  • Choosing the right partner is essential for the growth of your company. In A-Cube we have found professionalism, competence, and passion as well as a reliable and robust service. All-round brilliant experience!

    Andrea Soracchi
    CEO @ Multicerta
  • After several months of using your service I can say that we are really satisfied.
    The integration has allowed us to significantly lower the costs and time required for invoicing management.
    Our company is English, and initially our system did not provide for the sending and receiving of e-invoices. We were forced to use an external service, with related licensing costs.
    A-Cube proved to be very versatile and the integration made without problems.
    In the testing phase, when we found some problems, we always received assistance quickly.
    Without a doubt A-cube has become an integral part of our workflow!
    Mitsuharu Hirose
    Manager @ MediMatch Dental

Integrating it was quick and easy, this allowed us to optimize the development times of our platform in a not indifferent way. Furthermore, the preparation and support of their customer care is what really makes the difference. Anyone who needs services of this type I am sure will find the definitive solution in Acube.

  • The system is fully functional and fully satisfies the customer's needs.
    The added value is certainly exemplary assistance, with very short response times, and also the precision and accuracy in the answers given to any question.
    Paolo Capaldo
    Owner @ Res Binaria
  • We have been working with A-Cube since before e-invoicing became mandatory and our collaboration experience has always been positive.

    The service has always proved to be reliable and performing and in the very rare cases of anomalies the support has always been prompt and decisive.

    Even in the case of operational and / or technical implementation clarifications, we have always found full availability in the ways and times that lead to a quick resolution.

    The documentation for us has always been exhaustive and easy to consult.
    Mario Colabianchi
    Founder & CEO @ Digital
  • Acube was very efficient in both the commercial and technical phase. Well done documentation for fast integration and they are always available for any questions.
    Filippo Primieri
    Co-founder @ FidoCommercialista.it
  • I was wrong not to rely on Acube right away. E-invoicing was a novelty and so, compared to choosing a startup, I decided to focus on an already consolidated company. It was a mistake because the problem of a badly designed interface was added to the problem of e-invoicing. Since I terminated that contract to switch to Acube I have never looked back.
    Duccio Armenise
    Founder @ Corsidia.com
  • We have integrated A-Cube's APIs into our customers' software with speed and simplicity. Furthermore, the calculable cost per document allowed us to immediately activate the service for everyone.
    Francesco Benetton
    Progettista analista programmatore
  • For some time we have struggled with the SDI to integrate our software directly with the tax authority to send, receive and store e-invoices, managing with difficulty and with various problems. Until, tired of wasting time and energy, we looked for someone who did just this and could sell us API ready and suitable for cutting-edge developments in order to return to focus on our real business. We found A-Cube and we immediately fell in love with it: not only because their service perfectly covered all our needs and had a fair price, but because, by contacting them, we found honest people, available and attentive to the quality of what they did .. .we had found a partner with whom to work well together! Now after years I am still very satisfied with the choice made.
