In line with standard practice in the translation industry, I usually charge by volume. I can however provide a fixed-price, binding quotation for a specific text if this is preferred. For customers in the EU, prices are subject to VAT at the relevant rates.
Surcharges apply for certain text types and for certain file formats (notably PDF and PPT).
I do not offer discounts for CAT-tool usage. However, if you have a repetitive text and are willing to highlight the repeated parts (at sentence level or higher), I am prepared not to charge for them.
