I am a secondary company on desktop. The option to convert to online is not listed under Company. I need help please.

Hello there, shawsoutheast-ya.

Let me share some information with you about converting QuickBooks Desktop company file to QuickBooks Online.

Make sure QuickBooks is updated to the latest release and check if your company file isn't too big to export. Then, import your desktop file to QBO:

1. Sign in as an admin to the company file you need to import.
2. Go to the Company menu, then select Export Company File to QuickBooks Online.
3. Select Start your export.
4. Sign in as an admin to your QuickBooks Online company.
5. If you track inventory in QuickBooks Desktop:
   • Select Yes to bring them over, then specify the as of date.
   • Select No if you want to set up new items later in QuickBooks Online.

     Note: Only QuickBooks Online Plus and Advanced can track inventory. Both plans use the FIFO method.

6. Select the Choose online company▼ dropdown, and choose the QuickBooks Online company you want to be replaced by your company file.
7. Select Continue.
8. Enter “Agree” in the text field, then select Replace.
9. Select Yes, go ahead and replace the data, then select Replace.

I've also included some articles to learn more ways of handling your QuickBooks data:

• How to fix errors when converting from QuickBooks Desktop to QuickBooks Online.

I appreciate if you'd update me on how the steps work. I want to make sure everything is taken care of for you.
