Formality and tone
Vous is the standard in French customer service, and written replies tend to be more formal than in English: a proper greeting, complete sentences and a courteous sign-off. Some brands deliberately use tu, especially with younger audiences. Whichever you choose, put it in the style guide with example replies, and check it in every quality review.
Market differences worth writing down
- Belgium and Switzerland use septante and nonante for 70 and 90, and Swiss customers usually pay in Swiss francs.
- Quebec French has its own vocabulary for everyday terms, and Quebec rules require businesses to serve consumers in French.
- Punctuation spacing differs slightly between France and Quebec; pick one convention per market and keep to it.
- Belgium, Switzerland, Luxembourg and Canada are multilingual, so French queues are often combined with Dutch, German or English.
Data protection
For customers in France, Belgium and Luxembourg, EU GDPR applies; for Switzerland, the Swiss FADP. Kosovo has no EU adequacy decision, so transfers rely on standard contractual clauses and a transfer assessment. This is general information, not legal advice; our page on GDPR and outsourcing to Kosovo goes into the details.
