Worked on the brain-tec/odoo repository to enhance localization accuracy for the Canary Islands tax module in Odoo version 18. Focused on data management and tax compliance, the developer addressed a critical bug by updating tax field naming to match the new version’s requirements, ensuring correct tax calculations and regulatory alignment. The solution involved careful adjustment of CSV-based configuration data, specifically resolving a mismatch in the price_include field that previously posed a compliance risk. This targeted fix demonstrated a methodical approach to maintaining localization modules, providing a clean, auditable change that supports ongoing readiness for Odoo 18.x regulatory updates.
