Wholesale Business Custom Application Development

I am looking to develop a custom application for a wholesale import and export business, and I would like to request your proposal and technical capabilities for this project.

The system should include the following core features:

Invoice generation for retail clients (shops we distribute goods to)

Tracking of all delivered goods per client, including quantities and total value

Payment status tracking (paid / unpaid / outstanding balances)

Multi-language invoice support (English, Arabic, French, Dutch, and German)

Cross-platform usability (mobile phones, tablets, and laptops) with a user-friendly interface

Digital signature functionality upon delivery confirmation

Ability to attach photos of delivered goods as proof of delivery

Additionally, the system should be reliable, secure, and scalable as the business grows.

Please provide:

Estimated development cost

Timeline for delivery

Technologies you recommend

Examples of similar projects (if available)

I am aiming for a practical and efficient solution that can be used daily by a distribution team.

Looking forward to your response.

Best regards,Abdallah
