Affordable Custom HR System for Hong Kong SMEs

Many Hong Kong SMEs still run HR on spreadsheets instead of a proper HR system — not because they want to, but because off-the-shelf HR software is either too expensive or doesn’t fit how they actually work. Finding an HR system Hong Kong businesses can genuinely afford is harder than it should be: enterprise suites are priced for hundreds of staff, and generic SaaS tools force you into someone else’s workflow. The good news is that a customised HR management system is now more affordable than ever, even for businesses with 20–100 staff. It is also the natural place to start: HR and payroll are configuration rather than custom development, which is why the entry configuration begins at around HK$500 a month.

Why Spreadsheets Are Costing You

Relying on Excel for employee records, leave tracking, and payroll calculations creates hidden costs: manual data entry errors, time wasted on repetitive tasks, and compliance risks when MPF or tax calculations go wrong. A dedicated HR system eliminates these issues at a fraction of the cost of hiring additional administrative staff.

What a Custom HR System Includes

Built on Odoo 19 Community Edition and installed on a machine in your own office, the system is tailored to your specific workflows — not the other way around. Core modules include:

• Employee Records — Centralised database for all staff information, contracts, documents, and emergency contacts. Secure and access-controlled.
• Leave Management — Online leave applications with automated approval workflows. Supports annual leave, sick leave, casual leave, and statutory holidays in line with Hong Kong’s Employment Ordinance.
• Attendance & Time Tracking — Integration with fingerprint, face recognition, or mobile打卡 (clock-in) systems. Automatic calculation of late arrivals, early departures, and overtime.
• Payroll Processing — Auto-calculate salaries, MPF contributions, tax deductions, and statutory holiday pay. Generate payslips and submit directly to MPF trustees and IRD.
• Reports & Analytics — Customizable reports on headcount, turnover, attendance patterns, and payroll costs. Export-ready for management reviews.

HR System Hong Kong: Leave, Attendance & MPF

Hong Kong’s employment rules are specific, and generic HR software rarely handles them out of the box. A custom HR system Hong Kong businesses rely on is built around the local statutory framework instead of forcing you into workarounds.

Leave and statutory holidays

Annual leave, sick leave, maternity and paternity leave, and the 17 public holidays are tracked automatically, with balances accruing under the Employment Ordinance rather than a spreadsheet formula someone has to remember to update.

Attendance and time tracking

Clock-in data from fingerprint, face-recognition or mobile devices feeds straight into timesheets. Late arrivals, early departures, overtime and rest-day work are calculated for you — which matters because those records drive both payroll and statutory leave pay.

MPF contributions

Mandatory Provident Fund contributions are computed on the correct relevant income, capped at the statutory minimum and maximum levels, and split between employer and employee shares. The system produces the contribution files your MPF trustee expects.

Employee records and self-service

Contracts, personal details, emergency contacts and documents live in one access-controlled place. Staff can check their own leave balance, apply for leave and download payslips without emailing HR — which is usually where the biggest time saving shows up.

IR56B and IR56E reporting

Year-end employer’s returns (IR56B) and notifications for new joiners (IR56E) are generated from data you already hold, so filing season becomes an export rather than a data-entry project.

Payroll, Without the Month-End Panic

Payroll is usually the first module Hong Kong SMEs ask for. Salaries, MPF, deductions and final payments are calculated from the same attendance and leave records described above, then paid out with payslips issued automatically. Because every figure comes from one source, your MPF and IRD reporting stays consistent with what staff were actually paid — the reconciliation that eats a day every month simply stops happening.

If payroll is your starting point, we have a separate guide to payroll system Hong Kong covering MPF contributions, IR56B/IR56E filing and statutory leave pay.

Where It Runs: On Your Own Premises

Your HR data is the most sensitive information the company holds. This system is not a cloud subscription: we install it on a machine inside your own office — Linux and Docker, with the application, the PostgreSQL database and the Nginx web server running as separate containers — and your staff reach it over your own network.

• Your data never leaves the building. Customer records, salaries, MPF data and financials sit on hardware you control. Nothing is uploaded to a vendor’s cloud, and nothing is sent to a public AI model.
• No software licence. The platform is Odoo 19 Community Edition, which is open source, so there is no per-seat licence to buy on top of the monthly fee.
• Not dependent on your internet line. Day-to-day work runs over your own network, and it keeps working when the broadband does not.
• Open source, so no lock-in. The platform and the custom modules are yours to inspect. No vendor can switch your system off or hold your data to ransom.
• One machine, standard parts. Everything runs in Linux containers (Docker), so the system is portable — it can be backed up, moved, or rebuilt on replacement hardware.

You do not need a server room or an IT department: we set up the machine and maintain it as a managed service.

Affordable Pricing Model

The typical approach involves a one-off setup fee to configure and customise the system for your business and install it on your own premises, followed by a monthly fee banded by the number of modules and the number of users. A bigger team is more people to support, so the fee steps up in bands — the smallest configuration starts at around HK$500 a month. This means:

• No software licence fee — the monthly fee is a service fee, banded by modules and users
• No locked-in contracts
• Easy to add modules as your business grows

For businesses currently using spreadsheets, our team can also assist with data migration and IT support to ensure a smooth transition.

Why Hong Kong SMEs Choose This Approach

• Cost-effective — A fraction of the price of branded HR systems
• Customised to you — Your leave policy, your overtime rules, your approval hierarchy
• Local compliance — Built for Hong Kong’s MPF, tax, and employment regulations
• Scalable — Start with core HR modules and add more as you grow
• Hong Kong-based support — We are local, so responses are fast and relevant

Is It Right for Your Business?

If you have 20–100 staff and are still managing HR with spreadsheets, or paying too much for a system you only use half of, a custom HR system is worth considering. The low development cost model makes it accessible for SMEs, while the flexibility ensures it adapts to your business — not the other way around.

Potoco builds the same way for other business functions — see our custom ERP for Hong Kong SMEs and the rest of our business management systems, or if you need the system supported day to day, look at our IT support outsourcing plans.

Frequently Asked Questions

How much does an HR system cost in Hong Kong?

Expect a one-off setup fee to configure the system around your policies and install it on your own premises, then a monthly fee banded by the number of modules and users — the smallest configuration starts at around HK$500 a month. There is no software licence to buy, so the running cost stays a fraction of what a branded HR suite charges per user per year.

Can staff use an online HR system from their phones?

Yes. Leave applications, payslips and attendance are all browser-based, so staff can use them from a phone or laptop, in the office or remotely. There is nothing to install.

Is a cloud-based HR system safe for payroll data?

Access is role-based and auditable: payroll figures are visible only to the people who should see them, and every change is logged. Hosted storage with backups is generally safer than a spreadsheet sitting on a shared drive.

What is the difference between an HR system and an HRM system?

In practice the terms are used interchangeably. HRM (human resource management) usually implies a slightly broader scope — recruitment, performance and training alongside records, leave and payroll — but the core is the same employee database.

How long does implementation take?

Core HR and payroll for a 20–100 staff company typically goes live within a few weeks, once your leave policy, overtime rules and approval hierarchy are confirmed.
