## What this module handles for you.

01

### A journal that cannot be changed

Every posting has a debit and a credit and is chained to the previous ones. An integrity check runs through the chain.

02

### Postings from day-to-day business

XOS posts automatically when a purchase invoice is completed, a delivery note is posted, an invoice is sent or a payment is recorded. Manual postings are also possible.

03

### Chart of accounts SKR03 or SKR04

XOS comes with a lean core set of accounts for both charts of accounts.

04

### Cost centers with budget

Build a hierarchy of cost centers, set an annual budget, and see actuals against the budget.

05

### Recurring postings

Templates for rent, salaries and the like post themselves automatically. You can pause them, reactivate them or trigger them right away.

06

### Reports and DATEV export

XOS calculates the balance sheet, profit and loss, a simplified BWA (business analysis) and the advance VAT return from the journal.

Sample process

### From sending the invoice to the DATEV export.

An example of a month-end close.

The invoice is sent, XOS posts the receivable

The payment is recorded, XOS posts the settlement

Wrong posting? A reversal entry instead of a change

Month end: check the BWA (business analysis) and VAT

Export in DATEV format for the tax advisor

Also in the chat: the ERP Agent reads the journal and reports and can prepare postings. Manual postings are a critical step and need your confirmation.

## Frequently asked questions.

Is there a direct interface to DATEV or Lexware?

For DATEV there is a file export, not a direct interface. To Lexware Office, invoices from the Document Generator can be transferred one by one. The accounting itself runs in XOS.

Can I change a posting afterwards?

No. The journal is deliberately unalterable. You correct it with a reversal posting and post again.

Is the advance VAT return sent to the tax office?

No. XOS calculates it and creates a file in the key figure schema that your tax advisor can import. There is no submission to ELSTER.
