I created an invoice manually then the customer sent payment to my bank account which is linked in QuickBooks - does the customer get an email automatically showing paid?

In QuickBooks Online, whether your customer receives an email notification when an invoice is marked as paid depends on your account settings and actions you take. Here’s how it typically works:

1. Email Notifications for Invoice Payments:
• By default, QuickBooks Online sends an email notification to your customer when you mark an invoice as paid through the system. The email will confirm the payment and provide details about the transaction.
2. Email Content:
• The email content is automatically generated by QuickBooks Online and typically includes:
• Confirmation that the invoice has been paid.
• Payment date.
• Payment amount.
• Transaction reference or receipt number.
• Your business information.
3. Customizing Email Content:
• You can partially customize the email message by adding a personalized message in the “Message to customer” field when marking the invoice as paid. However, you have limited control over the email’s overall appearance and format.
4. Partial Payments:
• When a customer sends a partial payment for an invoice, QuickBooks Online typically sends an email notification confirming that part of the invoice has been paid. The email will specify the partial payment amount and date.
5. Payment Notification Settings:
• You can customize your payment notification settings within QuickBooks Online. To do this:
• Go to “Settings” (the gear icon) in the upper right.
• Select “Account and Settings.”
• Choose “Sales” on the left.
• In the “Online delivery” section, click “Customize” to set the message and email template for payment notifications.

Please note that the exact appearance and content of the email may vary slightly depending on your specific QuickBooks Online plan and settings. If you need more extensive customization of email notifications, you might consider integrating a third-party email platform or using a dedicated invoicing system to provide more flexibility in email templates and content.

Receiving an email receipt after paying an invoice is a great functionality, aaron.

Currently, QuickBooks Online doesn't automatically send an email confirmation to your customer after sending the payment. However, there is a workaround to achieve this. You can manually download the receipts and then email them to your customer. To do this, please follow the steps provided below.

1. Go to the Sales tab and then select All Sales.
2. Select Money received under the Type drop-down menu.
3. Locate the Payment transactions you want to send, then click View/Edit.
4. Click the Print menu. 
5. On the Print preview screen, click Download. 
6. Once done, email the downloaded PDF to your customer.

I can see how this functionality would be beneficial to your business. I encourage sending a feature request directly to our Product Development team. Doing so helps us improve the features of the program. I'll show you how:

1. Go to the Gear menu and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.
