General journal entries are for transactions that are not related to customers or vendors. What kind of adjustments are you trying to make?

There are many adjustments that might happen, I'll just list some:

1- Adjust a receivable (Client) account with a payable (Vendor) account.

2- adjust two (Vendor) accounts with each other, ex: I supplies X to one of my vendors at cost, I'll just deduct it from his payment.

my solution was:

I made a "Contra-Account" in my chart of accounts, and everything is going from there.

adjust the payments/receiving from that account.

But if I can link the JVs it would be much easier and faster, plus better documented in my files (easier to print).

Your Vendor and Customer subsidiary records will be a mess and out of balance.  Steve is right, you cannot use a GJE to make these adjustments.

Try changing who you are paying. on the check.  If you look to the left of the vendor name, you will see a down arrow.  Switch it to customer. This feature is available on other screens too.  Maybe that will help.

The ledgers will never be a mess and out of balance, it is a Dr / Cr transaction.

They will balance each other.

I already have a solution that I'm using, I just wanted to see if linking the JVs is possible.
