When teams come to us

An LSP needs overflow capacity and their existing vendor pool cannot cover the language spread, volume, or deadline
A rare-language request lands on the desk and no marketplace translators exist for the pair
A regulated content program needs higher accuracy than machine translation post-editing can deliver (see our guide on when to use human vs machine translation)
A new market launch requires terminology built from zero in languages with no existing glossary or reference material
A multilingual program needs consistency controls across 15+ languages with shared terminology and style

Who this is for

Head of Localization / Vendor Manager at LSP

You need dependable white-label translation capacity for overflow programs, especially in language pairs your current vendors cannot cover.

Program Manager at LSP

You need a subcontractor who can scale rare-language delivery without your team managing individual freelancers across multiple time zones.

Director of Global Content

You need human translation with review workflows for regulated, sensitive, or brand-critical content where machine translation is not acceptable.

Procurement Manager

You need an ISO-certified vendor with penalty-clause SLA readiness who can pass compliance checks and deliver at production scale.

Translation services we deliver

Rare-language human translation

Translation across 300+ languages including ultra-low-resource pairs where MoniSa builds linguist teams from community networks. We have worked in languages with extremely limited translator availability worldwide.

Terminology creation and glossary development

For domains with no existing glossary — scripture, indigenous-language publishing, niche technical fields — MoniSa builds terminology from zero. Glossaries are validated with domain authorities and community reviewers before production begins.

White-label translation capacity

Clean white-label execution for LSP overflow and channel programs. No MoniSa branding in deliverables. Your client sees your brand, your QA standards, your reporting. We execute behind the scenes.

Regulated and domain-specific translation

Legal, medical, technical, and financial translation with domain-matched linguists. Legal translation requires more than language proficiency — it requires terminology precision and regulatory awareness.

Multi-language program management

Single-point program management across 15+ languages with shared glossaries, style guides, and cross-language consistency checks. One PM coordinates everything — you deal with one person.

How our translation workflow works

step 1

Scope and match

Language pairs, domain, volume, quality tier, and timeline are mapped before assignment. Translators are matched by domain expertise, not just language proficiency.

step 2

Terminology setup

Glossaries, style guides, and do-not-translate lists are built or reviewed before production. For new domains, terminology is created and validated with subject-matter experts.

step 3

Translate and review

Translation follows a structured TEP (Translation, Editing, Proofreading) workflow. Every project includes at least two review layers. Rare-language projects include community validation when the content is culturally sensitive.

step 4

Quality governance

Cross-language consistency checks, terminology adherence scoring, and error trend analysis. Quality metrics are tracked per linguist and per language pair.

step 5

Deliver and report

Batch delivery with full QA reports. Linguist performance data and error patterns shared on cadence for ongoing programs.

TEP workflow with domain matching

LAYER 1

Translator

Domain-matched translator produces the initial translation using approved glossaries and style guides. Every translator is vetted for subject-matter competence before assignment.

LAYER 2

Editor

Bilingual editor reviews for accuracy, terminology adherence, and fluency. Edits are tracked and fed back to the translator so the same mistakes do not repeat.

LAYER 3

Proofreader

Final review for grammar, formatting, and consistency. Cross-language consistency checks run across all target languages in multi-language programs.

ISO certified: ISO 9001:2015 (Quality Management), ISO 27001:2013 (Information Security), ISO 17100:2015 (Translation Services).

White-label compliance: NDAs with every linguist. No MoniSa branding in client-facing deliverables. Access controls scoped by project role.

Security posture: GDPR-aligned data handling. Encrypted data in transit and at rest. All linguists sign confidentiality agreements.

SLA readiness: Production programs run on penalty-clause SLAs with governed delivery schedules. Turnaround commitments are contractual.

Proof

A rare-language translation program shipped across 8 languages and 4 scripts that most vendors could not staff

Problem –

A global technology company needed translation, editing, and proofreading across Batak Karo, Pangasinan, Santali, Sylheti, Maranao, Banjar, Moroccan Arabic, and Ahirani — spanning 4 writing systems. Standard sourcing could not produce qualified translators for any of the required pairs.

What we did –

MoniSa sourced translators for all 8 pairs through community networks, built terminology from scratch, and delivered in structured batches with cross-language consistency checks.

Result –

257,000 words delivered in 10 days at 99.8% accuracy with minimal revisions.

A rare-language evaluation program met its deadline when other vendors could not source linguists for the required pairs

Problem –

An evaluation program required translation and quality scoring across Marshallese, Hmong, Hawaiian, Maori, Palauan, and Tahitian. Finding qualified linguists in these languages takes months through standard sourcing channels.

What we did –

MoniSa sourced rare-language linguists through community networks, built evaluation protocols from scratch, and delivered in structured batches with cross-language consistency checks.

Result –

The evaluation shipped on a 25-day timeline that other vendors quoted months for. 789,000 words at 99.5% linguistic accuracy across 10+ rare languages.

Frequently asked questions

How do you handle languages where no marketplace translators exist?

We recruit from community networks, not freelancer platforms. For ultra-low-resource languages, sourcing starts at the community level — diaspora networks, academic institutions, religious organizations. We have delivered translation in languages with extremely limited translator availability worldwide.

Can you build terminology from zero for a domain with no existing glossary?

Yes. We build glossaries, do-not-translate lists, and style guides from zero for domains with no usable reference material. Terminology is validated with domain authorities and community reviewers before production begins.

We need white-label capacity. Will your brand show up anywhere in the delivery?

No. White-label programs run under your brand. MoniSa does not appear in deliverables, reports, or any client-facing communication. NDAs and confidentiality agreements are standard.

How do you ensure consistency across 15+ rare languages in one program?

Shared glossaries and style guides enforced across all languages. Cross-language consistency checks in every batch. One program manager coordinates all language pairs. Terminology adherence is scored and tracked per linguist.

What domains do you cover?

Legal, medical, technical, financial, marketing, scripture, and general content. Translators are matched by domain expertise, not just language proficiency. Domain-specific glossaries are built or reviewed before production begins.

What certifications do you hold for translation work?

ISO 9001:2015 (Quality Management), ISO 27001:2013 (Information Security), and ISO 17100:2015 (Translation Services). ISO 17100 is the international standard specifically for translation service providers.
