Didia Undangan provides digital website invitations designed to make celebrating special occasions quick, convenient, and affordable. Customers can browse a catalog of themes and choose an invitation for weddings, circumcisions, aqiqah celebrations, or birthdays. The catalog includes 3D Motion, Art, Interactive, Luxury, and Special designs, with options that do not require photos. Some themes reflect Indonesian cultural traditions, including Minang, Javanese, Chinese, Batak, Balinese, Bugis, and other regional styles.

Invitations can be customized with details such as the couple’s profiles, event information, guest names, and a personal theme. Features include unlimited sharing, RSVP and attendance confirmation, guest messages and prayers, background music, Google Maps navigation, photo and video galleries, prewedding content, countdowns, dress codes, love stories, and livestream links. Digital envelopes can display bank account details, and recipients can also be directed to gift information. The service advertises a one-year active period and offers customer consultation. Didia Undangan aims to help customers share their invitations broadly while bringing event details together in one accessible online experience.
