n8n Automation

We start by sitting with your team to see the work they repeat every day, and pick the first two or three workflows that pay back fastest. Then we install n8n on your server or cloud account: your data and credentials stay in your system, the encryption key is yours, and the self-hosted Community edition is used for your internal work under the terms of its Sustainable Use License. Every workflow has an error workflow behind it, retries for steps that stumble, an alert to LINE or email when a step really fails, and a log of every execution so you can see what each step received and sent.

The n8n AI Agent is a node that connects a language model such as Claude or GPT to tools, such as reading a sheet, searching documents or calling an API, and lets the model choose which tool to use for the task it was given. We use it where the input has no fixed shape: order emails that every customer types differently, requests arriving on LINE, replies drafted from your own documents. Where the rules are clear we use ordinary nodes, because they cost less to run, finish faster and are easier to check. And when your case is an agent that must hold a long conversation with customers or process heavy loads, we say so and build it as code or as a separate AI Agent service, with n8n calling it.

Wherever a step touches money or a customer there is a human approval step: the workflow waits, sends a message with approve and reject buttons to Slack or LINE, and continues when someone presses, recording who and when. At the end we hand over the workflow files with node-by-node documentation, per the scope in the contract, and train your team, so they can change a message, add a column or swap an approver without waiting for us. A first set of workflows usually takes two to six weeks. After that your team can run it alone, or we look after it monthly.
