I am a subcontractor in California, I have a customer that hasn't paid, and is over the deadline for payment, the job was bid at a way lower rate ask this was the contractors 1st job in California. They stiffed us on paying, can we bill in full the going rate in California? There was a verbal agreement which was said once the job is completed, you will be paid, and covid-19 happened and they are hiding behind a msa we signed for a 30-45 day payment and of course they are beyond the 30-45 days....
