Custom tools

Custom software

When spreadsheets and chat threads aren’t enough, we build the right tool for your operation.

Not every business needs a giant ERP. Sometimes you need a panel to manage products, an organized form, or an integration with Mercado Pago or WhatsApp.

We design custom software focused on daily use: few screens, plain language, and flows your team understands without endless training.

It might be an internal catalog, a backoffice for your site, a client follow-up system, or a piece that connects what you already have. We start from the problem, not the tech.

If the project is large, we split it into stages: first what unlocks value, then what scales.

FAQ

When is custom software better than a regular website?

When you need data entry, permissions, business rules, or flows a static page can’t handle. If you only need presentation and contact, a website is usually enough.

Do you work with systems I already have?

When it’s reasonable, yes — we integrate or import data. If the current tool can’t support it, we propose a simpler alternative.

Do you give a fixed price upfront?

We define staged scope with a clear budget. We avoid quoting “the whole future system” without understanding day-to-day reality.

Who runs the software afterward?

We leave it usable for your team. If you want Sentrix to maintain it, we discuss ongoing support separately.
