# AR DATEV Duo export and product GL accounts

Export receivables to DATEV Duo with product and line GL accounts.

Export **issued** receivable invoices to **DATEV Duo** (Ausgangsrechnungen / receivables ledger): set **GL accounts** on products and lines, **Debitor** (Personenkonto) on customers, and run **Export to accounting** from the receivable invoice workflow.

**Who this is for:** German AR teams on DATEV Duo who need outbound invoice PDFs and booking data in the receivables section, not only payables EXTF.

## 1. Product and line GL accounts

1. **Receivables → Products**: set **GL account** on each product (revenue / Sachkonto as required by your DATEV chart).
2. On a receivable **draft**, line items show a **GL** column prefilled from the product.
3. You may edit line GL on draft; after **issue**, GL remains editable until DATEV Duo export **completes** for that invoice.

## 2. Customer debitor account

On **Receivables → Customers**, maintain **Debitor account** (Personenkonto) for each billing customer.

Export eligibility checks debitor + line GL before sending to DATEV Duo.

## 3. Workflow: Export to accounting

1. **Settings → Workflow Configuration** → entity **Receivable invoice**.
2. Add **Export to accounting** on the path after issue (often after **Mark as issued** / email step).
3. Target **DATEV Duo** only when Duo is the connected accounting export for receivables (`section: receivables` / folder **Ausgangsrechnungen**).

Eligibility typically requires:

- Status **Issued** or **Paid**
- Stored invoice **PDF**
- Customer **Debitor** and each line **GL**

## 4. Export outcome

When the workflow step runs:

- Cortena uploads or registers the receivable per DATEV Duo receivables integration rules.
- Success moves display status toward **Synced** (or your configured exported state).
- Blocked export shows reasons (missing debitor, missing GL, blocked month if applicable).

## Tips and limitations

- DATEV **Rechnungswesen** payables EXTF is separate. See [DATEV Rechnungswesen](https://help.cortena.ai/guides/integrations/datev-rechnungswesen).
- Duo connection is under **Settings → Integrations**. See [DATEV Unternehmen online](https://help.cortena.ai/guides/integrations/datev-unternehmen-online).
- Twinfield / Exact receivable export use different drivers, not this article.
