Project description:
"I am building a mobile expense-capture solution and need the complete app created for both iOS and Android. Each client company receives a private invitation link; once they sign up, they land in their own sealed environment so no data ever crosses company borders.

Core flow
• Employee opens the app, snaps a receipt photo, enters amount and VAT, then uploads.
• Employer views the image and metadata in real time and can approve or decline with one tap.

All the data MUST be stored and can never be deleted. The data also must be sent to us the owner of the app so we can store it.

Must-have features
1. Role-based access: admin (employer) and user (employee) only.
2. Direct export of all stored data to Excel and CSV.
3. Native integrations with both Visma and Fortnox so approved purchases can be pushed straight into Swedish bookkeeping workflows.
4. Elastic architecture that comfortably serves several hundred separate company accounts today and can scale far beyond without lag.

High-level deliverables
• Cross-platform mobile app (iOS + Android).
• Secure multi-tenant backend with invitation-only company onboarding.
• Admin dashboard for approval/decline and data export.
• Visma & Fortnox integration modules, ready for production use.

Acceptance criteria
– Zero data leakage between tenants verified by penetration test.
– Successful push of test transactions into Visma and Fortnox.
– Export produces clean .xlsx and .csv files matching on-screen totals.
– App handles 1,000 concurrent users in load test without noticeable latency (<200 ms for main actions).

I have made a website prototype that will be sent over to you. That will be exactly how we want it to look and work.

We will keep continus contact during the entire process of building the app.

Code ownership, documentation, and post-launch handoff are expected so I can keep extending the platform after initial release." (client-provided description)
