How to connect an ERP and CRM with n8n

Define the source of truth for each field and avoid bidirectional sync without conflict rules. Test updates, duplicates and deletions before launch.

Useful automation starts by understanding the real work, before choosing a tool. This guide helps you make that decision with data, tests and clear ownership.

Where it fits your workflow

We connect existing tools through APIs or custom processes, with logs and error handling. We design reliable data exchange so teams do not repeat data entry.

How to plan the implementation

Choose the source of truth for each field. Document formats, permissions and conflict rules before syncing two applications in production.

Before implementation, map the source data, the expected outcome and the person who approves exceptions. Check which systems offer an API and which steps need manual review.

A practical example

If the ERP owns invoicing and the CRM owns opportunities, sync only the fields each team needs. Define what happens if a customer name changes in both systems on the same day. Test duplicates, missing identifiers and retrospective corrections before launch.

What to measure and when to step in

Set a baseline and monitor duplicate records, sync errors and data freshness. An automatic outcome is not necessarily a correct one: keep uncertain cases visible and record staff corrections.

Detect conflicts, schema changes and stale records; a run that finishes without errors may still write incorrect data.

CRM and ERP integration

We connect CRM and ERP to share customers, opportunities, orders or invoices without re-entering data. We define which system owns each field and how conflicts are resolved.

What comes next?

Choose one workflow, document how it works today and note the time it takes and common errors. With that baseline, we can define a small test before expanding the automation.
