This project has a bond, which our customer paid everything under the bond to the fund control except for $1000.00. We also billed this customer for a separate order related to this project as well. The fund control has now sent this money to the bond & now Hudson Surety has the funds that our customer paid to the fund control and has had these funds for a month or longer and is stating that they need a letter from our customer stating that they are done with the bond. We paid for the bond, but yet it is working against us. I am not familiar with this process as we have never done a bond on a project before. I am hoping you can give me some insight on what legally we need to do to get paid the money that the bond is holding and plus what is owed additional on this project that is not part of the bond. Project is in the State of Montana & we are in State of California
