The Anatomy of Week-Of Wedding Friction

Nearly every wedding budget reaches 100% allocation three months before the wedding day. Then, during the final 7 days leading up to the ceremony, a cluster of small mandatory friction expenses strikes.

Without a dedicated 5% liquid emergency buffer, couples are forced to charge these surprise fees onto high-interest credit cards at the finish line.
