A Tax International

What A Tax International does

A Tax International d.o.o. (ATI) is a privately held Slovenian multidisciplinary consulting firm headquartered at Cankarjeva cesta 3, Ljubljana, offering tax advisory, accounting, legal, finance, IT, and ESG services primarily to medium and large multinational companies, with a secondary client base of local Slovenian businesses. The company was founded by Azra Begič Milanez, a former PricewaterwaterhouseCoopers and KPMG professional, and is positioned by its own materials as delivering Big Four-quality work in a smaller, more flexible boutique setting. The service portfolio comprises nine lines spanning compliance (tax/VAT, transfer pricing, accounting, finance), digital business transformation (process mining, RPA, digital strategy), legal services, and ESG consulting supported by a proprietary ATI Power Apps ESG data collection tool built on Microsoft Power Apps technology.

The business model is professional services: engagement-based, quote-priced consulting with custom scope and optimized hour consumption. Revenue derives directly from consulting fees with no software licensing, subscription, or transaction-based streams disclosed. Go-to-market is sales-led and relationship-driven, relying on referrals, the partner network, and memberships in AmCham Slovenia, the German-Slovenian Chamber of Commerce, the British-Slovenian Chamber of Commerce, the KONDOR Global independent consulting network, and Prime Global Sustainability. The firm markets through a multilingual website (English, Slovenian, Croatian, German), an active LinkedIn presence, association events, and ESG-focused webinars. Operating geographies span Slovenia, the EU, Switzerland, and the broader CEE region, although ATI has only one disclosed office location (Ljubljana) and delivers cross-border work via partner network relationships.

Underlying technology is Microsoft-centric: the proprietary ATI Power Apps tool mirrors functionality of Microsoft Sustainability Manager and is customizable per client, while client-side accounting work supports posting in SAP, Navision, Pantheon, Vasco, and Nova systems. The firm holds IQNET certification for sustainability managers and is pursuing an Audit Institute license in Slovenia, signaling a credential-led approach to ESG and audit-adjacent mandates. No revenue, headcount, funding, or investor figures are disclosed in the source material.
