The real cost of an uneven translation
Many brands and agencies split their French content between several freelancers, or between a machine translation and a quick proofread. Each text may be correct on its own. Put them side by side, and the terminology drifts, the tone changes from page to page, and your French readers no longer recognise the brand they know in English.
Fixing this later costs more than getting it right once. A translator who knows your field, maintains a glossary and uses the right tools keeps every text consistent, and saves your team the back-and-forth.
