Complex solution sought for both a general contractor and furniture manufacturer

As a management consultant, I am looking for a complex solution for one of my clients that covers both general contracting and furniture production. This means that my client is a general contractor in the construction and furniture industry. For example, when it comes to coordinating and supervising the equipment and interior design of a building. Technical building equipment and, for example, interior furnishings such as furniture, carpets, and lamps are used in the construction of buildings. The client sometimes manufactures the furniture itself or has it manufactured.

The software should meet the following requirements:

General contractor:

• Calculation
• Quotations

• Order history

• Resource planning
• Awarding
• Tendering
• Partial invoicing

• E-forms
• E-signatures
• Messenger
• BIM
• Construction log
• Construction wages
• Certain construction services
• Customer communication
• Tasks
• Documentation
• Price inquiries and orders to your manufacturers and wholesalers
• DATANORM
• Product catalogs in the cloud for easy calculation

Furniture construction:

The preference is for an on-premises version. However, use in a cloud may be possible.

Approximately 120 software workstations are planned. Work will be carried out in an MS Windows system landscape.
