I need help in my proposals/contracts figuring out how to word project management hours to ensure I'm getting paid for that time, but not throwing the builder under the bus as that is an important relationship for my business. The scenario - custom home builder refers me to client, they want selections assistance, some drawings etc., I know the builder will call me for plumbing and electric walk thrus and not look at my deliverables prior... so say in 6 months I will doing site walk thrus etc. and need to bill the client for it.......For larger long term projects like ground up custom homes do you charge a retainer then bill against that and then hourly? .... and how do you word it that the client doesn't feel they are paying you to do the builders job? Thank you all!
