When working with a major production company or even indie film producers how do you make sure you get paid for services rendered or location rental? Do you require a letter of credit (for major producers) or maybe a credit card on file for smaller accounts? Do you get paid when services are performed or is there a billing cycle that you have to use? Is all of this negotiated when you are securing the contract (I assume contracts are needed to cover everyone's butt)? I have never operated a business where I needed a billing service or CPA to collect my fees but I need this information in order to get my business plan in order.
It does depend on who/what you're working with, but most of the time, you
a). do the work.
b). send them an invoice
c). 7/14/30/60/90 days later, accept payment or chase up payment
d). if payment doesn't come, send to a debt collector
Some people negotiate payment up front or partial payment and so on. It all depends. When you're dealing with corporate accounts, it can be payment due 90+ days from date of invoice, which usually ends up being 120+ days.
It's all part of the negotiating.
If you're talking about working as an employee in the business, payment is usually made at the end of the work week. This is often true too as a contractor, but you'll usually need to supply an invoice.
