Your n8n workflows
white-labeled

Everything you need to prepare so your automations run reliably and under your full control — n8n instance, API keys, webhooks, and data storage.

What we'll automate

Workflows that replace hours of manual work: email parsing, data routing, lead enrichment, multi-channel publishing, tool sync, smart notifications, AI agents.

Concrete examples

Inbound lead → enriched CRM + Slack alert

Form submitted → enrichment via Apollo/Hunter → CRM record creation → scoring → real-time sales alert.

Customer support AI agent

Incoming email → AI classification → drafted reply → human escalation if complex → archiving with tags.

Multi-channel publishing

1 piece of content in Notion → platform-specific formatting → publish to LinkedIn / X / Facebook / blog with optimized images per platform.

Automated reporting

Data aggregation (Stripe + GA4 + HubSpot) → weekly PDF report → sent to stakeholders.

White label: the n8n instance, the database, the API keys of connected services — everything is in your name. I hold nothing in mine.

Where to host n8n

Two options. I strongly recommend the first unless you have specific constraints.

Advanced

Self-hosted (Render, VPS, Hetzner)

You host the n8n instance on your own infrastructure.

  • Cheaper baseline (~$7–15/month on Render or VPS)
  • Full control, no execution limits
  • Sensitive data 100% on your infra
  • Maintenance on you (monthly updates)
  • SSL, backups, monitoring to configure yourself
  • A crash = workflows down until intervention
  • Long-term technical debt risk
My advice: start with n8n Cloud. The $10–15/month price difference is absorbed the first time an incident is avoided. Move to self-hosted only if you exceed Cloud quotas or have strict regulatory constraints (mandatory local hosting).

Accounts & services to prepare

Depending on your workflows, some accounts are mandatory, others optional. I'll tell you exactly which ones after analyzing your needs.

n8n Cloud (or host)Required

Instance running your workflows. I recommend n8n Cloud (see p. 02).

Link: n8n.io/cloudPlan: Starter $20/month (2,500 executions)My role: Member Editor
Database for storageOften required

To store data your workflows produce (leads, logs, intermediate states). Options: Supabase, Airtable, Google Sheets, Notion. I help you choose based on the case.

Supabase: supabase.com (DB + API)Airtable: airtable.com (spreadsheet UI)Plan: Free to start
Email workspaceDepending on use

If your workflows send or read emails: Google Workspace, Microsoft 365, Zoho Mail, or Resend (transactional only). I use whichever system you already have — no migration needed.

Gmail: OAuth in n8nOutlook/Office 365: OAuth in n8nResend: API key
API keys of integrated toolsRequired

For every tool your workflows will control, you generate an API key from your account. I provide the exact procedure for each.

Examples: Stripe, Slack, Notion, Airtable, HubSpot, Calendly, Typeform, Google Sheets, OpenAI, Anthropic, Telegram, WhatsApp Business, etc.
Webhooks of source toolsDepending on triggers

A webhook = URL provided by n8n, pasted into the config of the tool that triggers the workflow (e.g. new Typeform lead, new Stripe payment, new Slack message). The source service automatically pushes data to n8n when the event happens.

I provide: the n8n webhook URLYou configure: the destination inside your source tool
OpenAI / AnthropicOptional (if AI)

If your workflows use AI (classification, writing, extraction, RAG). Account to create, API key to generate, monthly cap to set to avoid overspending.

cron-job.orgOptional (if Supabase Free DB)

If your workflows use a Supabase Free DB, it pauses after 7 days of inactivity. A free cron pings the health URL every 3–5 days to keep it active. Not needed with Supabase Pro or another DB.

Who does what

Clear split. You provide access and business logic; I design and implement the workflows.

What I do

  • Needs analysis & workflow mapping
  • Architecture choices (sync/async, queues, retry)
  • Building workflows in n8n
  • Integrating your tools (OAuth, API keys)
  • Error handling, logs, notifications
  • Testing with real data before go-live
  • Per-workflow documentation (input, output, logic)
  • Training for reading / basic editing

What you do

  • Create the n8n Cloud account (or host)
  • Create the required tool accounts
  • Generate API keys from your accounts
  • Configure webhooks on the source tool side
  • Provide business rules (e.g. "if lead > 50 pts → alert Sophie")
  • Validate workflows with real use cases
  • Handle n8n + third-party billing
  • Decide on future iterations

API key security

Principle: the API keys you generate give me access to your accounts. Use keys with the minimum permissions needed, and revoke them if you remove my access.

Storage: all keys are stored encrypted inside n8n, never in code or Git. At delivery, you keep full control of credentials.

Audit: every service (Stripe, Google, etc.) lets you view active access and revoke it anytime from their console.

Delivery & costs

Handover flow and typical recurring costs.

Delivery flow

Real-world testing — each workflow runs 7 to 14 days with your real data to catch edge cases.

Documentation — a PDF per workflow: diagram, inputs/outputs, business rules, debug procedure, service contacts.

Training (1 h) — video call to learn how to read executions, re-run a workflow, change a threshold or add a recipient.

Ownership transfer — you already own the n8n instance and tool accounts. I remove my access or keep it for maintenance (your call).

Warranty — 30 days of bug fixes included after delivery for anything within the agreed scope.

Maintenance (optional) — monthly retainer to monitor executions, fix bugs from third-party API changes, add small iterations.

Typical recurring costs

n8n Cloud Starter~$20/month

2,500 executions / month. Smooth scaling if your usage grows.

Database$0–25/month

Supabase Free to start, Pro ($25/month) for serious production.

Tool API keysVariable

Most are free. Some have quotas (e.g. OpenAI pay-as-you-go, WhatsApp Business per message).

AI (OpenAI / Anthropic)Pay-as-you-go

Usage-based billing. Example: GPT-4o-mini ≈ $0.15 / 1M input tokens. Set a monthly cap in the console.

Typical estimate: $25–60/month for a pack of 3 to 5 active workflows, depending on volume and AI usage.
