The agency won the Intuit account, which is thought to be worth in the region of £300,000, following a competitive pitch. Edelman and Lewis PR are understood to have competed but incumbent Seven Hills did not repitch.
Intuit, which claims to be the largest provider of back office software to small businesses in the world with a strong presence in the US, is seeking to improve its brand awareness and market share in the UK.
