- **Type:** Task
- **Module:** Sales
- **Menu path:** Satış › Faturalama › Faturalanmamış Teslimatlar (Sales › Billing › Unbilled Deliveries)
- **Screen route:** `/erp/sales/unbilled-shipments`
- **Required permission:** `erp-invoicing-references.create`
- **Prerequisites:**
  - The goods issue for the delivery has been posted.
  - The invoice has been issued outside the system, and you have its number and date.

Installations that issue invoices in an accounting program or the e-Invoice portal use this path. If CoreX issues the
invoice (e-Document enabled), [create an invoice from the delivery](https://erpdocs.corexlogic.com/en/satis/islemler/fatura-olusturma) instead.

## Steps

1. Open the **Satış › Faturalama › Faturalanmamış Teslimatlar** (Sales › Billing › Unbilled Deliveries) screen.
   <!-- action: navigate · target: "/erp/sales/unbilled-shipments" -->
2. Check the deliveries that have been invoiced. For a collective invoice, select all deliveries of the same invoice together.
   <!-- action: choose · target: "Belge No" -->
3. Click **Fatura Referansı Gir** (Enter Invoice Reference).
   <!-- action: click · target: "Fatura Referansı Gir" -->

   1. Select the deliveries to invoice
   2. Invoice deadline — 7 days after delivery
   3. Enter Invoice Reference — trace of an externally issued invoice

4. Enter the **Fatura No** (Invoice No.) and the **Fatura Tarihi** (Invoice Date). **Fatura Tutarı** (Invoice Amount) and **KDV Tutarı** (VAT Amount) are optional; if they are entered, **Para Birimi** (Currency) is required.
   <!-- action: fill · target: "Fatura No" · value: "DMO2026000000187" -->
5. Click **Kaydet** (Save).
   <!-- action: click · target: "Kaydet" -->

   ![Enter Invoice Reference dialog](https://erpdocs.corexlogic.com/en/en/img/screens/satis/fatura-referansi.png)
   1. Invoice number — the same number may cover several deliveries
   2. Invoice date
   3. Amount and VAT — optional, a mismatch does not block
   4. Save — the delivery is marked as invoiced

**Result:** The selected deliveries are marked as invoiced and removed from the **Faturalanmamış Teslimatlar** (Unbilled Deliveries) list. A reference is not an invoice: no tax is calculated and nothing is posted to the customer account — the financial record is kept in the program that issued the invoice.

## What you need to know

- An invoice is expected within **7 days** after the delivery. Deliveries whose **Fatura Son Günü** (Invoice Due Date)
  has passed are shown in the list with a warning; they can be isolated with the **Yalnız 7 günü geçenler** (Only
  those older than 7 days) filter.
- Saving is **not blocked** even if the amount does not match the document's calculation; the source of truth is the
  platform that issued the invoice.
- For an export transaction, the **Gümrük Beyannamesi** (Customs Declaration) number and date are entered together.
