What custom software development is

It means building an application around the exact process of a department, instead of bending the process to fit off-the-shelf software or a spreadsheet. Active BI builds custom web systems for departments of mid-sized and large companies: data entry screens, approval workflows, quotes, portals and integrations with APIs, ERP and databases, with artificial intelligence where it saves work.

Because Active BI started in data, every system stores information ready for Power BI. The department assessment is free, the quote is ready within one week and the code belongs to your company, hosted in your environment or ours.

When custom software is worth building

A shared spreadsheet used as a system.

A critical process runs on a spreadsheet that many people edit and no one audits.

The ERP does not cover the step.

Part of the workflow happens outside the system of record, with no history and no rules.

Data entered twice.

The same information is entered in different places, and each version drifts a little.

Approvals by email.

Important decisions are scattered across inboxes, with no traceability.

Examples by department

How it works: from assessment to a system in use

Speed and business knowledge. Fewer requirements meetings, more working software for your team to validate.

01Free

Department assessment

We map the process, the exceptions, who uses it and where each piece of data comes from, talking to the people who run it, not only to those who request it.

02Within 1 week

Fixed-price quote with prototype

You receive the scope, a prototype of the main screens and a fixed price, before any commitment.

03From 1 week

First version in use

After approval, the first version goes into your team's hands, with the essential screens and integrations.

04Ongoing

Evolution in short cycles

Adjustments and new features based on real use, with optional support after delivery.

What artificial intelligence does inside the system

AI works on the operator's screen and takes over repetitive tasks. A person always confirms, and every suggestion is logged.

Evaluate

Candidates, proposals, requests and risks, with the reasoning shown.

Fill in

Fields from documents, emails and receipts, with no retyping.

Write better

Proposals, client replies and announcements in the company's tone.

Summarize

Contracts, histories and long documents in a few points.

Classify

Tickets, expenses and incidents, routed straight to the right queue.

The details, including human control over suggestions, are in AI-Powered Systems.

Power Apps or a custom system?

We do both. Power Apps handles a share of cases very well; a custom system comes in when the process demands more. The choice is made during the assessment, based on your scenario.

CriterionPower AppsCustom system
UsersEmployees already on Microsoft 365Employees, clients, candidates, suppliers and partners
LicensingPer user, predictable for small teamsNo per-user license for end users
User experienceLimited to the platform's componentsScreens designed for the process and for mobile
Built-in AIMicrosoft features, within the platform's limitsAI chosen for each task: evaluate, fill in, write, summarize
Rules and volumeModerate rules and low to medium volumeComplex rules, many exceptions and high volume
When to chooseSimple internal process, team already in the Microsoft ecosystemExternal users, heavy business rules or high license cost

Is your Power Apps app hitting its limits?

Slow performance, formulas no one can maintain or expensive licenses for external users are common signs. We migrate it to a custom system, preserving the data and what already works.

Systems built with data ready for Power BI from day one

Because our systems practice grew out of a data consultancy, every record, approval and activity log is stored in the structure that Power BI and the Data Warehouse will read, with no adjustment spreadsheet in between.

A process that moves off a spreadsheet gets metrics, history and an owner the same day the system goes live.

How much does custom software development cost

It depends on the number of screens and user roles, the integrations, the business rules and how much AI goes into the process. That is why the first step is a free assessment of the department: within one week you receive a fixed-price quote with the scope and a prototype.

Model 1

Fixed-scope application

Price and scope defined in the quote, with the first version in use as soon as one week after approval.

When it makes sense: one clear process in one department.
Model 2

Continuous evolution

A pool of hours for new features, new departments and integrations over time. See plans →

When it makes sense: several processes to move off spreadsheets.
Model 3

Support and hosting

Support, fixes and, if you prefer, the application hosted in the Active BI environment.

When it makes sense: the company does not want to build a team or infrastructure for this.

What drives the investment

  • Number of screens and user roles.
  • Integrations with ERP, APIs, databases and external services.
  • Complexity of the process rules and exceptions.
  • Use of built-in AI and volume of documents processed.
  • External users (clients, candidates, suppliers).
  • Hosting and level of support after delivery.

The code belongs to your company

The system is delivered with source code and documentation. You choose where it runs:

  • In your environment: in the cloud or on your company's servers, under your IT team's policies.
  • In the Active BI environment: we handle hosting, updates and support.
  • Either way, the company can switch providers or take over development internally.

Frequently asked questions about custom software development

What kind of systems does Active BI build?
Custom web systems for business departments: data entry screens, approval workflows, quotes and proposals, job and client portals, supplier quotations, contract management, activity logs and the controls that live in spreadsheets today. All integrated with the company's ERP, APIs and databases, with artificial intelligence where it saves work.
How much does custom software development cost?
It depends on the number of screens and user roles, the integrations, the business rules, the use of AI and the hosting. The first step is a free assessment of the department; within one week you receive a fixed-price quote with the scope and a prototype of the main screens.
How long until the first version is live?
The quote is ready within one week of the assessment. Once the scope is approved, the first version can be in your team's hands in as little as one week, with the essential screens and integrations. The rest evolves in short cycles, based on real use.
Is the assessment free? How does it work?
Yes. We talk to the people who run the process and map the steps, the exceptions and where each piece of data comes from. The outcome is the scope, a prototype of the main screens and a fixed-price quote, with no obligation to hire us.
Who owns the code?
The client company. The system is delivered with source code and documentation, and the company can take over its development internally or switch providers whenever it wants.
Where is the system hosted?
Your choice: in your company's environment, in the cloud or on your own servers, under your IT team's policies, or in the Active BI environment, where we handle hosting, updates and support.
Does the system integrate with our ERP, our APIs and LinkedIn?
Yes. We integrate with SAP, TOTVS, Salesforce, databases, REST APIs, Microsoft 365, SharePoint, LinkedIn, WhatsApp and email, reading from and writing to the source systems when the process requires it. The goal is to avoid entering the same data twice.
What does artificial intelligence do inside the system?
It evaluates (candidates, proposals, requests), fills in fields from documents and emails, writes and reviews texts such as proposals and client replies, summarizes contracts and histories, and classifies tickets and expenses. A person always confirms, and every suggestion is logged.
Is our data protected when the system uses AI?
Yes. The AI works with the system's own data and respects each user's permissions, and we use enterprise AI services that do not use company data to train public models. The security design is validated with your IT team.
Is Power Apps or a custom system the better choice?
Power Apps works well for simple internal processes with users already on Microsoft 365. A custom system makes more sense with external users, complex rules, high volume, AI tailored to the process, or when per-user licensing becomes expensive. We do both, and the choice is made during the assessment.
Do you migrate Power Apps apps to a custom system?
Yes. When an app reaches its limits in performance, formula maintainability or license cost, we migrate it to a custom system, preserving the data and what already works in the process.
Who maintains the system after delivery?
The company decides. We hand over code and documentation for your internal team to evolve, or we take on support and maintenance under an SLA, as we do for data environments and Power BI.
Does the system produce data for Power BI?
Yes. Because Active BI started in data, every record, approval and activity log is stored in the structure that Power BI and the Data Warehouse will read. A process that moves off a spreadsheet has metrics and history from the day the system goes live.
Does Active BI work remotely?
Yes. The assessment, screen validation and deliveries take place in online meetings, with a staging environment for your team to test. We serve companies across Brazil and clients with operations abroad.
