Custom systems
The tool your operation needs that no off-the-shelf product delivers: records, workflows, permissions and rules specific to your business.
- Records and workflows
- User roles and permissions
- Your own business rules
Custom software development
Web systems and SaaS platforms built for your operation.
AC Alcateia builds custom web systems, SaaS platforms, dashboards and integrations that replace spreadsheets, unify processes and keep up with the company's growth, with your business rules in one place.
- Custom systems and SaaS platforms
- API integrations and automation
- Evolution of existing systems
Signs it is time
When spreadsheets start to get expensive.
Every company reaches a point where improvised workarounds start slowing the operation down.
Data entered twice
The same information typed into different spreadsheets and systems, with rework and errors.
Tools that do not talk
ERP, CRM, payments and spreadsheets in isolation, and reports nobody trusts.
Processes that depend on one person
Rules that only exist in someone's head and stop the operation when that person is away.
What we build
From internal tools to subscription products.
Web solutions with business rules in the right place, isolated integrations and permissions designed from the start.
SaaS platforms
Products sold by subscription: many customers on one platform, plans, access control and an architecture ready to grow.
- Multi-tenant structure
- Plans and access control
- A foundation ready to grow
Dashboards and admin panels
The back office of the people who run the operation, and the numbers now scattered across files, brought into screens your team and management understand.
- Admin panels and back offices
- Operational indicators
- Reports and exports
API integrations
Making what already exists work together: ERP, CRM, payment providers, invoicing and partner APIs, with no duplicate data entry.
- Third-party APIs and webhooks
- Data import and synchronization
- Payments and invoicing
Automation
Repetitive tasks handled by the system: notifications, document generation, checks and routines between tools.
- Scheduled routines
- Automatic notifications
- Document generation
Evolving an existing system
Taking over an application already in use: understanding what is there, stabilizing what breaks and resuming its evolution without stopping the operation.
- Technical assessment
- Fixing what gets stuck
- New features
Benefits
What your company gets
A single source of truth
Data and rules in one place, with history and fewer typing errors.
Time back for your team
Automated routines and integrations instead of manual, repetitive tasks.
The code is yours
The repository belongs to your company and the code is delivered with the project, with no artificial lock-in.
A foundation to grow on
An architecture designed to take on new features, users and integrations without a rewrite at every change.
How we work
From the real operation to a system in use
Understanding the operation
Before talking about screens, we learn where information is created, who depends on it and where the process gets stuck.
Scoping the first version
We start with what brings the most relief. The proposal puts scope and timeline in writing.
Building in cycles
Short deliveries, with the system running in a test environment early, so your team can react while changes are still cheap.
Going live
Data migration, support during the first days of use and ongoing evolution agreed by period or on demand.
Who it is for
A good fit for
Growing companies
Operations that have outgrown spreadsheets and need control, history and permissions.
Software founders
Entrepreneurs who want to launch a SaaS on a solid technical foundation from the first version.
Companies with a stalled system
Applications still in use that stopped evolving or that nobody can maintain anymore.
Technology
Technology and capabilities
A modern, widely adopted stack, so maintenance and talent stay available in the future.
- React
- TypeScript
- Node.js
- REST APIs and webhooks
- GraphQL
- Authentication and permissions
- Cloud and managed hosting
- Automated tests
Why us
Why build with AC Alcateia
Honest recommendations
If an off-the-shelf product solves your case well, you will hear that in the first conversation.
Web and mobile together
If the operation needs an app, it is built on the same rules and design system as the web system.
Documentation and continuity
Recorded technical decisions and readable code, so the system never depends on a single person.
Engagement
How engagement works
- Investment
- Tailored quote. The price follows the complexity of the rules and integrations, not the number of screens.
- Technical assessment
- After the first conversation, which is free, comes the technical assessment, a paid step (R$ 250) that defines the smallest system that already solves the problem and the estimate for the first version.
- Hosting
- On AC Alcateia's infrastructure, with SSL, backups and monitoring on a monthly or yearly plan, or on your company's cloud accounts.
Frequently asked questions
Questions about systems
What is the difference between a website and a web system?
A website presents the company: it is built to load fast, be found on Google and generate leads. A system runs the business: it has logins, records, rules and integrations, and the team uses it every day.
How much does a custom system cost?
It is quoted case by case. A panel that organizes data from one source costs far less than a platform with several user roles and ERP integrations. After the first conversation, which is free, comes the technical assessment, a paid step (R$ 250) that defines the scope and the estimate.
Should I buy an off-the-shelf system or build a custom one?
If a market product fits well, buying is usually cheaper, and you will hear that in the first conversation. Custom software makes sense when the process is a competitive advantage, when no product covers the specific rule or when several subscriptions do not talk to each other.
Can it integrate with our ERP and current tools?
Yes, as long as there is a way in: an API, a database, a web service or file exports. Because the integration also depends on the vendor on the other side, it is evaluated during the assessment.
Does AC Alcateia build SaaS platforms?
Yes. Subscription platforms with many customers, plans and access control, with an architecture designed to grow from the first version.
Who owns the code?
Your company. The repository is in its name and the code is delivered with the project, with documentation so another team can continue the work.
