ISO 17100 Certified Translation Company in Lisbon

M21Global combines three factors that distinguish a translation company from an ad-hoc solution: independent certification, specialised team and fast response. Our ISO 17100 certification, audited annually by Bureau Veritas, requires clear separation between translator and reviewer, documented linguist qualifications, structured terminology management and full traceability of every project. It is not a badge: it is a system that translates into measurable consistency over time.

For companies with recurring needs, we offer managed accounts, annual contracts with fixed unit rates, client-specific NDAs, tailored workflows and integration with internal systems. Our continuous improvement practice applies quarterly reviews of operational processes based on client feedback. Small accumulated adjustments produce material gains throughout the year.

The ISO 17100:2015 standard defines the TEP process (Translation, Editing, Proofreading): translation by a qualified native linguist, editing by a second independent linguist, and final review before delivery. It is not an optional step. In M21Global's Strategic tier, every project follows the full TEP cycle. In the Standard tier, we apply translation with automated QA and sample-based review, fit for projects where the cost-time balance justifies it.

Alongside the process, we maintain translation memories, terminology glossaries and per-client knowledge bases. Files are prepared in standard XLIFF format and translated in CAT (Computer-Assisted Translation) environments with automated QA that detects inconsistencies in terminology, formatting, numbers, dates and tags. Our Zero Errors, Total Satisfaction philosophy sums up the commitment: any error flagged by a client triggers a process review, not just a document fix.

We use CAT (Computer-Assisted Translation) platforms with shared per-client memory bases, validated terminology glossaries and automated QA that checks terminological consistency, numbers, dates, formatting and tags in every segment. Integration with our production environment allows repeated segments to be reused. Match-based discounts reduce unit cost on high-volume projects without compromising quality.

Information security is treated as a mandatory dimension, not an accessory. We operate under least-privilege access, encrypted connections on every transfer, access logging and a documented chain of custody. We comply fully with GDPR for projects involving personal data, and we offer specific NDAs for sensitive content. Workflows can be tailored to client requirements, including isolated environments or processes with third-party validation.

M21Global is headquartered in Lisbon, with physical offices where project coordination, document authentication and on-site client support take place. The international team includes native linguists in key markets (United Kingdom, United States, France, Spain, Germany, Brazil, Angola and Mozambique) and strategic partnerships in Asia for languages such as Mandarin, Japanese and Arabic.

This distributed presence allows us to cover projects across every relevant time zone, keep linguists with up-to-date cultural fluency in each market and respond to urgent requests outside European business hours. For clients with operations in multiple geographies, we offer centralised coordination with localised delivery. Explore our full coverage on languages we translate.
