ALTOstratus – tax toolbox

ALTOstratus is a convenient app for tax teams. Its functionalities make daily verification of contractors on the “White List” extremely easy and allow to automate creation of documents that were very time-consuming to prepare.

How does ALTOstratus work?

White List

Just upload a list of VAT IDs and / or account numbers, and ALTOstratus algorithms will check exactly who you are dealing with. You can also upload Elixir-O or MT940 files, and each of these formats will be used by ALTOstratus to query KAS systems and quickly return relevant information to you.

JPK & VAT-UE

White List is not the only functionality of our app – ALTOstratus allows you more: to easily check the correctness of the prepared JPK files, it helps you to efficiently convert the JPK file to VAT-EU declaration and substantively tests JPK_V7M files.

Thanks to feedback from our clients, the list of ALTOstratus functions is constantly growing to support best the work of tax teams!
Each registered user has access to all ALTOstratus functionalities – no limits!
