On your Kickserv Quickbooks page, the error should be there under the error tab. In that error, the customer name or customer number should be there pointing you to the customer record. Typically, the problem is that the parent record name is already in your QBOE account and Kickserv is attempting to sync the parent and its child record to QBOE.

If this parent record is truly independent and unrelated to the same-named customer in QBOE  then you need to decide how to differentiate their names.

Suggestions:

1. Add a middle initial

2. put a number at the end of the name

3. add the street address to the name

The two customer records are to be the same customer

Now, if the two records are supposed to be the same record, but the record in QBOE was put there manually then what you need to do is the following:

Renaming the records

1. Remove the invoice from the Ready To Sync queue.  We don't want this invoice to sync just yet.

2. Use the Kickserv smart search feature and type C:#### in the search box.  That is C for customer record, then a colon, then the customer number in the error message.

3. In KSA add a big "X" to the front of the parent customer name.

Syncing them both to KSA

1. Navigate back to your QBOE account and do some minor updates to the customer record in question.

2. Come back to KSA and run the major global sync button

3. Once the sync is done check for any other sync errors that may have risen and handle them successfully. Run the sync again until there are no more errors to handle.

4. Now you should have both customer records in your KSA account.  The one from QBOE will have the green QB symbol next to its name and the KSA originated customer record will have a big "X" in front of it.

Merge X customer into the other 

1. Now, starting with the "X" customer record 

2. Click the dropdown for editing the customer and select merge

3. In the new merge contact page type the parent record's name (i.e. Big Duplicating Co.).

4. Ensure you have the correct winning parent record before proceeding there is no undoing this process. 

5. Press the green button [Merge contacts] and click OK.

Now, you can put the invoice for this customer back into the Ready To Sync queue and sync.

(Option B)

Another technique that's worked for me is to change the "Where do you want to edit your contacts?" setting (Settings -> Integrations -> Quickbooks) to "Edit Contacts in Quickbooks", sync, and then change it back to "Edit Contacts in Kickserv".

It should be that easy!
