No. We only sign contracts if it’s what you want. We typically bill every month. Some clients are billed hourly, some hire efficient on monthly retainer. The only things binding us together in a business relationship are the results we deliver each month. If you ever want to sever our relationship, all you have to do is notify us. We’ll cease work immediately and send your final invoice. We agree to as much via email, which is just as good as a signed contract, legally speaking.
