We upgraded our Invoice format to include a tear-off portion on the lower 1/3 of the page.
The address at the top of the page match up with a #10 double window envelope and the address in the remittance portion matches up with a #9 double window envelope.
Your custom message still appears on the document, it is now located above the Billing/Service Address.
The option to include an invoice with your completed work order can be turned on in your company settings.
Bulk printing and emailing your invoices can be completed from the Invoice List page.
Next up: Remittance coupons on Customer Statements, an Income Report, and Payment Status options (open/deposited) for accurate reporting and account reconciliation.
