Digital transformation · Tandil

Digital transformation agency in Tandil, Argentina: Systems that already work in businesses like yours.

We design software, automate processes and connect the tools you already use. For businesses and for people, from Tandil.

Tell us which process you want to improve.

The problem

Your business shouldn't depend on manual tasks.

Invoicing, appointments, stock, collections, follow-up and internal management usually end up scattered across spreadsheets, WhatsApp and tools that don't talk to each other.

Serra connects those processes and builds the software that's missing.

01 · Products

Software that is already running.

We don't sell ideas. We build products that work every day, with their own brand and domain.

Digital Transformation

Custom technology consulting

Together with your company or organization we assess how to make the technological leap you need: what to digitize first, what to automate and which systems to connect, always from a technology perspective and adapted to your reality, not to a generic recipe.

  • Diagnosis of current processes and tools
  • Prioritized digitization plan
  • Recommendation on what to build, buy or integrate

Who it's for: Companies and organizations that need a clear direction before investing in technology.

Web Development

Landing pages, websites and custom applications

From landing pages for businesses with no online presence yet to complex platforms with users, payments and their own business logic. Every site is built to rank well on Google and turn visits into real customers, with CTAs built into each section.

  • High-end landing pages with 3D details and conversion CTAs
  • Web applications with authentication, panels and dashboards
  • E-commerce and online stores with integrated payments
  • Portals for customers or employees, with roles and permissions
  • Full QA on mobile and desktop before every delivery

Who it's for: Businesses with no online presence and companies that need their own web system.

Mobile Development

Native and cross-platform apps

We develop mobile applications for iOS and Android, native or cross-platform, connected to the backend you already have or one we build from scratch.

  • Native or cross-platform apps (React Native / Expo)
  • Push notifications, in-app payments, GPS and maps
  • Camera, QR scanner and access to device hardware
  • Publishing on the App Store and Google Play

Who it's for: Delivery, appointment management, field operations control, customer loyalty.

Process Automation

n8n and integrations between systems

We automate the repetitive work someone does by hand today, connecting the tools you already use so information flows on its own, with no copying and pasting between systems.

  • Order in your store → created in logistics and notified on WhatsApp
  • Appointment booked → created in the calendar, confirmed by email and logged in the CRM
  • Automatic synchronization between spreadsheets and management systems
  • Reports that generate themselves and arrive by email or WhatsApp

Who it's for: Any company with manual processes scattered across spreadsheets and tools that don't talk to each other.

Custom IoT

Software and hardware working together

Cameras, sensors and a system that measures, analyzes and shows what is happening in your shop, plant or field. We adapt to the industry and the problem: first we understand what you need to know or control, then we choose the hardware and build the software that turns it into decisions.

  • Cameras, sensors and meters integrated into a single system
  • Real-time dashboards, also multi-site
  • Detection of spikes and anomalies, with alerts by WhatsApp or email
  • Automations on what is measured: cut-offs, switch-ons, notices, schedule rules
  • In-house prototyping in electricity consumption, ready to adapt to your case

Who it's for: Any industry that needs to see, measure and act on what happens in the physical world: shops, industry, agriculture, buildings.

Your Company's Brain

Documentation vectorization · self-hosted

We turn your company's documents, manuals and processes — information that doesn't change every day — into a knowledge base an AI agent can query. Designed for companies with a lot of confidential documentation: everything is hosted on the client's own infrastructure, never in a third party's cloud.

  • Ingestion of thousands of documents (PDF, Word, Notion, Google Docs)
  • Vectorization with semantic embeddings
  • Self-hosted vector database with Qdrant, on the client's VPS
  • An agent that answers questions about those documents in natural language

Who it's for: Companies with lots of documentation (manuals, internal processes) that cannot leave their infrastructure.

Real-Time Data Agents

Live queries, not frozen information

Unlike Your Company's Brain, here the agent doesn't read static documents: it queries live the information that changes all the time — stock, sales, appointments, any database or API — and answers in natural language, like having an on-demand PowerBI through chat.

  • Connection to SQL, BigQuery, Google Sheets, REST APIs or CSV/Excel files
  • Our own MCP (Model Context Protocol) servers to expose your internal tools securely
  • Agents that can also take actions (log an order, look up a customer), not just read
  • For example: ask in chat which appointments are free today or how much stock there is of a product, and the agent checks it live

Who it's for: Companies that need instant answers about data that keeps changing.

Is your case not on this list? Tell us anyway: it's almost always a combination of two.
