We have a customer who signed an agreement with us on 10/15/2019 to perform some work at their commercial building. We were told we could complete it installation on 12/2/2019. The customer ran into issues with his General Contractor and permits and is not allowing us to complete our scope of work. We have asked the customer to at least pay a progress payment to cover the cost of the materials do to this delay. As of today, we have only received one small payment which did not even cover the cost of materials. The customer is now telling us there will be an at least another month delay due to the COVID-19 order. Can you please advise what rights we have in regards to collecting this debt that has been outstanding since December 2, 2019?
