Voice Call Services for the São Paulo Market
Whether you serve customers across São Paulo or sell well beyond it, voice remains one of the most inclusive channels: it works on any phone, for any literacy level, and lets customers respond with a single keypress. Below you will find how São Paulo businesses typically use voice call, the compliance points for Brazil, how we would plan the work, and what affects the cost.
São Paulo is Brazil's largest city and the financial centre of Latin America, home to the B3 stock exchange and the banks, investment firms and fintechs along Avenida Paulista and Faria Lima, including Nubank. The wider state is Brazil's industrial heartland, and the city is a major retail, e-commerce and events market.
WhatsApp is part of almost every customer interaction in Brazil, and Brazilian Portuguese content is essential, so São Paulo projects are planned around both. Whether your business operates around Avenida Paulista, Faria Lima, Vila Olímpia, Berrini and Pinheiros, or serves customers across Brazil, we shape voice call work around the way your customers search, browse and communicate.
