Payroll that closes the month, not just prints payslips
Contracts, work entries, statutory contributions and personal income tax in one engine - so a payslip shows gross, every deduction, the employer's own cost, and a net figure you can defend line by line.
Payroll (technical name to_hr_payroll) is an Odoo 19.0 app for Odoo Community and Odoo Enterprise and Viindoo Cloud, built for payroll officer, hr manager, accountant, employee.
At a Glance
The facts of Payroll, version 1.5.6, in one place. Published by Viindoo.
Key Features
This is the payroll engine behind Viindoo HR: salary structures and rules you can read and change, contribution registers per employee for each statutory scheme, a personal income tax table with its own deductions, and a monthly batch that takes a whole company from work entries to validated payslips. It is built for payroll that has to survive an audit - every amount on a payslip traces back to a rule, a register or a work entry, and the employer's share is computed and reported beside the employee's.
Contribution history, not just a rate
Every change to a contribution base or rate is written as a dated history line. When an inspector asks why March deducted a different amount from April, the answer is a record, not a memory.
Personal income tax with its own table
Progressive brackets and the deductions that apply are configuration, not code. Withholding commitments are recorded for the employees entitled to them.
Reports on validated payroll
Payroll, contributions and income tax each have their own analysis view, filtered by default to payslips that are waiting or done, so a draft month never inflates a report.
Allowances as templates
Travel, phone, meal, responsibility and attendance allowances are templates you attach to a contract or a job, instead of a rule rewritten per employee.
How It Works
Five steps from an employment contract to payslips a payroll officer can defend, on real data.
Put the contract on a salary structure
A contract carries a wage, a salary computation mode - by day or by hour - and the salary structure that decides which rules run. Without that structure the payslip has nothing to compute, so this is the first thing to get right for each contract.
Open a contribution register for each scheme
Social insurance, health insurance, unemployment insurance, union dues - each one is a register on the employee, with the base the contribution is computed on and both rates. Confirming a register writes a history entry, and it is that history the payslip reads, so the deduction on a payslip can always be traced to the base that applied in that month.
Bring the work entries in and validate them
Work entries come from the working schedule, from time off, and - with the attendance apps - from the clock on the wall. Validate them before you generate: the payslip's worked-days lines are what the Basic rule multiplies, and a payslip generated before its work entries exist stays empty.
Compute the batch and read the payslip
The batch computes every payslip at once and shows basic wage, gross, net and company cost per employee, with column totals. Each payslip breaks the same figures down: gross, the employee's four contributions, the employer's own contributions, the tax base after deductions, the income tax, and the net.
Verify, send, and report
Payslips move Draft to Waiting to Done, so a month can be reviewed before it is closed. Once validated, the payroll analysis, the contribution analysis and the personal income tax analysis report on the same records - no export, no second spreadsheet.
What You Get
Salary structures made of ordered rules, each with its own condition and Python or fixed amount, grouped in categories that roll up to Basic, Gross, Taxable base and Net
A contribution register per employee per scheme, with its own base, employee rate and company rate, and a history of every change to the base - which is what a social-insurance inspection actually asks for
Personal income tax computed from a bracket table with the deductions the employee is entitled to, kept as its own record so the tax base is auditable
Monthly batches: generate for every running contract, check for duplicate payslips, compute the batch, verify, then send the payslips by email
Work entries drive the amounts: a payslip warns when its work entries are missing, unvalidated or in conflict, before you compute
Thirteenth-month pay, refunds and salary cycles with an offset, for companies whose payroll month is not the calendar month

What This App Does Not Do
Read this before you buy. Everything below is something the app deliberately leaves to another app or to you.
The engine, the tax table and the contribution registers are here; the rates, brackets and rules for your country are configuration. Viindoo publishes a Vietnamese package on top of this app; other countries are yours to set up or ours to build with you.
Salary journal entries come from the payroll accounting app, which builds on this one.
Work entries can come from the working schedule and time off out of the box. Attendance machines, timesheets and overtime each have their own app that feeds work entries into this one.
It pays for the time that was worked and approved; deciding who works when is planning, and lives elsewhere.
It stays at zero rather than guessing. Check the structure on the contract before running the month - and see the readiness note in our documentation.
A contribution history line with no end date is not yet in the analysis report; the register list and the history list show it from day one.
Who Should Use Payroll?
Payroll officer
Runs the month: generates the batch, resolves work-entry warnings, computes, verifies, and sends payslips.
HR manager
Keeps contracts, salary structures and contribution registers in step with reality - hires, raises, suspensions.
Accountant
Reads the payroll analysis and the contribution reports, and posts the salary journal (with the payroll accounting app).
Employee
Receives the payslip by email and sees the same gross, deductions and net that HR sees.
Frequently Asked Questions
What does Payroll do?
Contracts, work entries, statutory contributions and personal income tax in one engine - so a payslip shows gross, every deduction, the employer's own cost, and a net figure you can defend line by line.
What does Payroll not do?
It does not ship a country's rules ready-made. The engine, the tax table and the contribution registers are here; the rates, brackets and rules for your country are configuration. Viindoo publishes a Vietnamese package on top of this app; other countries are yours to set up or ours to build with you. It does not post to the general ledger on its own. Salary journal entries come from the payroll accounting app, which builds on this one. It does not read your clocks by itself. Work entries can come from the working schedule and time off out of the box. Attendance machines, timesheets and overtime each have their own app that feeds work entries into this one. It does not plan shifts. It pays for the time that was worked and approved; deciding who works when is planning, and lives elsewhere. A payslip whose contract has no salary structure computes to nothing. It stays at zero rather than guessing. Check the structure on the contract before running the month - and see the readiness note in our documentation. Contribution analysis counts closed contribution periods. A contribution history line with no end date is not yet in the analysis report; the register list and the history list show it from day one.
Who is Payroll for?

Technical Requirement
Changes log
1.5.5 - Latest on the 17.0 line
- Contribution registers keep a full history of base and rate changes, and payslips read the history rather than the current value.
- Work-entry warnings on the payslip: missing, unvalidated and conflicting entries are flagged before you compute.
- Duplicate-payslip check on the batch, so a month cannot be generated twice by accident.
- Thirteenth-month pay computed from the year's average, with its own salary structure.
2025-2026 - Performance on real payrolls
- Batch computation reworked to avoid recomputing fields that did not change.
- Payslip line deletion moved to a single statement, which is what made large batches slow.
- Contribution and tax analysis views read from stored fields instead of recomputing per row.
Installation
- Navigate to Apps;
- Search with keyword to_hr_payroll;
- Press Install.

1. Initial configurations for payroll
- Salary cycle: The salary cycle of the business. The default will be from the beginning to the end of the current month. You can create a new one in case your company has a different Salary cycle. Example: Salary cycle from the 25th of this month to the next 25th.
- Salary Structure: A salary structure is a set of rules used to determine how much employees will be paid. The system allows the creation of many salary structures such as salary structure for the office department, salary structure for the production department, etc.
- Salary rule: Salary rules are also understood as calculation formulas for items on payslips. The system has automatically added a set of basic salary rules.
- Personal tax rule: Rules for calculating Personal Income Tax.
A personal tax rule now also carries a Withholding Regime: either Standard Payroll (the rule is selected from the employee's contract, as before) or Detached Payment - a flat rate applied to income paid once none of the employee's labour contracts is in force any more, for example a payment settled after the contract has ended. A Detached Payment rule also has a Withholding Threshold per Payment and an Effective Period (start and end date) - both are plain data on the rule itself, so the rate, the threshold, or the effective date can be corrected at any time without a new release.
This module ships no Detached Payment rule for any country by itself, so nothing changes for any company until someone configures one. Only one Detached Payment rule can be in force per country at a time: saving a second one whose effective period overlaps the first is refused with an error naming the existing rule. To schedule a rate change ahead of a fixed date, set the outgoing rule's end date, then create the incoming rule starting the next day - consecutive, non-overlapping rules are allowed on purpose.
- HR Advantage Templates: Allowances for employees according to company policy. For example Harmful Subsidies, Hard Working Award, Performance Award, etc.
- Payroll Contribution Register: Deductions from salaries of Employees and Enterprises.
- Contribution Registers/Contribution Register Category: Helps to classify contributions by entities involved in salary formation such as Employees, insurance agencies, unions, etc.
2. Set up information on employee contract
After completing the configuration in step 1, you need to set this information on the employee contract:
Go to Payroll ‣ Employees ‣ Contracts, create a new employee contract:
3. Create Payslips Batches & Payslips
Go to Payroll ‣ Payslips ‣ Payslips to create payslips for each employee:
Every payslip now carries a Payment Date - the date the income is actually disbursed, not the payslip period - because that is the date that decides which tax rule applies. It defaults from the payslip batch's end date or from the payslip's own period, and can be edited by hand. If, on the Payment Date, none of the employee's labour contracts is in force any more, the payslip is marked Detached Payment. Nothing changes for a payslip whose contract is still open on the Payment Date - it is taxed on the progressive table exactly as before.
The withholding threshold is checked per PAYMENT EVENT, not per payslip: every payslip paid to the same employee, in the same company, on the same Payment Date is added together and compared with the threshold. If the total reaches it, every payslip in that group is withheld - splitting one payment into several payslips dated the same day does not avoid withholding.
On the Personal Income Tax tab, the Withholding Reason field explains in plain language why a payslip is taxed the way it is, in this order:
- a tax rule picked by hand (Tax Rule Set Manually ticked) always wins;
- otherwise, a labour contract still in force on the Payment Date is used, as before;
- otherwise, a confirmed withholding commitment (see below) blocks withholding entirely;
- otherwise, the payment is withheld once it reaches the threshold, or when the employee explicitly asked for it (Withholding Requested ticked) even below the threshold.
To pick the tax rule for one payslip by hand, tick Tax Rule Set Manually: the automatic selection then stops overwriting the Personal Income Tax Policy and the Tax Rule on that payslip, including every time Compute Sheet is clicked again. Untick it to hand the choice back to the system. A duplicated payslip never inherits this override, so review the tax rule on any duplicate.
Warning
Severance pay is fully tax-exempt by law once a labour contract ends. If it is entered as ordinary income, this feature will withhold tax on it at the country's configured Detached Payment rate - the opposite of what the law requires, and a compliance risk. Record any such allowance through the Allowance (tax exemption) category (technical code ALWNOTAX) instead of ordinary income, so it is excluded from the taxable base before withholding is even considered.
Or go to Payroll ‣ Payslips ‣ Payslips Batches to create payslips batches for departments or the company:
4. View analysis report
Go to Payroll ‣ Reports ‣ Payroll Analysis to view payroll analysis report:.
Go to Payroll ‣ Reports ‣ Payroll Contribution History to see analysis of payroll contribution history::
Go to Payroll ‣ Reports ‣ Payslip Personal Income Tax Analysis to view Personal Income Tax Analysis Report:
5. Register a personal tax withholding commitment
An employee who expects their taxable income for the year to stay under the threshold can file a written commitment asking not to be withheld on detached payments for that tax year. Go to Payroll ‣ Configuration ‣ Withholding Commitments, click New, select the Employee and the Tax Year, then click Confirm. Only a Confirmed commitment blocks withholding - a Draft or Cancelled one has no effect, and withholding proceeds as usual.
