Let’s get started.
Amazon Flex is a logistics program that enables individuals to deliver packages using their vehicles. They set their hours and choose available delivery blocks. The Flex app connects independent contractors with delivery opportunities.
Core purpose: Help Amazon deliver smiles to customers homes while giving people a way to earn extra cash in their spare time.
Unlike other delivery platforms, the Amazon Flex app focuses primarily on scheduled delivery blocks, allowing drivers to schedule work ahead rather than waiting for random gigs.

|---|---|
| User onboarding | Register using a valid driver's license, valid ID, and background check |
| Block scheduling | Drivers can reserve delivery blocks and schedule work ahead |
| Real-time GPS tracking | Optimize routes and track delivery time |
| Push notifications | Alert drivers about same day offers, traffic, or schedule changes |
| Document verification | Upload documents like personal auto insurance and social security number |
| In-app navigation | Integrated maps for route optimization |
| Earnings dashboard | Track actual earnings, tax summary, and deposits to bank account or savings account |

| In-store shopper mode | Allow drivers to be an in store shopper or full service shopper for local stores |
| Layer | Suggested Technology Stack |
|---|---|
| Frontend | React Native or Flutter (cross-platform) |
| Backend | Node.js or Django, REST APIs |
| Database | PostgreSQL for relational data, MongoDB for flexible data |
| Cloud | AWS, GCP, or Azure |

Optimize DB reads for delivery time, schedule, and route planning.
Ensure on-road support through live chat or quick ticketing for driver issues.
Allow operators in major cities to manage multiple apps from the same backend.

| Metric | Value |
|---|---|
| Base Pay | $18/hour |
| Incentives | Surge Pricing, Tips |
| Payout Method | Weekly to bank account |

Apps like Amazon Flex must clearly state how drivers earn, how earnings depend on delivery blocks, and what other factors may apply.
Building an app similar to Amazon Flex means deeply understanding the delivery driving opportunity from both the driver’s and customer’s perspectives. From onboarding independent contractors to letting them deliver groceries, dry cleaning, or food, a robust system must account for everything—from notification preferences to dark mode usability.
With a clean tech stack, intuitive UX, and strong backend infrastructure, you can create apps like Amazon Flex that help users deliver smiles and provide great pay in their spare time.
Key takeaway: A successful flex app makes delivering packages easy, respects privacy, and handles complexity so drivers can deliver packages on time, every time.
