Méca Industrie: orders, invoices and reminders automated with n8n

Every day the back-office team copied orders received by email into the ERP, then matched supplier invoices to purchase orders by hand. Payment reminders went out whenever someone remembered.

• Hours of data entry every day
• Quantity and price errors on orders
• No follow-up of reminders

We installed n8n on the client's infrastructure, then built the workflows together with the team:

• Orders: the email is read by an AI model, the customer is found or created, the order is recorded in the ERP and confirmed to the customer
• Supplier invoices: field extraction, matching with the purchase order, one-tap approval on mobile, then the accounting entry
• Payment reminders and a weekly report sent automatically

Every workflow is versioned, monitored and retried automatically on error. The team was trained to change simple workflows on its own.

Orders reach the ERP within minutes of the email, compliant invoices are approved in one tap and the team won back nearly one full-time position for customer follow-up.
