The Minimalist Guide to SaaS Automation

Running a SaaS business shouldn’t require an army of tools. This guide shows you how to achieve maximum automation with a minimalist approach.

The Problem with Tool Overload

Many SaaS founders fall into the trap of adding tools for every conceivable function. This creates:

• Integration nightmares across disconnected systems
• Data silos that prevent holistic insights
• Subscription bloat eating into margins
• Cognitive overhead from context switching

The Minimalist Automation Stack

Here’s a lean stack that covers 90% of SaaS automation needs:

Core Infrastructure

Function	Recommended Tool	Why
Workflow Automation	Make (formerly Integromat)	Visual, powerful, affordable
Database	Supabase	PostgreSQL + Auth + Storage
Email	Resend	Developer-first, great deliverability
Analytics	PostHog	Open-source, full-featured

The 80/20 Automations

Focus on these high-impact automations first:

1. User Onboarding Sequences: Automated emails based on user actions
2. Churn Prevention Alerts: Notifications when usage drops
3. Billing Updates: Sync payment events to your CRM
4. Support Ticket Routing: Auto-categorize and assign tickets
5. Report Generation: Weekly metrics delivered automatically

Building Your First Automation

Let’s walk through a practical example: automated user activation emails.

// Webhook handler for new signups
export async function handleSignup(user) {
  // Add to email sequence
  await addToSequence(user.email, 'onboarding');
  
  // Track in analytics
  await track('user_signup', { userId: user.id });
  
  // Notify team in Slack
  await notifyTeam(`New signup: ${user.email}`);
}

Measuring Automation ROI

Track these metrics to ensure your automations deliver value:

• Time Saved: Hours recovered per week
• Error Reduction: Manual mistakes eliminated
• Response Time: Speed of customer interactions
• Conversion Impact: Effect on activation/retention

Common Automation Mistakes

Over-engineering

Start simple. A basic Zapier workflow beats an unfinished custom solution.

Ignoring Edge Cases

Test your automations with unusual inputs. Users will find creative ways to break things.

Set and Forget

Automations need maintenance. Schedule quarterly reviews of your workflows.

Scaling Automation Thoughtfully

As you grow:

1. Document Everything: Future you will thank present you
2. Build Monitoring: Know when automations fail
3. Plan for Volume: Consider rate limits and costs at scale
4. Stay Flexible: Requirements will change

Action Steps

1. Audit your current tools—what can be consolidated?
2. Identify your top 3 manual tasks by time spent
3. Build one automation this week
4. Measure the impact after 30 days
