I deliver of fix one n8n workflow: single trigger, single destination, single integration, an explicit failure path,. I demo the JSON for you via live video call or recorded loom. I send JSON you import and run.
$150 fixed. You pay after you see it run in your instance. Company invoice. Async; no obligatory call.
Not a fit: unpaid tests, 31-agent builds, full agency ops.
Reply with trigger, destination, and what must not happen on a second run. I’ll answer yes/no in one message.
Webhook trigger to Google Sheets destination, with an Error Trigger node routing failures to Slack, and a de-duplication step using a unique transaction ID to prevent duplicate second runs. What is the explicit unique identifier we are using to prevent duplicate processing on retries? Before I write any code I ask for a small deposit up front (roughly 30% of the agreed price, refundable if I can’t deliver) - keeps a first project low-risk for both of us, non-negotiable.
