What You'll Receive
Full Description
Stop wasting time on repetitive tasks. This service delivers a fully functional, production-ready automation workflow built inside n8n on your own VPS — complete with AI agent integration, robust error handling, and a retry mechanism so nothing falls through the cracks.
Whether you need to automate CRM updates, process incoming data, trigger email sequences, post to social media, or connect AI models to your internal tools, this is a hands-on build service by Zinn Digital — an AI Solutions Architect and PMP-certified Project Manager based in London, England.
**What is included in every tier:**
Every package includes a custom-built n8n workflow tailored to your use case. The workflow connects an AI LLM model (OpenAI, Claude, Gemini, or similar) and includes Retrieval-Augmented Generation (RAG) so your AI agent can draw on your own data. A pre-set conversational journey is configured, along with integration into your CRM or database, user authentication, and multi-language support. Full source code is delivered with every order.
**How it works:**
1. You place your order and share your requirements via the order chat.
2. Zinn Digital reviews your brief and may ask a small number of clarifying questions.
3. The workflow is built, tested, and delivered to your VPS environment within the agreed timeframe.
4. Revisions are handled promptly within the scope of the chosen package.
**The technology stack:**
n8n is self-hosted on your VPS and backed by a PostgreSQL database for stability and scalability. Third-party tools such as Slack, Notion, Google Sheets, and other popular platforms can be connected via API. AI models are integrated directly into the workflow logic, not bolted on as afterthoughts.
**Who this is for:**
This service suits founders, operations managers, developers, and business owners who want intelligent automation running on infrastructure they own and control — not locked inside a SaaS platform. It is ideal for teams ready to move beyond basic trigger-action tools and into genuinely intelligent, multi-step automated processes.
**Why Zinn Digital:**
Zinn Digital brings together certified project management discipline (PMP) and deep AI Solutions Architecture expertise. Every workflow is built with production reliability in mind — not just a proof of concept that breaks under real load. The team is based in London and delivers professional automation solutions built around your actual business operations.

Frequently Asked Questions
No. If n8n is not yet installed, the setup of n8n on your VPS with a PostgreSQL database is part of what we handle. Please mention in your requirements whether you need a fresh installation or whether n8n is already running.
You will need to share SSH access credentials or equivalent server access so that we can install and configure n8n and the PostgreSQL database. All access details should be shared securely through the order chat.
We can connect any major AI model with an accessible API, including OpenAI (GPT-4 and similar), Anthropic Claude, Google Gemini, and others. You will need a valid API key for whichever model you choose.
n8n supports a very wide range of integrations. Common examples include Slack, Notion, Google Sheets, various CRMs, and any service with a REST API. Let us know your specific tools when you submit your requirements and we will confirm feasibility.
A revision covers adjustments to the workflow logic, node configuration, or integration behaviour based on feedback you provide after the initial delivery. Changes that significantly expand the original brief — such as adding entirely new workflow branches or additional integrations — may be treated as a new order.
The Starter package covers one clearly defined workflow — for example, receiving data from a webhook, processing it through an AI agent, and pushing the result to a CRM or database. If your requirements involve multiple branching paths, several distinct triggers, or high data volumes, the Boost or Premium tier is likely more appropriate.
You receive the fully deployed and tested workflow running on your VPS, along with the full source code (n8n workflow JSON export). Optional written documentation is available as an add-on.
