Edit: I forgot to mention that you need to give him a hard cutoff date. I ran into this situation a few weeks ago with a family session. The family agreed to paying in full, viewed the invoice, and then ignored it. I reached out to the mom and said “if I do not receive payment by tomorrow at X time, I will not be able to add your booking to my calendar.” She paid ASAP. I think because I was polite and flexible multiple times, she thought I wouldn’t be serious about payment.

Since this is scheduled for December 2nd, I would give him until noon on Tuesday to pay.

Best of luck, let me know how it goes!

I would let him know “since this is the second time this booking was rescheduled less than 24 hours prior to the scheduled session time, I respectfully am going to have to take full payment prior to booking the rescheduled session.”

If he was serious, he would have no issue paying. I had to do this with one of my clients once and they paid in full.

This was my first official styled shoot, but a lot of my photographer friends in the wedding industry have attended others in the past and always said good things. This one was free but some of them in my city have a $150 fee, which I think is ridiculous.
