Odoo Employee Self Service Mobile App: Options, Build Paths, Cost

Most employees never open an ERP at a desk. They want to request leave, clock in, claim a taxi fare and read a payslip on a phone. As an Odoo development company, we build that layer, and the first step is often no code at all.

This guide is for HR heads, operations leads and IT managers on Odoo 19 or Odoo 20 who are weighing an Odoo HR mobile app. If payroll itself is not configured yet, start with our Odoo payroll setup guide.

What is an Odoo employee self service mobile app?

An Odoo employee self service mobile app is any phone screen that lets staff handle their own HR tasks in Odoo without calling HR. It is a use case, not one product you install.

The four jobs are the same in almost every company: request time off, record attendance, submit expenses and read payslips. Managers add a fifth job, which is approving those requests.

The term covers three different things. It can mean Odoo's own mobile app, a customized Odoo employee portal, or a separate employee self service app built on the Odoo API. Each has a different cost, license impact and upgrade risk.

Does Odoo have a mobile app for employees?

Yes, Odoo has a mobile app for employees in two forms: a progressive web app (PWA) and store apps for Android and iOS. Neither is a separate HR product; both open the same Odoo database on a phone.

Odoo's mobile apps documentation says "Using the PWA is recommended." The PWA adds a home screen icon, push notifications and SSO sign-in. The store apps support several accounts but are not compatible with SSO.

Both need a login. An employee with no Odoo user cannot use the Odoo mobile app at all, which is why licensing decides most of this project. We cover it below.

How do leave requests work with Odoo Time Off on a phone?

With Odoo Time Off, an employee opens the app, picks a leave type and dates, and submits the request to an approver. The same form works in the mobile app because it is the standard Odoo screen.

Odoo's guide to requesting time off lists the fields: time off type, dates, a description and, where the type requires it, one attached file such as a doctor's note.

Two details reduce HR calls. If the type needs no approval, the request is approved automatically. If an employee asks for more days than they have, the form warns "Only (#.#) day(s) available" before they submit.

Approval goes to the employee's manager or the time off officer. Under Odoo 20 licensing, the person who approves leave needs a full user, a point many rollout plans miss.

How does the Odoo attendance app work on mobile?

The Odoo attendance app offers two phone-friendly paths: a personal check-in button for staff with a login, and a shared kiosk for staff without one. Pick per workforce group, not per company.

Personal check-in for logged-in users

Users check in from an attendance icon in the top bar of any Odoo screen. Odoo's check in and out documentation says the app logs the IP address and GPS coordinates, but only if the user grants location permission.

The documentation describes logging a location, not blocking by location. If you need a rule such as "check in only within the site," plan it as custom work and test it on real phones.

Kiosk mode for staff without a login

Odoo's attendance kiosk documentation defines a kiosk as a dedicated PC, tablet or mobile phone. Staff identify themselves by manual selection, a barcode badge or RFID token, with an optional PIN.

One caution from the same page: kiosk URLs are not secured with an access code, so anyone with the URL can open the kiosk. Keep the device on site and generate a new URL if it leaks.

How do employees submit claims in the Odoo Expenses app from a phone?

In the Odoo Expenses app, an employee can type an expense, upload a receipt, or email the receipt to an expense address. A phone camera makes the upload and email routes the natural ones.

Odoo's log expenses documentation lists four ways to create an expense: manual entry, receipt upload, drag and drop, and email to an alias such as expense@yourdomain.

• Receipt scanning: the Expense Digitization (OCR) setting reads the receipt and fills the record, and it needs in-app purchase credits.
• Email route: Odoo only accepts emails sent from the work email saved on the employee record.
• Reinvoicing: an expense can point to a sales order, so the customer is billed for it later.
• Analytics: each expense can be split across projects or departments.

Plan for weak signal. Odoo's offline mode documentation calls it a solution for short interruptions, and says attachments cannot be uploaded while offline. A receipt photo needs a connection.

How do employees get an Odoo payslip on mobile?

Employees get an Odoo payslip on mobile mainly as a PDF sent by email after the pay run. Odoo's pricing page also lists getting payslips among the things a Light User can do.

In Odoo 19, a payroll officer clicks Send By Email on a validated payslip. Our Odoo 20 payroll release notes show a new setting that sends payslips when confirmed, when paid, or manually.

Email reaches every phone, but it is not a payslip archive. If staff must browse past payslips inside an app, test what your version shows a Light User before you pay for a custom screen. Payroll data is the most sensitive data in this project.

What does Odoo employee self service cost in licenses?

Odoo employee self service costs US$8.90 per employee a month in the US on Odoo 20, because every active employee is billed as a Light User. In India the price is Rs 195 and in Europe EUR 7.90.

Odoo's subscription agreement defines a Light User as a login set to the Light role, or any active employee record not linked to an active non-portal user. The Odoo pricing page lists the prices; Light Users are quoted by an Odoo Advisor.

This changes the old advice. Building an Odoo employee portal to avoid user fees no longer works for your own staff, since the employee record is billed anyway. Our Odoo 20 Light User guide explains the rules and worked examples.

The useful side: if the record is billed either way, a Light login adds self-service at no extra license cost. Confirm your own quote with Odoo, because one extra access right turns a Light User into a full user.

Which build option fits an Odoo employee self service mobile app?

Five build options fit an Odoo employee self service mobile app, and they run from zero code to a full custom app. Start at the top of the table and move down only when a real gap forces you.

Hosting limits the lower rows. Odoo states that Odoo Online is incompatible with custom modules and Odoo Apps Store modules. A custom portal therefore means Odoo.sh or your own servers.

Unsure where your gap sits between Studio and code? Our comparison of Odoo Studio vs custom development gives the decision rules.

When is custom Odoo mobile app development worth it?

Custom Odoo mobile app development is worth it when the standard Odoo mobile app cannot meet a need that matters every day. A logo on the home screen alone is rarely enough reason.

• Device features: site-radius check-in, selfie attendance or biometric unlock that standard screens do not offer.
• Very simple screens: a workforce that needs three large buttons in a local language, not Odoo menus.
• One app for everything: HR tasks beside rosters, safety forms or company news from other systems.
• Long offline work: crews in the field for hours, beyond the short interruptions Odoo's offline mode covers.

A custom app reads and writes Odoo through the external JSON-2 API, added in Odoo 19. Odoo says external API access is only available on Custom pricing plans, so budget the plan change for all full users.

Build on JSON-2, not the old protocols. XML-RPC and JSON-RPC are deprecated in Odoo 20 and scheduled for removal in Odoo 22. Our guide to moving XML-RPC integrations to the JSON-2 API covers the change.

Each employee should sign in as themselves with their own API key, so Odoo's access rules still decide what they see. One shared admin key for all staff is the mistake to avoid. See our Odoo API integration guide for patterns.

What changes between Odoo 19 and Odoo 20 for an Odoo HR mobile app?

Between Odoo 19 and Odoo 20, the screens for an Odoo HR mobile app stay similar, but licensing, payslip sending and the API rules change. Check these five points before you plan.

If you are on Odoo 19 and plan a custom app, write it against JSON-2 now. The app then survives the upgrade to Odoo 20 without a rewrite of its connection layer.

Which industries need an employee self service app most?

Industries with many staff away from desks gain the most from an employee self service app. The table shows the usual pain and the Odoo approach we would test first.

How do you roll out employee self service in Odoo?

Roll out employee self service in Odoo in small steps, starting with one task and one pilot group. Most failed rollouts try to launch every HR task on day one.

1. Clean employee records: work email, manager, time off approver and PIN for every active employee.
2. Sort people into groups: Light login, kiosk only, or full user for approvers and HR.
3. Configure the apps: leave types, attendance rules, expense categories and the payslip sending rule.
4. Install the PWA: give staff a one-page guide with screenshots for Android and iOS.
5. Pilot one team: run leave requests alone for two weeks, then add attendance and expenses.
6. List the gaps: write down what staff could not do, and price only those items as custom work.

Our published range for a small Odoo implementation is $3k to $9k over 4 to 8 weeks, and a standard HR self-service rollout often fits there. Custom apps are quoted after scoping, so use the Odoo project estimate tool for a first range.

Odoo employee self service mobile app case study: Enabl Health

An Australian health-tech company needed portal users to do their own work on a phone, and we rebuilt two Odoo portals mobile-first. The users were doctors and patients, not employees, but the self-service pattern is the same.

Enabl Health tracked work hours with manual start and stop times. Its doctor and patient portals were not mobile-friendly on Android or iOS, and portal users could not edit timesheets or upload attachments.

We extended Odoo's Timesheet, Payroll and Portal layers. The work included role-based portal views, fully responsive layouts for Android and iOS, editable timesheet entries and document uploads inside the portal.

The project ran 10 weeks on Odoo.sh with separate staging and production branches. Doctors and patients now self-serve on mobile. Read the Enabl Health timesheet and portal case study.

The bottom line on an Odoo employee self service mobile app

Start with the standard Odoo mobile app and Light Users, add kiosks for staff without logins, and build custom only for gaps you have seen in a pilot. That order keeps cost and upgrade risk low.

In Odoo 20 the license question is mostly settled, since employee records are billed with or without a login. The real choices are which screens staff use and whether any gap justifies custom code.
