Can I downgrade my plan from Easy Start to Self Employed

QBSE is a stand alone product and no migration path yet. You have to open a new QBSE account and cancel your QBO EasyStart. Make sure to click the Buy button to get the discounted price for up to 3 months. If you purchase from the trial account, you have to pay the regular price.
