This study develops and empirically evaluates a socio-technical trust-by-design model for AI-augmented procurement negotiation systems. It jointly considers perceived transparency\/explainability (XAI), ethical governance visibility, and human-in-the-loop (HIL) relational design as conceptually distinct levers of AI system trust\u2014that is, professionals\u2019 willingness to rely on an AI negotiation system and their belief that it behaves competently and responsibly. AI system trust is treated as a focal proximal outcome, not as a proxy for, or a sufficient explanation of, dyadic buyer\u2013supplier trust. Using an exploratory sequential mixed-methods approach\u2014six multi-sector case studies across the EU and ASEAN regions (36 interviews) followed by a purposively recruited cross-sectional survey of 238 AI-exposed professionals analyzed via structural equation modeling (SEM)\u2014we find that AI use is associated with higher perceived negotiation efficiency, but also with lower AI system trust when automation displaces relational cues and explanations are weak. XAI exhibits the strongest positive association with AI system trust, while HIL design and governance show additional positive associations. In an augmented specification, XAI and HIL statistically account for the AI use\u2013trust association. A small inverse-U pattern further suggests that moderate, well-governed AI use is associated with higher trust than very low or very high automation intensity. Multi-group analyses indicate stronger XAI\u2013trust associations in the EU and stronger HIL associations in ASEAN. These findings contribute to trust-in-AI and procurement research by (i) clarifying the boundary between trust in an AI system and trust in a buyer or supplier, (ii) specifying procurement-specific conditions\u2014confidentiality, auditability, and negotiation tacticity\u2014under which AI use can erode confidence in AI support, and (iii) offering a cautiously framed, evidence-consistent roadmap for trustworthy AI negotiation systems. The reported associations should be interpreted within a non-probability sample and do not establish population-representative effects or buyer\u2013supplier relationship outcomes.<\/jats:p>","DOI":"10.3389\/frai.2026.1752349","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T05:38:57Z","timestamp":1785476337000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Trust by design in AI-augmented procurement systems: the roles of explainability, governance, and human oversight"],"prefix":"10.3389","volume":"9","author":[{"given":"Raja","family":"Mejri","sequence":"first","affiliation":[{"name":"University of Jeddah","place":["Jeddah, Saudi Arabia"]},{"name":"LISEFE-Lab, Tunis El Manar University","place":["Tunis, Tunisia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameh","family":"Skhiri","sequence":"additional","affiliation":[{"name":"Department of Marketing, Faculty of Economic and Management Sciences of Nabeul, University of Carthage","place":["Nabeul, Tunisia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,31]]},"reference":[{"key":"ref1","first-page":"21","volume-title":"A research agenda for sales","author":"Agnihotri","year":"2021"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"1727","DOI":"10.1080\/10447318.2022.2050543","article-title":"Trust in AI and its role in the acceptance of AI technologies","volume":"39","author":"Choung","year":"2023","journal-title":"Int.
