Build an API between Odoo Online and Xero for Bills and Invoices - where Odoo sends data to Xero

@ambar

Hello, I’ve reviewed your attached requirements and field mappings in detail. This is a straightforward Odoo Online v19 → Xero push integration, with Odoo as the master, and I’m comfortable with this setup. My approach will be simple and controlled: • Odoo sends Bills and Invoices to Xero once per day (10:00pm AEST), with an option for manual trigger • No historical data — only new or updated records after deployment • Records sync independently, so one failure never blocks others • Clear error report generated on each run Contacts will be handled exactly as specified: • Match by ABN first, otherwise by Name • Create in Xero only when required • No duplicate contact creation Bills and Invoices will follow your mapping strictly: • Odoo invoice number overrides Xero • GST mapping via a small translation table • AUD currency, tax-exclusive amounts • No attachments, analytics, branding, or journals sent This will be built using Odoo Online’s external API and Xero’s API, keeping the integration lightweight and easy to maintain. I work as an individual freelancer, hands-on with both Odoo and Xero integrations (including AU GST setups). I focus on getting exactly what’s required running cleanly, without unnecessary complexity. Happy to proceed once you’re comfortable with the plan.

Hello, I am a strong fit for this Odoo Online (v19) → Xero integration with 11+ years of experience building accounting and ERP integrations where data integrity, mapping accuracy, and fault tolerance are critical. I have hands-on experience working with Xero APIs and Odoo Online constraints (no custom server-side modules), designing reliable outbound sync processes. Key areas I would handle confidently: One-way sync (Odoo as master) for Bills and Invoices with scheduled and manual runs Contact matching logic using ABN-first, then Name fallback Precise field mapping, tax translation rules, and invoice number override in Xero I’m experienced in building idempotent, non-blocking sync jobs with retry logic, per-record error handling, and detailed error reporting files. I understand Australian accounting requirements (GST, BAS Excluded, GST Free) and how to correctly map Odoo tax configurations to Xero tax rates without breaking reconciliation. I have delivered integrations starting from clean-slate design through production rollout and ongoing stability, including nightly batch syncs, auditability, and safe failure handling. I communicate clearly, follow structured workflows, and prioritize accuracy over shortcuts—especially for financial data. I’m confident managing this integration from design to deployment and long-term reliability.

Hello, I will build a reliable API connection between Odoo Online and your external system in a simple and clean way. I can map the data you need, handle secure authentication and make sure syncing works smoothly without duplicates or missing records. I will start by reviewing your Odoo Online model needs and the target API. Then I will design the sync flow, including create, update and status tracking, with proper error handling, retries and clear logs. I will also implement field mapping and validation so the data stays clean and set up webhook or scheduled sync depending on what fits best. We can confirm the exact endpoints, sync direction and frequency, then plan milestones that match the scope. I will deliver a neat codebase with documentation, test cases for key endpoints, and a short guide on how to run and maintain the integration. Looking forward to discussing further.

@Appworldz

Hi, Odoo Online will remain your single source of truth while a robust, one‑way API pushes new and updated Bills and Invoices into Xero with the exact field mappings and tax rules defined in your BRD for AU compliance. My team has hands‑on experience with Odoo Online v19 and Xero APIs, and will implement: Nightly (22:00 AEST) scheduled sync with optional manual trigger, handling only post‑go‑live records, plus retry and error‑logging as described in your requirements. Contact matching by ABN and Name, strict Bills/Invoices header and line‑item mapping (accounts, tax codes, quantities, discounts) so Xero documents mirror Odoo documents while preserving Xero’s own numbering rules where required. Estimated effort is 15 days end‑to‑end, including development, test against your sandbox, and UAT support, at around 900–1,200 USD depending on access and environments. Would you prefer a purely scheduled overnight sync, or do you also need an on‑demand “sync now” option from Odoo when finance closes the day ? Regards Sahanaj

@muhammadu134

Hi, How do you want to handle document lifecycle events—updates, cancellations, and deletions—in Xero once a Bill or Invoice is modified or voided in Odoo, and should Xero ever be allowed to change status independently? Can you confirm the exact GST handling expectations, including zero-rated, GST-free, and mixed-tax line items, and how rounding differences between Odoo and Xero should be resolved to avoid reconciliation issues? What should be the unique matching keys for Contacts, Bills, and Invoices between Odoo and Xero (e.g., Odoo ID, document number, external reference), and how should the integration behave when duplicates or conflicts are detected? I will implement a secure bi-directional API integration using Odoo Online’s native REST API and Xero’s Accounting API, with Odoo as the single source of truth for all Bills and Invoices. The solution will strictly follow the provided field mappings and Australian GST rules, handling contacts, tax codes, line items, and document status with automated validation and error logging. The integration will be lightweight, maintainable, and fully compliant with Odoo Online constraints (no custom modules), using token-based authentication and scheduled sync jobs for reliability. Let's have a chat to discuss further. Thanks
