Your company already knows
how it works.We build the system that follows it.
We build business management software, online stores and automations for companies that already have their own way of working and don't want to change it just to fit a program. First we understand how your operation runs. Only then do we build the system.
Better to hear it from them
Clients we built a system for. With their name, their company and their own voice.

Darío · Logiweb Distribuciones · Translation
Hi, how's it going? Good morning, how are you all? My name is Darío. We have a small distribution company supplying products to shops, called Logiweb. It's a family business that I run with my wife and have for many years now. We know Mateo through his parents. We've been working with them for quite a while distributing their products. Plus our own, which include mobile top-ups, cigarettes, drugstore and perfume products, and so on.
We started working with Mateo. We didn't have a management system, since it was a family business.
We started working with Mateo. It helped us a lot, because it lets us reach our customers in a somewhat more professional way. We were able to grow our customer base in a new way. We stopped using price lists, since we update everything right there. Plus we have the products with photos and prices. We update it right there and customers order there. It really improved the way we work.
As for Mateo, he's always willing to help. Every time we've needed to change something, because the way we work is pretty particular. Because it's a family business. He's helped us, guided us and advised us. He always has a great attitude. So in our case, it's been really beneficial.
Original in Spanish
Hola, ¿qué tal? Buen día, ¿cómo les va? Mi nombre es Darío. Nosotros tenemos una pequeña empresa de distribución de productos para los negocios que se llama Logiweb. Es una empresa familiar que administramos con mi señora hace ya muchos años. Lo conocemos a Mateo por medio de sus papás. Hace bastante que ya trabajamos con ellos distribuyendo sus productos. Y aparte los nuestros, que incluyen carga virtual, cigarrillos, productos de droguería, perfumería, etcétera.
Nosotros empezamos a trabajar con Mateo. No teníamos un sistema de administración, ya que era una empresa familiar.
Empezamos a trabajar con Mateo. Nos sirvió mucho porque se llega de una manera un poquito más profesional a los clientes. Pudimos ampliar la clientela de otra manera. Dejar de usar listas de precios, ya que actualizamos directamente ahí. Aparte de tener los productos con foto, con precio. Actualizamos directamente ahí y nos hacen los pedidos por ahí. Nos mejoró bastante la forma de trabajar.
Con respecto a Mateo, siempre dispuesto. Cada vez que hemos necesitado cambiar algo, porque nuestra forma de trabajar es bastante particular. Por el tema de que es una empresa familiar. Nos ha ayudado, nos ha asesorado, nos ha aconsejado. Siempre está con muy buena predisposición. Así que en el caso nuestro ha sido bastante beneficioso.
Javier · El Paso del Elefante · Translation
Well, my name is Javier, and we're El Paso del Elefante. We're wholesalers and distributors here in Córdoba, covering housewares, hardware and cleaning supplies. Basically, I know Mateo through his father.
We were already running a system in our business, and switching systems is sometimes hard because you get used to one, and our previous system was actually very good, but the proposal and the value Mateo added to our business took it to another level.
Honestly, the system Mateo proposed to us was custom-built from day one, literally tailor-made, covering the needs of the business, from time tracking for the people doing their tasks, to admin and finance, and plenty of other tools too. All of it was custom-built.
What I'd highlight about Mateo is that he's someone who's eager to work, hungry to keep improving, and very smart, and all of that adds value anywhere, when it's simply a system built by him and his team.
Well, we're happy, we're honestly very pleased with the system, because a good system brings us order and organization, and order and organization in a business are the steps before strong, well-managed profitability. Well, all the best. Bye, bye.
Original in Spanish
Bueno, mi nombre es Javier, somos El Paso del Elefante. Somos mayoristas y distribuidoras acá en Córdoba, lo que es bazar, ferretería y artículos de limpieza. Básicamente, a Mateo lo conozco por el papá.
Nosotros ya veníamos trabajando con un sistema operativo en nuestro negocio, lo cual a veces es difícil cambiar de sistema porque uno ya está acostumbrado y aparte el sistema anterior estaba muy bueno, pero la propuesta y el valor que Mateo agregó a nuestro negocio fue superadora.
La verdad que el sistema que nos propuso Mateo el día uno fue un sistema a medida, hecho a talla y a medida literalmente, cubriendo las necesidades del negocio desde control de tiempo de la gente que labura en sus tareas, desde administrativo, financiero, inclusive muchísimas herramientas más. Todo eso fue a medida.
Lo que tengo para destacar de Mateo es una persona con ganas de trabajar, con mucho hambre de superarse, con mucha inteligencia, y todo eso genera un valor agregado en cualquier lado, donde es simplemente un sistema que lo haga él y su equipo de trabajo.
Bueno, nosotros estamos contentos, la verdad que estamos muy felices con el sistema, porque un buen sistema nos trae orden y organización, y el orden y organización en un negocio son las etapas previas a una muy buena rentabilidad bien aplicada. Bueno, saludos. Chau, chau.
None of these screens is a mockup
These are screenshots of systems that are up and running. Where there's a link, go in and see it for yourself.
Localazo
A small shop picks its line of business, enters its details from a phone and that same afternoon has its website live at its own web address, plus the system to run the day-to-day. We built it and we support it.
- The public website and the system, in a single sign-up
- Every shop with its own web address
- Set up entirely from a phone, with nothing to install
MyA Importaciones
A wholesaler that runs its whole day on the system. It sells at the counter and online on its own domain, has more than 2,300 products with photos and variants, and the invoice is issued automatically when the sale closes.
- Counter, online and wholesale sales on the same system
- Payment, shipping and invoice without leaving the sale
- Four resellers, each with its own published catalog
Blussi
An app for adopting rescued dogs and cats where nobody charges anything. You can browse all of it without creating an account: posts with photos, a map of lost pets by province and a direct chat with whoever rescued the animal. We built it and we maintain it.
See it live ↗
El Paso del Elefante
It's finished and running, waiting for its own domain. Each customer logs in and sees the price list assigned to them, with stock in plain view. Behind it is the custom work they asked for: warehouse bin locations (rack and position), tasks with a stopwatch and customer accounts in pesos and dollars.
Automatic catalogs
MyA wanted each of its resellers to have their own online catalog. MyA signs a reseller up and the catalog publishes itself, with the reseller's domain, logo and prices, pulling stock from MyA's system. Four are running today.
See a catalog ↗
Meli automated system
A company that sells on Mercado Libre through several accounts used to log into each one separately. We built them a screen where they see all of them together, with income, profit and margin already calculated and each company kept separate from the others.
Internal business management system
This is how we run Pulso. Every client, their projects, support requests and billing sit on the same screen, and the systems we have running report their status to it. Most of the time we see a problem before the client writes to us.
Evolux
An agency that scales brands on Mercado Libre. We designed and built their website from scratch, made to get people to reach out to them and not just to show what they do.
See it live ↗Logiweb Distribuciones
A distributor with needs that are very much its own: importing the supplier's price list, issuing delivery notes, exporting them to PDF and selling by the half case. We built all of it because they asked for it.
AI assistant
We built it for a client's online store: a chat that answers from their real catalog, with stock, colors, sizes and current prices. If something isn't available, it says so, and it hands the conversation to the salesperson's WhatsApp.
Mobile app
The system's back office, on your phone too. It scans codes with the camera to load stock and make sales, and notifies the owner as soon as an order comes in.
Sneakers Hub
A store we built and rebuilt several times: accounts, roles, cart, stock and tickets. It was the testing ground for what later went into client systems.
Hardly anyone calls us because their system isn't working right. They call because of everything that has to be done by hand around it.
Spreadsheets that only one person updates. And if that person is out, the month doesn't close.
Off-the-shelf software makes you change how you work
You pay for the program and then bend your operation to whatever that program allows. It always ends the same way: half the company inside the system and the other half in Excel.
Nothing talks to anything
The store on one side, invoicing on another, Mercado Libre off by itself. The same sale gets entered three times, and one of the three ends up wrong.
The system is left half-built
It's the complaint we hear most: someone built it, got paid and never came back. We keep supporting the system after we deliver it, and that's already included in the monthly fee.
Four ways to take work off your plate
Custom business management software
Sales · Cash · Inventory · Purchasing · Customer accounts · Role-based permissions
No two are alike. We sit down to see how your company actually operates and build the screens and workflows that operation calls for. If the way you invoice, put together an order or keep track of your warehouse is unlike anyone else's, that is exactly what we program.
AI automation
Assistants · Alerts · Follow-ups · Automatic data entry
Data entry, alerts, follow-ups and replies that someone does by hand today. An assistant can answer with your catalog and your current stock, and hand the conversation to a salesperson when the sale moves forward.
Online stores and websites
Your own domain · Payments · Shipping · Google
An online store or a company website, with your own domain and a design made for you. Payments and shipping already connected, and built so Google can find it.
Integrations
ARCA (formerly AFIP) · Mercado Pago · Mercado Libre · WhatsApp
We connect the tools you already use, and whatever you need later on. The idea is simple: every record is entered once and shows up everywhere.

Hiring a software company shouldn't be scary
This is what working with us looks like, from the first conversation until the system is up and running.
We look at your operation
You tell us what the company does and how you work today. You don't need to know anything technical. From there we find where time is slipping away and what makes sense to automate first.
We send you the proposal
We have no list price, because no two systems are alike. We send you a written quote, with what it includes and how long it takes, before we touch anything.
We build it in stages
We move in short stages, and at the end of each one you see something working, not a report. If the direction needs to change, it changes right there.
We leave it running
We deliver it running and train your people. The system stays yours. After that there's a monthly fee that covers hosting, maintenance and the improvements that come up along the way.
The first conversation is free and doesn't commit you to anything. Write to us and we'll start there.

Custom software from Córdoba, Argentina.
What we solve is concrete: your company's information stops being scattered across spreadsheets, notebooks and three programs that don't talk to each other. Once the workflow is in place, the team stops entering the same thing twice, stock is checked in one place and closing the month no longer depends on someone remembering.
We're a small team, and you can tell by how we work with you: you talk to the people who write the code, not to a middleman. We deliver in short stages, and there's one decision we don't negotiate: staying on after delivery, measuring how the system performs and improving it as the company grows. In Córdoba and its surroundings we meet at your company; with the rest of the country and the world we work remotely.

I handle the analysis of each operation, the architecture it will be built on and making sure the system holds up as the company grows. Then I oversee the team's development work and review everything before it reaches the client.
I'm completing a diploma program in software development, a few courses away from finishing, and I hold twelve certifications, ranging from architecture and performance to quality and cybersecurity. I'm the one who comes to the meeting with your company, not a salesperson.
Nobody knows a business better than the person who runs it every day. My job is to translate that into a system.
What it's built with, plainly
Nobody cares about the names. What follows is what each one changes in your day.
Loads instantly
The store opens fast even on an old phone. People who don't have to wait end up buying.
Nothing breaks
Errors show up before we publish, not when your customer is already checking out.
Grows with you
It's well organized inside, so adding a feature later doesn't break three others.
Your data, safe
Sales, customers and stock are stored the way they should be. Nothing gets lost.
It adapts
When the business changes, changing how the data is stored stops being a headache.
Handles the rush
Lots of people buying at the same time without it slowing down. A big sale day won't take it down.
The rest, for anyone who wants to know: React, Next.js, TypeScript and Tailwind on the side you see; Node, NestJS, Prisma, PostgreSQL and Redis on the side you don't; Capacitor for the mobile app; Railway, Vercel, Cloudflare and Docker to keep it always online.
How we got here
The first client
A website for a roleplay game server, built by hand and delivered on time. That job gave us the one rule we still follow: listen before writing code.
Referrals start coming in
Two more roleplay servers come to us because of the previous year's work, and they are the first projects with integrations: direct purchases with Mercado Pago inside the store. The first development certification arrives too.
The diploma program begins
The diploma program in software development begins, taken alongside the projects and continuing over the next three years. Architecture, performance, quality and security stop being learned on the fly.
The first business management system
Work begins on the complete system a company uses to sell, collect payments and invoice, designed around that company from day one. The training continues in parallel: everything studied goes straight into the project.
51 development stages
Sales, store, point of sale, payments and invoicing. Every piece tested before anyone used it for real.
The first company selling on it
We migrated their entire previous system without losing a single record. They load their full catalog, we train the team and they move over to the new system.
More companies, more custom work
Logiweb comes on board with features of its own, El Paso del Elefante with its warehouse and Evolux with its website.
Two projects of our own
Localazo goes into production, giving a small shop its website and its system in the same afternoon, and so does Blussi, the app for adopting rescued animals where nobody charges anything. Both are ours, and we support them.
Pulso, as a company
What used to be one-person work becomes a company, with a team and several projects running in parallel.
What people ask before we start
What is Pulso?
Pulso (pulsosoftware.com) is a custom software development company from Córdoba, Argentina, working since 2022 and led by its founder, Mateo Valentín Pereyra. We meet clients in person at their premises in Córdoba and its surroundings, and work remotely with companies in the rest of the country and the world.
Do you work in English?
Yes: meetings, email and support in English.
Do you work with companies outside Argentina?
Yes. We meet in person in Córdoba, Argentina, and its surroundings, and work remotely with companies in any country, on Argentina time (UTC-3). Meetings, email and support can be in English. After launch there is also a monthly fee.
What time zone are you in?
Argentina time, UTC-3, all year, with no daylight saving. That is 1 to 2 hours ahead of US Eastern time and 4 to 5 hours behind Spain.
Do you meet clients in person?
In Córdoba, Argentina, and its surroundings, yes: at your premises, and our founder attends himself. Everywhere else we work remotely.
How much does it cost?
We don't have a list price, because no two systems are alike. First we look at your operation, then we send a written quote with what it includes and how long it takes, before we touch anything. The first conversation and the quote are free.
What happens after launch?
We deliver it running and train your team. After that there is a monthly fee that covers hosting, maintenance and the improvements that come up. We stay on, measuring how the system performs and improving it as the company grows.
Can you move the data from our current system?
Yes. In June 2026 we migrated a company's entire previous system without losing a single record; they loaded their full catalog, we trained the team and they moved to the new system.
Is Localazo the same as a custom system?
No. Localazo is our own product for small shops, with its price published on localazo.com.ar. Custom systems get a written quote; we have no list price.

your company needs
Write to us and we'll reply with something concrete. The quote is free: first we look at your operation, then we talk numbers. If your company is in Córdoba, Argentina, the first conversation can happen right there. If you're somewhere else, we hold it remotely.
