Developed billing currency support for the SupplierUpdateMaster module, introducing a billing_currency field to the Python data model within the Gurukrupa-Export/gke_customization repository. This enhancement enabled the specification of a default billing currency, streamlining multi-currency billing scenarios and reducing manual configuration errors. The work focused on backend development using Python and object-oriented data modeling, with all changes versioned through Git. By extending the data model, the update improved financial data integrity and scalability for global customers, laying the groundwork for future currency localization. No major bugs were reported during this period, reflecting a focused and stable implementation process.
