Company Background & Operating Scope

Multinational commercial solar contractor and electrical engineering enterprise operating across Australia, New Zealand, and Southeast Asia.

Odoo-Xero Dual Accounting Synchronization Bottleneck

The client managed CRM, engineering design, field service, and solar inventory inside Odoo ERP, but their Australian financial audit team used Xero for Australian Taxation Office (ATO) BAS compliance, payroll, and banking feeds. Double-entering thousands of monthly invoices and payment vouchers into Xero caused ledger mismatches, human clerical errors, and delayed month-end financial reporting by over 10 days.

Bi-Directional OAuth 2.0 REST API Integration Gateway

Maifelz engineered a robust bi-directional Odoo ↔ Xero REST API integration gateway with real-time webhook listeners. Confirmed invoices, bills, customer records, and tax rates in Odoo automatically replicate into Xero within milliseconds, while reconciled bank payments in Xero update invoice settlement status in Odoo instantly.
