Hi shzaz7,
Thank you for your post.
I've further checked this on our end and even replicated the issue. However, I am receiving the JPEG attachment along with the invoice. I've checked your account, and you're using the AccountRight product. It seems that you're accessing your file in the browser version.
In MYOB Business/Essentials, it'll allow you to attach documents to emailing invoices by going to Invoices >> Select the chosen invoice >> Select the email button. At the bottom of the send to customer window (under the message) is the option to add or upload the attachments. You can then select the attachment to send along with the invoice. This is the same process with AccountRight when attaching files when emailing invoices.
If you've done this process, the attached file should be included once your customer receives the sent invoice. To troubleshoot this, kindly clear the cache, log out of the account, and log back in. Then try to send the invoice with the attached file to your personal email to see if you'll experience the same issue.
Please let me know if you require any further assistance with this. I'm happy to assist.
Cheers,
Princess
