I'm pretty new to the photography business and it seems one day I'll come across a late paying client. It's a small job that costs $300 and the client has been late for almost a month. So, I'm hoping you guys can give me some advice on how to chase down the payment. Proper contracts and invoices are issued, and I've been consistently chasing via email or phone. So what can I do? I thought about approaching the police but I don't think it's correct right?
