We're also experiencing the -30000 error when attempting to merge customers.  We already called support & could not get help. We were told, they were looking into it for us.

It is close to a year later ...and apparently NO SOLUTION OR HELP. We get this error simply by trying to update client address. Help please.

Hi Robman,


Upon checking, the original ticket for this issue is already closed. We can do the basic browser troubleshooting steps and see if this gets rid of the error.


To start, you'll want to sign in to QuickBooks using a private browser. This step disables its extensions and stops the cache from saving your browsing history.

  • Google Chrome: Ctrl + Shift + N
  • MS Edge and Firefox: Ctrl + Shift + P
  • Safari: Command + Shift + N

If you don't see the error, you can go back to your regular browser and clear its cache. If not, please try other browsers to see if we get the same thing. If nothing really works, please contact our Support again to revisit this case.


Please feel to reach back out if you have other questions.
