# DATEV – Overview
> Import open items from DATEV and upload paywise statements to DATEV Unternehmen online
# paywise for DATEV
The DATEV integration is paywise's largest bookkeeping connector. It consists of
**two independent features** that you set up, pause and use separately:
Pull open items from your DATEV bookkeeping into paywise as claims — manually or
on a schedule with rules.
Upload your paywise statements and advance invoices automatically as documents to
DATEV Unternehmen online.
You can use both features together — or only one.
## The two features compared
| | Import open items | Belege online |
| ------------------- | ---------------------------------------------------- | ------------------------------------------------------ |
| Direction | DATEV → paywise | paywise → DATEV |
| What moves | Open items become claims | Statements and advance invoices as documents |
| What you authorise | **DATEV Connect** (access to your DATEV environment) | **DATEV authorisation** for the document image service |
| Additionally needed | A linked DATEV client, terms of use | A client data set and a document type |
| Runs automatically | Optionally, on a schedule with rules | Yes, for every new statement |
The terms of use of the DATEV integration cover the **import**. Uploading to Belege
online relies on the DATEV authorisation itself.
## Before you start
* A paywise account and a company to set the connection up for.
* Your **DATEV client** — either by signing in with your DATEV account, or as a
**Beraternummer** (consultant number) and **Mandantennummer** (client number).
* For the import: access to your DATEV environment via **DATEV Connect**. Setting
that up requires a DATEV SmartCard or an identity document, and normally your IT
partner.
The DATEV import and a classic bookkeeping integration — such as Lexware Office,
sevdesk or WISO MeinBüro — cannot be active as import sources at the same time.
paywise refuses the DATEV setup in that case. Disconnect the existing bookkeeping
integration first.
**Exception:** easyVerein is a separate collection-import source and can remain
connected alongside the DATEV import.
## What paywise does with DATEV
paywise **reads** your open items, master data and documents from DATEV, and
**writes only** the paywise documents you released — statements and advance invoices
— as documents to DATEV Unternehmen online. Your bookkeeping is never modified,
settled or reversed by paywise.
## Next
Link the client, set up DATEV Connect, authorise the connection.
Connection expired, document type gone, import creating too many claims.
