Odoo Pos expert needed

We are looking for an experienced Odoo expert / QA Engineer to test, verify, and document our custom Odoo Point of Sale (POS) system. The system has been configured for use in Sweden, and we need to ensure that it fully complies with the Swedish Tax Agency's (Skatteverket) strict legal regulations for cash registers (including SKVFS 2014:9, 2020:10, and 2021:17). We have a specific "Declaration of Cash Register" checklist ) that details every technical requirement that must be validated. Compliance Testing: Audit the Odoo POS system against the attached Swedish compliance document chapter by chapter (Requirements, Obligatory functions, Non-permitted functions, and Receipt/Report schemas). Feature Verification: Verify that forbidden functions (e.g., deleting or modifying completed journal entries) are properly blocked. Receipt & Report Auditing: Ensure that the cash receipts, X-reports, and Z-reports include all legally required fields (such as sequential numbers, continuous ascending series, VAT breakdowns, and Control Unit numbers). Data Export Audit: Confirm that the journal memory can export data into the correct XML file format matching Skatteverket’s standard data export regulation (SKVFS 2021:16). Documentation: Complete the attached "Declaration of Cash Register" document by verifying and marking each requirement as "In place" or "Not applicable". Provide a short summary/log of your tests. Requirements: Strong expertise in Odoo POS development, configuration, and testing. Previous experience with fiscal/legal localization for European POS systems (experience with Swedish Kassalagen or connecting Odoo to CleanCash/fiscal boxes is a massive plus). Detail-oriented with a strong focus on software QA and compliance auditing.
