In-house products

We don't talk about engineering. We show what we built.

Vita Munhoz Tecnologia builds custom software — and its own products too. These are the systems we designed, built and maintain from scratch. All three are in development and validation: what we show here is engineering that exists, not a product on sale.

3 in-house products in validation · Architecture, development and improvement done in-house

Those who build, show

An in-house product is the most honest way to prove technical capability

Describing competence on a services page is easy. Building a real product is harder, and far more revealing: an architecture that has to scale, flows that have to work and decisions that age well. The three products below are in development and validation — what we show here is what has already been built.

A real product, not a demo

Every product here started from a real problem, was architected from scratch, and is kept in continuous improvement by our team.

The same engineering we deliver

The architecture, security and experience decisions we apply to our own products are the same ones we apply to client projects.

Custom-built work too

Beyond our in-house products, we build solutions on demand — apps, enterprise systems, websites and AI — for companies of different sizes.

Mobile App · Personal Finance

Fin — Personal Finance Management

Your money on your device. No subscription, no ads, no mandatory cloud.

In-house productPre-launch · Android

Executive summary

Fin is a personal finance app built by Vita Munhoz Tecnologia. The Android version is implemented and in validation, ahead of its public launch. It brings together the complete core of a finance manager — transactions, cards with statements assembled automatically, accounts, investments, savings goals, budgeting, a monthly dashboard and reminders — in a mobile experience designed for daily use. Two architectural decisions define the product. The first is being offline-first: everything works without an internet connection, and the cloud is a convenience, not a requirement. The second is treating privacy as a feature rather than a promise: the local database is encrypted, the key lives in the operating system's vault, receipt scanning happens on the device, and the AI assistant only ever receives an aggregated summary — never the raw transaction list. The commercial model planned for launch closes the argument: a one-time purchase on Google Play, with no ads, no subscription and no data selling.

Managing your own money is still too much work

  • Spreadsheets demand manual discipline and fall apart in the first busy week.
  • Free apps are funded by advertising — which puts them at odds with anyone trying to spend less.
  • Many of the alternatives charge a recurring subscription for basic features.
  • Apps that centralize financial data on their own servers widen the exposure of sensitive information.
  • And without an internet connection, most of them simply stop working.

Who it's for

  • People who want to see and control their own spending
  • Anyone organizing a budget or working their way out of debt
  • Anyone who will not accept a subscription or ads inside a finance app
  • Anyone who puts privacy first and does not want financial data on third-party servers

Key features

What is already implemented in the version under validation.

Full transaction types

Expense, income, transfer between accounts and installment purchase — scheduled or settled.

Receipt scanning (OCR)

The camera reads the receipt and pre-fills the entry. The photo never leaves the device.

Cards and statements

The statement is assembled automatically per cycle, with used and available limit in real time.

Accounts and net worth

Checking, savings, cash and investment accounts, with consolidated net worth.

Budget by category

A monthly spending target that shows what is left — or by how much you went over.

Savings goals

Progress tracked by hand or mirrored from an account balance, with contributions and a target date.

Investments

Fixed income, stocks, funds, REITs, crypto and savings, with returns calculated for you.

Monthly dashboard

Income, expenses, what is left over and a donut chart by category, month by month.

Due-date reminders

Local notifications for scheduled bills and card statements, overdue ones first.

AI assistant

Ask in plain language. It answers from an aggregated summary — and it is the only feature that needs an internet connection.

Backup and import

Export and import a JSON backup; import transactions from a CSV file.

Manual sync

You decide when to sync. Until you do, your entries never leave the device.

Encrypted local database

The data is encrypted on the device, with the key held in the system vault.

SaaS · Restaurant Operations

Totem Lanchonete

The restaurant's entire operation, end to end, in a single box.

In-house productIn development

Executive summary

Totem Lanchonete is a SaaS platform built by Vita Munhoz Tecnologia for quick-service restaurants, burger joints and small food service operations — the most fragmented and least digitized segment of eating out. Instead of requiring a computer, a technical installation and a local server, the customer receives a kit that is ready to operate: a tablet that works as checkout and admin console, a thermal printer for the kitchen, and access from the staff's own phones. The waiter enters the order on a phone, the kitchen receives it immediately on the printer, the checkout closes the day with automatic reconciliation, and the owner tracks product ranking, average ticket and peak hours in real time. It is 100% cloud-based, with continuous updates and no technician on site.

Restaurants still run on paper and memory

  • Paper order tickets cause wrong orders, rework and lost sales.
  • Closing the register by hand hides shortfalls and losses.
  • The owner has no visibility into best sellers, margin or peak hours.
  • Traditional systems require a computer, a technical installation and a high upfront cost.
  • Generic POS solutions do not speak the language of a restaurant counter.

Who it's for

  • Quick-service restaurants and burger joints
  • Small and midsize food service operations
  • Venues that still run on paper order tickets
  • Owners who need management without depending on a technician or a local server

Key features

What is already implemented in the version under validation.

Digital order ticket

Waiters enter orders on their phones; the kitchen receives them instantly, printed on the thermal printer.

Connected kitchen

The order goes straight to production, with no middlemen and no paper lost along the way.

Checkout and POS

A dedicated tablet with automatic closing, cash drops, payment methods and reconciliation.

Management and reports

Product ranking, average ticket, peak hours and margin per item in real time.

100% cloud

Automatic, continuous updates — no technician on site and no physical server.

Plug & play

The tablet and the printer arrive ready: turn them on, connect to Wi-Fi and start selling.

Mobile App · Service Business Management

CaixaMEI AI

The service provider's financial copilot: from the quote to the money in hand.

In-house productIn development

Executive summary

CaixaMEI AI is a mobile app built by Vita Munhoz Tecnologia for service providers, self-employed professionals and micro-entrepreneurs — the professional who quotes, works and gets paid from their own phone. Instead of starting from accounting, it organizes the journey they already live every day: send a professional quote, record the approval, track the job with its costs and attachments, bill with a deposit and installments and, at the end, see the real profit of each job — not just what came in. Artificial intelligence steps in where it cuts work and improves a decision: it suggests the price structure and flags when costs or margin look off, but the final word always stays with the user. It is a light experience, designed to handle everything on the device, without the complexity of an ERP.

The revenue shows up. The profit disappears.

  • Pricing is done from memory — material, travel, hours and margin estimated without a method, which compresses profit.
  • The operation is scattered: the request on WhatsApp, the quote in a text message, the receipt in the photo gallery and the billing in someone's head.
  • Deposits, installments and pending balances have no reliable tracking and turn into forgotten money.
  • The professional knows how much came in, but not how much was earned after every cost.
  • Personal withdrawals and expenses mix with the business and distort the financial picture.
  • Traditional ERPs are far too complex for someone who needs to handle everything on their own phone.

Who it's for

  • Service providers, self-employed professionals and micro-entrepreneurs who quote and bill from their phone
  • Electricians, installers and maintenance and repair professionals
  • Painters and staged jobs, with material and labor
  • Photographers and creatives who work with deposits, delivery and installments

Key features

What is already implemented in the version under validation.

Professional quote

Client, line items, material, labor, validity and a PDF with the business's identity.

AI pricing

Suggests the price structure and flags a thin margin — the decision is always yours.

Recorded approval

The acceptance is logged and the approved proposal is kept as an immutable snapshot.

Work order

Checklist, attachments, costs and job progress in one place.

Billing and Pix

Deposit, installments, due dates and reminders — with no forgotten money.

Receivables

Deposits, installments and pending balances tracked through to settlement.

Profit per job

Revenue minus material, travel, fees and the other costs you record.

Monthly result

Profit, margin, average ticket and quote-to-job conversion.

Personal and business apart

Personal withdrawals and expenses don't distort the business's financial picture.

Proposal with your brand

A PDF with your identity, terms, versions and sharing in a few taps.

How we build

What holds up a product that has to last

These are not showroom adjectives. They are the engineering decisions visible in the three products on this page — and in the projects we deliver to clients.

Modern architecture

Structural decisions made to last: the product has to survive its second year, not just its first release.

Cloud ready

Applications built for the cloud — scaling means provisioning, not rewriting.

Artificial intelligence

AI applied where it solves a real problem: automatic categorization, demand forecasting, assistants.

Product UX/UI

Interfaces designed for the real context of use — the restaurant counter and the phone in your pocket.

High performance

Fast applications by design, not by last-minute optimization.

Security

Data minimization, encryption and access control from the architecture onward.

Clean code and SOLID

Code the next person can read, understand and evolve without fear.

Clean Architecture

Business rules isolated from framework and infrastructure — replaceable without surgery.

Integrations and APIs

Systems that talk to the client's ecosystem instead of becoming an island.

Automation

Manual, repetitive processes removed — from deployment to day-to-day operation.

Process

From discovery to continuous improvement

The same path we walk through in our own products is the one we apply to every client project. No stage skipped.

  1. 01

    Discovery

    Understand the real problem, the user and the business constraint before proposing a solution.

  2. 02

    Planning

    Scope, priorities and success criteria defined with clarity.

  3. 03

    Architecture

    Structural decisions that support evolution — not just the first release.

  4. 04

    UX/UI

    Interfaces designed for real use, on the device and in the context of the person using them.

  5. 05

    Development

    Clean, component-based, testable code, shipped incrementally.

  6. 06

    Testing

    Functional, edge-case and regression validation before any release.

  7. 07

    Deployment

    Releases with a predictable, versioned and reversible process.

  8. 08

    Support

    Follow-up after go-live, when the system meets the real world.

  9. 09

    Continuous improvement

    Measure usage, fix what gets in the way and evolve what delivers results.

Technology stack

The technologies VM Tecnologia knows and uses, in its own products and in client projects. The choice of stack always follows from the problem — never the other way around.

The next product on this page could be yours

We build our products from scratch — from discovering the problem to the architecture, the code and the continuous improvement. That is exactly the process we make available to companies that want to turn an idea into a digital product that works, scales and lasts.
