Ask HN: Freelancers, how do you collect payments?

Those that don't use Elance, Odesk, etc, how do you collect payments?

[dossy]

The old fashioned way: invoices, usually emailed. Payments arrive in the form of paper checks, which get deposited. O. G. OLD SCHOOL.

I send an invoice.

I usually know right away if the customer will pay or not, since I always invoice every 2 weeks.
