For most of thirteen years I owned content and moderation for three markets: Brazil, Angola and Mozambique. On an org chart that is one line — Portuguese. In practice it is three countries, three regulatory contexts, and three sets of assumptions about what is normal.
The shortcut is understandable. One language, so you staff one team, write one policy, translate one set of help articles and move on. It works right up until it doesn't, and when it fails it fails in the places you are least equipped to see.
Language is not market
The differences that matter are rarely vocabulary. A help article written in São Paulo idiom reads as slightly foreign in Luanda — understandable, but written for someone else, which is a feeling users notice before they can name it. Payment methods differ. Connectivity differs, and a flow that assumes a stable connection produces a completely different category of complaint where the connection drops halfway. What counts as an acceptable joke differs. What counts as a serious threat differs.
What we standardised, and what we deliberately did not
Standard across all three: the policy itself, the escalation path, and the brand voice at the level of register — how formal we are, how much we apologise, whether we use humour at all.
Local by default: examples, cultural references, campaign timing, and the channels people actually use to reach us. A marketing beat built around the Brazilian school calendar means nothing in Mozambique. A campaign built around a football fixture might mean everything in all three, but not on the same dates.
The cost of getting it wrong is invisible
This is what makes the mistake so easy to keep making. A user in Maputo who finds the help centre useless does not file a complaint about the help centre. They stop using the product. The number that eventually moves is retention, three months later, and nobody traces it back to a paragraph written by someone who had never spoken to anyone there.
What I would tell a company entering these markets
Ask who on the team is actually from the market, not just who speaks the language. A native speaker of Brazilian Portuguese is not a proxy for an Angolan user, any more than someone from Texas is a proxy for someone from Glasgow. And when that person tells you a phrase does not work, the correct response is to change the phrase — not to ask them to justify it in English.
