„blue office^® is very user-friendly and the easy access made us realize how clearly all data can now be retrieved. We think it's great that we can, for example, copy a created quotation into a new customer's quotation and then adapt it. Manual items can also be entered quickly. As we manage both debtors and creditors with blue office^® payments can be easily processed and posted. Even the monthly payroll postings are quickly exported to FIBU. When preparing the VAT statements for each quarter, we are therefore sure that we haven't forgotten anything. Our trustee comes to our office for the closing. She also finds it easy to handle the bookkeeping. If we have any questions, we are happy to contact the Sieber IT team, who always show us the solutions immediately via remote maintenance. So we are completely satisfied.“
