„The presentation of blue office^® is very friendly. After in-depth training with detailed documentation, we found our way around quickly and easily. We appreciate the prompt support service via remote maintenance provided by the Sieber IT team. We enjoy using the simple linking of quotations, orders, A-account invoices and final invoices. We find it practical that the incoming invoices can be retrieved when they are due and that the DTA file can be created and posted at the click of a button. Creating the VAT statement with the same system also ensures that all postings are included. Financial accounting gives us an insight into the business processes at all times.“
