How to Choose a Time and Attendance System:
A Buyer's Guide
Time and Attendance Systems Buyer's Guide

Choosing the right time and attendance system can help businesses accurately manage employee working hours, simplify payroll preparation and improve absence management. 

The best system for your business will depend on how your employees work, the complexity of your shift patterns, the clocking methods you need and the software you already use. You should also consider reporting, data protection, scalability and the total cost of ownership. 

This buyer's guide explains how to compare time and attendance systems, which features to look for, what to ask suppliers and how to assess the potential return on investment. 

What is a Time and Attendance system?

A time and attendance system records when employees start and finish work, which helps businesses monitor working hours, lateness, breaks, overtime and absence. 

A typical system combines clocking hardware, such as smartcard or biometric terminals, with time and attendance software that stores and processes clocking records. Managers can use the software to review attendance, manage exceptions, approve amendments and generate reports for workforce planning or payroll. 

Depending on the system, additional features may include remote clocking software, holiday booking, and integration with payroll, HR and Access Control systems.  

Identify your workforce management challenges

Before comparing time and attendance systems, identify the problems you need the new system to solve. Review your existing processes and speak to managers, HR staff, payroll administrators and employees to understand where the problems are.  

Common workforce management challenges include: 

  • Manual administration: Time spent collecting timesheets, checking clocking records and processing amendments. 
  • Payroll errors: Incorrect working hours, missed clockings or overtime calculations leading to pay discrepancies. 
  • Absence management: Difficulty tracking annual leave, sickness absence and remaining holiday entitlement. 
  • Limited workforce visibility: Unable to see who is on site, working remotely, absent or working across different locations. 
  • Inconsistent processes: Different sites or departments using their own methods to record working hours and approve leave. 
  • Limited reporting: Problems identifying attendance patterns, monitoring overtime and investigating discrepancies. 

Once you have identified the main issues, establish what you want to achieve. This might include reducing the time managers spend reviewing working hours, improving shift assignments or improving visibility across multiple sites.  

Match the system to your workforce and worksite

Where your employees work and the way they work will influence the type of system you need. 

For example, a manufacturing business operating several shifts may prefer a system with fixed smartcard clocking terminals and comprehensive reporting, whereas an office-based business with employees that work from home may prefer an online time and attendance platform where they can clock in and out from anywhere. 

You should also consider how employees will clock in and out and how the software will be used by managers and administrators. Can managers approve timesheets and absences for their own teams? Can HR access organisation-wide records? Can permissions be restricted according to job role?  

Make sure to check your chosen time and attendance system can meet your requirements before committing to it.

Compare Time and Attendance clocking methods

The clocking terminal and credentials chosen for your system will determine efficiency, security and overall cost of a time and attendance system. 

The most suitable method depends on your workforce, site conditions, the level of verification needed and budget. Some businesses may benefit from combining fixed clocking terminals with mobile or web-based clocking for different employee groups. 

Method

Potential Advantages

Considerations

Smartcard or fob

Quick, familiar and easy to issue

Can be lost, shared or stolen; replacements may incur additional costs

Fingerprint biometrics

No physical credential required for verification

Performance can be affected by working conditions, hand condition and gloves; biometric data protection requirements apply

Facial authentication

Touch-free identification and convenient clocking at busy entry points 

Check compatibility with PPE, environmental conditions, liveness detection and data protection requirements

Mobile and Web

Supports remote, hybrid and mobile workers

Consider how clocking location is verified

Cards and Fobs 

Smartcards and key fobs are the most common way to record employee attendance. These are distributed individually and employees present their assigned credential to a compatible time and attendance terminal, which records the clocking against their profile in the system. 

These can be a practical choice for businesses where employees regularly enter and leave near designated clocking points. Smartcards can also double up as ID badges, as a straightforward way to identify employees. However, cards and fobs, like anything physical, can be lost, shared or stolen. A clocking record made using a smartcard does not necessarily prove that the person carrying it is the assigned employee. 

The cost of purchasing and replacing these credentials should also be a factor to consider, as well as how easily lost cards can be deactivated and leavers' cards can be reassigned.

Biometric Clocking: Fingerprint and Facial Authentication 

Biometric clocking terminals use an individual's characteristics to verify an employee's identity and reduce reliance on physical credentials. 

Fingerprint readers may be suitable for many workplace environments with on-site employees, but performance and reliability can be affected by the condition of a person's hands, the working environment and the need to wear gloves. 

Facial authentication provides a touch-free alternative, ideal for workplaces like food manufacturers, where hygiene standards are important, or where a quick clock in is required. Although most facial authentication devices work with partial face coverings, they may not be suitable for businesses where employees need to wear full PPE. Modern facial authentication technology should have safeguards against spoofing and fraud, with live detection features ensuring that a real person is using the scanner, not a photograph or video. 

Something else to note is that biometric data is subject to additional UK GDPR requirements and requires careful and secure handling, including under what circumstances it can be collected, how long it can be kept and what can be done with it. When evaluating suppliers, ask how biometric data is captured, stored, protected, retained and deleted. You should also review the supplier's security controls and relevant certifications, such as ISO 27001, where applicable. Certifications can support your assessment of security practices, but they do not replace your own data protection responsibilities. 

Mobile and Web-based Clocking 

Web-based time and attendance platforms and mobile apps allow employees to record working hours without having to use a physical clocking terminal located on-site. They are particularly useful for employees that work remotely or travel often. The best time and attendance systems give employees the ability to view their attendance records, request annual leave and more from wherever they are.  

For predominantly site-based workforces, fixed clocking terminals may be more appropriate, while other organisations may benefit from a combination of both.  

If you are considering a web-based time and attendance system or mobile app, check which self-service and absence management features are available to employees and managers. 

Questions to ask include: 

  • Absence visibility: Can managers view absence calendars by department and across the organisation? Can they access relevant attendance statistics, including Bradford Factor reporting if required? 
  • Approval workflows: Can managers receive notifications and approve clocking amendments, annual leave requests and cancellations? Are return-to-work forms supported? 
  • Employee self-service: Can employees view their annual leave entitlement, leave taken, booked leave, remaining balance and pending requests? 
  • Shift visibility: Can employees view their scheduled rotas and working patterns? 
  • Access permissions: Can managers see the information relevant to their teams while HR retains access to organisation-wide records? 

The available features will vary between systems, so ask suppliers to demonstrate the workflows your organisation uses in practice. 

Types of Time and Attendance Credentials

Payroll, HR and Access Control Integrations

The data collected by a time and attendance system can be even more valuable when used alongside other systems, such as payroll and HR packages and access control solutions.

Payroll Integration 

Choosing a time and attendance system that can integrate with third-party payroll packages means that approved data can be automatically transferred into your payroll software, without the need to manually enter it. This can significantly reduce the number of human-made errors and therefore cut the time spent doing payroll tasks. 

Check that the system supports your specific payroll software and establish exactly what information is transferred. This may include working hours, overtime, absence information and pay codes. You will also need to check whether the connection is direct, uses scheduled file exports or if it requires a custom development, as this may affect the overall cost of the system.

HR System Integration

Connecting time and attendance systems with HR software can help keep employee information consistent across systems. This integration may allow information such as employee details, new starters and leavers and qualifications to be automatically synchronised, and may also help when it comes to scheduling rotas. For example, a business may need to check that a qualified first aider is present on every shift and identify when employees' qualifications are due for renewal. If these records are managed in a separate HR system, ask whether the relevant information can be accessed or synchronised. 

Access Control Integration 

Integrating time and attendance with access control can enhance overall site visibility, security and efficiency. Sharing records between these systems can speed up access permission processes, ensure people can only access the premises during their scheduled work times, and help investigators establish who accessed particular areas and when. 

Some suppliers offer time and attendance alongside access control, visitor management, CCTV and HR software. If you need several of these capabilities, compare the benefits of an integrated solution with those of separate specialist systems, including the cost, reporting and ongoing support implications.

Essential Time and Attendance software features 

Support for shift patterns, overtime and exceptions 

Clocking records are only part of the picture. Depending on the nature of your business, you may need to manage complex working patterns, multiple pay bands, remote workers, and exceptions that affect how employee hours are calculated.  

Check whether the system can accommodate requirements such as: 

  • Rotating shift patterns and shift swaps 
  • Flexible working hours and flexitime balance reporting 
  • Overtime rules and pay bands 
  • Time off in lieu (TOIL) 
  • Different working rules for departments, employee groups or sites 
  • Remote or hybrid staff 

How easily can these rules be configured and amended? A system that cannot accommodate your existing processes may introduce extra work for managers.  

Time and attendance system providers should offer a free demonstration, where you can ask them to show how their system would handle your actual working patterns.  

Reporting and management information 

Accurate attendance records are most useful when managers can turn them into clear reports for payroll, workforce planning and attendance management.  

A time and attendance system should provide the information your business needs to manage working hours, investigate discrepancies and prepare payroll. Depending on your requirements, useful reports may include: 

  • Employee working hours and attendance records. 
  • Late arrivals, early departures and missed clockings. 
  • Overtime hours and associated costs. 
  • Annual leave, sickness absence and other authorised and non-authorised absences. 
  • Attendance summaries by employee, department or site. 
  • Exceptions, amendments and approval histories.  

You should also check if your time and attendance system will give you the opportunity to create your own bespoke reports, whether they can be filtered by date, employee, department or location, and whether this data can be exported in formats your business can use. 

Absence and holiday management 

A time and attendance system should make it easier to manage annual leave, sickness absence and other time off, while giving managers a clear overview of availability across their team.  

Depending on your business requirements, useful features may include: 

  • Holiday entitlement and balances: Automatically calculate annual leave entitlement, track leave taken, booked, and remaining. 
  • Absence requests and approvals: Allow employees to submit holiday requests and managers to approve, decline or amend them. 
  • Absence calendars: View planned absences by employee, department or site to help with workforce planning and shift cover or view historic unplanned absences to track patterns. 
  • Sickness absence tracking: Record sickness absence, monitor attendance patterns and support return to work processes. Some systems also include Bradford Factor reporting, helping managers understand where further investigation may be appropriate.
  • Notifications and reporting: Alert managers to pending requests and outstanding return to work forms and allow the creation of bespoke reports.  

When comparing systems, check whether absence rules can be configured to reflect your policies, including different holiday entitlements, working patterns and approval processes. You should also establish whether the system can provide the reports and records needed by HR, managers and payroll. 

How much does a Time and Attendance system cost?

The total cost of a time and attendance system will depend on the size of your workforce, the hardware required, software licences, integrations and extras like training and maintenance packages. When comparing quotes, consider both the initial investment and the ongoing costs. 

These costs may include: 

  • Clocking terminals, readers, cards and fobs 
  • Software licences and per user charges 
  • Installation, configuration and implementation 
  • Integrations 
  • Administrator and manager training 
  • Ongoing support, maintenance and upgrades 
  • Additional modules, sites or hardware that may be required at a later date 

A lower initial price may not represent the best value if essential features, integrations or support are not already included in the quote. 

Financing options

The upfront cost of a new system can be a consideration, particularly if you are also upgrading related systems or installing new hardware across multiple sites. 

It's worth asking suppliers whether they offer phased implementation, modular purchasing or financing options. Starting with the most important requirements and later expanding the system may help spread investment over time, provided the initial system meets your operational needs. 

Tensor offers modular time and attendance solutions, allowing businesses to configure a system around their requirements. Financing options are also available, subject to eligibility.  

Return on Investment 

The cost of a system should be considered alongside the potential savings and operational improvements it could deliver. 

Possible benefits of a modern time and attendance system include reducing the time spent processing timesheets, correcting payroll errors, managing absences and investigating attendance discrepancies. 

Tensor's time and attendance ROI calculator can help you explore the potential return on investment for a time and attendance system. Use realistic assumptions and compare them with your actual costs wherever possible.

Legal compliance and data protection

A time and attendance system needs to support your organisation's working time regulation agreements, absence management and record-keeping requirements.  

It needs to help you maintain accurate records, apply your working rules consistently and retrieve the information needed for management and payroll processes. However, software alone cannot guarantee legal compliance. 

Working Time Regulations

The Working Time Regulations 1998 covers legal requirements relating to working hours, rest breaks, daily and weekly rest periods and annual leave. 

When evaluating a time and attendance system, consider whether it can help you monitor working hours, apply your organisation's rules consistently and identify potential infringements, such as excessive hours or missed breaks. 

Check which records the system maintains and whether its reports support your specific monitoring and record-keeping requirements. Employers remain responsible for understanding and meeting their legal obligations. 

Employment Rights Act and Statutory Sick Pay

Changes introduced on 6th April 2026 under the Employment Rights Act 2025 include a requirement to retain adequate records relating to specified annual leave entitlements and requirements for six years. 

Changes to Statutory Sick Pay (SSP) also removed the lower earnings limit and waiting period, meaning eligible employees can receive SSP from the first full day of sickness absence.  

When evaluating a time and attendance system, check whether it can: 

  • Record annual leave entitlement, leave taken and relevant holiday pay information. 
  • Retain and retrieve records for the required period. 
  • Track sickness absence and support your absence management processes. 
  • Apply your business' working time, overtime and shift rules. 
  • Provide accurate information for payroll and management reporting. 

You should also establish whether the system can accommodate your existing policies and how easily it can be updated when requirements change. 

Data security and data protection

A time and attendance system is designed to hold employee information and as such, that information needs to be handled appropriately. The following should be considered: 

  • Access permissions: Can access to employee records be restricted according to job role? 
  • Audit trails: Can you see who has changed a record, when the change was made and what was changed? 
  • Data security: What safeguards are in place to protect information against unauthorised access, loss or disclosure? 
  • Data retention: Can retention periods be configured appropriately and records securely deleted when no longer required? 
  • Biometric information: If biometric clocking is used, how is the information processed, protected and retained? 

Conclusion: Choosing the right Time and Attendance system for your business. 

Choosing the right time and attendance system means finding a solution that fits your workplace, simplifies day to day administration and supports your business as it grows. By assessing your clocking requirements, software features, integrations, reporting needs and budget, you can compare systems more effectively.  

Before making a decision, it is important to ask suppliers to demonstrate how their system handles your working patterns and processes. Most suppliers will offer a free demo which can be booked online or directly with their sales team. This is an important opportunity to check that the system meets your requirements before committing. Also, check the support available and the total cost of ownership including any maintenance and training costs.  

Future-proof your purchase by ensuring the system is modular and can grow and adapt as your needs do. This may mean not choosing the cheapest system but instead investing in a solution that offers the right functionality, flexibility and support to deliver long term value and avoid costly upgrades or replacement further down the line.
