How to decide

## **When to choose each model**

### **Choose In-House When**

- Software development is your core, ongoing business activity
- You need a developer available full-time for continuous iteration
- Your product requires deep domain knowledge that takes years to build
- You have a steady pipeline of development work (no idle time)
- Your budget supports full-time salaries and benefits
- You can invest in recruitment, onboarding, and retention

### **Choose an Agency When**

- You have a defined project with a clear scope and timeline
- You need to launch quickly and cannot wait months to hire
- Your project requires diverse expertise (design, mobile, backend, DevOps)
- You want to minimize financial risk with project-based pricing
- You need to scale the team up or down flexibly
- Software development is not your core business competency

Questions

## **Frequently asked questions**

### **Is it cheaper to hire an in-house developer or use an agency?**

It depends on your project timeline. For a single project, an agency is almost always cheaper. For ongoing development spanning multiple years, an in-house developer becomes more cost-effective after 12-18 months, assuming full utilization.

### **How long does it take to hire an in-house developer?**

For senior mobile developers, it can take 60-90 days due to high demand. This includes job posting, screening, technical interviews, offer negotiation, and notice period. An agency can typically start work within 1-2 weeks of contract signing, providing a significant head start when time to market is critical.

### **What happens if my in-house developer leaves?**

Developer turnover is a significant risk. When a key developer leaves, you face knowledge transfer gaps, 42+ days to hire a replacement, and 3-6 months onboarding to full productivity. Agencies mitigate this risk with team-based delivery, replacing members from their bench without disrupting your timeline.

### **Can I combine in-house and agency teams?**

Yes, and this hybrid model is increasingly popular. Common approaches include using an agency for the initial build and an in-house team for maintenance, or using agency staff augmentation to scale your team temporarily for deadlines.

### **How do I ensure quality when working with an agency?**

Look for agencies that provide transparent project management, regular sprint demos, repository access from day one, automated testing, CI/CD pipelines, and clear contracts with defined milestones. Start with a small paid pilot project before committing to a large engagement.

### **Do agencies provide ongoing maintenance after project delivery?**

Most reputable agencies offer post-launch maintenance packages. App369 provides ongoing support including bug fixes, OS compatibility updates, security patches, performance monitoring, and feature enhancements with defined SLAs for response times.
