Sole Source Procurement: Zend/PHP Environment for IBM iSeries

The Texas State Board of Public Accountancy (TSBPA) is conducting a proprietary sole source procurement for Zend/PHP software maintenance and support, identified by solicitation number 457-27-004. This procurement is necessary to maintain the agency's existing web and mobile application infrastructure, as the Zend Server is the only software that runs natively on TSBPA's IBM iSeries servers. Because the Zend/PHP platform is proprietary and requires specialized development knowledge, Perforce has been identified as the sole source provider capable of meeting these technical requirements. This action is being taken under Section 2155.067 of the Texas Government Code and the DIR Software Maintenance Exemption. The total estimated value for this procurement is 17,036.66 dollars, with a purchase order intended to remain valid through October 24, 2027. To be considered for the award, bids must conform exactly to the specified brand name, make, and model numbers. The solicitation was posted on September 28, 2026, with a response deadline of October 13, 2026. Brian O'Neal serves as the primary point of contact for this action, which is categorized under NAICS code 518210.
