Regulatory Considerations for Software Development in Ireland
Software projects may need to account for Irish and EU requirements depending on their purpose, users, and data. Citrusbug considers relevant technical and security requirements during discovery and translates them into practical design and development decisions.
GDPR and Data Protection
Privacy considerations include access controls, data retention, encryption, and processes for handling data subject requests, based on the product’s requirements.
Cybersecurity Requirements
Applicable cybersecurity rules influence system access, audit logging, incident handling, and security testing. Requirements depend on the organization and the software’s role.
Accessibility Requirements
Where accessibility rules apply, interface design and testing account for relevant accessibility standards to help users navigate and operate digital services.
EU AI Act
AI-powered features may require transparency measures, risk assessment, or human oversight depending on their use and classification. These considerations are reviewed during planning and development.

What Drives Custom Software Development Cost
Custom software development costs depend on the features, integrations, security requirements, and platforms involved. Understanding these factors early helps you prioritize requirements and plan a realistic budget.
Feature Scope and User Roles
Each user role adds workflows, screens, permissions, and test cases. A two-role internal tool generally costs less than a marketplace with separate buyer, seller, and administrator experiences because it requires fewer features and interactions.
Integrations and Architecture
Integrating systems such as Sage, Salesforce, or banking APIs increases development and testing effort. Costs rise when APIs are poorly documented, data needs extensive transformation, or multiple systems must stay synchronized.
Security and Regulatory Requirements
Encryption, audit trails, access controls, and resilience testing add implementation and verification work. Products handling sensitive data or subject to specific regulatory obligations may need additional safeguards and documentation.
Platforms and Ongoing Support
Supporting web, iOS, and Android increases the effort required for development, testing, and maintenance across platforms. Hosting, monitoring, updates, and support arrangements also contribute to long-term ownership costs.
How Much Does It Cost to Develop Custom Software in Ireland?
Focused builds such as an MVP or internal tool typically start around $25,000, while multi-platform enterprise systems can exceed $150,000. Share your scope for a written estimate.

Read Article →FAQs about Software Development Company in Ireland
How do I choose a software development company in Ireland?
Check delivery evidence first, such as case studies and verified reviews. Then ask how the partner handles discovery, GDPR, code ownership, and post-launch support. Clear written answers on each tell you more than a sales deck.
How much does custom software development cost in Ireland?
Focused builds typically start around $25,000, and enterprise platforms can exceed $150,000. User roles, integrations, platforms, and regulatory scope drive the figure, and discovery produces a written estimate before you commit.
How long does a custom software project take?
An MVP or internal tool often takes three to five months, while larger platforms run in phases over six to twelve months. Discovery fixes the timeline for each phase before development begins.
Can you build GDPR-compliant software for an Irish company?
Yes. We incorporate privacy-by-design principles, appropriate access controls, data retention policies, and suitable hosting arrangements into software development. Where Citrusbug processes personal data on your behalf, we address the required data processing terms, while your organization remains responsible for its obligations as controller where applicable.
Does NIS2 apply to my business software?
It depends on your sector and size. Medium and large entities in sectors such as energy, transport, health, digital infrastructure, and manufacturing are typically in scope. Discovery flags likely obligations for your legal adviser to confirm.
Who owns the source code and IP?
You do. Full source code and intellectual property transfer to you at delivery, and an NDA covers the engagement from the start. Repositories can sit in your own GitHub, GitLab, or Azure DevOps organization.
What do you need from us to start?
We need a short brief, access to people who know the current workflow, and a decision-maker for sign-offs. Existing documents, spreadsheets, or system access help discovery move faster.
