Hey @rodriguez-anita0,
I’d be happy to help with combining your accounts. I’m including a couple of links with great info on how to move or merge data files and lists in the company you want to keep: Merge data files; Move lists to QuickBooks Online. This will help combine the data as quickly as possible.
Right now, the ability to merge two company data files into one company isn’t currently available in QuickBooks Online. Each company is created as a separate file and can't be merged.
I’d love to hear how it goes. If you have any more questions, feel free to ask. I’ll be here to help!
