Can I sue a company for not paying us

Good afternoon My business partner who is also a wounded Veteran like me funded this project and house. We're known across the state for hiring vets and working for larger companies like Pulte etc. My business partner informed me yesterday that after 2 weeks he would have our company lawyer file a mechanics lien to hold all projects for Iqon/ Integra until the $2500 is paid to us which we have had done and is now been a month. I have no ill will towards anyone and since this is business, payment on time is very important. Especially to two veterans that are paying out of pocket to run this company from time served. I let Mike know yesterday that today would be that last day to pay our invoice otherwise further communication would be between my business partner if not the company lawyer. I hate that it's come to this. It also says on our site that failure to pay for our service within 24 hours of a specific time would result in potential removal of the insulation since it's still ours and legal action to be taken and the contract signed makes automatically goes into affect. Since I've worked with our client before in that past, I gave him the benefit of the doubt. But ignoring a good company like us especially veteran owned and waiting to pay if at all is not good business. Regardless, thank you for the chance to work with you. I just wish it was under better circumstances. I'll stay respectful through the whole process and have been since starting this project. Please let me know your thoughts on all of this or how we can correct this situation. Joseph Toney Ceo Militarygradeinsulation@gmail.com https://www.militarygradeinsulation.com
