Summary We are a manufacturing business seeking an experienced Odoo Consultant/Developer to manage a full migration and version upgrade. We are moving from Odoo Online v18 to a self-hosted Hostinger VPS and upgrading the database to Odoo 19. Project Scope: 1. Infrastructure Setup: Provision and secure a Hostinger VPS (Ubuntu 24.04 preferred) with Python 3.12 and PostgreSQL 16. 2. Migration & Upgrade: Export Odoo 18 Online data and perform a successful upgrade to Odoo 19 (Stable). 3. Custom App Audit: Ensure our simple custom-built app and its Studio-based logic (conditional tabs, Many2many relations) function perfectly in the v19 UI. 4. Xero Integration: Deploy and configure a robust Odoo-Xero integration. Note: We have existing historical data in Xero and CRM leads in Odoo. You must handle the contact mapping and historical invoice linking to prevent duplication and ensure clean analytics. 5. Optimization: Performance tuning for the Odoo 19 ORM on VPS and setting up Nginx with SSL. Requirements: - Proven experience with Odoo 18 to 19 migrations. - Expertise in PostgreSQL 16 and Python environment management on VPS. - Deep understanding of Odoo-Xero connectors and data reconciliation strategies. - Experience with Odoo Studio and custom module troubleshooting. - Ability to complete this project within a 2-week timeline. To Apply: Please outline your experience with Odoo 19 specifically and your strategy for linking historical Xero invoices to existing Odoo CRM opportunities without creating duplicates. Screening Question: Which Odoo-Xero connector do you recommend for Odoo 19, and how do you handle webhook failures?
