Payment processing eats 2.5-3.5% of revenue but cash is dying

Food truck transactions average $12-$18 per order, and credit card processing fees of 2.5-3.5% per transaction ($0.30-$0.63 per sale) compound into $3,000-$7,000 annually for a truck doing $200,000/year in gross sales. Unlike restaurants that can absorb this into higher menu prices justified by ambiance and service, food trucks compete on price against both restaurants and other trucks, making it difficult to raise prices 3% without losing price-sensitive customers. Cash usage has declined to under 20% of transactions at most urban food trucks, so going cash-only is not viable — it reduces customer volume by more than the processing fee savings. Some operators try dual pricing (cash discount), but the signage requirements and customer confusion slow down service in a format where speed is everything — the average food truck lunch rush window is only 90-120 minutes, and each 15-second delay per transaction across 100+ customers costs 25 minutes of serving time. This persists because payment processors price mobile food vendors in the highest-risk merchant category (mobile, outdoor, high chargeback potential), and the average ticket size is too low for the per-transaction fixed fee component ($0.10-$0.30) to be amortized efficiently.
