I've migrated all my information from QB desktop to QB Online. All my payments from customers are not applied to the invoices

Hi there, accoounting,

Some data aren't converted when migrating from QuickBooks Desktop (QBDT) to Online. This could be the reason payments were unlinked in QuickBooks Online (QBO).

You can refer to this article: What to expect when you switch from QuickBooks Desktop to QuickBooks Online to know what data doesn't convert during the migration process.

You'll need to manually apply those payments to invoices. Here's how:

1. Click + New.
2. Select Receive Payment under Customers.
3. Enter the name of the customer to open customer invoices and outstanding credits.
4. Add the payment date.
5. Mark the invoice under Outstanding Transactions and the payment under Credits.
6. Click Save and close.

I'm also adding the The QuickBooks Guide to Converting QuickBooks Desktop to QuickBooks Online link for step-by-step guidance, visuals, tips, and hyperlinks in the conversion process.

Let me know if you have follow-up questions, and I'm always around to help you out.

What should be the problem or error as all invoices with linked payments and deposits from Online version not converted to Desktop version?

That's why the balances are off

Let me share some information about how invoices are converted, RodenA.

Normally, links between invoices and received payments in QBO are converted to QuickBooks Desktop. However, invoices that contain charges, credits, billable expenses, or time associated with sub-customers will be separated into one invoice per customer.

To isolate the issue you can try converting your file again using the migration tool. Make sure to use a supported web browser to avoid errors and unexpected behaviors during the conversion. When you're ready, here's how: 

1. On QuickBooks Desktop, go to File and select Close company.

2. Go back to your QBO file and then prepare it for export.

3. Convert your file again.
4. After it finishes, review your invoices and financial reports again to check if the amounts are accurate.

Take note the rounding differences in the two versions can also cause failed export of payments to specific invoices. When this happens, you'll have to correct the amount on the invoice and then apply for the payment.

Lastly, here are some resources that you can read to learn more about the conversion limitations and help set up your company file in QBDT:

Keep me posted with results as I want to ensure that everything is sorted for you. Have a pleasant day ahead.
