Taking the pictures is only half of the process. All images go through an editing process to ensure the the following:
Images are delivered to you in two sizes:
You will receive an email with a link to an online gallery where the pictures can be seen and downloaded. This gallery is typically active for 30 days to give you plenty of time to download the images.
The email will also have a link to the invoice which can be paid online unless you chose to pay at the shoot. I don't require payment up front. My standard terms are 15 days from the shoot date. You're trusting me to make quality images of your listing. I trust you to pay the invoice. My accounting system will start nagging you automatically though after the 15 days. :)
Additionally, if you prefer, I can deliver the files via DropBox.
