Custom Software

Custom Software:
your process turned into your own system.

When no off-the-shelf software fits how your company works, we build yours. With functional requirements, UAT and code delivered as your property.

  • Requirements gathering with your key users, acceptance criteria and UAT before go-live.
  • The code is yours: 100% intellectual property transfer, with repository and documentation included.
  • Post-delivery warranty and optional monthly maintenance plan to evolve the system.

Qualification

Is this service for you?

Filter before you move on. If your company sees itself in any of these signals, keep reading. If not, we will point you to a better-fit service.

It's for you if:

It's for you if:

  • Your company has unique processes that no standard system covers, and today you manage them in Excel, paper or scattered tools.
  • You have an ERP that covers the accounting basics, but there are proprietary processes left out and you resolve them by hand.
  • You know what you need to build (or what the problem is), but haven't found anyone who'd do it seriously.
  • You can commit your key users to requirements gathering sessions and UAT.
  • You want to own your system, not rent a generic tool.
It's not for you if:

It's not for you if:

  • What you need is implementing AI or automations over existing processes without building new software. That's Operational AI
  • You're looking for a quick, cheap prototype without a requirements process. Building without validation has high risk; we don't operate that way.
  • You need a mass-consumer app or SaaS to sell. That's product development; different logic.
  • You can't commit your key users' time. Without that, the system reflects what we imagine, not what your company needs.
Diagnosis

What is your starting point?

Almost every company arrives from one of these two points. The process adapts to yours.

Point A

Build from scratch

There's no system covering the process. Today you manage it in Excel, paper, emails or scattered tools. It works while the volume is low and the person who maintains it is available.

Signals:

Critical process on a spreadsheet only one person knows how to maintain.As volume grows, errors multiply.Information not centralized (each area has its version).If someone touches the wrong file, the process breaks.
Point B

Extend what you already have

You have an ERP or other base software covering the standard processes. But there are proprietary flows the system doesn't contemplate, and you resolve them in parallel, by hand or with loose tools.

Signals:

ERP that covers accounting, but not how purchase orders get approved or field inventory gets controlled.Reports that cross data from multiple sources and get consolidated by hand.You need screens or validations the ERP vendor didn't build.Unique processes that need rules, permissions or traceability the base system doesn't have.

In both scenarios, the first step is the same: a requirements gathering that turns your operation into technical specification. There we define what to build first, what stays out of initial scope and what criteria determine the system is right.

Delivery formats

The systems we build.

Three main formats. The build process is the same for all three.

01

Internal web application

the most frequent

For: Companies replacing Excel, paper or manual processes with a controlled system.

Typical cases: Logistics control, approval flows, operational traceability, cross-area consolidation, planning, request management.

By browser, no installation, with permissions by user.

02

Complementary module to existing system

For: Companies with an ERP or other base system that need to extend it with processes the vendor didn't contemplate.

Typical cases: Specific approval modules, management reports with data from multiple sources, controlled integration via API.

We don't replace what works; we complement what's missing.

03

Portal or reporting tool

For: Companies extending operations toward clients, suppliers or management with analytics.

Typical cases: Request portals for third parties, management dashboards with live indicators, document systems with controlled access.

Dashboards get built when the underlying data is reliable. We don't promise reports on dirty data.

Clear limits

What this service is not.

Clear limits prevent misunderstandings. These scopes are not part of the base plan.

24/7 support by default

SLA and hours are defined from the start. Extended availability is quoted as an additional agreement.

Unlimited features inside the project

Development is governed by approved scope. Scope changes are managed as additional phases.

Massive historical data migration

Not included by default. If your project requires it, it's quoted and planned explicitly.

Integration with legacy ERP without API

We connect systems with standard interfaces. Without an API, we define an honest strategy in the requirements phase, not promises the infrastructure can't deliver.

Extended training for the whole company

We include specific onboarding and documentation. Mass training is quoted separately.

Third-party licenses

If the system needs external tools with licensing costs, they're quoted separately or you acquire them directly.

Method

The phases of the project.

Each phase with a concrete deliverable and progress criteria. We don't move to the next without validating the previous one.

Phase 0

Functional Requirements

Sessions with the sponsor and your key users. We map the current flow, define rules, exceptions, permissions and input/output data.

Functional spec + scope + acceptance criteria + prioritized backlog + flow map.

Phase 1

Architecture and Technical Design

We define technologies, database, deployment (cloud or on-premise), integrations and security structure. You don't need to understand the details; you do need to make the business decisions: where your data lives, who has access, how it scales.

Documented technical decisions + refined effort estimate per module.

Phase 2

Iterative Development

We build by modules with internal reviews before each presentation. We don't deliver everything at the end; we deliver functional parts for incremental validation.

Functional modules per iteration + change log + test environment.

Phase 3

QA + UAT

Internal QA verifies the system meets the spec. Then UAT with your key users, guided by the Phase 0 acceptance criteria. It's not "try it out and see"; it's formal validation with real scenarios.

QA report + signed UAT minutes as go-live condition.

Phase 4

Go-Live + Warranty

Production deployment, specific onboarding with your key users and initial monitoring.

System in production + technical and user documentation + repository transfer.

Optional Phase 5

Monthly Maintenance

Minor fixes, functional improvements, technical updates and support for operational contingencies.

Base bucket of 10 hours/month, adjustable. Available after go-live and the 30-day warranty.

Tech stack

Who builds it and with what.

Technology selected by project context, not by vendor preference. If your IT team works with a different stack, we evaluate it in the requirements phase.

Fullstack developers (frontend + backend integrated)Backend (APIs, business logic, integrations)Frontend (operational interfaces and usability)DBAs (data modeling, performance)QA engineers (functional and regression testing)DevOps / infrastructure (deployment, CI/CD, monitoring)

In practice

What we build, in concrete cases.

Three frequent patterns. Your case gets defined in the requirements phase.

The critical process that lives in Excel

Situation

Production control, planning or product traceability managed in spreadsheets. It works at low volume; as the team grows, it scales badly and depends on one person.

System built

Internal web app with the digitized flow, data entry with validations, roles by function, traceability of every action and live reports.

How it operates

Your team works from the browser. The rules live in the system, not in the memory of whoever maintained the file.

The ERP that doesn't cover everything

Situation

ERP that handles accounting and standard stock. But the approval flow has tiers by amount and area, the reports cross several modules and internal requests live in email.

System built

Complementary module integrated via API, with configurable tiers, consolidated reporting and requests with statuses and owners.

How it operates

The ERP keeps doing its job. The module covers what was missing, connected to the existing data.

The portal that connects outward

Situation

Requests from clients or suppliers arrive through email or WhatsApp. The status is known internally; the external party has no way to check it.

System built

Self-service portal with authentication. The external user logs in, checks status, downloads documents and receives notifications. Your team administers from the same system.

How it operates

Clients query directly. Your team stops answering status questions and focuses on requests that need attention.

These patterns combine or extend. What doesn't change: serious requirements, phased development, formal UAT and code delivered as your property.

Investment

Investment and project model.

We publish the reference price. The exact cost gets closed in the requirements phase.

Build + delivery

Requirements + build + delivery

From $2,500 USD + IVA

Covers functional requirements, technical design, phased development, QA, UAT, go-live, documentation and code transfer. Payment model: by project milestones (down payment, partial deliveries and go-live). Not all charged upfront.

Monthly operation

Monthly maintenance (optional)

Monthly fee per agreed scope

Base bucket of 10 hours/month, adjustable: improvements and tweaks, 8×5 support and basic monitoring. More hours, differentiated SLAs or specific coverage are quoted case by case. Available after go-live and the 30-day warranty.

The fee varies by complexity: modules, flows, integrations and technical requirements. We define it in the requirements phase with clear acceptance criteria before committing budget.

Tell us the process you need to systematize and we'll guide you on scope and estimated cost.

Frequently asked questions

What the CEO and their IT team ask before starting the project.

Is the code mine?
Yes. Total intellectual property transfer: code, repository and documentation are yours from delivery. You can modify it or continue with another vendor.
What if I want to change vendors in the future?
Designed for that. We deliver the repository with version history and complete technical documentation. Any qualified team can pick it up.
How do we validate that the system turned out right?
With the acceptance criteria defined in Phase 0, before the first line of code. UAT is formal validation with real scenarios. If it passes, it goes live. If not, it gets fixed.
What does the warranty cover and not cover?
Covers bug fixes within delivered scope during 30 days post go-live. Doesn't cover new features, requirement changes or errors from third-party modifications.
What does monthly maintenance include?
Base bucket of 10 hours/month for improvements and tweaks, 8×5 support and basic monitoring. More hours or different SLAs are quoted case by case. Unused hours don't roll over.
Can it be integrated with my ERP or existing system?
Yes, if it has documented APIs. Integrability is evaluated in the requirements phase. Without an API, we define an honest strategy before committing scope.
On-premise or cloud?
Depends. Cloud (AWS, Azure) is more agile and scalable; recommended for most. On-premise makes sense with strict policies or established internal infrastructure. Defined in Phase 1.
How much time do we have to dedicate?
Participation at specific moments: 3 to 6 requirements sessions, validations per module during development and UAT at the end. If validations take time on your side, the calendar adjusts.
Can this be integrated later with Operational AI?
Yes. It's the natural evolution. First the stable system with clean data. On top of that, Operational AI enters without friction: automations, assistants and analysis on the generated data.
What if I change my mind during development?
Minor changes within the spirit of the requirements get absorbed. Relevant changes get evaluated as additional scope with impact on time and cost. Nothing changes without written agreement.
Is this different from Operational AI + Automation?
Yes. Here we build proprietary software from scratch or as a new module. Operational AI implements AI and automations over existing processes with off-the-shelf platforms, no proprietary code.
What countries do you operate in?
Based in Ecuador. We operate remotely for companies across Latin America. 100% digital, with standard collaboration tools.

How much longer will you manage
that process in Excel?

The first step is the functional requirements phase. In that conversation we define what to build, what stays out of initial scope and what criteria determine the system is right, before committing budget.
