Invoice clients for iOS app development, SwiftUI interfaces, and App Store launches. Professional invoices from Tidybill.
An iOS developer invoice covers work building native applications for Apple's iPhone and iPad platforms using Swift or Objective-C. iOS developers handle everything from initial app architecture and SwiftUI or UIKit interface development to backend integration, local data storage, push notifications, in-app purchases, and App Store submission. Because iOS development requires an Apple Developer account and involves a review process by Apple, invoices often include app store fees and submission support as line items. Native iOS development commands a premium over cross-platform alternatives due to platform-specific knowledge requirements. Invoices are typically structured around milestones or sprints, with clear descriptions of what features or screens were completed in each billing period. Post-launch maintenance covering OS updates, bug fixes, and new iOS feature adoption is a common ongoing revenue stream.
| Service | Typical Rate | Unit |
|---|---|---|
| iOS app development (hourly) | 85 | hour |
| iOS MVP build | 12000 | project |
| SwiftUI feature development | 900 | feature |
| App Store submission and setup | 350 | project |
| In-app purchase integration | 600 | project |
| Monthly iOS maintenance retainer | 500 | month |
Invoice in milestones aligned to the development roadmap. A typical structure is: 35% deposit, 30% at core features complete, 20% at testing and QA complete, 15% at App Store approval. For maintenance retainers, invoice monthly with a summary of OS updates applied, bugs fixed, and any new features delivered. Reference the app name and milestone clearly on every invoice. Pass through the Apple Developer account fee annually as a reimbursable expense if you manage the account on the client's behalf.
