“5FSoftware has enabled us to communicate and exchange documents with the customer in a more efficient and targeted manner. This helps me and my teams tremendously. By using 5FSoftware, we have saved time and can focus entirely on transaction advisory and auditing. In concrete terms, this means that we can offer the time we save to our clients as an added value.”

“5F understands the special requirements of auditing and tax consulting, implements them flexibly and thus enables us as LKC to communicate “at an eye to eye level” with our clients. “This applies to everything from posting and preparing annual financial statements to auditing consolidated financial statements on an international scale.”

“We chose 5F Software because this tool provides us with a secure and structured data room for exchanging and collecting data and documents. In addition, it was important for us at this point to have a partner at our side who is constantly developing. Our long-term goal is to have no more paperwork leaving the office and we are looking forward to realizing this with 5F in the future.”

“We are convinced that probably hardly any market provider can offer the variety and flexibility of application possibilities as the StartUp company 5FSoftware GmbH from Regensburg. In any case, the decision to choose this company as a partner was the right one.”

„The innovative platform 5F enables me and my clients to provide an efficient, modern and straight tax consulting that lets them relax at the thought of their fiscal concerns. The unique collectos stand for a safe and time saving information and document exchange and amaze my clients and myself.

“With the client portal of 5FSoftware GmbH, I have a SaaS solution, which enables me to collaborate easily and effectively with my clients.” Keyword client communication 4.0: Efficient exchange of process-relevant documents and communication with clients in secure data rooms. This is possible in a super relaxed way with 5F.
Since the end of 2020, previously time-consuming and inefficient workflows, such as initialising new mandates for new clients, have been made much easier for my team and myself with the help of the client portal and have hence been raised to a new level.

Just some of the most valuable features of 5F from my point of view:

  • Easy onboarding of new clients
  • 5F Sign (digital signature) = integrated digital signature workflow
  • Collecto = structured collection of documents
  • Save structures and request lists as templates (e.g. JA, EStE, etc.)
  • Quickshare = secure sharing of documents with third parties (e.g. auditors)

Besides that I like the possibility of creating an own firm-URL for the clients portal as well as the clear dashboard which always gives me an overview over current projects and due dates.

“A real gamechanger for my tax firm.“
