We are a material supplier to a government project at the Smithsonian in DC. We feel as though our customer will not pay timely due to disputes on welding certification which was provided, but is being disputed by our customer.
There is an excellent Levelset blog on this subject matter, including an outline of the four steps you need to take to perfect your Miller Act Claim.
If you have any further questions, please let me know.
Sincerely,
Carlton
