An efficient solution for understanding content, preliminary analyses, or translation of large volumes with acceptable error margins.
- Advanced machine translation
- Focused human review

Translation Services for International Business
Our core services cover the document types most demanded by international clients operating in or with Portugal. Legal translation includes contracts, court filings, corporate governance documents and regulatory submissions. Technical translation covers manuals, datasheets, software documentation and CE conformity materials. Financial translation handles audit reports, annual accounts, prospectuses and compliance filings.
We also provide website localisation, marketing translation and certified translations with international legal validity. Every project is assigned to linguists who are native speakers of the target language and have demonstrable experience in the relevant sector.
Service Tiers to Match Your Needs
M21Global offers three service tiers designed to balance quality, speed and cost. IAH+ uses private neural machine translation engines (never free public tools) combined with professional post-editing under ISO 18587. This tier is ideal for high-volume content where speed and cost efficiency are priorities. Standard provides human translation by a single qualified linguist with self-review, suitable for general business correspondence and internal documentation.
Strategic follows the full TEP workflow: translation by a specialist linguist, independent review by a second linguist, and a final quality assurance pass. This tier is recommended for legal contracts, financial reports, regulatory filings and any content where terminological precision is critical. All tiers follow ISO 17100 certified processes.
Getting Started
Starting a project with M21Global is straightforward. Send your documents by email or through our secure upload platform and tell us the target language, deadline and any specific requirements. You will receive a detailed quote within 3 business hours, including word count, recommended service tier, price and delivery date.
Once approved, your project is assigned to a dedicated project manager and matched with the most suitable linguists for your sector and language pair. We deliver translations in your preferred format, ready for use. For recurring clients, we build and maintain translation memories and glossaries that reduce costs and improve consistency over time.

Each project is assigned to linguists with proven experience in the relevant sector and document type, ensuring accurate terminology and appropriate register.
