Not every company is equally at risk. The companies most likely to be receiving inadequate service share a common profile: they're mid-size, with $100K to $2M in annual travel spend. Large enough to need real travel management, but not large enough to be a priority account at an enterprise TMC.
Enterprise providers like Navan, BCD Travel, Egencia, and American Express Global Business Travel are optimized for accounts spending $5M or more annually. Below that threshold, you're typically assigned to a shared service model — a pool of agents handling dozens of accounts, no named contact, limited customization. The technology platform may be excellent, but the human service layer is effectively absent.
This isn't a criticism of those platforms — it's the economic reality of how enterprise software is structured. A $500K account at BCD Travel represents a fraction of a percent of their business. At a boutique TMC, it's a significant, named account that gets dedicated attention.
