Running payroll in the Kingdom means answering to GOSI, the Wage Protection System, Mudad, Qiwa, and the Saudi Labor Law all at once — and Odoo core payroll knows none of them. This is a build-to-order Saudi Arabia Payroll module that ECOSIRE designs, builds, installs, and supports for your specific establishment structure. It is not an instant apps.odoo.com download; it is a purpose-built localization delivered on your Odoo 17, 18, or 19 database in one working week.

At its heart is a KSA-aware payroll engine built on Odoo's HR Payroll framework (hr.payslip, hr.salary.rule, hr.contract). We add GOSI contribution logic that applies the correct Saudi-national and non-Saudi (expat) rates — including the split between employee and employer portions and the Occupational Hazards branch — as computed fields with proper @api.depends dependencies so every payslip line recalculates cleanly when contracts or salary structures change. End-of-service award (ESB) is modeled per Saudi Labor Law tenure brackets (the one-half-month and one-month tiers, resignation vs. termination handling), so final settlements are defensible, not spreadsheet-guessed.

Compliance output is first-class. The module generates the Mudad / WPS salary file in the layout your bank or the Mudad platform expects, driven by validated employee IBAN, GOSI number, and Iqama/National ID fields we add to hr.employee. Payslips, GOSI schedules, and settlement statements are produced as bilingual (Arabic/English) QWeb PDF reports that respect right-to-left rendering. Distinct expat and Saudi-national salary structures let you keep allowances, deductions, and contribution rules cleanly separated, while Nitaqat / Saudization tracking fields surface your Saudi headcount ratio directly in Odoo for workforce planning.

Everything ships as a proper Odoo addon: a clean __manifest__.py declaring dependencies (hr_payroll, hr_contract, and the KSA localization where relevant), models under models/, access control via ir.model.access.csv plus record rules so HR officers see only their company's payslips, list/form/search views in XML (with OWL components where interaction warrants), automated actions for month-end payroll reminders, and JSON-RPC/XML-RPC endpoints so your bank-integration or attendance systems can push and pull payroll data. It works on Community or Enterprise — we adapt the build to your edition and confirm compatibility with your installed localization during discovery. You get the source code, you own it, and ECOSIRE stands behind it with a support and bug-fix window after handover.
