why is Accounts Receivable showing on the PL statement

Glad to have you here, Nathan. 

Accounts Receivable is a Balance Sheet account and shouldn't appear on a Profit & Loss report. This happens when transactions are incorrectly coded or the report is misconfigured. To fix this, you can check the following:

Verify the Accounting method. If set to Accrual, the P&L will show A/R immediately when created. If set to Cash, income only appears when payment is received.

Here's how:

1. Go to Reports
2. Select Profit and Loss
3. Then toggle it to Cash (click on it) if it's in Accrual accounting method.

Moreover, unpaid invoices under Cash accounting method will not show in your P&L report. However, using Undeposited funds (UF) to receive payments will be treated as received and will be recognized as income in your P&L report. 

You can also open the account register and check for transactions that were miscategorized (e.g., journal entries, expenses, or deposits incorrectly posted to A/R instead of an income/expense account). 

Please take note on the date range the P&L is covering, so you can see the types of transactions appear when you open the A/R line.
