Mobile and web applications
For customers, teams, sales, support, and field operations, including offline scenarios.
The problem
Your business already works. The bottleneck is in theway the operation runs.
Parallel spreadsheets, scattered messages, re-entering data, and rules only a few people know work fine until volume grows. After that, every new client adds more rework, more risk of error, and more management difficulty.
Critical processes still depend on spreadsheets, emails, or WhatsApp.
The same information gets typed or checked more than once.
Off-the-shelf software doesn't fit the business's rules and exceptions.
Management can't see the whole operation in one place.
Custom software organizes the company's real workflow, connects the systems, and turns business rules into consistent processes.

Why build with NexUnio
Experience to understand the operation before writing a line of code.
An experienced software house doesn't just deliver screens. It understands the business rules, reduces project risk, and builds a foundation that keeps evolving after launch.
16 years developing software for real operations.
Senior team involved from the very first conversation.
A custom-built project, not a template with the logo swapped.
Code, repository, and infrastructure in the client's name.
Integration with ERPs, payments, WhatsApp, and existing systems.
Progressive delivery, monitoring, and continuous evolution.
AI is used only when it adds measurable value to the workflow.
Engineering
Architecture built tooperate, integrate, and evolve.
Data starts in the field, flows through the layer we build, and reaches the systems your company already uses, with no re-typing along the way.

How it works
Four steps, from diagnosis to evolution.
Diagnosis
In 30 minutes, we understand the operation, the goal, and the main constraints.
Scope and path
We define priorities, integrations, and an initial estimate of timeline and investment.
Build in stages
The product evolves in short cycles, with client validation and visibility into progress.
Launch and evolution
We go live, monitor usage, and prioritize the next deliverables.
Depending on scope, the first usable version is typically delivered within 3 to 6 weeks after the project is defined.
Investment
Custom-built projectsstarting at R$50,000.
We don't work with a fixed price table, because every operation calls for different rules, integrations, and security levels. In the initial conversation, you'll get a ballpark estimate. The final range is set once the scope is designed.
Makes the most sense for companies with a proven operation and a concrete bottleneck.
The project needs an internal owner and access to the people who know the process.
NexUnio is the right fit when software is treated as an operational asset, not just a screen to be delivered.
Who it's for
Built for those who want to scale.
We work with companies that see software as a competitive advantage, not a cost. If you have a process that deserves to become a product, or a product that needs real AI, let's talk.

Questions before you start
What everyone asks.
What does NexUnio build?
Mobile and web apps, internal systems, portals, platforms, marketplaces, and custom digital products. The architecture can combine integrations, payments, data, automation, and AI.
Who owns the code?
On custom projects, the code, repository, and infrastructure stay in the client's name. NexUnio can keep working on future development, but the client is never locked into a vendor.
How long does it take?
It depends on the scope. The first usable version usually arrives 3 to 6 weeks after the project is scoped. Larger projects roll out in phases.
How much does it cost?
Projects start at R$50,000. The initial conversation gives you a ballpark estimate, and the final range is set once the scope is defined.
Do you integrate with what we already use?
Yes. ERP, CRM, payments, WhatsApp, databases, and existing APIs can all be part of the architecture.
Do you use AI on every project?
No. AI comes in when it cuts costs, speeds up revenue, or improves a meaningful step. In many cases, a simple integration or automation works better.
How do you handle security and data protection (LGPD)?
Access profiles, encryption, backups, audit trails, and data handling are defined according to how critical the operation is.
What happens after launch?
NexUnio can keep monitoring and evolving the product in ongoing cycles. Since the code belongs to the client, continuity never depends on lock-in.
Do you work with companies outside São Paulo?
Yes. The whole process can run remotely, with meetings, validations, and ongoing follow-up.
