I want to start my own business and am looking for a complete or industry-specific solution for my electrical trade business, which is currently in the process of being established.

The software should meet the following requirements:

• Quotation creation
• Orders

• (Project) time tracking, e.g., as an app (for Android) would be good

• Optional interface to a standard or format
• Optional connection to wholesalers (material catalogs)
• Local or web-based
• Purchase or rental solution

One software workstation is planned. Work will be carried out using an MS Windows system.
