What this module handles for you.

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.

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.

Chart of accounts SKR03 or SKR04

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

Cost centers with budget

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

Recurring postings

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

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.
