Spec score 7.9 #6 of 28 in Transfer Pricing Software

What it is

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.
