Automatic emails are not been sent out to my customers and tenants at the end of the month. I tried to troubleshooting and put my own email address but to no avail.

Hello there, Fatima.

There's an ongoing issue about customers not being able to receive the sales transaction email sent out from QuickBooks Online (QBO). Our engineers are working to get this fixed as soon as possible. 

As a workaround, you can link your Gmail account to use for sending invoices, send via Whatsapp and download the PDF to send manually using their email outside QBO.

In the meantime, I suggest reaching out to our support team so you'll be added as one of the affected list of users. 

Furthermore, learn how you record sales transactions in two ways. To know more details, read this article for more information: Record Invoice Payments In QuickBooks Online.

Please get back to us if you have any questions when sending sales transactions. We're always right here to
