Take the Quiz →The Chicago payment landscape
Chicago's restaurant scene operates on high-volume, competitive margins — Michelin-recognized spots and James Beard nominees sit alongside corner taverns and neighborhood BYOBs. Interchange-plus pricing saves Chicago restaurant operators meaningfully at high monthly volumes. Logan Square, Wicker Park, and Pilsen have active independent retail and food scenes that skew toward Square and Stripe for their e-commerce integrations. The convention/catering corridor around McCormick Place runs large-ticket B2B transactions — catering contracts routinely exceed $10K — where ACH or interchange-plus billing is substantially cheaper than flat-rate card processing. Chicago's fintech and B2B software sector (based heavily in the West Loop and Fulton Market) tends to use Stripe for programmatic payment needs.

Chicago-specific considerations
Illinois sales tax complexity requires a POS with robust tax rules
Chicago merchants must charge 10.25–11.5% combined sales tax on general goods (state 6.25% + city + county + RTA), but prepared food, alcohol, and soft drinks carry different rates. A processor's POS that defaults to a flat tax rate will create systematic errors. Square, Stripe, and Helcim all support multi-tier tax tables — but you need to configure them correctly at setup. Consult the Illinois Department of Revenue's restaurant and retail guidance before you go live.
Convention and catering businesses should prioritize ACH and large-ticket invoicing
Catering groups serving McCormick Place events, corporate events at hotel venues, or private clubs in River North frequently invoice $5K–$50K per event. Card fees at 2.9% on a $25,000 event catering invoice is $725. ACH at $5–$10 is a meaningful alternative. Helcim's invoicing with ACH, Stripe Invoicing with ACH debit, or Square Invoices all support this — ensure your sales process collects ACH authorization at contract signing.

Chicago is the third-largest US metropolitan economy and home to one of the most competitive restaurant markets in the country — the James Beard Foundation has recognized more Chicago restaurants per capita than almost any other US city. McCormick Place, the largest convention center in North America, drives enormous hospitality and catering payment volume, particularly for food service, transportation, and specialty retail around the Loop and South Loop. Illinois merchants navigating processing decisions also face a uniquely complex sales tax environment: the state rate is 6.25%, but Chicago adds its own 1.25%, and some items (prepared food, alcohol) carry additional local levies — your POS and processor must handle tax tables correctly or you'll face shortfalls at reconciliation.
