Delays in vendor payments within public © 2025 Original content from this work may be used under the terms of the creative commons attributes 4.0 License. sector organisations, especially with the procurement of assistive technology for individuals with disabilities, pose significant difficulties to service efficiency, equity, and operational responsibility. Conventional payment systems are impeded by human verification procedures, fragmented data flows, and regulatory obstacles that frequently prolong service delivery timelines. This study introduces a research-based system that utilizes blockchain-enabled smart contracts to enhance vendor payment processes and eradicate service delays in AT procurement. This report conducts a comprehensive examination of current payment infrastructures and regulatory frameworks, identifying significant failure points within the systems utilized by Departments of Rehabilitation (DOR) and other agencies. The proposed architecture utilizes smart contracts to automate payment authorization, ensure compliance, and openly and effectively enforce contract requirements. Incorporated within the smart contracts are policy-driven logic rules that reflect state procurement standards and Workforce Innovation and Opportunity Act (WIOA) fiscal guidelines, facilitating real-time verification of service milestones and secure cash distribution.

INTRODUCTION compliance integrity. Access to assistive technology (AT) is a fundamental This study presents a research-based solution that component in guaranteeing fair opportunities for addresses these issues through the application of individuals with disabilities (Smith & Zhao, 2023; U.S. blockchain-based smart contracts. Our findings Department of Education, 2025). These instruments— demonstrate that smart contracts can automate and comprising mobility aids, augmentative communication enforce vendor payment workflows in a way that devices, and adaptive software—facilitate autonomy, significantly reduces delays, eliminates redundant promote education, and enhance workforce paperwork, and ensures alignment with federal engagement (Miller et al., 2024). Nonetheless, public regulatory requirements. Smart contracts are self- sector procurement procedures, especially those executing digital agreements hosted on decentralized regulated by the Workforce Innovation and Opportunity ledgers, which initiate transactions—such as vendor Act (WIOA), have traditionally been sluggish and lacking payments—only when specific, pre-programmed transparency (Torres & Banerjee, 2024; Deloitte, 2020). conditions are met. Their transparent, tamper-proof Recent studies recognize decentralized technology as a structure makes them ideal for public sector use, where viable solution to procurement delays and fiscal accountability and audit compliance are essential. accountability deficiencies (Lee & Park, 2025; Our research involved an in-depth analysis of DOR Blumenthal et al., 2023). In this context, blockchain- workflows, vendor payment timelines, and compliance based smart contracts have arisen as an innovative chec
