If you can somehow include Phone number and customer email on the invoices. Also give the option to include the notes from customer intake information in the customer data base when customers are input into the system. For example: When putting an estimate or invoice together, we have to back out of the invoice, go into customer info and copy and paste information and go back into the invoice. The customers information is usually input at time of appointment booking. I don't create an invoice until day of service. Having to back out of estimate or invoice to copy and paste input information in from customer notes is sometimes hard with internet connections etc.
