Bluemoon – n8n Automation with AI for a Marketing Agency

Starting point

Bluemoon already had initial automations in place: lead intake and order processes ran via make.com, n8n, ClickUp and Windows server scripts. But more complex processes were hard to envision, existing workflows were partly fragile, and the know-how for APIs, custom nodes and complex logic was missing.

Solution

1.5 days of hands-on work directly on the client’s real systems:

• Existing workflows analyzed, fixed and improved
• APIs, custom nodes and complex workflows in n8n, including error subworkflows with notifications
• AI-assisted workflow building: define requirements cleanly, generate a first version as a JSON template with Claude, connect systems such as Outlook/MS365 and iterate from there
• Concrete use case: Outlook trigger for invoice intake

The result was a roadmap for the next AI automations (German): invoice dispatch and dunning with human-in-the-loop approval, automated social media replies and a WooCommerce integration.

Technology stack

• n8n (APIs, custom nodes, complex workflows, self-hosted in Docker)
• Claude (AI-assisted workflow creation via JSON templates)
• make.com & ClickUp (existing automation landscape)
• MS365 / Outlook integration (mailbox monitoring, invoice intake)
• Webhooks & error subworkflows with notifications

Result & Impact

• Over 60 hours of manual work that can be automated: in invoice intake alone, around 800 transactions at 5 minutes each
• Training costs recouped immediately on paper
• Existing workflows stabilized and improved
• The team now builds automations itself, AI-assisted with Claude and n8n
