Invoice clients for mobile app development, app store submissions, and maintenance. Professional invoices from Tidybill.
A mobile developer invoice is a billing document for work building iOS, Android, or cross-platform mobile applications. Mobile developers use native languages such as Swift and Kotlin, or cross-platform frameworks like React Native, Flutter, or Xamarin, to create apps that run on smartphones and tablets. Invoices cover the full development lifecycle including requirements analysis, UI/UX implementation, backend integration, device testing, app store submission, and post-launch maintenance. App store submission fees, developer account costs, and third-party SDK licences are common pass-through expenses. Because mobile development projects often stretch over months and involve multiple platforms, milestone invoicing is the norm. Invoices should clearly identify the platform (iOS, Android, or both), the features delivered in each billing period, and any ongoing support or update work.
| Service | Typical Rate | Unit |
|---|---|---|
| Mobile app development (hourly) | 80 | hour |
| iOS app build (MVP) | 10000 | project |
| Android app build (MVP) | 10000 | project |
| Cross-platform app (React Native/Flutter) | 12000 | project |
| App store submission and setup | 400 | project |
| Monthly maintenance and updates | 600 | month |
Use milestone invoicing for large projects: 30-40% upfront, progress payments at defined milestones (e.g. UI complete, backend integrated, testing complete), and final balance on app store approval. For ongoing maintenance contracts, invoice monthly with a list of updates, bug fixes, and OS compatibility work delivered that month. Always specify which platform each deliverable applies to. If you are building for both iOS and Android, consider separate line items per platform so clients can see the cost breakdown clearly.
