# Credit Memo transaction sync (NetSuite to Zuora)

> Integration that syncs NetSuite credit memos to Zuora invoice item adjustments

Integration that syncs NetSuite credit memos to Zuora invoice item adjustments

## Overview

This integration syncs **NetSuite credit memos to Zuora invoice item adjustments**. NetSuite Connector considers two types of credit memos: Standard and negative balance. The credit memo integration is actually implemented as two separate syncs, NetSuite credit memos to Zuora and NetSuite credit memos (negative balance) to Zuora.

See [Credit Memo Transaction Sync (Invoice Settlement Enabled)](/docs/platform/integration/integration-hub/advanced-connectors/billing-connector-for-netsuite-gl/integration-between-zuora-and-netsuite/credit-memo-transaction-sync-invoice-settlement-enabled) for information about the integration that syncs **Zuora credit memos to NetSuite credit memos** when Invoice Settlement is enabled for your Zuora tenant.

## About the Credit Memo sync

* The standard use case is that within NetSuite a user creates a credit memo against a Zuora invoice with an available balance. The credit memo must reference an item. However, that item is not actually synced to Zuora because the sync creates a transaction-level invoice item adjustment.
* NetSuite Connector syncs only credit memos applied to an invoice that originated in Zuora.
* The credit memo must be fully applied.
* NetSuite Connector cannot create an invoice item adjustment because there is no guarantee that the item referenced on the NetSuite credit memo was referenced on the original Zuora invoice.
* The invoice item adjustment will be created in Zuora without an accounting code.
* If a credit memo is unapplied after it has been synced, you must reconcile manually.
* Review the [Transaction sync preferences](/docs/platform/integration/integration-hub/advanced-connectors/billing-connector-for-netsuite-gl/install-netsuite-connector/configure-sync-preferences). These preferences are important and control the behavior and data mapping of the sync, including the credit memo number.

You can disable both credit memo syncs from the NetSuite [Connector advanced settings](/docs/platform/integration/integration-hub/advanced-connectors/billing-connector-for-netsuite-gl/install-netsuite-connector/configure-advanced-settings). However, you should disable this only under the guidance of Zuora Services.

> **Note**

> The credit memo sync processes from NetSuite to Zuora is disabled by default. Use the [Advanced settings](/docs/platform/integration/integration-hub/advanced-connectors/billing-connector-for-netsuite-gl/install-netsuite-connector/configure-advanced-settings)to enable these sync processes.
