channels, one-to-one direct messaging and a generous sweep of app integrations. But it’s pricier than many of its counterparts and may be challenging for newcomers to master.
