Nova Mobile App Build Sheet

Nova Mobile App Build Sheet is created for freelance developers who invoice mobile app projects in clear milestone stages. It is a strong fit for iOS, Android, and cross-platform builds where design, development, testing, and release support are billed separately. The spreadsheet format gives you a professional app invoice that is easy for clients to review and simple for you to update as the project progresses.

The template includes line items for planning, UI implementation, API integration, QA testing, store submission, and post-launch fixes. You can apply deposits and milestone payments, which is useful when managing longer app engagements with multiple release points. The mobile app billing layout also supports taxes, currency flexibility, and due dates, making it suitable for international freelancers working with startups, founders, and product teams.

Customize the XLSX file by adding your business details, project name, and milestone values, then duplicate it for each release cycle. The Excel template structure makes calculations fast and reduces manual errors, especially when you need to adjust totals or apply regional tax rules. It is a practical choice for developers who want a clean invoicing workflow that matches the complexity of mobile product delivery while staying easy to manage.
