ADLER Solar GmbH
ADLER Solar GmbH has been using BCS since 2015 as a central platform for order processing, quotation design, documentation, and invoicing. From the first customer contact and project creation through to later billing, sales-related and operational processes are structured in BCS. Quotation creation with BIRT is particularly important: customer data, technical information, item data, profitability calculations, and additional project data are transferred directly from BCS into individually designed quotation documents.
