Hi michelle!
Thank you for getting help with your Stripe/Mariana Tek data. I'd like to share some options with you.
We're unable to import your Stripe or Mariana Tek account to QBO. However, you can integrate your Stripe account to sync sales activity to QBO. If you really need to import your entire account's data, you can find a third-party app to do the transfer.
Alternatively, you can upload bank transactions to the Banking page, so you can categorize and add them to your books.
Don't hesitate to give us a shout if you need help along the way. Take care!
