Web management systems
Registrations, finance, inventory, receivables and reports, accessed from the browser with individual user logins.
Custom software built around the way your business works.
SX Sistemas is a custom software development company. We design systems, applications and automation based on your process.
When your own system makes sense
Not every business needs custom software. These are the most common signs that the time has come.
Operations run on spreadsheets
Parallel controls, different versions of the same file and information that depends on a single person.
Off-the-shelf software doesn't fit
The team bends the process to fit the tool, and month-end closes with workarounds.
Too much repetitive manual work
Copying data from one place to another, building files by hand, checking everything twice.
Data is scattered
Each department has its own source and nobody has a reliable view of the whole when it's time to decide.
What we build
The scope follows the need: from a single automation to a complete management system.
Windows applications
Desktop software with its own installer, running on your company's computers without depending on a browser.
Integrations and automation
Systems talking to each other, file and invoice imports, automatic generation of reports and remittance files.
Interface design
Screens designed for people who use the system every day: few clicks, clear information and shortcuts where they matter.
Websites and pages
Company websites, product pages and support channels with your brand's identity.
System modernization
Database migration, code reorganization and new screens for existing systems that need to evolve.
How we work
Delivered in stages, with the system in real use early on. You follow and approve every step.
Understand
We talk to the people who will use it, map the current process and decide what to solve first.
Design
We lay out the screens and the flow before writing code, so you approve how the system will work.
Build
We develop in parts, delivering versions you can already test with real data.
Support
We deploy, train your team and keep improving as real use shows what to change.

Frequently asked questions
If your question isn't here, just message us on WhatsApp.
Do I need to have everything defined?
No. The first stage exists precisely to organize the need. From our conversation, we turn the problem into a clear, prioritized scope.
How much does custom software cost?
It depends on size and complexity. Once we understand the scenario, we send a proposal with scope, stages and pricing defined before we start.
Can we start with one part and grow later?
Yes, and that's the path we recommend. We start with what brings the most results and the system grows as your operation needs.
Do you keep working with us after delivery?
Yes. We can continue with support, fixes and new features. Support terms are agreed when you hire us.
Tell us what needs to change in your operation.
A quick conversation to understand the scenario. Then we work out the best path together.
