To keep your accountant updated when you send invoices to your customers by email, you can add the accountant as a recipient for all the invoicing emails.
Add accountant email address
In the Business center preview, go to Invoicing and then click or tap the settings gear in the upper right corner.
In the Settings panel, scroll down to Email Settings and click or tap Email to add a new row to the table
In that row, enter the email address for the person you want to receive copies of all the invoicing emails your business sends out, and then choose whether the accountant should receive the emails either as CC (carbon copy), or as BCC (blind carbon copy). If you don't want the recipient of the invoice to have access to your internal emails, choose BCC.
Click or tap the ellipses if you want to remove an email address from the list.
After you add an email address to this list, your accountant, and anyone else you add, will automatically be notified by email every time you send an invoice.
