In their own words
Aibidia
Aibidia is a web platform for managing the transfer pricing lifecycle, with compliance, operational transfer pricing, and research tools. Its shared data hub brings company and third-party information together. Data Solutions can import Excel and ERP data, then structure and aggregate it with customizable rules and mappings. The compliance solution generates editable Word local files in bulk from central data, with country-specific requirements and collaboration workflows. TP Aurora answers transfer pricing questions using curated IBFD content and OECD guidelines, with citations and links to source documents; its research coverage spans more than 100 tax jurisdictions. The 30-day TP Aurora trial includes 10 questions with full answers and source documents. It is intended for in-house tax and transfer pricing teams, specialists, and advisers. TP Aurora does not conduct benchmarking studies and excludes Pillar Two, Public CbCR, CSRD, and VAT. Aibidia was founded in Finland in 2018 and is headquartered in Helsinki. Pricing is on request; there is no free plan.
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.
