i need to find an easy way to do service sheets electronically...to cut back on paper and diaries etc...and so i have better records which will force me to do the paper work on the spot and not leave it for when i get back to the office or later in the week and i forget half the things i did.

i want to be able to visit a site get the customer to verify the visit sign off that the work was done and time spent on site and if the work work is not complete sign somehow so the service sheet can be included in the invoice.

or if i complete the work the same day i want to be able to invoice and email the invoice form their office or dinning room table...so that the extra 10/15 minutes to do the invoice is costed in while on site...
