Custom SaaS & Web Apps

We design and develop custom internal tools, customer zones, B2B/B2C portals, and SaaS products. When your process cannot fit into a ready-made system, the software is built around how your team actually works: custom roles, data, calculations, approvals, and integrations.

Without process digitalization

Excel, emails, and boxed tools stop being enough as you grow

As a team grows, manual data entry, shared spreadsheets, and bypassing the system begin to slow down work. Information is scattered across emails, processes rely on specific people, and systems don't communicate with each other. The result is errors, slow approvals, and a weak overview of what's happening in the company.

Error rates

Manual data entry between systems introduces human error.

Poor scalability

A process that works for a smaller team starts to break on exceptions as it grows.

Frustration

Customers, partners, or employees must call and email instead of handling things themselves.

Solving the problem

Custom CRM or portal

A system tailored to your business processes, roles, and exceptions without unnecessary modules.

Automated reports

Dashboards and overviews instead of manually compiling Excel spreadsheets. Management sees key data faster.

Scalable architecture

Database, API, and permissions are designed to handle more users, data, and integrations over time.

Your Process, Your Software

Boxed solutions often force a working business to adapt to their limitations. Custom software should do the opposite. It can be a manufacturing calculator, fleet reservation system, customer zone, or B2B portal with multi-level approvals. The project starts by mapping real processes, so development follows how your team actually works rather than assumptions.

What we typically build

01
Customer and partner zonesSelf-service portals for customers, partners, or vendors connected to billing.
02
Internal ERP and CRM modulesTools for employees that reduce manual data entry and repetitive administration.
03
SaaS platformsUnique know-how translated into software you can sell as a monthly subscription.
04
Process auditsFirst we map decisions, exceptions, and approvals, then we design the database and screens.
Process

How we build SaaS products

01

Processes
and data models

Roles, exceptions, approvals, and database structures are mapped before development.

02

Core
API

The application core covers calculations, permissions, and connections to external services.

03

UI/UX
implementation

A clear React or Next.js interface is built around the application type.

04

Beta
and development

The first version launches for selected users, feedback is collected, and the roadmap is refined.

Our standard

We build the core, not just screens

If you need a simple prototype or an internal form, a no-code tool might be a good start. We step in where a process already requires a custom database, access rights, complex calculations, integrations, or long-term maintenance. Production code is more expensive initially, but it provides greater control over security, scaling, and future development.

Preparation for growthWe design the architecture according to the expected number of users, data volume, and integrations.
03
Technical supportWe provide SLA maintenance and monitoring even after going live.
04
User adoptionWe don't just solve code. We track whether the system actually saves time for the people who work in it.

Upon completion of development and payment for the project, the source code can be transferred to you under contractually agreed terms. We do not tie you to a closed platform or rent you someone else's software.

Yes. For SaaS or B2B portals, we can design the architecture so that data for individual clients, partners, or branches is separated via access rights and database rules.

We use proven approaches such as authentication, password encryption, access roles, audit logs, and depending on the architecture, Row Level Security directly at the database level.

Before development, we map real workflows, roles, and exceptions. We put early versions in users' hands as soon as possible so the product is shaped by practice, not an abstract specification.
