n8n agency — workflows you own

Why teams choose n8n over closed SaaS automation

n8n is fair-code workflow software you can self-host on your VPC, Kubernetes cluster, or managed n8n Cloud. That matters when CRM data, HR records, or payment webhooks cannot leave your jurisdiction or pass through a US-only middleware.

Unlike black-box Zapier zaps, n8n exposes every HTTP request, JavaScript snippet, and credential scope in version-controlled JSON — so security and platform teams can audit what runs in production.

Architecture: queues, credentials, and failure modes

We design workflows with explicit error branches, retry policies, and dead-letter handling. Long-running jobs use sub-workflows and queue mode when throughput exceeds single-instance limits.

Credential storage uses n8n's encrypted vault or your secrets manager integration. We document which service accounts need which OAuth scopes before any workflow goes live.

For high-volume webhook ingress we place n8n behind your reverse proxy with rate limits and idempotency keys so duplicate events do not double-charge customers or spam Slack.

Custom nodes and code when native integrations fall short

When an internal API or legacy SOAP endpoint has no community node, we build custom n8n nodes or use the Code node with typed helpers — always with unit tests and pinned dependency versions.

We prefer native nodes for maintainability but never block delivery on upstream package gaps. Custom work ships with README, semver tagging, and a path to contribute back to the community if you want.

Self-host vs n8n Cloud — how we decide

Self-host when you need VPC peering to RDS, custom TLS certificates, or air-gapped staging. n8n Cloud when you want managed upgrades and your workflows only touch SaaS APIs with public endpoints.

We scope HA (Redis queue, Postgres, multi-main) only when uptime SLAs justify ops cost — not by default for marketing ops automations that can tolerate brief maintenance windows.

Governance, GDPR, and change control

Workflow exports live in Git; promotions from staging to production require PR review. PII fields are tagged in workflow metadata so DPA annexes list actual data flows, not generic "automation tool" language.

We deliver runbooks for credential rotation, backup restore, and n8n version upgrades — including breaking-change notes from the n8n release blog.

Commercial model and typical timelines

Indicative engagements from €3,800 for 3–5 production workflows plus staging environment; enterprise HA clusters and custom node libraries are quoted after integration inventory.

Most projects kick off within two weeks of signed SOW and API access. Weekly demos show workflow JSON, test executions, and alert routing before production cutover.
