What a Specialist n8n Agency Actually Does
Most businesses dabble with n8n templates and hit a wall. We go further — designing the full automation architecture, handling edge cases, building error-handling loops and monitoring every workflow 24/7.
Workflow Architecture
We map your entire operation before writing a single node. Every workflow has a purpose, an owner and a fallback. Nothing is bolted together at random.
n8n Custom Node Development
When the built-in nodes do not cover your API, we write custom JavaScript nodes. Your CRM, ERP, booking system — if it has an API, we can connect it.
Production Deployment & Monitoring
24/7 error monitoring with Slack alerts. Every workflow has retry logic, dead-letter queues and a dedicated runbook. Nothing breaks silently.
Ongoing Optimisation
n8n updates monthly. We test every upgrade against your workflows before it touches production. Your automation never drifts.
Full Documentation Handoff
Every workflow we build is fully documented — logic diagrams, data dictionaries, maintenance notes. No black box. You own everything.
Training & Enablement
We run a live training session with your ops team so they can extend and monitor workflows confidently without coming back to us for every change.
