Odoo Online → Xero Integration using n8n (Contacts + Invoices)

@webperfection123

Hi, I can help create a reliable one-way sync using n8n to keep your contacts and invoices in sync without duplicates. To achieve this, I will set up a workflow that checks Odoo for contacts with the specified custom fields and ensures messages sync accurately. It will also address invoice syncing by ensuring there’s a corresponding contact in Xero before creating the invoice. I have 5+ years of experience with n8n, Odoo API, and Xero integration, and I’m committed to delivering a clean and documented setup. I’ll also provide instructions for running the workflow and adjusting settings as needed. Let me know if you’d like to discuss this further! Best Regards, Priyanka

Hello We have reviewed your requirement for Odoo Online → Xero integration using n8n, and this aligns perfectly with our expertise as an official Odoo partner with strong experience in ERP and API integrations. We will build a clean, one-way sync from Odoo to Xero using n8n, ensuring zero duplication and full control. Contacts will sync based on your conditions with email-based matching (update/create), and invoices will sync only when posted, with correct mapping of customer, items, taxes, and dates. We will implement duplicate prevention using sync flags and Xero Contact ID storage in Odoo. The workflow will include hourly polling, a manual “Run Now” option, and proper error logging for failed syncs. Our approach keeps the solution simple, stable, and fully compatible with Odoo Online (no custom modules), using secure API connections. We will also provide clear documentation for managing and extending the workflow. Before proceeding, we would like to confirm: Xero tax and invoice setup Odoo API access Any additional fields to sync We are confident in delivering a reliable and production-ready integration. Best regards, Ambient Infotech

Hi I can build a clean, stable one-way n8n integration from Odoo Online to Xero with strict duplicate prevention and simple long-term maintenance. The main technical challenge here is making Odoo SaaS work reliably through API polling while preserving idempotency for both contacts and posted invoices. My approach is to use Odoo Online JSON-RPC/API queries filtered by your sync flags, then apply email-based matching in Xero, create-or-update logic for contacts, and controlled invoice creation only for posted customer invoices. I have experience with n8n workflow design, Odoo integrations, API-driven accounting sync, and building error-tolerant automations that stay easy to understand and extend. To prevent duplicates, I would combine Odoo-side sync status tracking, stored Xero IDs, and conditional checks before every create action for both contacts and invoices. The workflow will include hourly polling, a manual Run Now path, structured error logging, and clear documentation for adjusting schedules or extending mapped fields later. This gives you a simple, maintainable integration that keeps Odoo as the source of truth while sending only the approved records into Xero. Thanks, Hercules

@Feriver

Hello, I understand you need a reliable Odoo Online → Xero integration via n8n for contacts and invoices, with no duplicates and full sync control. I will implement a one-way, stable workflow that: syncs only approved contacts, posts invoices, prevents duplicates via email matching, tracks sync status, and logs errors. Setup will include manual “Run Now” and hourly polling, using Odoo Online API and Xero API. Custom fields (“Sync to Xero,” “Xero Synced,” “Xero Contact ID”) will be utilized and documented. Deliverables include a fully working n8n workflow, clear instructions for manual runs, field additions, and maintenance-free stability. Thanks, Asif

@Apurva510

Hello, I have carefully reviewed your requirement for a one-way sync from Odoo Online to Xero using n8n for contacts and posted invoices with duplicate prevention and proper sync tracking. This is a clear automation workflow project, and the most important parts will be duplicate prevention, sync status tracking, and stable error handling. I have experience working with n8n automation, REST APIs, webhooks, and accounting/ERP integrations, including syncing contacts, invoices, and handling idempotent workflows to prevent duplicates. I will implement: - Contact sync from Odoo to Xero based on “Sync to Xero” and “Xero Synced” fields - Writing back Xero Contact ID and updating sync status in Odoo - Invoice sync for Posted Customer Invoices only - Hourly polling workflow + manual “Run Now” option - Error handling and failed sync logs - Clean, documented n8n workflow with instructions A quick question: Approximately how many contacts and invoices are expected per day? This helps decide the best polling and batching approach. I can deliver a clean and stable workflow that is easy to maintain and does not require custom Odoo modules. Looking forward to working with you. Thank you.

Hi, I understand that you need a reliable one-way integration from Odoo Online to Xero using n8n, syncing approved contacts and posted invoices without duplicates. My approach will be to create a clear n8n workflow that checks the custom "Sync to Xero" and "Xero Synced" fields for contacts, searches Xero by email, and updates or creates contacts accordingly. For invoices, I will ensure the customer exists in Xero before creating the invoice with accurate line items, VAT, and dates. Duplicate prevention will be handled through email matching and sync status tracking in Odoo. The workflow will include hourly polling, a manual run option, and robust error handling. I will deliver a fully documented, maintainable setup with instructions for manual execution, polling adjustment, and adding fields if needed. Pre-delivery testing will involve syncing sample contacts and invoices to verify correctness, error handling, and duplicate prevention. Best, Justin
