Toolmaker seeks simple archiving or document management software

We are a tool and mold maker based in southern Germany and are looking for simple archiving and document management software.

The software should meet the following requirements:

• Digitize documents that arrive by mail
• Archive documents (e.g., incoming and outgoing invoices, delivery notes, quotes)
• Easy retrieval of documents (e.g., with codes, keywords, or full-text search)
• Interface between tax advisor and company
• Assignment of rights (read, write)
• On-premises solution
• Windows compatible

Five software workstations with full access and an additional seven with read access are required.

Addendum:

The following functions are also required (added on October 1, 2019):

• Scanned or digitized incoming invoices should be moved or saved to a folder, e.g., “unpaid,” if possible.
• Read invoices (IBAN, amount, name, and invoice number), using OCR if necessary.
• Data should be transferred to a transfer program
• The read data should be automatically transferred to the transfer mask
• Then file the invoice with the payment term or due date
