Uploading an Excel file is only allowed for your lists of data such as names, accounts, and items. With this, let's create an IIF file of your vendor payments and import them into your company in QuickBooks Desktop.
To begin with, here are the templates to create the IIF file depending on the payment method used:
Use this article to read and learn more about the template: IIF Overview - Import Kit, Sample Files, and Headers.
Once the file is created, use the import utility tool to upload the list of vendor payments created: Export, Import, and Edit IIF Files in QuickBooks Desktop.
I'm also including this reference with useful articles while working with the import utility tool: Import and Export Data in QuickBooks Desktop.
I've got you covered if you have questions about uploading a list of transactions. Use the Reply option below to leave a comment. Take care always!
