Payment stubs

I am testing out zoho books as I search for a good accounting system. I would like to include payment stubs with my invoices. But the invoice system is set up really wastefully leaving a lot of blank space in page one of the invoice, attaching the payment stub at the bottom of page 1 cutting your invoice detail in half, and then ending the rest of your summary on page 2. This looks really unprofessional. Why is it not set up to include the invoice at the end of the invoice details instead of cutting through the invoice? And why does the template waste so much space? The Bill to and Ship to areas should be columned next to eachother horizontally to save space instead of stacked vertically. Is this easy to fix?
