Third-party delivery platform commission rates (15-30%) destroy unit economics for restaurants with sub-35% gross margins

Restaurants listed on DoorDash, Uber Eats, and Grubhub pay 15-30% commission per order, but most independent restaurants operate on 3-9% net profit margins. So what? A $30 delivery order that costs the restaurant $20 in food and labor leaves $10 gross profit, but a 25% commission takes $7.50, leaving $2.50 — below the threshold needed to cover fixed costs like rent and insurance. So what? Restaurants cannot simply raise delivery menu prices high enough to compensate because platforms penalize them in search rankings and customers comparison-shop across apps. So what? Restaurant owners end up subsidizing delivery orders with dine-in profits, effectively paying to serve delivery customers at a loss. So what? This creates a death spiral where restaurants become dependent on delivery volume they cannot afford, cannibalizing their profitable dine-in traffic as consumer habits shift permanently toward delivery. So what? Independent restaurants — which employ 11 million Americans — face accelerating closure rates while platforms capture the customer relationship and data, making restaurants increasingly interchangeable commodities. This persists structurally because delivery platforms operate as an oligopoly with strong network effects (customers go where restaurants are, restaurants go where customers are), and individual restaurants lack collective bargaining power. Opting out means losing 20-40% of revenue overnight, so owners stay trapped in unprofitable arrangements.
