Illinois restaurants run from Chicago deep-dish pizzerias to Italian beef stands to West Loop fine dining. Katalyst OS handles Chicago's stacked tax structure (state + county + city + amusement), Fair Workweek scheduling compliance, and the multi-municipality operations Chicagoland groups face.
We support restaurants, bars, food trucks, and event venues across Illinois — from Chicago to Schaumburg and every region in between.

Illinois restaurant operations are dominated by Chicago and the surrounding Chicagoland metro. Chicago itself runs everything from the deep-dish pizza tradition (Lou Malnati's, Pequod's, Giordano's defining a regional category) to the Italian beef stands that have become a national obsession, to the West Loop / Fulton Market fine dining scene that's now one of the strongest in the country. Outside Chicago, downstate Illinois runs college-town markets (Champaign-Urbana for U of Illinois, Bloomington-Normal for ISU) and the steady mid-Illinois economy.
Chicago's tax structure is one of the most layered in the country: 6.25% Illinois state sales tax + 1.25% Cook County home rule + 1.25% Chicago home rule + Chicago restaurant tax 0.5% + amusement tax 9% on dining out (the amusement tax is what makes Chicago famous for high effective restaurant taxation). Effective rate on a dine-in meal in Chicago can hit 11.25–11.5% once everything stacks. Katalyst applies and reports each layer separately for clean Illinois Department of Revenue + Chicago Department of Finance filings.
Illinois labor compliance is led by Chicago's Fair Workweek ordinance, which requires advance scheduling notice for businesses with 250+ employees in the food service, hospitality, manufacturing, and retail sectors. Tipped minimum wage in Chicago is being phased out by 2028 (currently $11.20/hr tipped + $15.80/hr non-tipped). Katalyst handles the schedule notice tracking and the Chicago-specific predictability pay rules.
Restaurant scenes, seasonal patterns, and tax regimes specific to Illinois that generic POS systems handle poorly. Here’s how Katalyst is set up for them out of the box.
Deep-dish modifier groups are some of the deepest in any restaurant category — crust type, sauce on top or under, single vs double-layer cheese, every topping in three sections. Katalyst's modifier shortcut layout handles a fully customised deep-dish in under five taps.
Chicago Restaurant Week runs twice yearly (Feb and Sept), with 400+ restaurants offering 3-course prix-fixe lunch ($25) and dinner ($39–$55). Katalyst's prix-fixe engine + reservation tools let you build the Restaurant Week menu once and toggle in/out of mode without rebuilding the normal menu.
Chicago's 9% amusement tax on dining out + 0.5% restaurant tax stack on top of state and county sales tax. Each line tracks separately on receipts and reports for clean filings with the City of Chicago Department of Finance.
Restaurant groups operating in Chicago + suburbs (Naperville, Schaumburg, Evanston, Oak Park) face different tax rates at each municipality. Katalyst applies the right rate at each address automatically, with combined-group reporting that consolidates across the corporate entity.

Yes. Katalyst applies and tracks each layer separately: 6.25% IL state sales tax + 1.25% Cook County + 1.25% Chicago home rule + 0.5% Chicago restaurant tax + 9% Chicago amusement tax on dining out. Reports break out each component for clean Illinois DOR + Chicago Department of Finance filings.
Schedule notice tracking with the 14-day advance requirement, predictability pay calculations when last-minute changes happen, and the audit trail Chicago's Office of Labor Standards Enforcement requires. Built for restaurants with 250+ employees who fall under the ordinance.
Yes. The prix-fixe engine lets you build the Restaurant Week 3-course menu once with the $25 lunch / $39–$55 dinner price points, then toggle in and out of Restaurant Week mode without rebuilding your standard menu. Reservation tools handle the surge volume that Restaurant Week always brings.
Yes. Each location applies its own tax rate (Chicago city + amusement tax differs from Cook County suburbs which differs from DuPage County), with combined-group reporting that consolidates across the corporate entity. Common Chicagoland pattern is a Chicago flagship plus 2–4 suburban locations on one Katalyst account.

POS systems aren’t one-size-fits-all. Katalyst is tuned for the kinds of operators who actually use it day to day.
Coffee shops, convenience stores, and retail of all sizes use POS systems to process payments, run loyalty programs, and update menus and pricing in real time.
From fine dining to fast food, every restaurant uses a POS system. Operators rely on POS software because it makes their day easier — taking orders, managing tables and reservations, and processing payments efficiently.
POS systems let food trucks ditch the cash register and take orders and process payments on the go. They also generate sales reports that help operators understand peak times and sales trends.
A bar POS supports order accuracy, inventory tracking, and tab management. Katalyst OS also generates detailed reports on sales and customer behaviour, helping bar owners make informed decisions.
Small and large event venues use POS systems as mobile cash registers for ticketing, food and drink sales, and merchandise.
POS systems help manage reservations and assign rooms to guests. They’re also useful for tracking food and cleaning supplies inventory and handling billing for room charges, meals, and add-on services.
POS systems support catering with everything from invoicing to inventory control, and store past clients’ information and preferences for future marketing.
Four things Katalyst handles natively that most POS systems leave you to integrate yourself.
Katalyst OS evolves and grows along with your business. Unlike rigid POS systems, our Flex POS makes integrating new features easy — open new locations and add third-party apps without waiting for your POS to catch up.
Katalyst OS gives you an inside look at customer preferences. From the moment you start using it, guest information and preferences are stored securely. Use our analytics and reporting feature to export customer details for personalised marketing campaigns and stronger guest engagement.
Our online ordering feature eliminates the middleman, saving you and your customers time and money. Guests can order takeout and large-party catering all in one place — and capture orders outside traditional operating hours.
Make sure your kitchen runs smoothly from open to close with Katalyst’s kitchen display system. By directing orders straight from customer to chef, this feature streamlines workflow while minimising errors and improving order accuracy.
“Wait… I can see what is going on without being there?”
“Katalyst is a diamond in the rough. All these companies come in and tell you what they are going to do and never do it. Katalyst sets your expectations correctly and follows through.”
“The analysis Katalyst provided me literally saved me thousands of dollars and I would have never noticed any of it unless the team at Katalyst brought it to my attention.”
A point of sale (POS) system processes payments, updates inventory, and tracks sales and customer data. When a customer places an order, an employee enters the items on the POS. The system calculates the cost and processes the payment — cash, card, or mobile. Katalyst OS automatically updates inventory by deducting items sold, keeping stock counts accurate in real time. Every transaction is recorded, so you can pull sales and trend reports as often as you like.
Katalyst OS is an example of an all-inclusive POS. We provide standard POS services such as payment processing, online ordering, and table management — and we don’t stop there. Unlike most POS systems on the market, our solution includes 24/7 support, a branded mobile app, gift card and loyalty programs, and reservations, all in one platform.
Katalyst OS handles the entire payment process end-to-end. Once a server enters the items being purchased, the POS calculates the total — applying tax and discounts automatically. Customers can tap their phone, swipe a card, or pay in cash. Once payment is approved (usually a few seconds), the POS prints a receipt or sends one to the guest’s email. Sale records and inventory levels update automatically to reflect the transaction.
