Proofreading before the mistake becomes public
A check of grammar, cohesion, terminology and fidelity to the source, by professionals who know the subject. For your own texts and for translations that came from elsewhere.
- Revisers specialised in the subject of the text
- Compared against the source when it is a translation
- Changes tracked for you to approve
What the proofreading service covers
Whoever wrote a text is too close to it to see what is missing. Proofreading by a professional is the last barrier before the material becomes public and the mistake becomes permanent.
The stakes rise in a foreign language. Errors slip past native speakers with some regularity, and the chance of missing something that undermines the text grows when it is not your first language.
A note on scope. Every translation produced by Eko’s already goes through quality control, included in the service at no extra cost. Proofreading bought separately is for text that was not translated here: material written by your team, or a translation from another supplier.
The standard service covers grammar, spelling, punctuation, cohesion, terminology and, when the text is a translation, fidelity to the source, checked sentence by sentence. You receive the file with tracked changes so you can see exactly what moved and approve it, plus a clean version.

When you need it
The reasons texts most often arrive here for revision.
Publishing without errors
The last check before the text becomes public and the mistake becomes permanent.
Submitting to a journal
Reviewers reject papers on writing quality before they assess the science.
Checking a supplier’s translation
When a translation came from outside and you need to know whether you can rely on it.
Standardising vocabulary
Unifying terms, product names and style across documents written by different people.
Meeting a standard
Adjusting the text to a regulator’s, a client’s or a style guide’s requirements.

What proofreading costs
The price depends on volume, language and, above all, on the state the text arrives in. A well written text needing a light pass is far less work than one requiring whole paragraphs to be rewritten.
That is why we assess a sample before quoting. The price is then fixed and does not change, even if the text turns out to be harder than it looked. If the assessment shows that retranslating is the better option, we say so before starting, not halfway through.
One saving that often goes unnoticed: revising the source before translating costs less than correcting the same error later, replicated in every target language.

Eko’s has been a partner for many years. Always attentive and willing to meet tight deadlines without losing the excellent quality. Having Eko’s makes a real difference in our work.
Eko’s always meets our demand and hits the deadline. They have never turned down an urgent request. They deliver quality work and are one of the very few companies qualified to work with us.
I want to congratulate Eko’s for all these years of partnership, serving us with excellence and with highly qualified, efficient professionals.
From the first contact I was well looked after, transparency at every stage and not a single problem with them, a fair price for all the work done. I do not live in Brazil and they handled every step to send my daughter’s certificate, already apostilled, here to the US.
Faster and better value than anyone else. Excellent work, service worth a ten out of ten.
I did not know them, but I decided to take a chance and have some documents translated with Eko’s. They were fast, attentive and the price was fair too. I am pleased with the service and I recommend them.
Proofreading
Why proofread a text that is already finished?
Because whoever wrote it is too close to it to see the gaps. Proofreading by a professional is the last barrier before the material becomes public, and it matters more in a foreign language, where errors slip past even native speakers.
How is this different from the quality control included in your translations?
They are different things. Every translation produced by Eko’s already goes through quality control, included at no extra cost. Proofreading sold separately is for text that was not translated here: material written by your team or translated by another supplier.
Do you proofread translations made by other companies?
Yes, and it is a frequent request. Send the translated text together with the source, because the revision compares the two sentence by sentence. If the translation has structural problems we will tell you before proceeding: sometimes retranslating is cheaper and faster than repairing.
Do you change style or only fix errors?
That is up to you. The standard service covers grammar, spelling, punctuation, cohesion, terminology and fidelity to the source. If you also want style and flow work, say so when ordering, because it changes the scope and the deadline.
How do I receive the revised text?
With tracked changes, so you can see exactly what moved and approve item by item, plus a clean version with everything applied. Comments explain the decisions that are not self-evident.
How is the price calculated?
By volume, language and the state the text arrives in. We assess a sample before quoting, and the price is fixed from that point on.
Send your document and get a closed price
A legible photo or a PDF is enough for a quote. You get the price, the deadline and guidance on apostilling within 1 business hour.
