How to Prepare Documents for Translation: A Practical Checklist to Save Time and Money

If you have ever sent documents to a translator or translation agency and received an unexpectedly high quote—or a complete file requiring three revisions—the problem likely began long before the translation was completed. The root of the problem often lies in the source document itself.
Most businesses and project managers focus on finding the right translator or translation company, negotiating prices, and setting deadlines. However, the most overlooked element in keeping translation projects on schedule and within budget is preparing the original documents properly. Poor preparation will silently increase costs, delay deliveries, and create friction at every stage of the workflow.
This guide will show you exactly how to prepare documents for translation by giving you a practical checklist, identifying common pitfalls, and clearly outlining how good preparation will speed up the entire process.

1. Why preparation directly affects translation costs

Translation is not simply replacing the words of one language with their equivalents in another. Every project has a workflow that must include file processing, terminology research, translation memory matching, quality assurance, and formatting. Each of these steps is affected—for better or worse—by the quality and condition of the source document.
Translators and translation companies often price projects based on word count, content complexity, and the amount of preparation work required on their part. When a document arrives with inconsistent formatting, text embedded in images, or a lack of terminology guidance, that extra work does not disappear—it is factored into the quote or incurred later as revision fees.
Consider two scenarios. In the first, a client submits a well-formatted Word document with a glossary, a profile of the target audience, and clear instructions. Translators can upload files to their Computer-Assisted Translation (CAT) tool immediately, refer to the glossary throughout, and deliver clean files on time. In the second scenario, a client sends a scanned PDF file without terminology guidance and with vague instructions. The translator must first convert the file, manually edit the formatting, send numerous emails seeking clarification, and carefully select terminology—all of which add many hours to the project.
The difference in cost and completion time between these two scenarios can be significant. The good news is that the first scenario is entirely achievable by following a simple process when preparing the documents you send for translation.

2. Document preparation checklist before translation

This translation preparation checklist includes six of the most important areas to address before you submit any documents for translation. Systematically applying each step will help you reduce translation costs, minimize revision cycles, and provide the translation team with everything they need to get started immediately.

👉 Clean and Consistent Formatting

Formatting issues are among the most common — and most avoidable — sources of extra cost in translation projects.
Before sending your document, take time to:

• Accept or remove all tracked changes and comments.
• Use consistent heading styles throughout.
• Remove or replace text embedded in images.
• Eliminate unnecessary blank lines, manual spacing, and rogue formatting.

A clean, consistently formatted document allows translation tools to process your content efficiently and gives translators a clear, unambiguous structure to work with.

👉 Use Editable File Formats

The file format you submit has a direct impact on how quickly and cost-effectively your project can be completed.
Preferred formats for most translation workflows include:

• .docx (Microsoft Word) — the most universally compatible format
• .xlsx (Excel spreadsheets)
• .pptx (PowerPoint presentations)
• .html or .xml (for web and software content)
• .txt or .csv (for simple or structured content)

Avoid submitting PDFs as your primary source file unless there is no alternative. PDFs are design-locked, meaning translators cannot edit them directly. A PDF must first be converted to an editable format. This conversion process frequently introduces formatting errors, broken layouts, and garbled text, especially with complex designs. The time spent cleaning up a converted PDF can add a substantial cost to your project.

👉 Build a Glossary or Terminology List

A glossary of terms is one of the highest-value investments you can make in a translation project — and it does not need to be complex to be effective.
What to include in your glossary:

• Industry-specific or technical terms that have a precise meaning in your field
• Brand names, product names, and service names — and whether they should be translated or kept in the source language
• Do-not-translate (DNT) items such as trademarks, slogans, or proprietary terms
• Preferred translations for recurring concepts to ensure consistency across documents and projects

👉 Define Your Target Audience Clearly

One of the most common oversights in translation project planning is treating the target language as a uniform entity. In practice, the same language can vary dramatically depending on the region, industry, and audience.
Before sending your documents for translation, provide your translator with the following information:

• Target locale (not just the language, but the specific country or region)
• Audience profile (age range, professional background, level of familiarity with the subject matter)
• Tone and register (formal, conversational, technical, friendly)
• Any stylistic preferences (active vs. passive voice, use of contractions, sentence length)

👉 Set Clear Deadlines and Scope

Translation projects that need to be done quickly cost more. This is simply a reality of how translation services are priced. Most agencies and freelancers charge a premium for expedited delivery, and the faster the turnaround required, the higher that premium tends to be.
Effective translation project planning means building in realistic timelines from the start. As a general rule:

• Allow at least one to two business days per 1,500 to 2,000 words for a standard translation
• Add buffer time for review, revision, and formatting after the translation is returned
• Communicate your deadline clearly at the briefing — not as an afterthought

Equally important is defining the scope of the project before the actual work begins. Mid-project additions and changes are a leading cause of cost overruns. If new pages, sections, or language pairs are added after translation has started, the project timeline and budget will have to be renegotiated. Whenever possible, finalize the source content before the translation team is briefed.

For large projects, consider breaking the work into phases. Translating and reviewing a document in sections allows you to catch issues early, give useful feedback, and reduce the risk of extensive revisions being necessary at the end.

3. Common Pitfalls in Translation File Preparation

Even experienced purchasers of translation services can do things that silently inflate their translation costs. Here are the most frequent pitfalls — and their consequences.

Sending a PDF instead of the source file. This is the single most common avoidable pitfall. As noted above, PDF conversion introduces formatting errors and adds processing time. Always send the original editable file.

Skipping the glossary for technical or legal content. Incorrect terminology in technical manuals, legal contracts, or medical documentation is not just an inconvenience for the reader— it can have serious consequences. A glossary is not optional for high-stakes content.

Giving vague instructions. Phrases like “just make it sound natural” or “translate it the usual way” are not precise enough for translators. It leads to questions such as the following: Natural-sounding in what context? Usual according to whose standard? Specific instructions produce consistent results; vague instructions produce unpredictable output.

Ignoring locale differences. Requesting “Spanish” without specifying the target region, or “Chinese” without clarifying Simplified or Traditional, forces translators to make assumptions. These assumptions may not align with your audience, leading to revision requests and added cost.

Making scope changes mid-project. Changing or adding content after translation has begun disrupts the translator’s workflow, potentially invalidates work already completed, and almost always results in additional charges. Finalize your content before the project starts.

4. How good preparation speeds up the translation workflow

The benefits of thorough preparation are not limited to cost reduction. They ripple through the entire translation process, compressing timelines and improving the quality of the final output.

👉 Reduced need for clarifications
When a translator has a clean file, a glossary, a target audience brief, and a clear scope, they can work from start to finish without stopping to ask questions. Every request for clarification exchanged between client and translator typically adds half a day or more to the project timeline. Eliminating unnecessary back-and-forth is one of the fastest ways to accelerate delivery.

👉 Faster CAT tool processing
Professional translation tools process clean, consistently formatted files far more efficiently than “messy” ones. Such tools can leverage translation memory — a database of previously translated sentence pairs— to automatically fill in repeated or similar content, which reduces both the word count billed and the time required.

👉 Smoother review and QA rounds
A well-prepared project produces a cleaner first draft, which means review cycles are shorter and require fewer iterations. Reviewers spend their time refining quality rather than correcting avoidable errors.

👉 Shorter overall project timeline
All of these individual gains compound. A project that might take ten business days with poor preparation may be completed in six or seven without any sacrifice in quality if the preparation is thorough.

5. Signs that your document is not ready for translation

Many businesses only realize there are problems with their source documents after the project has already begun, at which point revision costs and delays have already occurred. Before submitting your documents to a translation agency, check if you are experiencing one or more of the following signs:

• You still have Track Changes, internal comments, or multiple unmerged versions of the file.
• The document contains a lot of text within images, diagrams, infographics, or screenshots.
• Product names, feature names, slogans, or industry terminology have not been finalized.
• The source content is still being edited simultaneously by multiple departments.
• You have not clearly defined your target market, audience, and brand tone.
• You only have a PDF or scanned copy without the original editable file.

If two or more of the above are present, your project is likely to require additional processing time, Q&A sessions, and layout costs. Reviewing these points early allows you to proactively lock content, standardize files, and send clear briefs right from the start.

6. Send a comprehensive project handover package to your translation company

A smooth translation project does not just depend on the source file. In fact, the accompanying documentation is what helps the translator understand the context correctly, choose the right terminology, and reduce the number of times they have to seek clarification from the client.
The ideal documentation should include:

• Editable original files in formats such as .docx, .xlsx, .pptx, .html, or .xml.
• A PDF or reference design for comparison of the final layout if needed.
• A glossary, list of words to avoid translating, and how to spell brand names.
• A style guide or brand guide if the business already has a standard tone.
• Information about the target market, reader profile, and intended use of the document.
• Previous translations, relevant websites, or screenshots to help the translator understand the context.
• Requirements regarding output format, character limits, layout, or post-translation DTP requirements.

By simply preparing a few additional reference materials like the ones above, you can significantly reduce the risk of mistranslating terminology, using an incorrect tone, or having to revise the layout after delivery.

7. How to reduce translation costs for long-term projects

If your business frequently translates product documents, marketing materials, contracts, or training materials, the goal should not just be finding the lowest quote for each individual project. A more effective approach is to optimize the process so that the average cost gradually decreases over time.
Practical ways to reduce translation costs in the long term include:

• Standardizing the writing style of source content for clearer, more consistent, and less ambiguous sentences.
• Maintaining a common glossary for the entire marketing, product, and legal teams.
• Reusing translation memory and approved translations for recurring documents.
• Content batching instead of sending individual submissions, which reduces project management costs and avoids fees for expedited deliveries.
• Locking content before delivery to prevent mid-project scope changes.
• Prioritizing editable files and minimizing text within images.

For businesses with recurring translation needs, simply standardizing the glossary and using translation memories can make a huge difference to speed, consistency, and costs.

8. 5-minute checklist to use before sending something for translation

If you need a quick review before clicking send, please use the following checklist:

• All Track Changes have been accepted and internal comments have been removed.
• The correct editable original file has been sent, not just a PDF.
• The target language, country, or region has been clearly stated.
• Glossary, brand guide, and other important reference documents have been attached.
• The scope of work and a realistic delivery deadline have been finalized.
• Sections that do not need translation or should be kept as they are in the source document have been marked.

This short checklist is especially useful for marketing, operations, and legal teams working on multiple files simultaneously. Just a few minutes of checking before sending can save hours of editing later.

✅In Conclusion:
Preparing documents before translation not only saves costs but also ensures translation quality from the start. In important projects such as technical documents, contracts, or marketing materials, establishing a document review and standardization process is crucial.

9. FAQ

Q: How early should I start preparing my documents before a translation project?
Ideally, document preparation should begin as soon as you know a translation project is on the horizon, not after the source content is finalized. Tasks like building a glossary, defining your target audience, and converting files to editable formats can all be completed in parallel with the actual content creation. As a rule, allow two to three business days before your intended briefing date to work through the preparation checklist without rushing.

Q: Do I need a glossary if my document is short or general in nature?
For short, straightforward documents — such as a simple announcement or a general-interest blog post — a full glossary may not be necessary. However, even a brief list of brand names, product names, and do-not-translate terms is always worth providing, regardless of document length. It can take less than thirty minutes to put together and eliminates a common source of revision requests. For anything technical, legal, or medical, a glossary is strongly recommended no matter how short the document.

Q: What is the most common reason translation projects go over budget?
The most frequent cause of budget overruns in translation projects is scope changes made after work has already begun — such as adding new sections, switching target languages, or revising the source content mid-project. The second most common cause is submitting files in non-editable formats like PDFs, which require additional processing time before translation can start. Both issues are entirely preventable with proper planning upfront.

Q: Is a PDF ever suitable for submitting translations?
PDFs can be used as reference documents to maintain layout or compare final designs, but using them as the primary source file should definitely be avoided unless there really is no alternative. If PDFs are submitted as source files, the translation agency usually has to convert them to an editable format before starting, and this step can easily lead to formatting errors, missing text, or layout misalignment.

Q: What additional reference materials should I submit besides the original file?
In addition to the original file, you should submit glossaries, brand guides, relevant websites, interface screenshots, previously approved translations, and target market guidelines. These documents help the translator understand the context correctly and significantly reduce the risk of having to revise terminology or tone.

Q: Should I edit the source content after it has been submitted?
You should only edit the source content if absolutely necessary. Every change made after the project has begun can disrupt the process, affect progress, and create additional costs. It is best to lock down the source content before kicking off or, if changes have to be made, collect and consolidate them into one clear batch for the translation team to handle.
