Automated Shopify Order to Xero Invoice Sync (n8n)

Eliminate manual bookkeeping by automatically syncing Shopify orders and line items to Xero via n8n's robust workflow engine.

Tools: Shopify → Xero

Platform: n8n

Short Answer

A self-hosted or cloud-based n8n workflow that triggers on every New Order, validates customer data, handles multi-line items via expressions, and generates a formatted invoice and payment record in Xero instantly.

The Problem

Manual entry of e-commerce sales into accounting software is time-consuming and prone to human error. Discrepancies between Shopify revenue and Xero ledger often lead to reconciliation nightmares during tax season and inaccurate financial reporting.

The Outcome

A self-hosted or cloud-based n8n workflow that triggers on every New Order, validates customer data, handles multi-line items via expressions, and generates a formatted invoice and payment record in Xero instantly.

Step-by-Step Guide

1. **Create Workflow**: In n8n, create a new workflow and add the 'Shopify Trigger' node. Set the event to 'Order Created'. 2. **Configure Credentials**: Select 'Shopify API' credentials. You will need your Shopify Store Name and an Admin API access token (configured in Shopify Apps > Develop Apps). 3. **Identify/Create Contact**: Add a 'Xero' node. Choose the 'Contact' resource and 'Get or Create' operation. Use an expression to map `{{ $json.customer.email }}` from Shopify to the 'Email Address' field in Xero to prevent duplicates. 4. **Handle Line Items**: Use a 'Code' node or 'Set' node with the 'Line Items' array from Shopify. n8n treats arrays as separate items; use an expression like `{{ $json.line_items.map(item => ({ Description: item.name, UnitAmount: item.price, Quantity: item.quantity })) }}` to format them for Xero's API. 5. **Format Dates & Currency**: Use the n8n expression `$now` or Shopify's `created_at` field. Ensure the date format is `YYYY-MM-DD` using the `.format('YYYY-MM-DD')` JavaScript method within the expression. 6. **Create Invoice**: Add another 'Xero' node. Set Resource to 'Invoice' and Operation to 'Create'. Map the Contact ID from Step 3 and the line items from Step 4. Set 'Status' to 'AUTHORISED' for immediate ledger impact. 7. **Log Payment**: Add a final 'Xero' node. Resource: 'Payment', Operation: 'Create'. Link this to the Invoice ID generated in Step 6 to mark the invoice as paid. 8. **Implement Error Handling**: Create an 'Error Trigger' node. Connect it to a 'Gmail' or 'Slack' node to notify you if an API limit is hit or if a tax rate is missing. 9. **Test Workflow**: Click 'Execute Workflow' and place a test order in Shopify (in Bogus Gateway mode) to verify data flow in n8n's execution log.
