Once the registration is complete, your client will receive a notification on their home screen within the Accountable app. The notification will inform them that the accountant has successfully registered them for Peppol through Accountable. The client will have the option to either confirm the registration or unregister themselves if they prefer.

⚠️ Important reminder!

Please do not forget to attach your documents to the email. Without the documents, we won’t be able to approve the request. In some cases, we may ask for a short video call to verify your identity.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful. Combined with the AI I never feel alone with Accountable.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
