How to Prepare Your Documents for Translation

Half the problems in a translation project start before the translator sees a single word. Most delays, cost overruns, and quality issues in translation are not translation problems — they are preparation problems. The principle is straightforward: garbage in, garbage out. A translator can only be as accurate as the source material and the brief they are given allow.

Why Preparation Is the Translator's Most Important Input

When a client sends a document without context — no explanation of its purpose, no indication of the audience, no guidance on tone — the translator is left to make assumptions. In a legal contract, an assumption about register or intent can produce a clause that reads differently from what was intended. In a marketing document, an assumption about tone can deliver copy that is technically correct but commercially flat.

Preparation is not bureaucracy. It is the mechanism through which your knowledge of your own document is transferred to the professional who will reconstruct it in another language. The more complete that transfer, the more accurate the result — and the fewer revision rounds you will need.

The Seven-Step Preparation Checklist

1. Send the Final Version — Not a Draft

Every revision you make to the source document after the translation has been delivered means rework. If the document is not finalised, wait until it is. Sending a draft and asking for changes mid-project multiplies cost and time — and introduces the risk of version mismatches between source and translation.

If changes are unavoidable, track them clearly and inform your agency as early as possible. The sooner they know, the better they can manage the impact.

2. Use Editable File Formats

Send Word documents, PowerPoint presentations, Excel files, or InDesign packages — not PDFs or scanned images. Editable source files allow the translator to work directly within the document structure, preserve your formatting, and return a finished file that is ready to use.

PDFs — particularly scanned PDFs — require conversion before translation can begin. That conversion process introduces formatting errors, extra handling time, and additional cost. Optical character recognition on scanned documents is imperfect; characters are misread, tables collapse, and layouts break. If a PDF is the only version available, flag this explicitly so the agency can account for it in their quote and timeline.

3. Provide Context: Purpose, Audience, and Tone

A legal contract submitted to a court requires different register, precision, and terminology than a summary of the same agreement prepared for a board presentation. A technical manual for field engineers reads differently from a quick-start guide for consumers. Without knowing what the document is for and who will read it, the translator is guessing.

Tell your agency: what this document will be used for, who the target audience is and what level of familiarity they have with the subject matter, and what tone is required — formal, conversational, technical, persuasive.

4. Share Your Glossary or Brand Terminology

If your organisation has established terminology — product names, service categories, technical definitions, preferred translations of industry-specific concepts — share it. Consistency across all your translated materials is only possible if the translator is working from the same approved vocabulary.

If you do not yet have a glossary, a good translation agency will help you build one as part of an ongoing relationship. The earlier you start, the more consistent your multilingual communications become across every document you produce.

5. Flag Ambiguous Sections and Internal Jargon

Every organisation has language that is internally understood but opaque to outsiders. Acronyms, abbreviations, internal project codes, legacy terminology, and shorthand that works in English may not translate cleanly — or at all — into another language.

Read your document as if you were an outsider and mark any passage that might cause confusion. Better still, annotate those passages with a brief explanation. This takes minutes for you and saves hours of clarification requests during the translation process.

6. Identify What Should Not Be Translated

Not everything in a document needs to be translated. Product names, registered trademarks, brand names, legal boilerplate retained in the original language for jurisdictional reasons, and certain proper nouns should often remain as they are.

Without explicit guidance, the translator must judge — and different translators may judge differently. List the terms and sections that should be left in the source language. This is particularly important for documents that will be filed with authorities or submitted to international bodies where terminology consistency is required.

7. Set a Realistic Deadline

Professional translation requires time. A two-stage process — translation followed by independent revision — cannot be meaningfully compressed below a threshold without compromising quality. Revision is where the majority of errors are caught; it is not an optional extra.

When clients ask for a document by tomorrow and the project genuinely requires three days, a reputable agency will tell you. Rushed timelines force shortcuts — and the shortcuts almost always affect the revision stage. If your document carries legal, financial, or reputational weight, set a deadline that allows the work to be done properly.

How Wordhub Makes Preparation Easy

Most of the friction around preparation comes from clients not knowing what information to provide and agencies not asking the right questions. At Wordhub, our project intake process is designed to surface everything we need before work begins. We ask about purpose, audience, tone, terminology, and deadline — so you do not have to know the right questions in advance.

We also offer translation memory and glossary management as standard for ongoing clients, which means that every project you send us builds on the terminology and style decisions established in previous ones. Consistency improves automatically as the relationship matures.
