Dears,the trial version was expired and when i tried to subscribe i found an error 81622 . and now i can't take the offer of 50% . please i need help

I know the importance of being able to avail of the discount, Awad. Let me discuss the error 81622 and provide you with the steps for renewing your account.

The 50% discount is a one-time offer provided by QuickBooks, whether you choose to move from a trial account to a subscription or continue with an existing subscription. However, one potential cause of receiving this type of error is your billing information might be outdated. With this, I suggest updating them in Settings to continue with the subscription. 

Here's how: 

1. Go to the Gear icon, then Account and settings.
2. Select the Billing & subscription tab.
3. Under Payment method, choose Edit.
4. Enter the full credit card information by typing in the complete card number, name on the card, expiration date, and security code. Verify that the billing address in QuickBooks Online is the same one that appears on your credit card statement.
5. Select Save Changes.
