In their own words
ONESOURCE Transfer Pricing
ONESOURCE Transfer Pricing is a web platform for multinational companies and tax teams managing transfer pricing policy, documentation, benchmarking, and reporting. Its modular coverage includes operational transfer pricing, country-by-country reporting, intercompany agreements, and documentation. Transfer Pricing Documenter supports comparable searches and centralized preparation of local-file and master-file materials; its benchmarking resources include more than 2 million curated private and public company records. BEPS Action Manager supports country data collection, risk analysis, and filing with local authorities. The Intercompany Agreements module includes reusable templates, e-signatures, alerts, signature tracking, dashboards, and document management. Operational Transfer Pricing can consolidate data from ERPs and other sources, monitor transactions through the year, support reporting, forecasting, and scenario exploration, and record who changed data and when. The platform also supports step-by-step analysis of related-party transactions and real-time collaboration. Pricing is available on request; the Singapore product page invites visitors to contact Thomson Reuters for product information or a demonstration, but states neither a price nor a trial duration. Optional professional support is available with Transfer Pricing Documenter.
TP/OS
TP/OS is transfer pricing documentation software from ArmsLength AI for advisory firms and multinational in-house tax teams. It organizes source facts, reuses templates, and supports drafting and annual documentation updates. The product supports Local Files and Master Files, with localized outputs in a customer-selected structure. Its assistant reads source files, fills supported placeholders, and flags omissions or contradictions for review. Teams can request missing information from colleagues, track progress, and review content before sharing. TP/OS exports editable Word files in the customer's house style. It runs on the web, with Base, Custom, and Turnkey plans priced on request. A guided trial covers one Local File prepared the prior year, for review of its output and next-year update. Setup depends on the customer's templates and documentation needs, and the company asks customers to confirm country scope and outputs with its team. ArmsLength AI says its security controls are ISO/IEC 27001 certified, project data is stored and processed in the EU, and customer inputs are not used to train foundation models. SSO/SAML is available through Microsoft Entra ID and Google.
