Can I get more than 90 days of data from my Amazon Seller Central account loaded into Quickbooks Online using the Amazon Seller Connector?

Hello there, support-boxmetho. I understand the importance of having your transaction from Amazon accurately recorded in QuickBooks Online (QBO). 

QuickBooks Online (QBO) is built with the ability to connect with a variety of institutions to import transactions. However, there's no option to upload Amazon data in the App transaction. 

On the other hand, you can explore third-party importer tools to get the older transaction. Otherwise, you'll have to manually enter them. Here's how:

1. Go to the +New icon.
2. Select the transaction type you want to enter.

Alternatively, you can enter your transaction directly though the register: Manually add transactions to account registers in QuickBooks Online

Additionally, you can categorize your transactions to manage them before the reconciliation process. 

Keep us posted if  you have other concerns in importing your transaction and other QuickBooks-related. We're ready to help you and address it to help you manage your account smoothly in QuickBooks. Have a nice day!

You may need to use a paid connector as the workaround.
