We are a Memphis, TN based flooring company and provide new flooring installations as requested for apartment communities. We provide services to two Florida properties managed and owned by the same company with large past due balances. We are new to Florida and have never been required to send a Preliminary Notice at 45 days - since each installation is a different job, does that 45 days start from the very first installation, or after each one? Does the preliminary notice requirement even apply to us? We do require new customers to sign a credit application that outlines our 30 day terms and the potential consequences of leaving balances unpaid, and the owner information is listed on that signed application - does that cover us as "contracted with the owner?" Is there a way for us to file a lien?
