When Off-the-Shelf Software Isn't Enough
When off-the-shelf software can't keep up with your operation
Not every process fits into an off-the-shelf ERP. When a company starts adapting its operation to the software — instead of the other way around — the cost shows up as parallel spreadsheets, rework, improvised integrations, and missing information.
How we can help
From a brand-new system to evolving the one you already have.
3S works at different stages of a system's life — and can take on a single stage or the full cycle.
- Develop a complete business system or a specialized application tailored to your company's processes and needs.
- Modernize an existing system, keeping what works and removing its limitations.
- Automate operational and administrative processes, reducing spreadsheets, repetitive work, and manual tasks.
- Integrate internal systems, so information flows without re-keying.
- Deploy AI-powered solutions to read, classify, and analyze documents and data.
- Host and operate applications, when your company prefers not to manage the infrastructure.
- Maintain and evolve the software continuously, with improvements, new modules, and support.
What We Build
Software Built Around Your Operation
One engineering team covers most of what a corporate system requires: management, portals, systems integration, data, and automation. Applied AI is one of the capabilities of this work — built into the process, with review and traceability — not a separate product.
Working with corporate IT
The solution fits into your technology ecosystem — including your ERP.
We develop complete business systems or specialized applications, integrating them with existing technologies when needed. Each project takes the client's IT security, integration, and governance requirements into account, with deployment on the client's infrastructure or in an environment hosted and operated by 3S.
Real Projects, Real Operations
A few examples of systems 3S has built for specific business processes.
Let's Talk
Tell us what your business needs to develop, modernize, or automate. Our team is ready to learn about your project and discuss the possibilities.
Let's discuss your projectHow We Work
Clarity before we build. Delivery in stages. Continuous evolution.
We understand processes, data, rules, people, exceptions, and existing systems before choosing any technology.
We design flows, integrations, permissions, data, and architecture around the real operation.
We build usable versions and evolve them through continuous validation.
After deployment, the system keeps up with changes in the business — some projects have evolved with us for many years.
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.
Software development with defined scope, investment, and deliverables, deployed on the client's infrastructure or in a contracted environment.
Development, hosting, support, and ongoing maintenance handled by 3S, under the terms of the contract.
Monthly development hours or dedicated capacity for ongoing enhancements, improvements, new modules, and integrations, including work on existing systems.
The option of a contractual transfer of the source code, which can be combined with a subsequent continuous-evolution contract.
Real-World Experience
Software that keeps evolving years after deployment.
Since 2013, 3S has developed the modules of our integrated management system, always with high quality, on schedule, and with excellent service. It integrates our processes, strengthens controls, and supports fast, effective decision-making.
We've been 3S clients since 2011, when we implemented our ERP. Our system was entirely designed, built, and customized for our processes. Many tools have been added and refined since then, always with great quality and precision.
The best system we've ever implemented at our company. 3S is a serious company with excellent professionals and outstanding support. The system they built has been a major driver of our growth.
