Professional Software Development in Perth, Western Australia

Custom software development costs in Perth typically range from $30,000 for small business applications with basic functionality to $80,000 to $200,000 for mid-sized custom systems with integrations and complex workflows, and $300,000 to $1,000,000+ for enterprise software platforms with advanced features and high scalability. Small business applications with straightforward workflows, simple databases, and basic user interfaces start around $30,000 to $60,000 and take 10 to 14 weeks. Mid-sized custom software with moderate complexity, third-party API integrations, custom reporting, and multi-user access ranges from $80,000 to $200,000 over 16-24 weeks. Enterprise software platforms with extensive functionality, multiple system integrations, complex business logic, advanced security, and high scalability typically exceed $300,000 and require 26 to 52+ weeks. At Dapth, we provide transparent, fixed-price quotes after a thorough discovery phase where we document detailed requirements, map user journeys, identify technical dependencies, and assess integration complexity. Unlike agencies that provide vague estimates, we break down costs by development sprint, feature set, and integration complexity so you understand exactly what you're paying for and can make informed decisions about scope priorities and phasing

Most custom software projects in Perth take 12 to 24 weeks from discovery to launch, with timelines varying significantly based on complexity, integration requirements, feature scope, and client feedback cycles. Simple business applications with straightforward workflows and minimal integrations are completed in 10 to 14 weeks. Mid-sized custom software with moderate complexity, several third-party integrations, custom reporting, and multi-user functionality requires 16 to 24 weeks. Enterprise software platforms with extensive functionality, multiple system integrations, complex business logic, high scalability requirements, and comprehensive testing typically require 26 to 52+ weeks. The timeline includes discovery and requirements analysis (2 to 4 weeks), design and prototyping (2 to 4 weeks), agile development sprints (8 to 40+ weeks), testing and quality assurance (2 to 4 weeks), and deployment and launch (1 to 2 weeks). Dapth uses an agile development methodology with 2-week sprints, allowing you to see working software early in the process and provide feedback throughout rather than waiting months for a final delivery. This iterative approach reduces risk, ensures the software meets your needs, and allows for adjustments as requirements evolve

Dapth's Perth software development team specializes in modern, enterprise-grade technologies including .NET 8 and C# for robust, scalable backend systems and enterprise applications, Python 3.12 for data processing, machine learning, API development, and automation scripts, React 18 and TypeScript for modern, responsive web interfaces with excellent user experience, Node.js for JavaScript-based backend services and real-time applications, Microsoft Azure for cloud hosting, serverless functions, managed databases, and DevOps pipelines, PostgreSQL and SQL Server for relational databases with strong consistency and ACID compliance, MongoDB for document-based data storage and flexible schemas, Docker and Kubernetes for containerization, orchestration, and scalable deployments, and Redis for caching, session management, and real-time data. We select technologies based on your specific requirements, existing infrastructure, team capabilities, long-term maintainability, and scalability needs rather than forcing every project into the same technology stack. For enterprises with existing Microsoft infrastructure, we leverage .NET and Azure for seamless integration. For startups prioritising rapid development, we might recommend Python and React. For data-intensive applications, we use Python with specialised libraries for data processing and analysis.

Custom software is built specifically for your business requirements, workflows, and processes, while off-the-shelf software is generic software designed to serve many different businesses with similar needs. Custom software provides an exact fit to your unique requirements, a competitive advantage through proprietary functionality, flexibility to change as your business evolves, integration with your existing systems and data, no ongoing license fees (you own the software), and no unnecessary features or complexity. Off-the-shelf software provides lower upfront cost, faster initial implementation, proven functionality with existing user base, regular updates and support from vendor, and no development risk. Custom software is ideal for businesses with unique processes that provide a competitive advantage, organisations requiring specific integrations not supported by off-the-shelf software, companies with workflows that don't fit standard software patterns, businesses requiring complete control and data ownership, and organisations where software is core to business operations. Off-the-shelf software is ideal for standardised business processes (accounting, payroll, email), businesses with limited budget for custom development, companies needing quick implementation, and organisations comfortable adapting processes to fit software constraints.

Yes, Dapth provides comprehensive ongoing support and maintenance for all custom software we develop in Perth including bug fixes and technical support with 24-hour response time for urgent issues, security updates and patches for frameworks, libraries, and dependencies, performance monitoring and optimization to maintain fast response times, feature enhancements and new functionality as your business evolves, infrastructure management and scaling for cloud-hosted applications, database maintenance and optimization, backup and disaster recovery management with regular testing, monthly performance and usage reports with recommendations, and strategic consultation for software evolution and roadmap planning. We offer flexible support arrangements from pay-as-you-go hourly rates ($200/hour) to monthly retainer packages starting from $1,000/month. Our support retainers typically include 5-20 hours of monthly support time, priority response for urgent issues, proactive monitoring and alerting, monthly performance reports, quarterly strategic reviews, and direct access to your dedicated development team. Many Dapth clients maintain ongoing relationships spanning 5+ years, with software continuously evolving to meet changing business needs, incorporate new technologies, integrate with new systems, and improve based on user feedback and analytics data. Unlike agencies that "build and abandon" after launch, we view software delivery as the beginning of a long-term partnership focused on continuous improvement and business value.

Yes, Dapth specialises in software integration, connecting custom software with existing systems to enable seamless data flow and process automation. Our Perth software developers have extensive experience integrating with CRM platforms (Salesforce, HubSpot, Microsoft Dynamics 365, Zoho), ERP systems (SAP, Oracle, Microsoft Dynamics, Odoo, MYOB), accounting software (Xero, MYOB, QuickBooks, Sage), e-commerce platforms (Shopify, WooCommerce, Magento, BigCommerce), marketing automation (Marketo, Pardot, HubSpot, Mailchimp), payment gateways (Stripe, PayPal, eWAY, SecurePay), document management (SharePoint, M-Files, DocuSign), and custom or legacy systems through API development or database integration. Our integration approach includes thorough discovery to understand data flows and business processes, API assessment to evaluate integration options and limitations, authentication and security implementation (OAuth 2.0, API keys, JWT), error handling and retry logic for reliability, data transformation and validation to ensure data quality, real-time or batch synchronization based on requirements, comprehensive logging and monitoring for troubleshooting, and detailed documentation for maintenance. For legacy systems without modern APIs, we can develop API wrappers or use database-level integration where appropriate. Integration complexity typically adds $15,000 to $80,000 to project costs, depending on the number of systems, data complexity, and API quality.

Agile software development is an iterative approach that delivers working software in short cycles (sprints) rather than waiting months for a final delivery, allowing for regular feedback and adaptation throughout the project. Dapth uses agile methodology because it reduces risk by identifying issues early when they're easier and cheaper to fix, ensures the software meets your needs through regular demos and feedback, allows for changing requirements as you learn and your business evolves, delivers value incrementally so you can start using features before the entire project is complete, improves transparency through regular communication and visible progress, and increases quality through continuous testing and refinement. Our agile process includes 2-week sprints with defined goals and deliverables, sprint planning sessions to prioritize work and estimate effort, daily stand-up meetings for team coordination (you're welcome to join), development and testing of prioritized features, sprint demos where you see working software and provide feedback, sprint retrospectives to continuously improve our process, and regular backlog refinement to adjust priorities based on learning. Unlike waterfall development, where you don't see working software until the end, agile lets you see and use features as they're completed, provide feedback that shapes subsequent development, and adjust priorities based on what you learn. This approach is particularly valuable for complex projects where requirements may evolve or for businesses that need to respond quickly to market changes.

Dapth implements comprehensive security practices throughout the software development lifecycle including secure coding practices following OWASP guidelines, authentication and authorization using industry-standard protocols (OAuth 2.0, JWT, multi-factor authentication), data encryption in transit (TLS/SSL) and at rest (AES-256), input validation and sanitization to prevent injection attacks, protection against common vulnerabilities (SQL injection, cross-site scripting, CSRF, remote code execution), regular security updates for frameworks, libraries, and dependencies, automated security scanning during development and deployment, penetration testing and vulnerability assessment before launch, security logging and monitoring for threat detection, and compliance with relevant security standards (Australian Government ISM, ISO 27001, PCI DSS where applicable). For enterprise and government clients, we implement additional security measures including role-based access control with principle of least privilege, audit trails for all sensitive operations, data classification and handling procedures, security incident response procedures, regular security audits by independent third parties, disaster recovery and business continuity planning, and compliance with industry-specific regulations (HIPAA for healthcare, Privacy Act for personal information). All Dapth developers receive regular security training and follow secure development practices. We use Azure cloud services, which provide enterprise-grade security, compliance certifications, and data sovereignty with Australian data centres.

Yes, Dapth specialises in legacy software modernisation and replacement for Perth businesses running outdated software built on end-of-life technologies. Our legacy modernization approach includes comprehensive assessment of existing software (functionality, data structures, integrations, pain points), modernization strategy development (re-platform, re-architect, or rebuild), risk assessment and mitigation planning, data migration strategy with validation procedures, phased migration approach to minimize business disruption, parallel running period for validation and confidence, user training and change management support, and post-migration support and optimization. We have experience modernising legacy systems, including Visual Basic 6 applications to .NET 8, classic ASP websites to modern web applications, .NET Framework applications to .NET 8 and cloud-native architecture, Access databases to SQL Server or PostgreSQL, on-premise applications to cloud-based solutions, and monolithic applications to microservices architecture. Legacy modernisation typically costs 60-80% of building new software from scratch but preserves proven business logic, maintains data continuity, and reduces risk compared to complete replacement. For Perth businesses with software built 10+ years ago, modernisation addresses security vulnerabilities, improves performance, enables mobile access, facilitates integration with modern systems, and reduces maintenance costs while preserving institutional knowledge embedded in the existing software.

Yes, Dapth develops mobile applications for iOS and Android as standalone apps or as mobile interfaces for custom software systems. Our Perth mobile development team builds native apps (Swift for iOS, Kotlin for Android), cross-platform apps (React Native, Flutter), or progressive web apps (PWA), depending on your requirements, budget, target audience, and performance needs. Mobile applications are often developed alongside custom software to provide field access for employees, customer-facing experiences for clients, offline functionality for remote workers, or modern interfaces for legacy systems. Mobile development typically adds $40,000-$150,000 to project costs depending on complexity, platform requirements (iOS only, Android only, or both), offline functionality needs, and integration requirements. For businesses requiring mobile access to custom software, we design the backend API to support both web and mobile interfaces, implement authentication and security appropriate for mobile devices, develop offline functionality with data synchronisation, optimise performance for mobile networks, and handle app store submission and management. Mobile applications are particularly valuable for field service organisations, sales teams, healthcare providers, education institutions, and businesses with remote workers who need access to systems while away from the office..

Software requirements often evolve after launch as you use the system, receive user feedback, and identify new opportunities. Dapth provides flexible options for post-launch changes, including minor bug fixes and adjustments during the 30-day warranty period at no charge, feature enhancements and new functionality through additional development sprints, ongoing development retainers for continuous improvement and evolution, pay-as-you-go hourly rates for occasional changes and support, and annual enhancement projects for major new features or modules. For clients on monthly support retainers, we allocate a portion of the retainer hours to small enhancements and improvements based on your priorities. For larger enhancements, we conduct a mini discovery phase to document requirements, estimate effort, and provide a fixed-price quote before proceeding. Because we build software using modern, maintainable code with comprehensive documentation, making changes is straightforward and cost-effective. We maintain the source code in version control, document architectural decisions, write automated tests to prevent regressions, and ensure knowledge is shared across the team so you're not dependent on a single developer. Many Dapth clients continue working with us for years after initial launch, continuously improving and expanding their software as their business grows and evolves.

Dapth uses structured project management and transparent communication to ensure software projects stay on track, on budget, and aligned with your expectations. Our project management approach includes dedicated project manager as your primary point of contact, bi-weekly sprint planning and review meetings (in-person at our Perth office or via video call), daily stand-up meetings for team coordination (you're welcome to join), Azure DevOps for task tracking, sprint progress, and backlog management, Slack or Microsoft Teams for day-to-day communication and quick questions, bi-weekly sprint demos where you see working software and provide feedback, monthly executive summaries for stakeholders and leadership, and transparent reporting on progress, risks, and budget. You'll have real-time visibility into project progress through Azure DevOps, where you can see completed work, work in progress, and upcoming priorities. Our project managers proactively identify and communicate risks, manage scope changes through a formal change request process, track budget and timeline against original estimates, and coordinate with your team for requirements clarification, testing, and feedback. For Perth-based clients, we prefer face-to-face meetings for discovery, sprint demos, and key decision points, as in-person collaboration leads to better understanding and stronger relationships. For clients outside Perth, we use video conferencing and screen sharing to maintain the same level of engagement and collaboration.
