This FAQ provides a clear, client-focused overview of the key implications of the Contract for Development on Software Projects.
Ownership & IP
Ownership depends on Section 8. With Copyright Transfer, ownership passes to you only after full payment for the task.
No. Using or redistributing unpaid or unaccepted work is a copyright violation (Section 8.4.1).
The Developer keeps ownership of Background Technology but grants you a perpetual, royalty-free license (Section 9.2).
Quality & Warranty
You receive a 90-day warranty. Defects must be fixed at no cost or refunded (Section 6.14).
You have 90 days. After that, work is deemed accepted automatically (Section 6.12).
You must test the software in your own environment and production system (Section 6.10).
Deadlines & Priority
Only with the Expert Package. Missed deadlines allow a 20% fee reduction (Section 13.3).
Priorities are proposed by the Developer but must be mutually agreed upon (Section 6.4).
Depends on your package. Expert includes ≥8 hours/week with no maximum (Section 13).
Payments & Legal
Prepaid and subscriptions require upfront payment. Postpaid is only available after €500 prior payments (Section 14).
Late payments incur interest at 9% above the ECB base rate after 5 days (Section 14).
Either party may terminate at any time. Swiss law applies, with binding arbitration in Zurich (Sections 4 & 15).
General
Yes, of course. We can adapt the contract or create an addendum to it, so that both you and me are fully satisfied.
Yes. You can change the minimum guaranteed hours at any time, even down to 0 hours, by contacting the Developer (Section 13 Intro).
After payment yes. This is a critical distinction in Section 8.4.1 (Clarification for Cumulative Workflows). Even if you own the "base" software, you do not own any subsequent modifications or extensions until those specific changes are paid for and accepted. You cannot use the new updates until payment is cleared, even though they sit on top of code you already own.

Unlike the traditional software development approach, where requirements are defined up front, and you only see the finished product months later, I follow a more flexible, collaborative process. We have a weekly call to review and test the software together, so you can give direct feedback as the product evolves. This way, you’re not locked into early assumptions; instead, the software grows with your needs and I get a deeper understanding of your vision. In fact, the projects where I’ve applied this method have consistently led to the highest client satisfaction and best results. The details of how often and long these meetings are, is fully up to you and the complexity of your project.
I provide professional custom software development services that help businesses streamline operations, improve productivity, and accelerate digital transformation. From startups and small businesses to enterprise organizations, I design, develop, modernize, and maintain high-performance software solutions tailored to your exact business requirements. Whether you need a custom ERP system, CRM software, business management platform, enterprise application, workflow automation, or scalable cloud solution, I deliver secure, future-proof technology built for long-term success.
My custom ERP and CRM development services enable businesses to manage customers, employees, inventory, finances, projects, and internal operations from a single centralized platform. I build fully customized ERP systems, CRM software, admin panels, business dashboards, customer portals, employee management systems, inventory management software, order management platforms, and workflow solutions that are designed around your unique processes instead of forcing your business to adapt to generic software. Every application is optimized for performance, scalability, security, and ease of use.
If your company relies on aging software, my legacy application modernization services help upgrade outdated systems without disrupting daily operations. I migrate legacy applications to modern technologies, improve application performance, strengthen cybersecurity, refactor legacy code, optimize databases, modernize user interfaces, and ensure long-term maintainability. Whether you need software migration, database migration, cloud migration, application reengineering, or complete digital transformation, I make legacy systems faster, more secure, and easier to maintain.
My API development and third-party integration services allow businesses to connect all their essential tools into one seamless ecosystem. I integrate payment gateways such as Stripe and PayPal, communication platforms including Twilio, mapping services like Google Maps, cloud storage solutions such as Dropbox, CRM platforms, ERP systems, accounting software, REST APIs, GraphQL APIs, Webhooks, authentication providers, email services, analytics platforms, and virtually any third-party application. These integrations eliminate manual work, synchronize data automatically, and improve overall business efficiency.
I also specialize in cross-platform application development, creating powerful software that runs consistently across Windows, macOS, Linux, Android, and iOS from a unified development strategy. Whether you require desktop applications, mobile apps, enterprise software, business tools, SaaS platforms, or internal management systems, I build responsive, high-performance applications that provide a consistent user experience across every device while reducing development costs and simplifying maintenance.
My business process automation and workflow optimization services help organizations eliminate repetitive manual tasks through intelligent automation. By automating approvals, document processing, customer onboarding, notifications, reporting, data synchronization, scheduling, inventory updates, and other repetitive workflows, businesses save valuable time, reduce human error, improve operational efficiency, and scale their operations more effectively. I develop custom automation solutions that integrate seamlessly with your existing infrastructure and support long-term business growth.
In addition to software development, I provide technical consulting and software architecture advisory services for organizations making critical technology decisions. Our consulting covers software architecture, cloud architecture, system design, scalability planning, performance optimization, DevOps strategy, project recovery, technical audits, code reviews, software quality assurance, security assessments, development team scaling, technical hiring, CTO consulting, digital transformation strategy, and long-term technology roadmaps. I help businesses reduce technical debt, avoid costly mistakes, improve software quality, and build technology platforms capable of supporting future growth.
By combining custom software engineering, enterprise application development, cloud solutions, API integrations, automation, modernization, and strategic technology consulting, I deliver reliable, scalable, and secure digital solutions that improve efficiency, reduce operational costs, and give businesses a competitive advantage in today's rapidly evolving digital landscape.
