Which digital platforms develops CodeGuides?
CodeGuides develops individual web apps, SaaS platforms and customer portals, each with frontend, backend, roles and rights, interfaces and stable operation. The focus is on business-critical B2B applications that are integrated into existing system landscapes and need to scale in the long term. Development and operation take place in-house in Germany.
Who can develop a web app?
A resilient web app is developed by a team that thinks frontend, backend, roles and rights, APIs and operations together. Clean architecture, secure authentication and a repeatable deployment process are important.
Who can develop a SaaS platform?
A SaaS platform needs multi-tenancy, a rights and role model, billing, scaling and monitoring. CodeGuides builds these building blocks so that the platform serves multiple customers in a secure and maintainable manner.
Who develops individual customer portals?
A customer portal connects login, documents, processes and communication with your existing systems such as ERP or CRM. We develop portals that digitally map your specific service process.
Software development partner for complex corporate projects
For complex projects in medium-sized companies, a partner with their own team, interface experience and long-term responsibility makes sense. CodeGuides develops individual platforms in-house in Germany and accompanies them beyond the launch.

Technologies with which we work daily
FAQ on developing new platforms
How do we start software development?
With a free initial consultation and a joint workshop to clarify requirements and goals.
How long does it take to develop a platform?
Depending on the scope: An MVP is often possible in 8-12 weeks, complex platforms require several months.
What are the costs of development?
Transparent billing: based on effort (with cap) or fixed price modules. Before the project starts, you will receive a reliable cost estimate.
Which technologies do you recommend?
Depending on requirements. Commonly used: Spring Boot, Vue.js or Angular, Flutter as well as Kubernetes and Docker.
Do you also develop customer portals?
Yes. We develop customer portals for self-service, documents, tickets, orders or contract management. Roles, rights, SSO, integrations and clear KPIs are important.
Do you continue to support the platform after its launch?
Yes. We take care of operation, monitoring, security updates and further development within the framework of clear SLAs.
Do you also take over existing projects?
Yes. We stabilize, modernize and continue to deliver: including audit, onboarding and knowledge transfer.
What is a customer portal?
A customer portal is a web-based or app-based platform through which customers can independently access information, documents, orders, tickets or service functions without having to contact an employee each time. Typical content: contracts, invoices, maintenance records, spare parts orders, status overviews. Customer portals reduce support effort and improve customer loyalty.
How much does it cost to develop a customer portal?
Costs depend on scope, integrations (ERP, CRM, SAP) and user roles. A simple self-service portal starts at around 20,000 to 40,000 euros. Complex B2B portals with multiple roles, SSO, API connections and a mobile app typically cost between 60,000 and 150,000 euros. In the initial consultation you will receive a realistic assessment.
How much does it cost to have a web app developed?
A simple web app without complex data logic starts at around 15,000 to 30,000 euros. Structured web apps with backend, roles, interfaces and admin area typically cost between 40,000 and 100,000 euros. Scalable SaaS platforms beyond that. The development time for an MVP is 8 to 14 weeks.
How long does it take to develop a B2B portal?
A structured MVP of a B2B portal is possible in 10 to 16 weeks if requirements and interfaces are clear. More complex portals with multiple roles, SSO, ERP connection and mobile app require 4 to 9 months. Scope clarity is crucial at the beginning.
What is individual software and when is it worthwhile?
Individual software is a tailor-made software solution that is developed specifically for the needs of a company, in contrast to standard software such as SAP or Salesforce. It is worthwhile if: (1) no standard solution maps the specific processes, (2) competitive advantages are to be achieved through unique digital processes, or (3) existing systems that do not support standard solutions need to be integrated.
What is software modernization?
Software modernization refers to the gradual or complete overhaul of existing software systems that are technically outdated, difficult to maintain or not scalable. Typical measures: refactoring the code base, migrating to modern frameworks, replacing outdated monoliths with microservices, improving CI/CD processes and security. The goal is a system that can be further developed productively again.
Individual software or standard software for a customer portal?
Standard software (e.g. Salesforce, ServiceNow, HubSpot) is often quicker to implement and cheaper for generic requirements. Individual software is worthwhile if: specific processes or integrations overwhelm standard solutions, vendor lock-in should be avoided, or data must be stored on your own servers (compliance, GDPR). In the initial consultation you will honestly assess whether your own solution makes sense.
How much does it cost to develop an individual platform for a medium-sized company?
For medium-sized companies, an initial structured platform (web app + backend + admin) typically costs between 50,000 and 120,000 euros, depending on the scope of integrations, user roles and scaling requirements. There are also ongoing operating costs. We give a realistic assessment in the initial consultation, without fantasy prices and without unrealistic fixed prices.
Who develops customized digital platforms for companies?
Customized platforms are created by agencies with their own backend team, cloud experience and proven B2B projects in operation, not by design studios that outsource development. CodeGuides GmbH develops individual web apps, portals and platforms completely in-house in Germany: scalable backends, clear API architectures, cloud operation on German servers.
