Tools to Avoid
Don't use multiple tools for the same function. One PM tool, one communication tool. Don't run Slack AND Teams AND Discord.
Don't use tools you don't use. Lots of agencies pay for tools nobody's actually using.
Don't use enterprise tools when SMB tools work. Salesforce is great at scale. But HubSpot free is better for most small agencies.
Don't over-automate. Zapier is powerful but adds complexity. Use it for real problems, not hypothetical ones.
Implementation Tips
1. Start small. Core tools first (PM, communication, time tracking). Add specialized tools as you grow and have specific needs.
2. Use integrations. Most tools integrate with each other. PM tool connects to Slack. Slack connects to calendar. Fewer separate systems.
3. Quarterly audits. Every quarter, review your tools. Are we using this? Is it delivering value? If not, cancel it.
4. Train your team. A tool is only valuable if people use it. Invest in training so people get value.
5. Negotiate pricing. Many tools will negotiate on volume or annual contracts. Ask.
Frequently Asked Questions
Should we use all-in-one tools like ClickUp or Notion? All-in-one tools are tempting but often lead to compromise. Specialized tools usually work better. Pick the best tool per function.
What about industry-specific tools? Use them if they solve a specific problem. But don't over-specialize. Most agencies can use generic tools.
How much should we spend on tools total? Aim for 1-3% of revenue. For a $500k agency, that's $5-15k/year or $400-1,200/month. If you're spending more, audit and cut.
Should we use free tiers or paid versions? Start with free. Upgrade when you outgrow it or when the paid version saves you time worth more than the cost.
Can Huddle replace our PM tool? No, Huddle aggregates tasks from multiple PM tools. You still need a PM tool. Huddle is a dashboard on top of it.
What if our team insists on a specific tool? Listen. Sometimes the team knows something you don't. But also have a clear process for tool decisions. Don't buy tools based on one person's preference.
How do we prevent tool sprawl? Clear policy: each function has one tool. If you're thinking about adding a tool, is it replacing something or adding a new function?
The right tech stack enables efficiency without overwhelming your team. Start lean. Add tools as you grow.
Audit quarterly. You'll find the right balance.
