I have a relatively new company that primarily does low voltage cabling - structured cabling. Up until this point, the jobs have been lower than $10,000 in which we have completed the work, invoiced, and was then paid on the work completed. We just received a large job, over $100,000 total with materials and labor. What are the normal payment terms to ask for? I was planning on requiring 50% on acceptance (deposit), 40% when job is half over, and 10% when work is completed. The job will last approximately 3 months, so it is a relatively small timeframe for monthly billing, which is why I thought billing the 40% when job is half completed was good. Ideas?
