Mobile Service Station Management App

I'm looking for a skilled developer to create a mobile application for my existing service station business. The app needs to be able to take and process the following data to self-update:

- Opening stock and meter readings
- Purchase prices
- Daily sales volumes
- Site expenditure transactions
- Discounts
- Dip chart readings
- Unit prices
- Closing stock
- Cash flow

The application should be designed specifically for mobile platforms and must be capable of functioning offline as well.

Ideal skills and experience for this project include:
- Proficiency in mobile app development
- Experience in creating data management systems
- Knowledge of financial data processing
- Familiarity with gas station management systems

Please include any relevant experience you have with such projects in your bid.
