Welcome to the Community family. I’m here to help and share some insights on how you can get a discount for your two companies in QuickBooks Online (QBO).
QBO offers a discounted price for our first-time users. If you've availed for the 30 days free trial, the discounted price will be waived off once the trial ends.
As a way around, you can subscribe to a new QBO account to avail of our discounted price. To know our latest pricing list, visit our QuickBooks pricing page for reference. Please do know that one company file is equivalent to one QBO subscription.
Once you've to sign up for QBO, check out these articles that you can use for future reference. These links can guide you on how to sign and switch to multiple accounts with one login credential.
