How a standard user can log in to quickbooks on line to use it?

Hello, airsoilder.

Your newly added (Standard) user should accept your invitation to start using QuickBooks Online (QBO). Let me elaborate on this in detail below.

After adding/inviting a QBO user, they'll receive an invite to join your company. Ask them to select the Let’s go! link in the email. They can create a new Intuit Account or sign in if they already have one.

Please note that if your user sees a sign-in page, it’s because their email address is already used with an Intuit Account (could be for a different product). It’s fine for them to sign in with that email address if it’s theirs. If they’re not sure how, they can select I forgot my user ID or password.

Please see this article to learn more about managing user profiles in QBO: Add and manage users in QuickBooks Online.

Additionally, there are different options for user roles and access permissions in QBO. If you wish to know more about each of them, you may want to check out this article: User roles and access rights in QuickBooks Online.

If there's anything else you need in managing users in QBO, I'm always ready to help. Take care, and I wish you continued success.
