Our Pricing Philosophy 

Why is our pricing system based on word count? We firmly believe that this is the fairest and most precise way to charge for our high-quality editing services.

Charging by the page is often inaccurate and may end up overcharging you, the writer. Page counts can vary wildly because of font size, margin size, the inclusion of charts, graphs, or figures, and other formatting differences. Editors who charge by the hour have room to inflate the amount of time they may—or may not—have spent on your document.

All Sibia Proofreading clients receive the same level of detailed and thorough editing, whether they select Standard or Accelerated Delivery. Basing our prices on word count ensure that you are paying exactly what is due, and no more, and that our editors are fairly compensated for the meticulous work that they do.

Editing is a fine-tuned craft, maybe even an art, that requires more than simple knowledge of grammar rules and correct spelling. But we’ve distilled our pricing system into a science that is most cost-effective and fair for our clients.

What I expected: review of English without affecting the content, [and it] made reading my paper much easier. I’m not a native English speaker, and this is what I was looking for.
