When I try to add a new customer, I’m getting a notification saying there’s a problem with my subscription each time I press Save. I’m paying a subscription.

Hi there. I want to ensure you'll be able to add your customer to QuickBooks Online (QBO).

To start, let's verify your subscription status by going to the Billing & Subscription page. Here's how:

1. Log in to your QBO account as a primary admin.
2. Next, click the Settings icon and select Account and Settings.
3. Then, select Billing & Subscription.
4. From there, check if you still have an active subscription. 

For reference, check out this article: Manage billing, payment, and subscription info in QuickBooks Online. 

If confirmed that you have an active one, we can perform the process of adding your customer by logging in to a private browser. This will provide you with a clean slate to help us determine if this is a browser-related issue. 

Below are the shortcut keys you can use:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + N
• Safari: press Command + Shift +N

Once signed in, add a customer again and save it. If you're able to do so, go back to your regular browser and clear the cache to eliminate the piled-up data. If the same thing happens, I recommend using another supported browser or device. 

However, if you still receive the same error, I suggest reaching out to our Phone support team to further investigate it. They can pull up your account in a secure place and check your subscription. They can also provide an additional set of steps to help add the customer.

Please know that you can always post here in the Community if you have any other concerns about managing your customers. Have a good one and stay safe.
