I AM UNABLE TO MAKE THE PAYMENT OF MY QUICKBOOKS PLUS FROM MY CARD, IT SHOWS THIS MESSAGE IN THE ERROR (ERROR CODE: -81903, TYPE: VALIDATION_ERROR)

I'm here to provide thorough assistance and guide you in resolving the error code you encountered, Najumhzk. Let's explore troubleshooting methods below so you can successfully proceed making a payment.

When QuickBooks Online (QBO) displays error code -81903, it indicates a validation issue where the system can't confirm or authenticate your payment details. First, carefully review your billing information to ensure all details are accurate.

If everything is correct, I recommend logging into your bank's website to check for important notifications, scheduled maintenance, or service disruptions.

If there are no issues with your financial institution, the problem could be browser-related. Excessive cache files sometimes cause unexpected behavior in the platform. Let's rectify this by opening your QBO account through a private or incognito window. Here are the keyboard shortcuts:
 

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

Then, attempt to update your card info. If this fixes the problem, clear your regular browser's cache and cookies to refresh the browsing data. Alternatively, you may utilize other supported browsers.
