I expect milestone payments based on deliverables if the project is fixed bid. My schedule for invoicing is usually 1) retainer at start of project 2 & 3) milestones 1 and 2, which can be "tech design approval" and "dev complete" or whatever 4) launch or end-of-warranty closeout. As more of our projects are integration of our software with client systems, 2 and 3 are usually agreement on integration design and entry into integration testing. I've reduced fixed bid work due to some challenging client circumstances that drove too many change orders (I like about one per week) and have focused more on T&M with a not-to-exceed.
