n8n vs. Zapier for home-service automation: 18 months of real implementation data

The honest answer is: it depends. The unhelpful version of that answer is: “every situation is unique.” The helpful version is: there are three real criteria.

Pick Zapier when

• Your team needs to maintain the automation without engineering help.
• The logic is mostly linear — trigger, transform, send.
• You are integrating with one of the 1,000+ apps Zapier supports natively.
• You can live with the per-task cost. Above ~30K tasks/month, the math changes.

Pick n8n when

• You have at least one technical person who is comfortable with conditional logic, JSON, and self-hosting (or paid cloud).
• The logic is branchy — IF/ELSE, loops, retries, error handling.
• Costs at Zapier are pushing past $400/month and climbing.
• You want to keep custom code (JavaScript, Python) inline with the workflow.

Pick neither when

• The integration is native between the two products. ServiceTitan ↔ QuickBooks is native. Do not Zapier it.
• The automation is replacing a person who should not have been doing it manually. Sometimes the right fix is a workflow inside HubSpot, not an external tool.
• The automation will run twice a year. Just do it manually.

What the 18 months of data actually showed

We have shipped roughly 60 automations across home-service clients. Zapier was the right call in about 55% of cases. n8n in about 35%. Native tools or “do not automate this” in about 10%.

The single most common mistake: reaching for Zapier when the native integration would have been better. The second: reaching for n8n when the team had nobody to own it.
