How to choose a business automation platform: technical criteria and common mistakes
Published: February 19, 2026
Choosing the wrong automation platform forces a migration in 12 months. The most common mistakes are over-engineering with an enterprise solution when n8n solves the problem, or underestimating complexity and ending up with manual workarounds that negate the benefit.
This technical guide targets operations and technology leads at mid-sized Spanish companies needing to choose a business automation platform. If you have between 20 and 500 employees and want to reduce manual work without getting trapped in a platform that doesn't scale, these criteria will save you a costly migration in 12 months.
Comparison: Make, Zapier, n8n, and custom software
- Zapier: ideal for simple integrations between popular SaaS tools (HubSpot, Slack, Gmail). Volume and customization limits. Price scales quickly.
- Make (formerly Integromat): more powerful than Zapier, allows complex conditional logic and data transformation. Better price/performance for mid-size processes.
- n8n: open-source, self-hosted or cloud. Full control over data, no operation limits. Requires technical skill to maintain and scale.
- Custom software: when business logic doesn't fit any iPaaS or operation volume makes per-execution cost prohibitive.
When each option is the right choice
- Zapier/Make: SaaS-to-SaaS automations, under 50k operations/month, no sensitive data in transit.
- n8n: sensitive data (customer, financial), high volumes, need for full flow control and logs.
- Custom software: legacy system integration, complex business logic, fast-evolving processes.
- Mix of options: use iPaaS for lightweight integrations and custom software for core business logic.
Technical criteria you cannot ignore
- Current and projected operation volume at 24 months: directly impacts cost.
- Data in transit: does it contain PII or financial information? Defines whether you can use shared cloud.
- Acceptable latency: real-time automations vs batch processing completely change the architecture.
- Team capability to maintain the platform: n8n without a technical team generates technical debt fast.
How to avoid the migration trap
- Document the full process before choosing a tool: many projects fail by implementing without design.
- Start with a non-critical process to learn the platform before scaling.
- Define migration criteria from the start: what has to happen for you to switch platforms.
- Avoid vendor lock-in on critical business logic: keep code or workflows exportable.
