Choosing the right solution
Web application or SaaS platform?
The web application serves the processes of a company. SaaS is a commercial software product offered to multiple customers.
SaaS platform
Onboarding, organizations, plans, subscriptions, billing and ongoing development for multiple customers.
See SaaS development →Internal systems and portals
When a website is no longer enough, you need an app built for the way you work
A web application allows users to log in, manage data, track processes, collaborate, and access different functionality based on role.
We build CRMs, portals, dashboards and operational systems broken down into clear stages so that important flows can be validated before scaling.
Clarification
The difference between website and web application
Some projects combine public presentation pages with a private area for clients, team or partners.
Website for business
Introduce, explain and generate leads
- Company, services and portfolio
- Content, forms and SEO
- Public communication and promotion
Web application
It allows users to work with data and processes
- Authentication and differentiated access
- Documents, statuses and collaboration
- Payments, reports and custom functions
Problems solved
Manual processes and separate tools are time-consuming and error-prone
We centralize data, documents, statuses and collaboration in a system built around real processes.
The goal may be to streamline operations or launch and monetize a digital product.
Fragmented information
Separate files, emails and systems produce duplicates and loss of context.
Unclear permissions
Users do not have well-defined roles, responsibilities and access.
Repetitive operations
Statuses, documents and notifications are tracked manually.
Hard to expand architecture
The existing application does not support modules, integrations or new users.
Suitable for
For companies that want processes, data and responsibilities in one system
From replacing scattered files to customer portals and operating systems.
Fit check
Not every problem requires software built from scratch
Custom development is not suitable when there is already a good standard solution, the process is not clear, there is no product manager or budget for maintenance.
Before development, we analyze whether the project should be custom built, defined as an MVP or solved by integrating existing tools.

- Logging, monitoring and auditing
Staged development
We start with the flow that produces the most value
The first version can centralize the core process, users, data and minimal administration, then expand based on actual usage.
Complete application
It can later add additional modules, automations, mobile app, reporting and integrations.
A first release does not mean untested code, ignored security, or all requirements squeezed into a small budget.
Stage zero
Complex projects start with an analysis stage
Discovery can include workshops, flows, user stories, modules, integrations, risks, wireframes, acceptance criteria and roadmaps.
Process
From problem and MVP to release and continuous development
- Initial discussionProblem, users, goal and budget.
- Analysis and discoveryFlows, data, roles and risks.
- Defining the MVPWe separate the essentials from the next steps.
- Specifications and offerDeliverables, cost and acceptance criteria.
- UX and architectureScreens, interactions and the technical foundation.
- Iterative developmentIntermediate versions and feedback.
- Testing and productionCritical flows, staging and deployment.
- Launch and stabilizationControlled checks and initial support.
Quality and responsibility
Testing, security and operation are planned according to risk
Quality is not just a pre-launch check. It is a responsibility traced from the specification to the operation of the product.
We test the streams that support the product
Unit and integration tests, permissions, payments, APIs, imports, responsive and smoke test in production, adapted to the criticality of the project.
We apply measures appropriate to the data and risks
Authentication, validation, HTTPS, permissions, logs, backup and secret management, without the unrealistic promise of absolute security.
We separate technical implementation from legal obligations
Docodex does not provide legal advice and cannot guarantee GDPR compliance through application development alone.
Indicative packages
Web applications bounded by complexity level
The final estimate is made after clarifying the functionalities, flows, data and integrations.
Web App MVP★

The packages are indicative. Features not included in the offer and supported specifications are not included by default. Infrastructure, processors, email, SMS, storage, external services and licenses are separate costs unless the offer states otherwise.
Estimate and Responsibilities
What influences the price and what the customer must provide
- Users, roles, modules and flows
- Data, Imports, Payments and Integrations
- Security, infrastructure and term
The customer must provide a product manager, access to experts, business rules, test data, feedback and timely approvals.
Requirements arising after specification approval may change the budget and timeline and must be approved separately.
01
Hosting and operation
Recurring costs are separated from development
The application continues to use services after launch. We size infrastructure based on usage and present known costs prior to publication.
- VPS, databases, storage and backup
- Email, SMS, monitoring and logging
- Processors, licenses and external services
02
Delivery
Code ownership and access are established contractually
We explicitly define what is delivered, where the project is hosted and under what conditions the transfer is made after full payment.
- Repository and custom code
- Reusable components and open-source licenses
- Infrastructure, credentials and documentation
After launch
An application needs to be maintained and developed over time
Stabilization covers agreed functionalities. New modules, changes of purpose and interventions caused by external services are estimated separately.
Technology
Modern stack for extensible and maintainable web applications
We choose components based on product, volume, cost, security and development plans. Not all are needed in every project.

What process do you want to turn into a web application?
Describe the problem, users, and main flow. We delineate the first stage and the necessary integrations.
A small and well-defined web application can start from €2,990 + VAT. The final cost depends on modules, users, roles, data, automations, integrations, security and infrastructure.
A small project may require approximately 30–50 working days. Applications with multiple modules or integrations are estimated after discovery and typically delivered in stages.
It is the stage where we clarify the problem, users, flows, data, integrations, risks and priorities before estimating the implementation.
It is the first working version that solves the problem and the main flow. It doesn't mean sloppy code, ignored security, or crammed all the features into a small budget.
Yes, after mapping data, validations, responsibilities and exceptions. Sometimes the right solution can be an integration, not an application built entirely from scratch.
Yes. We can implement customers, contacts, activities, opportunities, documents, statuses, notifications and reports adapted to the company's process.
Yes. The portal may include accounts, documents, requests, statuses, payments, communication and differentiated access.
Yes. The web interface is responsive. If use requires native features, push notifications, or distribution through app stores, the mobile app is priced separately.
Yes, if the services provide compatible APIs, webhooks, or exports. Feasibility and limits of integration are checked before bidding.
Yes, after analyzing the data structure and quality. Cleaning, mapping and complex migration are estimated separately.
We define what each type of user can see and change, then implement and test rules for critical flows.
We use manual and automated risk-based testing, staging, code review and acceptance scenarios for important features.
We apply project-appropriate measures: authentication, authorization, validation, HTTPS, logs, backup and updates. Absolute security cannot be guaranteed.
The repository, custom code rights, reusable components and transfer conditions are set out in the offer and contract.
Setup may be included, but VPS, storage, email, SMS and other recurring costs are separate unless the offer states otherwise.
