I have many accouts recivable transactions showing up in my profit loss statement. how do i clear them out from a previous book keeper who never recorded the payment?

Hello there, @wilkestechnologi 

Let’s open the bank feed payment (deposit) entry in your Bank Register. Then post it to Accounts Receivable to clear the invoices. I'll show you how.

Here's how:

1. From the left menu, select Accounting. 
2. Choose Chart of Accounts, then find the account you deposited the payments to and click View Register.
3. Locate and pick the correct deposit, then hit Edit.
4. Go to Add funds to this deposit, then find the fund you need to edit.
5. In the Receive From column, choose a customer name.
6. In the Account box, select Accounts Receivable.
7. Hit Save and close.

After editing the deposit, let's apply the deposit entry as an invoice payment.

Here's how:

1. Go to the New (+) icon, then choose Receive Payment.
2. Select the customer's name, then add the Payment date.
3. Under Outstanding transactions, choose the Invoice you need to mark as paid. 
4. In the Credits, select the Deposit entry and hit Save and close.
