Great to have you here, sachin-awasthigr.

If you are trying to import the client invoices to their new QuickBooks Online (QBO) version, we can import multiple invoices in one go. Before importing them, make sure everything looks good in your spreadsheet. Here's how: 

1. Fill in the required columns such as the Invoice number, Customer, Invoice date, Due date, Item amount, and the Item tax code. If your invoices have multiple line items, make sure each line entry has an invoice number, customer, invoice date, etc. just like in the sample spreadsheet.
2. If you collect taxes, add the tax rate in your invoices in the spreadsheet. When importing, you can map the tax codes you created into QuickBooks tax codes.
3. You can map each of your column headings to the invoice fields during the import. Take a look at what's required to import invoices or download this sample spreadsheet. If your spreadsheet has new products or services it can be edited after importing.

Then, follow the next steps in the Import multiple invoices at once article to finish the process. To learn what data you can bring over to QBO, and how to import your data, see the Import data from other software into QuickBooks Online article for more details.

Feel free to visit our Importing and Exporting Data page for more insights about managing your data to QuickBooks.

I'd like to know how you get on after trying the steps, as I want to ensure this is resolved for you. Just reply to this post and I'll get back to you. Take care always.
