Self-hosted n8n, monitored,automations that hold up in production.

Scroll deploys n8n on your infrastructure: versioned like code, monitored, with no dependency on an automation SaaS. From emails to ERP, from CRM to business files, we industrialise your processes without making them fragile.

01 — Real use cases

n8n in our projects,
the automations we deploy.

No demos. Six automation workflows we put into production, from invoice processing to lead qualification, each connected to your actual tools.

01

Invoice reconciliation & processing

Data extraction from invoices (OCR + AI), matching with purchase orders, writing to the ERP. Exceptions are flagged for human review; the rest runs automatically.

02

Lead qualification & enrichment

Every incoming lead is enriched, scored, and routed to the right salesperson in the CRM. No more manual entry, no more leads sitting idle in an inbox.

03

File processing & onboarding

Document collection, automatic follow-ups, checks, account and access creation. The file progresses without a human pushing each step.

04

Inter-IS synchronisation

Connecting tools that don’t speak to each other: ERP, CRM, billing, support. n8n bridges the gap, with explicit, versioned business logic.

05

Sorting & responding to communications

Detect genuine sales inquiries in the email flow, qualify them with AI, and push them into the ERP without re-entry. This is exactly the Imalize project.

06

Operational monitoring & alerting

Monitor business thresholds, aggregate signals, and alert the right person on the right channel. A safety net with follow-ups and escalation in case of failure.

02 — What we address from the start

Production-grade automation,
not a makeshift solution that fails silently.

"Building an n8n workflow" and "running n8n in production" are not the same. The difference lies in four key areas we address from the design phase.

Self-hosted & sovereign

n8n runs on your infrastructure (OVH, Scaleway, private cloud). Data and credentials do not pass through a third-party SaaS—essential when handling customer data or sensitive documents.

Versioned like code

Workflows don’t just live in the visual editor: they’re exported, versioned in Git, and deployed reproducibly. We review changes, roll back, and test in staging before production.

Monitored in production

Logs, monitoring, alerting. If execution fails, the system retries and then alerts with a direct link to the incident. An automation that fails silently costs more than no automation at all.

Reversibility

No lock-in: n8n is open source, workflows and data belong to you. We transfer operations to your team with documentation and training whenever you’re ready.

Client case — Imalize

From sales emails to the ERP,
in a sovereign workflow.

At Imalize, opportunities arrive by email, lost in the noise. Scroll deployed a self-hosted n8n workflow on their infrastructure: monitoring Outlook inboxes, detecting technical attachments, qualifying with a Mistral AI agent (French sovereign model), then automatically writing to the Dolibarr ERP via API—no re-entry required. Data and technical plans never leave the company’s controlled perimeter.

03 — In the stack

How n8n integrates
into a Scroll automation workflow.

n8n orchestrates: it triggers, routes, transforms, and calls. Around it, open-source components and sovereign models complete the chain: AI, databases, connectors, monitoring.

04 — Hosting

Cloud or self-hosted,
how do we choose?

n8n is available as a managed Cloud version or self-hosted. The choice hinges on one criterion: can your data and credentials transit through a third-party service, or must they remain on an infrastructure you control?

n8n self-hosted

OVH / Scaleway

Our default recommendation. n8n runs on your infrastructure: credentials, data, and documents never leave your perimeter. Updates, monitoring, and backups are managed by Scroll or handed over to your team.

Recommended when

Customer data or sensitive documents, sovereignty requirements, high execution volume, or need for custom connectors.

n8n Cloud

Managed

The managed version of n8n: no ops to handle, automatic updates, quick start. Executions run on n8n’s infrastructure, which is acceptable when data is not sensitive.

Recommended when

No sovereignty constraints, no ops team, prototyping, or moderate volume with non-sensitive data.

05 — FAQ

Frequently asked questions

The questions that come up during scoping. If yours isn’t here, get in touch!

Yes. We audit your current scenarios, identify what’s worth migrating to self-hosted n8n (sovereignty, execution cost, complex logic), and rebuild the workflows with explicit, versioned business logic.

The calculation is based on the human time saved and the risk of error avoided, not just volume. A repetitive task of a few minutes, repeated dozens of times a day, is often cost-effective. We assess ROI before development—sometimes the answer is “not yet.”

When required, yes. We prioritise Mistral, a French model, and can host open-source models (Llama, Mistral) on sovereign GPUs. Sensitive data then never transits through any American service.

Scroll can handle operations (monitoring, updates, evolutions) via a support contract, or transfer responsibility to your team with documentation and training. The workflows and data belong to you from the start.

Yes, it’s one of its strengths. We integrate LLM models (Mistral, OpenAI, Claude), OCR, embeddings, and RAG directly into workflows: email qualification, document extraction, response generation. AI becomes a step in the process, not a separate project.

Each chain is designed with a safety net: automatic retry, idempotency to prevent duplicates, followed by an alert to the administrator with a direct link to the incident if the failure persists. A silent failing automation is worse than no automation at all.
