My rule of thumb is simple. "Your (National Sign Company) inability to get paid from your client in a timely manner is not my problem." I probably do 10-15 jobs/year for these types of companies (normally large scale vinyl installation) and I've never had an issue getting paid quickly. Largest job last year of this type was 20,000sf of short term vinyl for the Republican National Convention at Quicken Loans Arena. Got paid in 7 days. They didn't like it, but I don't care.
