In Business Manager, PDF versions of invoices are attached to each invoice e-mail. If you need to re-send an invoice, you can either re-generate PDF invoice or take the existing PDF attachment.
To re-send an invoice with a renewed PDF attachment, go to Business Operations > Invoices > choose the invoice you need and click Resend. To re-send an invoice with a former PDF attachment, see Re-sending E-Mails Sent Previously.
