ใบลดหนี้และการคืนเงิน

A credit/debit note, or credit/debit memo, is a document sent to a customer to inform them that they have been credited/debited a certain amount.

กรณีการใช้งานหลายกรณีอาจนำไปสู่ใบลดหนี้ เช่น:

• ข้อผิดพลาดในใบแจ้งหนี้

• การคืนสินค้าหรือการปฏิเสธการให้บริการ

• สินค้าที่จัดส่งได้รับความเสียหาย

ใบเพิ่มหนี้พบได้ไม่บ่อยนัก แต่มักใช้เพื่อติดตามหนี้ที่ลูกค้าหรือผู้ขายเป็นหนี้ เนื่องจากมีการปรับเปลี่ยนใบแจ้งหนี้ของลูกค้าหรือใบเรียกเก็บเงินของผู้ขายที่ยืนยันแล้ว

Note

Issuing a credit/debit note is the only legal method for canceling, refunding, or modifying a validated invoice. Make sure to register the payment afterward if money is being refunded to the customer and/or validate the return if a storable product is being returned.

Issue a customer credit note

In most cases, credit notes are created directly from the corresponding invoices. To do so, go to Accounting ‣ Customers ‣ Invoices, open the relevant Invoice, and click Credit Note.

In the Credit Note window, fill in the Reason displayed on Credit Note and update the Journal and Reversal date if needed. There are two options:

• Click Reverse to open a draft credit note prefilled with the exact details from the original invoice. Update the Product and Quantity and click Confirm. This option allows for a partial refund or modifications to the credit note.

• Click Reverse and Create invoice to create a credit note, validate it automatically, reconcile it with the related invoice, and open a new draft invoice prefilled with the exact details from the original invoice.

To create a credit note from scratch, go to Accounting ‣ Customers ‣ Credit Notes, and click New. Filling out a credit note follows the same process as completing an invoice.
