I am working on a NSF and on the expense there is not a place to record customer name (on form by account type etc.) How can I add customer expense form?

You can only include customers in Accounts Receivable transactions, Wakelu. However, I know a way we can enter your NSF in QuickBooks Online (QBO) that I can share with you.

Before doing so, know that the steps are complex and may impact your financial records. Consulting with an accountant is highly recommended. If you are without an accountant, you can locate one through this website: Find a QuickBooks ProAdvisor.

Let's begin by recategorizing the bounced payment to reopen the invoice. This will generate an expense, reflecting the deduction in your financial records and maintaining their accuracy. You can do so by following the steps below:

1. Log into your QBO account.
2. Go to Transactions, then choose Bank Transactions.
3. Look for the bounced check or returned payment in the bank feed, then click it to expand the transaction details.
4. Select the customer whose payment bounced in the Vendor/Customer ▼ dropdown.
5. Choose Accounts Receivable in the Account ▼ dropdown.
6. Once done, select Add.
 

This transaction offset the unpaid invoice. If your bank isn't connected to QuickBooks or the returned payment hasn't shown up, you can create an expense for it now and match it to your bank records later. After that, let's unapplied the bounced check payment from the original invoice.
 

Here's how:
 

1. Go to Sales, then choose Customers.
2. Find and select the customer whose payment bounced. Then, look for the bounced check and click the pencil icon to Edit.
3. Choose the payment made link. 
4. Remove the checkmark from the box corresponding to the invoice where the payment was allocated.
5. Select the new expense you created in Step 1. Then, click Save and close.
6. Select Yes if a prompt with a message that the transaction is connected will appear.
 

Subsequently, you'll need to generate an invoice for the bank fees to bill your customer. Please refer to Step 3 outlined in this article: Record a returned payment or bounced check in QuickBooks Online.
 

Furthermore, keeping track of your financial records can be challenging. Our QuickBooks Live Expert Assisted team is ready to assist by delivering an in-depth analysis of your business performance and providing strategic counsel to facilitate your decision-making process.
 

After accepting their payment for the original invoice with bank fees, you can proceed with the standard procedure to receive their payment.
 

Consistency and precision are crucial for effective financial management. Keep in the loop if you have follow-up questions or concerns with any QBO-other aspect. I'm just a post away.
