When a company has 5-10 stores, shift schedules can still be created in Excel. One administrator keeps track of vacations, sick leaves, and norms in their head — and manages. But as the network grows, this model breaks first.
With 100+ stores and thousands of employees, manual planning turns into a daily risk: an understaffed store on a weekend, overtime that has to be covered with additional payments, or a schedule that falls apart due to a single personnel change. This is where the WFM system comes into play — a tool that takes this burden off people and hands the calculations over to algorithms.
What is a WFM system and why does it matter to business
WFM (Workforce Management) is a system for distributing and managing employees' working hours. It automates shift planning, tracking worked hours, monitoring absences, and calculating norms according to labor laws.
Main tasks of the WFM system
Planning shift schedules considering legal norms and business needs
Tracking working time: hours worked, vacations, sick leaves
Managing employee access based on role and position
Analytical reporting on personnel workload
Automatic detection of violations - overtime, insufficient rest between shifts
Who, besides retail, will benefit from WFM?
Although retail is the most active user of WFM due to its large network structure, the architecture we are building based on Odoo is perfectly suited for any business with a distributed structure:
Logistics and warehouses - where it is critically important to plan variable loads, taking into account the arrival of transport and the volume of shipments
Manufacturing - where there are strict production standards, shift schedules, and the need for strict compliance with labor legislation
Service sector (HoReCa, service centers) - where schedules must adapt to peak customer influx hours to maintain service quality
Financial and banking networks - where it is important to ensure staff presence according to the branch's working hours
The versatility of Odoo allows for adapting logic to any industry while maintaining centralized control and transparency of all HR processes.
Building WFM based on Odoo ERP: scaling without architectural limitations
Odoo is a modular open-source ERP system, and this makes it a strong choice for WFM projects. Unlike rigid off-the-shelf solutions, Odoo allows you to build planning logic tailored to a specific business rather than forcing the business to fit a system template.
Planning logic, not a system template. Each network has its own rules: standards by department format, priorities in schedule conflicts, specific scenarios for HR events. In Odoo, these rules can be embedded directly into the system's logic rather than kept in the heads of managers or in informal instructions.
Access rights that correspond to the real hierarchy. Odoo provides flexible access rights configuration: the object manager sees their employees, the regional manager sees the summary for the region, and HR sees the complete picture of the network. This is critical at a scale of thousands of employees, where improperly distributed access creates both operational and security risks.
Architecture designed for growth. A well-designed WFM on Odoo is ready to open new locations without additional costs for reworking the architecture — the system is built for network growth from the very beginning.
All rules and payment coefficients are embedded directly into the system's HR logic. Odoo automatically distinguishes regular hours, night work, or official holidays, marks them in the timesheet, and generates ready data for further payroll processing without manual calculations from accounting or HR.
Thanks to an optimized server architecture (load balancing, database clustering, and the use of reliable cloud resources), Odoo can withstand peak loads. The system ensures fast request processing and instant data saving even under conditions of thousands of parallel sessions from users in different regions.
Yes, the flexible Odoo API allows for easy integration with any external devices and security systems. This enables automatic comparison of the planned schedule with the actual time of entry or fingerprint scanning, recording delays, absences, or early departures for accurate timekeeping.
Case: WFM automation for the "Avrora" network - 1800+ stores, 10,000+ retail employees (out of 16,000+ total employees).
The company "Aurora" is one of the largest retail chains in Ukraine. Before implementation, it managed schedules and personnel accounting through its own custom system. It successfully supported operations during the establishment phase, but the rapid growth of the network required a transition to a more flexible architecture. To support the scale of the company, a solution with higher potential for quick adaptation of processes was needed.
We deployed a WFM system based on Odoo Community, which covered:
Work schedule management — automated shift planning for 10,000+ employees across 1,800+ stores
Access management system — flexible access rights depending on role and position
Time tracking — recording worked hours, absences, and vacations for accurate payroll calculation
Staff unit accounting — organizational structure of stores and management hierarchy
Analytical reports — comprehensive reporting on staff workload and schedule effectiveness
The main challenge of the project was not to "fix" the process, but to accurately translate the already validated business logic of the company into the language of Odoo — without losing any nuances from the thousands of work rules accumulated over the years.
The result: the company received a transparent centralized system, full control over staff and work schedules, as well as an architecture ready for opening new stores without additional costs for rework.
The WFM system on Odoo is not an off-the-shelf solution, but an architecture built for a specific business: its norms, roles, and personnel processes. The case shows that even a network of this scale can transition from a custom system to Odoo without losing flexibility — and gain transparency, savings on IT infrastructure, and readiness for scaling.
