Payroll is where Odoo Community runs out of road fastest. The full salary-rule engine — salary structures, rule categories, computed lines, and batch payslip generation — ships only with Enterprise, so Community teams end up exporting hours to spreadsheets, hand-calculating gross-to-net, and re-keying the result back as journal entries. The pain is not just the manual time; it is the audit gap. Nobody can point at a single record and explain how a net figure was derived, and every policy change means editing formulas in a workbook nobody version-controls.

We build a payroll module that lives natively inside your Odoo Community database. At its core is an hr.payslip model with computed hr.payslip.line records driven by a configurable set of salary rules — each rule carries a Python amount_python_compute expression (or a fixed/percentage code path) evaluated against contract, employee, worked-days, and inputs, exactly the mental model an Enterprise-experienced HR lead already has. Rules resolve in sequence, feed rule categories (Basic, Allowance, Deduction, Gross, Net) through @api.depends compute chains, and the totals lock into a slip that is an immutable derivation rather than a spreadsheet snapshot. Contracts (hr.contract) hold wage, schedule, and the assigned salary structure; a payslip batch (hr.payslip.run) generates a whole period's slips in one action.

Around that engine we build what makes payroll usable day to day: QWeb payslip PDFs on your letterhead, an accounting bridge that posts each confirmed slip to a configurable account.move mapping (so gross, deductions, and employer contributions hit the right ledgers), and the security layer — ir.model.access.csv plus record rules so a line manager sees only their team's slips while payroll admins see the batch. Employee self-service payslip access, automated actions for period reminders, and an XML-RPC/JSON-RPC surface for pushing bank-file exports or pulling figures into your BI all sit on top. Everything is delivered as a proper Odoo module with a versioned __manifest__.py, so it upgrades cleanly rather than living as untracked studio tweaks.

Because this is build-to-order, we start from your actual policy — your salary components, your statutory deductions, your pay calendar — not a generic template. After a short scoping call we confirm the salary-rule catalogue, the report layout, and any localization (income-tax slabs, social-security, end-of-service) in writing, build against a staging copy of your database, and run UAT with your team before go-live. Typical delivery is 2–4 weeks from confirmed scope. Pricing starts from $249 (indicative, single-company base scope); localization depth, statutory reporting, multi-company payroll, and historical payslip data migration increase the quoted scope. You receive a fixed quote after the scoping call — never a surprise.
