Workflow v01 margin guardrail is an n8n automation template for margin control and financial guardrails in field service or construction businesses. Reach for it when you need to automatically reject work orders that breach a margin threshold, when labor cost overruns keep slipping through without manual checks, or when crews submit change orders and you want them validated against financial rules before approval. Trigger: webhook — an external system posts job or order data, the workflow checks margin, labor limits, and validation rules, then returns a decision or passes the result downstream. This template is part of a set of 8 interconnected workflows covering field service and construction operations, including change order sync and payout calculation. Direction — inbound financial validation, not outbound reporting or analytics. This is an automation tool, not financial advice; all decisions and risks remain with the user. Works with n8n self-hosted or cloud; requires webhook support on the calling system side.
