Even before the official debut of Twice, the nine members had signed contracts as exclusive models for school uniform brand Skoolooks, alongside J. Y. Park. By December 2015, Twice had signed ten CF contracts, totaling earnings of KRW1.8 billion. By February 2017, they had one of the fastest growths in the advertising industry as the group's rate charged for endorsement hit 200 million won for 6 months and 300 million won for a year.

Twice is one of the celebrity endorsers of Lotte Duty Free. They also collaborated with shoe company Spris and created their own shoe brand called "Twice by Spris". In early 2017, Twice was selected by beverage maker Donga Otsuka to promote the company's flagship sports drink Pocari Sweat on its 30th anniversary. They became the first idol group to model for the brand. Pocari Sweat recorded 100 billion won sales for the first half of the year, a 10% increase over 2016's sales.

As of 2017, Twice has represented about 30 different brands including cosmetics, clothing, online and mobile games, food and beverages, credit cards, and more. Twice's first TV commercial in Japan for Ymobile was aired nationwide starting February 2, 2018, incorporating a pop arrangement of "Y.M.C.A." and Twice's signature "TT pose". In 2019, Twice was selected as South Korean ambassador of Estée Lauder. The group also became "Global Benchsetters" for Philippine clothing brand Bench. In March 2021, Kyungnam Pharmaceuticals announced that it had selected Twice as the representatives for its flagship vitamin brand Lemona. Later that year, Nintendo Korea featured Twice playing the Nintendo Switch game Mitopia in a video. In August 2021, the group was chosen to perform for Shopee Philippines's 9.9 Super Shopping Day TV special that was held on September 9. On October 16, 2021, Scarlett Whitening, an Indonesian beauty brand known for its skin whitening products, introduced Twice as their brand ambassadors. The endorsement was, however, criticized by fans, calling JYP Entertainment to withdraw the deal as it would be "unethical" for Twice to endorse a brand with skin whitening products, "knowing that they have fans with darker skin complexions".
