Management consultant seeks cloud-based industry software for start-up in pipeline civil engineering

I work as a management consultant and am looking for cloud-based industry software for a company that wants to establish itself in the German market in the field of underground pipeline construction.

The software must meet the following requirements:

• (Internal) quote calculation
• Digital (construction) order management
• Documentation
• Measurement
• Billing
• Accounting system interface (initially to an accounting service, later to SAP within the group)
• Cloud-based

Three to four software workstations will be required at the outset.
