Solution 02 · Custom systems, portals and SaaS

Custom systems, portals and SaaS built for your real business process.

CRMs, ERPs, B2B portals and SaaS platforms built with a modern stack, precise data modeling and UX that teams actually adopt.

API

Integrations with existing systems

We connect the new system to the tools you already use via REST, webhooks and n8n automation.

SaaS

Architecture ready to scale

Multi-tenant, granular permissions and modules that evolve without rewriting the platform core.

UX

Interface the team actually adopts

Functional design, flow aligned with the process and onboarding that reduces internal resistance.

Business problem

Spreadsheets, generic tools and disconnected systems block operational growth.

Growing companies reach a point where available tools no longer fit the real process. The result is rework, fragmented data and teams operating outside the system.

01

Manual processes that do not scale

What works in spreadsheets or a generic CRM creates bottlenecks as operation volume increases and the team grows.

02

Systems the business works around, not with

Generic tools force the company to adapt to the software. The result is parallel processes outside the system.

03

Fragmented data with no unified view

Information scattered across ERPs, CRMs and spreadsheets prevents fast decisions and reliable reporting.

What we deliver

A system built from the company's real process, not a template.

The solution starts with business process mapping. We build systems that fit the operation, integrate existing channels and scale with growth.

Custom system or portal with process modeling

We map business rules, flows, roles and permissions to build a system that reflects how the company operates — with an interface the team adopts without resistance.

SaaS platform or scalable MVP

For startups and companies launching a digital product: SaaS architecture with multi-tenancy, authentication, billing and modules ready to grow without rewriting the core.

Use cases

Where this solution usually creates the most impact.

Custom commercial CRM

For sales teams with pipeline, customer history, follow-up automation and reports aligned to the real commercial process.

B2B portal or client area

For companies that need structured access for clients, partners or suppliers with approvals and centralized communication.

Simplified ERP for operations

For companies that need to unify finance, inventory, orders and team in a single platform without enterprise complexity.

SaaS platform MVP

For startups that need to validate their business model with a functional, secure product ready for the first paying customers.

How we implement

From process mapping to deploy with focus on real adoption.

Step 01

Process mapping and business rules

We map flows, roles, exceptions and required integrations before writing a single line of code.

Step 02

Data modeling and technical architecture

We define the data model, technical stack and structure that allows growth without rewriting.

Step 03

Incremental development with weekly deliveries

We build in short cycles with real demos, team feedback and continuous adjustments.

Step 04

Deploy, documentation and continuous evolution

We deliver to production with technical documentation, training and an evolution plan for new features.

Stack and technical scope

Modern technology oriented to maintainability and scale.

Each system is built with the appropriate stack for the context: performance, security, integration and the ability to evolve without accumulating technical debt.

  • Next.js, React and Node.js with TypeScript — modular architecture and strict typing
  • PostgreSQL and Prisma with data modeling oriented to the business process
  • Authentication, role-based permission control and audit of critical actions
  • Integrations via REST, GraphQL, webhooks and automations with n8n
  • Dashboards, reports and real-time data export
  • Cloud deploy with CI/CD, error monitoring and continuous technical support

What makes the approach different

We do not deliver code. We deliver a system the team uses and the business trusts.

The difference between a well-built system and an abandoned one lies in process modeling, interface quality and alignment with those who use it daily.

Application example

B2B management portal with financial dashboard and order control

A service company needed to replace spreadsheets and emails with a centralized portal. We delivered an orders module, financials, approvals and role-based access — with 100% team adoption in 30 days.

  • Architecture ready for new features without rewriting the core
  • Interface aligned to the real process, not a generic template
  • Native integrations with tools and channels already used by the team
  • Source code, technical documentation and support included in the delivery

Frequently asked questions

Common questions before starting a custom system project

What is the difference between a custom system and a generic SaaS?

A generic SaaS solves 80% of cases through configuration. A custom system is built exactly for your company's process — with the rules, flows and integrations that make sense for your business. The choice depends on process complexity and how much it is a competitive differentiator.

How long does it take to deliver a system MVP?

A functional MVP with core features can generally be delivered in 4 to 10 weeks. Simpler systems (portals, basic CRMs) are closer to 4 weeks. SaaS platforms with billing and multi-tenancy, closer to 10 weeks.

Can the system grow with the business without rewriting everything?

Yes, as long as the initial architecture supports that growth. We build with module separation, extensible data modeling and well-defined APIs so new features can be added without impacting what is already in production.

How much does it cost to develop a custom system?

The investment depends on scope, number of modules and integrations involved. Lower-complexity projects start at a lower cost; full SaaS platforms require proportional investment. We offer a free technical diagnosis to present a proposal with detailed scope and estimate.

Do you deliver the source code and technical documentation?

Yes. The client receives the full source code, technical architecture documentation and full access to the repository. There is no lock-in: the project is yours and can be evolved by any future technical team.

Next step

If your process demands more than a generic SaaS delivers, this is the right foundation to start.

We map the process, assess the technical scope and deliver a proposal with stack, timeline and investment — no commitment required.
