Invoice clients for Android app development, Kotlin builds, and Play Store launches. Professional invoices from Tidybill.
An Android developer invoice covers work building native Android applications using Kotlin or Java for smartphones, tablets, and other Android-powered devices. Android development involves designing for a wide range of screen sizes and hardware configurations, which often increases testing time relative to iOS. Invoices typically cover app architecture, Jetpack Compose or XML UI development, backend integration, Google Play submission, and post-launch maintenance. Android developers may also build apps for Android TV, Wear OS, or automotive platforms, which command premium rates due to specialised knowledge. Because Android has a larger global market share, many clients prioritise Android for international markets, making clear communication about target API levels and device support essential on invoices and contracts. Ongoing maintenance for Android fragmentation (supporting older OS versions) is a common additional line item.
| Service | Typical Rate | Unit |
|---|---|---|
| Android app development (hourly) | 80 | hour |
| Android MVP build | 11000 | project |
| Jetpack Compose feature development | 850 | feature |
| Google Play submission and store listing setup | 300 | project |
| Firebase integration (analytics, push, auth) | 500 | project |
| Monthly Android maintenance retainer | 450 | month |
Use milestone invoicing for project work and monthly invoicing for maintenance. Include the target API level and minimum Android version in your project description so clients understand the device coverage. Pass through the Google Play developer account one-time fee ($25 USD) as a reimbursable expense if you set it up on the client's behalf. For fragmentation testing across many devices, document the devices tested and bill the testing hours separately from development.
