Invoice Automation Production Deployment
Budget: €250 – €750 EUR
I have a proof-of-concept workflow that extracts data from incoming invoices, routes it through n8n, and posts the results into a simple database. The next step is to harden that flow and run it in production so the finance team can push sales, purchase, and recurring invoices through it without babysitting each job. Efficiency is the driving metric: fewer clicks, faster postings, and clear audit trails.
Here is what I need refined or built:
• Containerised n8n instance running behind Docker Compose with proper env-file management, webhooks, and health checks.
• Integration with NocoDB as the primary data store; CRUD operations must be abstracted behind REST calls so downstream tools can interact with it predictably.
• JavaScript function nodes inside n8n to handle field mapping, date math, and edge-case validation.
• Error handling and retry logic that surfaces failures to email and Slack.
• Minimal but solid logging—ideally shipping JSON logs to a volume or external service.
• A one-click deployment script for the staging and prod stacks.
The existing POC uses mocked data and flat CSVs. You will turn that into live endpoints, tidy up the workflow, and document any new environment variables or API keys. If you happen to have Claude AI or Airtable experience, that is a plus; the architecture may expand in that direction later.
Acceptance criteria
1. All three invoice types flow end-to-end with no manual touch and with validation tests passing.
2. A fresh developer can clone the repo, run docker compose up, and hit a test webhook to see data land in NocoDB.
3. Error conditions (bad schema, network timeout, auth failure) trigger the agreed notifications and leave detailed logs.
I will provide current n8n export files, sample invoices, and access to a staging VPS. Code review will happen via GitHub PRs. Once the prod pipeline runs smoothly for a full week, the engagement is complete.
