What TGS ASA does

TGS ASA, legally Alberto Soares & Associados, SROC, and operating commercially as ASA SROC, is a Portugal-based professional services firm registered with the Ordem dos Revisores Oficiais de Contas (OROC) under number 276. The firm delivers statutory audit, voluntary audit and assurance, and a multi-disciplinary consultancy practice spanning management and business consulting, corporate and business valuation, tax arbitrage, financing solutions, and mergers and acquisitions advisory, alongside an Internationalization Support service for Portuguese companies seeking to expand abroad. Its three named partners — Manuel Alberto Soares (ROC #807, also a CAAD-registered Tax Arbitrator and CMVM-registered Investment Consultant), Isabel Clemente (ROC #1645), and Rui Montes Pinto (ROC #1574, ex-banking) — anchor a team the firm describes as multidisciplinary, combining statutory auditors, accountants, tax specialists, lawyers, and financial and management consultants.

The business operates on a professional services model with no proprietary technology platform: engagements are customized, quote-based, and delivered face-to-face through two offices in Lisbon (Rua Julieta Ferrão) and Leiria (Parque Empresarial Eirena). Pricing is not publicly disclosed and is negotiated per engagement; statutory audit work is recurring by mandate while consultancy and M&A work is typically project-based. The firm claims more than 20 years of operating experience, cross-sector coverage spanning commerce, agriculture, transport, logistics, industry, real estate, tourism, healthcare, hospitality, education, public services, and IT, and the capability to coordinate multinational audit engagements via a common enterprise platform for parent companies and subsidiaries.

The go-to-market motion is sales-led and reputation-driven: client acquisition rests on direct relationships, partner credentials, OROC/SROC registration, and referrals, with the asasroc.pt website serving as the primary informational channel. Customer evidence is sparse — only one named client engagement (UCP Research Centre for Communication and Culture under a European Commission-funded culture@work project) is documented — and there is no publicly disclosed revenue, headcount growth, funding, or M&A history, indicating a micro-scale (1-10 employees), partnership-owned professional corporation without external investment.
