Sole Source Letter_Duval County_10142026.pdf

This is a sole source letter from RT Lawrence Corporation to the Duval County Tax Collector's Office in Florida, dated October 14, 2026, establishing the company as the exclusive supplier for RTLFiRST software and integration services. The letter supports the Tax Collector's Office request for RTL system services related to check processing and bulk remittance of mail payments, including conversion from Manatron to GSG TaxSyst, procurement of 10 new scan modules, and upgrades to Version 8 software. RT Lawrence Corporation asserts that it is the sole provider capable of configuring and integrating OPEX scanning equipment within the RTLFiRST proprietary software environment, as this integration requires specialized knowledge of the system's architecture, configuration, and processing workflows to ensure proper system communication and accurate transaction processing.

The letter confirms RT Lawrence Corporation's exclusive position as the developer and supplier of the proprietary RTLFiRST remittance processing solution and as the only company capable of performing the necessary software configuration and integration services required for OPEX equipment to function within the RTLFiRST environment. While OPEX provides the scanning equipment itself, RT Lawrence Corporation maintains that no other entity possesses the technical capability to integrate that equipment into the RTLFiRST system. The correspondence is signed by John Phillips, Director of Remittance Solutions at RT Lawrence Corporation, and addresses Kevin Rock, Chief Operations Officer of the Duval County Tax Collector's Office.
