ALL NEW 3S Moving forward

Our expertise in custom software has evolved. So has our ability to innovate.

Since 2011, we have developed software solutions for businesses of different sizes and industries. Today, we combine that experience with our own software products, automation, and artificial intelligence applied to real-world processes, while preserving the flexibility and close collaboration that have always defined our work.

Problems we solve

When your business processes need a better solution.

From specific needs to end-to-end operations, we develop custom software to eliminate repetitive work, connect information, and improve management — complementing or replacing existing solutions as needed.

Spreadsheet-driven processes Key controls depend on Excel files, parallel versions, and manual cross-checks.
Rework and manual tasks Teams copy data, re-enter information, and repeat checks that could be automated.
Scattered information Data is spread across systems, emails, and files — and no one has the full picture.
Hard-to-track operations It takes effort to know the status of requests, deadlines, open items, and owners.
Unreliable metrics Hand-built reports, numbers that don't reconcile, and decisions made without consistent data.
Systems that fall short of operational needs Missing, limited, or outdated solutions that can't keep up with the company's real needs.
Documents and data at volume Contracts, reports, and forms that can be read, classified, and analyzed with the help of AI.

Business solutions

From a specific need to a complete enterprise solution.

We develop new applications, modernize existing systems, and integrate processes and information. From targeted solutions to complete enterprise platforms, we deliver technology tailored to each operation's needs while meeting IT security and governance requirements.

Custom development Complete business systems or specialized applications, developed around your business processes and needs.
Departmental systems Applications for specific areas of mid-sized and large companies, with their own workflows, rules, and controls.
Integrations Connections to ERPs, databases, portals, and the other systems your company already uses.
Process automation Fewer manual tasks, less rework, and more control over steps, deadlines, and owners.
Applied AI Reading, classifying, and analyzing documents and data, with human review when needed.
Support and evolution Maintenance, support, new modules, and hosting on your infrastructure or operated by 3S.

Engagement models

A contracting model for every business need.

The model is defined together, based on scope, infrastructure, and your company's needs. Models can be combined over time.

Terms, investment, and timelines are set out in a specific proposal for each project.

01 Fixed-scope project

Software development with defined scope, investment, and deliverables, deployed on the client's infrastructure or in a contracted environment.

02 Deployment and monthly operation

Development, hosting, support, and ongoing maintenance handled by 3S, under the terms of the contract.

03 Continuous evolution

Monthly development hours or dedicated capacity for ongoing enhancements, improvements, new modules, and integrations, including work on existing systems.

04 Source code acquisition

The option of a contractual transfer of the source code, which can be combined with a subsequent continuous-evolution contract.

Enterprise experience

Experience built on real-world projects.

Since 2011, 3S has developed, deployed, and maintained software systems for businesses of different sizes and industries. Our experience ranges from applications for specific departments within large organizations to complete solutions supporting business operations.
