Not every document needs the same level of translation. Choosing a more comprehensive service than the content requires wastes budget. Choosing an insufficient service for a critical document carries legal, regulatory, or reputational risk. The question is not which service is "best" in the abstract, but which is appropriate for each document type and its intended use.
What separates the three services in practice
M21Global structures its translation offer across three tiers: Standard, IAH+, and Strategic. Each combines human expertise, technology, and quality controls differently.
The Standard service involves one qualified linguist who translates and self-reviews the work, supported by translation memories and glossaries. Typical delivery is 3 to 5 working days. There is no independent review and no ISO 17100 certificate. For experienced linguists, the expected error rate is close to zero, but without an external reviewer, isolated errors can pass through. This service is appropriate for internal documentation: procedure manuals, interdepartmental reports, operational communications.
The IAH+ service (AI with Human Intelligence) combines machine translation with selective human review of approximately 30% of the segments most likely to contain errors. Delivery is within 24 hours, with an expected error rate of 5 to 15%. This tier is designed for high-volume reference content where speed is the priority and the impact of imprecision is low: product catalogues, FAQs, preliminary reports, internal technical documents.
The Strategic service deploys three linguists (translator, reviewer, and QA reviewer), follows the ISO 17100 audited workflow, includes two post-delivery revision rounds, full DTP, and a dedicated project manager with a 3-hour response time. The expected error rate is 0%. This is the appropriate service for high-stakes content: contracts, regulatory submissions, investor communications, external marketing, and compliance reports.
How to match documents to the right service
The decision rests on three concrete questions.
Who will use the document and for what purpose? An internal training manual never leaves the organisation. A contract with a foreign supplier may be submitted in court. A translated product page represents the brand to customers. The context of use determines the level of risk attached to each error.
What is the volume and how urgent is delivery? For large volumes with short deadlines and reference use, the IAH+ service is the most efficient option. For medium-sized internal documents without extreme urgency, the Standard service covers the requirement. For critical documents, regardless of volume, the Strategic service is the only option with a certified process guarantee.
Is there a certification requirement? Whenever a client, regulatory authority, or public body requires process documentation or ISO 17100 certification, only the Strategic service formally meets that requirement.
A common mistake is to treat all documents in a project the same way. In a market entry project, for example, contracts and external marketing materials justify the Strategic service; technical reference documentation can use IAH+; adapted internal procedures are well served by Standard.
Sectors where the wrong choice has consequences
In legal and regulatory work, a translation error in a contract or product certification dossier can invalidate documents, delay approvals, or trigger litigation. The cost of an urgent retranslation, plus any consequential damage, will typically exceed the cost of choosing the right service from the outset.
In pharmaceuticals and medical devices, authorities such as the EMA or national medicines agencies require high-precision translations for package leaflets, IFUs, and clinical reports. Regulatory compliance is not compatible with a 5 to 15% error rate.
In institutional communications and investor relations, a terminology error in an annual report or a shareholder presentation has a direct impact on organisational credibility.
In external marketing content, tone inconsistencies or localisation errors affect brand perception in markets where the organisation has no physical presence to compensate.
How M21Global helps with this decision
M21Global has worked with Portuguese and international companies for over 20 years.

Frequently Asked Questions
What is the difference between the Standard and Strategic translation services?
The Standard service involves one linguist who translates and self-reviews the work, with no independent review and no ISO 17100 certificate. The Strategic service deploys three linguists, follows the ISO 17100 audited workflow, and includes two post-delivery revision rounds, with an expected error rate of 0%.
When should I use IAH+ instead of Standard translation?
IAH+ is suitable when volume is high, deadlines are short, and the content is for reference use with low risk attached to imprecisions, such as catalogues, FAQs, or preliminary reports. Standard is better suited to medium-sized internal documents without extreme urgency.
Does the Strategic service include ISO 17100 certification?
Yes. The Strategic service follows the audited workflow in accordance with ISO 17100:2015, certified by Bureau Veritas. It is the only M21Global service tier that formally meets that requirement.
Can different service levels be used for documents within the same project?
Yes, and it is often the most efficient approach. In a market entry project, contracts and external marketing materials may justify the Strategic service, while internal technical or reference documentation can use IAH+ or Standard.
Is the IAH+ service suitable for regulatory or legal documents?
No. The IAH+ service has an expected error rate of 5 to 15%, which is not compatible with regulatory, legal, or clinical documentation. The Strategic service is the appropriate choice for those contexts.
