# "Errors syncing invoice Error: Transactions with inventory (QCH) products can't be dated earlier than the Inventory Start Date for the product"
### **Introduction**
Syncing data between ServiceBox and QuickBooks Online (QBO) is essential for maintaining accurate financial records. However, conflicts can occasionally occur during the syncing process. This guide outlines steps to resolve such conflicts if you receive the following error message:
**"Error syncing invoice Error: Transactions with inventory (QCH) products can't be dated earlier than the Inventory Start Date for the product"**
### **To address this error, please follow these steps**
#### **1. Review Inventory Start Dates in QuickBooks Online**
- Log in to your QuickBooks Online account.
- Navigate to the **Sales** or **Products and Services** section.
- Locate the affected inventory product(s).
- Click **Edit**.
- Select **Starting value** to view the inventory start date.
Ensure you note the inventory start date for each affected item.

#### **2. Adjust the Transaction Date in ServiceBox**
Make sure invoice transaction dates in ServiceBox are not earlier than the inventory start dates for the corresponding products in QBO.
- Identify the invoice in ServiceBox that is causing the error.
- Check if the transaction date is earlier than the inventory start date of any product listed.
- If needed, adjust the transaction date in ServiceBox to fall on or after the inventory start date.
#### **3. Update Inventory Start Dates in QBO**
If needed, modify the start dates in QBO to accommodate the invoice transaction date in ServiceBox:
- Log in to your QBO account.
- Navigate to **Sales \> Products and Services**.
- Find the affected inventory product(s).
- Click **Edit** and then **Starting value**.
- Update the inventory start date so it matches or predates the invoice date in ServiceBox.

Ensure inventory dates accurately reflect when you began tracking inventory for that product.
#### 
#### **4. Resync the Invoice**
