Payroll Engine Pro - Payroll for Odoo Community
A real, fully configurable payroll calculation engine on top of Odoo HR - no Enterprise dependency
You define the salary structures, rules, allowances and deductions; the engine computes payslips, batches and PDFs. Community Odoo ships HR but no payroll computation - this adds it.
The problem & who it's for
Odoo Community gives you the HR app - employees, contracts, leaves - but the payroll computation engine is Enterprise-only. Small businesses, accountants and HR teams on Community are left running payroll in spreadsheets. Payroll Engine Pro closes that gap with a generic, framework-free computation engine. It is not a country pack: it does not encode any country's statutory tax or social-security rates. Instead you model your own policy with salary structures and rules, and the engine does the maths - repeatably, transparently and unit-tested.
Key features
Configurable salary structures
Build ordered sets of salary rules and assign a structure to a payslip. Rules apply in sequence, so later rules can reference the running totals built by earlier ones.
Flexible salary rules
Fixed amounts, percentage-of-base, quantity × rate, or safe Python expressions - with optional conditions (always, base-in-range, or Python). Rules compute against configurable bases: BASIC, GROSS, TAXABLE, earlier rule codes or custom accumulators.
Rule categories
Classify every rule as Basic, Allowance, Deduction, Gross or Net so the engine knows how it contributes to gross, total deductions and net.
Payslips with line detail
One line per applied rule, with gross, total deductions and net computed for each employee - and a clean QWeb PDF payslip ready to print or email.
Payslip batches
Generate and compute payslips for many employees in one run - ideal for monthly payroll across a whole department or company.
Free-form inputs
Feed overtime hours, bonuses and other per-payslip inputs straight into your rules, so the same structure adapts to each employee's month.
Safe expression evaluation
Python conditions and amounts run through a restricted evaluator - administrators write the formulas they need without ever exposing arbitrary code execution.
Unit-tested computation core
The maths lives in a framework-free, fully unit-tested pure function using Decimal money and round-half-up to two decimals - so payslip totals are precise and reproducible.
How it works
- Define rule categories (Basic, Allowance, Deduction, Gross, Net).
- Create salary rules - fixed, percentage, quantity × rate or Python - against the bases you choose.
- Assemble a salary structure from those rules in the order they should apply.
- Generate payslips for one employee or a whole batch, add any free-form inputs, and compute.
- Print or email the PDF payslip with full per-rule line detail.
Why this module
Odoo's payslip computation engine is an Enterprise feature. Payroll Engine Pro brings an
equivalent, fully configurable engine to Odoo Community payroll - depending only on
hr and mail. Because it is policy-neutral, it works in any country and any
pay model: you stay in full control of every rule, and nothing is hard-coded behind your back.
