GTA BTP 2025 Software: A Complete Guide to Choosing the Best Solution

Digitalization remains a major challenge for the construction sector, which remains one of the least digitized despite its considerable economic weight. However, businesses that adopt digital technologies increase productivity by 14 to 15% and reduce costs by 4 to 6%. These numbers represent average estimates and may vary depending on the size of the company, the type of site and the level of digitalization already in place.

In this context, Time and Activity Management (GTA) software represents a potential strategic lever for construction and public works companies. These tools make it possible to manage mobile teams, optimize multi-site schedules, ensure regulatory compliance and significantly reduce administrative burden.

This comprehensive guide shows you the best GTA solutions for construction in 2025, the essential choice criteria and how to successfully integrate them into your IT ecosystem.

What is GTA software in construction?

The construction sector has unique specificities that require adapted tools. Before exploring the available solutions, it is essential to understand exactly what GTA software is and why it is a strategic lever for your business.

Definition and sectoral specificities of the construction industry

Contrary to popular belief, GTA software is not limited to a simple digital time clock. In the specific context of construction, this tool must respond to much more complex challenges.

GTA (Time and Activity Management) software is a digital solution that records, tracks and analyzes the working hours of employees. In the construction industry, this solution must meet specific constraints: teams scattered on several sites, variable hours, changing weather conditions, and strict sectoral regulations.

Construction professionals devote up to 8 hours per week to the administrative management of construction sites, financial monitoring and quotations. A powerful GTA software makes it possible to drastically reduce this unproductive time.

Essential features

A powerful GTA software for construction is distinguished by its ability to manage the entire work cycle on site. Here are the features that really make a difference in the field.

Mobile and geolocated clocking : the workers badge directly from the construction site via their smartphone, even without an internet connection. Geolocation guarantees effective presence on site.

Multi-site management : automatic assignment of employees to the various sites with time tracking by project and breakdown of labor costs.

Overtime calculation : automatic application of increases according to collective agreements in the construction and public works sector (125%, 150%, night and public holiday increases).

Weather Management : simplified declaration of weather stops and calculation of compensation in accordance with sectoral regulations.

Analytical reporting : real-time dashboards on activity, costs per site, attendance rates and productivity.

To note : the functionalities and benefits described may vary depending on the software chosen and the configuration of your business. It is recommended that you check each feature during the demo.

Concrete benefits

Beyond commercial promises, what are the real and measurable gains for a construction company? Feedback from field experience reveals several tangible benefits.

Adopting GTA software generates several measurable gains:

• Reduction of errors : elimination of manual entry errors and disputes over hours worked
• Saves administrative time : savings of 10 hours per week for managers
• Financial visibility : real-time monitoring of labor costs per site
• Guaranteed compliance : automatic application of legal and conventional rules
• Improvement of the social climate : transparency on hours worked and payroll elements

How to choose your GTA software for construction in 2025?

Faced with the multiplicity of offers on the market, choosing GTA software may seem complex. This section guides you through the decisive criteria to identify the solution best suited to your structure.

Priority selection criteria

Not all GTA software is the same, especially in a sector as demanding as construction. Four fundamental criteria should guide your comparative analysis.

Sectoral adaptation : check that the software integrates the collective agreements of the construction industry (workers, ETAM, managers), the management of specific paid leave, and the rules of hardship.

Field robustness : the mobile application must work in offline mode for areas with low network coverage, with automatic synchronization when the connection returns.

Ease of use : choose an intuitive interface that allows scoring in less than 10 seconds, even for users who are unfamiliar with digital technology.

Scalability : Ensure that the solution can support your growth and manage multiple legal entities if necessary.

Integration capabilities

An isolated GTA software loses most of its value. The real challenge lies in its ability to communicate effectively with your existing IT ecosystem.

GTA software never works in isolation. It should integrate with:

• Your payroll software (Silae, ADP, Cegid, Sage) to automatically transmit payroll variables
• Your ERP (SAP, Sage, EBP, Cegid) to synchronize the repositories and go back the imputed times
• Your construction site management tools for monitoring production and profitability
• Your HR systems for a complete vision of employees

To facilitate these integrations, choose software that has open APIs or native connectors to your existing tools. Some solutions like Alobees offer an integrated approach by directly combining site monitoring and time management, thus limiting the number of tools to be connected.

Budget and return on investment

The budget issue goes beyond the simple subscription cost. Let's analyze all the expenditure items and the expected gains to assess the real profitability of your investment.

The price of GTA software in SaaS mode generally comes in the form of a monthly or annual subscription whose price varies according to the number of users. For a standard solution, count between €5 and €15 per user per month, with premium packages of up to €25.

The return on investment is generally achieved in 6 to 12 months thanks to the reduction of administrative time, the reduction of payroll errors and the optimization of the allocation of resources.

Note: the ROI (savings on administrative time and reduction of errors) will depend on your organization, the number of projects and the quality of adoption by your teams.

Alobees: the construction site monitoring software that integrates time management

GTA software alone is not enough: it must be integrated into a global vision of site management. This is precisely what Alobees offers, a complete solution designed for VSEs/SMEs in the construction and public works sector.

What is Alobees?

In the construction sector, the multiplication of tools often creates more complexity than solutions. Alobees provides an integrated response to the daily challenges of building companies.

Alobees is a site monitoring software dedicated to construction professionals. It allows managers, administrative staff, HR, construction managers, site managers and construction company companions to plan work and to have a global and real-time vision of the construction sites in progress.

Created by construction professionals, Alobees is distinguished by its all-in-one approach: beyond simple time management, it centralizes all information related to construction sites (schedules, documents, photos, tasks, hours) in a single interface accessible from a computer, tablet or smartphone.

Alobees centralizes all the essential information of your construction sites in one place: photos, videos, documents, schedules, tasks, hours and more.

Alobees offers three different packs: the first is 40€ HT/company + 10€ HT/user/month, the second at 80€ HT/company + 10€ HT/user/month. A free trial period of 14 days without a bank card is offered, with free unlimited support.

Time management integrated into site monitoring

The advantage of Alobees lies in its ability to combine site monitoring and time management in a single solution. Here's how this integration solves real everyday problems.

Digitized timesheets

On the administrative side, the software Simplifies tracking down the hours from the field and facilitates their processing for payroll, taking into account the specificities of construction (overtime, bad weather, baskets, small and/or large trips, etc.).

Workmen declare their hours directly from the mobile application, on each construction site. No more lost sheets of paper or re-entry errors. Hours are automatically associated with the right work site for accurate analytical monitoring of labor costs.

Load planning and assignment

The load schedule by Alobees allows you to visualize at a glance the availability of your teams over the coming weeks. You understand your needs and anticipate the occupancy rate of your workforce. The assignment of workers to construction sites is done in a few clicks, and each employee instantly receives his schedule via the mobile application.

Field-office communication

With Alobees, access your information from any device — whether it's a mobile, tablet, or computer, whether you're on the go, at work, or at home.

The news feed by site allows field teams to communicate in real time with the office: report an unexpected event, request information, share a photo of progress. This fluidity considerably improves responsiveness and reduces phone calls.

Centralized document management

All of your documents are collected and searchable in a single location, whether they are plans, contracts or minutes. Storage is unlimited and accepts all formats (PDF, JPEG, Excel). The documents are accessible at any time, even from the construction site.

Integrations with payroll and GTA software

Alobees does not work in a vacuum. The software integrates with your existing tools to create a coherent ecosystem.

Native connectors

Alobees is compatible with other software: quotation and invoice software (Sage, EBP, Codial...) as well as payroll/SIRH software (Lucca, Eurécia, Silae).

This compatibility makes it possible to automatically transmit the hours validated in Alobees to your payroll software, thus avoiding any manual re-entry. Data is synchronized in the format expected by each tool, guaranteeing reliability and time savings.

See the integrations and ERP

Concrete use cases

A plastering company uses Alobees to manage its 15 simultaneous construction sites. Every Monday, the operations manager assigns his 30 companions to the various sites via the Alobees schedule. The companions consult their schedule on their smartphone and show their hours every day. At the end of the week, the manager validates the hours in a few clicks. The data is automatically transmitted to Silae Payee via the native connector. The accountant only has to start the payroll, as overtime and surcharges have already been calculated. At the same time, the company manager consults his Alobees dashboards to monitor the real costs per site and identify possible slip-ups.

Benefits of this integrated approach

It is estimated that users of the software or its mobile version save an average of 20% of time in their daily tasks and obtain better profitability in their projects.

FAQ: Essential questions before choosing your GTA BTP software

Before making your final decision, some questions always come up. We answer them in a clear and factual manner to inform your choice.

Which GTA software to choose in the construction industry in 2025?

The choice depends on your size and specific needs. Skello suitable for businesses looking for simplicity and an intuitive interface. Eurécia is essential for those requiring a complete HR suite. Silae is ideal if you are already using their payroll. Lucca seduced by its modern design. Empowill appeals for the global approach integrating skills management and training. Traxxeo reassures by its robustness. Factorial suitable for SMEs for its excellent quality-price ratio.

The main thing is to check the adaptation to collective agreements in the construction industry, field mobility, and integration capabilities. For SMEs looking for an all-in-one solution combining GTA and site monitoring, Alobees is also an interesting option.

How does the GTA software integrate with existing tools (ERP, payroll, construction site management)?

Several levels of integration exist:

• API : flexible data exchange but requires development and maintenance.
• Native connectors : simple pre-packaged integrations but limited to official partners.
• Import/export files : a basic method generating manual tasks and risks of errors.
• Integrated alternative : some software such as Alobees offer an all-in-one approach combining site monitoring and time management, thus reducing the need for multiple integrations.

Examples of flows: SIRH → GTA (employee creation), GTA → Payroll (payroll variables), Construction site management software → GTA (schedules), GTA → ERP (time allocated per case).

Does it make it possible to effectively manage mobile and multi-site teams in real time?

An effective GTA software for construction must offer:

• Powerful mobile application : clocking in less than 10 seconds, interface readable in sunlight, suitable for casual users.
• Indispensable offline mode : clocking possible without connection, local storage, automatic synchronization when the network returns. Verify this feature concretely during the demos.
• Smart geolocation : geolocated clock guaranteeing presence on the planned site, with a configurable tolerance perimeter. Respect for privacy (geolocation only when clocking).
• Multi-site assignment : a companion can work on several sites during the day. The software must make it possible to clock in and out of each site, with automatic allocation of time to the right site.
• Real-time notifications : immediate alerts to site managers in case of absence, delay or anomaly to react and reassign quickly.
• Real-time dashboard : instant visualization of who is present on which construction site, who is absent, who is on the move.

‍

Does it comply with legal and conventional rules specific to construction and public works?

Compliance is critical. GTA software must include:

• BTP collective agreements : several agreements depending on activity (construction workers, public works, ETAM, managers). The software must know and automatically apply the corresponding rules.
• Overtime : special rules in construction. First 8 hours after 35 p.m. at 125%, next at 150%. Automatic calculation and transmission to the required payroll.
• Paid leave : specific system with dedicated cash desks (Bad Weather BTP). Calculation in working days with specific acquisition rules.
• Bad weather : a unique compensation regime for construction and public works. Simplified declaration of weather stops, calculation of compensation and generation of declarations.
• Travel time and short trips : certain travel times considered to be actual working time. Different rules between small and large trips.
• Lunch baskets : benefits subject to precise rules according to agreements. Automatic calculation of the number of baskets due.
• Painfulness : mandatory declaration of exposure to certain factors via C2P. The GTA should facilitate the follow-up and generation of declarations.
• Rest time : respect for 11 consecutive hours between two days and weekly rest. The software should monitor and alert.
• Maximum duration : 10 hours a day, 48 hours a week. Real-time control of these limits.
• DSN : data sent monthly to social organizations. The GTA should generate the data in the expected format.
• Regulatory updates : choose SaaS solutions with automatic continuous updates.

During demos, ask for concrete examples with your specific convention and test complex cases.

What is the average price of GTA software for construction?

The pricing model for SaaS software is in the form of an annual or monthly subscription generally including maintenance costs and updates, with a package whose price varies according to the number of users.

• Price range : between €5 and €15 per user per month for standard solutions, up to €25 for premium solutions with advanced functionalities.
• Additional costs : training (€1000 to €5000 depending on size), initial configuration (data recovery, business rules configuration), possible physical terminals (€300 to €800 per clocking device).
• Expected ROI : return on investment in 6 to 12 months via reduction in administrative time (equivalent to 0.5 to 1 FTE for 50 people), reduction in payroll errors (2 to 5% savings on payroll), optimization of resource allocation (productivity gain 5 to 10%).
• Criteria influencing the price : number of users, activated modules, level of customization, required integrations.
