Built for how events actually run here
Most event software assumes reliable internet, card payments, and guests who will happily create an account. Weddings, conferences and memorials in Tanzania run differently, invitations travel on WhatsApp, payment is mobile money, and the venue's network gives out exactly when the queue at the gate is longest.
KadiChap is built around those facts rather than despite them. Invitations go out over WhatsApp and SMS. Guests RSVP from a link without signing up for anything. Check-in keeps working with no signal at all and reconciles itself afterwards. Billing is in shillings.
KadiChap is part of the Upesi family of products, alongside UpesiNet and UpesiLipa.
