New Hampshire restaurants ride a unique calendar: Lakes Region summer rushes, White Mountains ski seasons (Loon, Cannon, Bretton Woods), Portsmouth seacoast weekends, and Manchester-Nashua weekday corporate volume. Many operators run dual-season concepts — same restaurant, completely different menu, pricing, and staffing pattern in summer vs winter.
Katalyst’s POS handles per-season menu swaps without setup time, daypart-specific accelerators for the slow shoulder weeks, and the no-sales-tax-but-yes-meals-tax rules that confuse generic POS providers. Out-of-state operators expanding into New Hampshire frequently run into POS systems mis-configured for the meals & rentals tax regime; Katalyst is set up correctly out of the box.
The 8.5% New Hampshire meals & rentals tax is configured automatically, with no general sales tax line — exactly as the New Hampshire Department of Revenue Administration expects. Hotel and B&B operators running on-premise restaurants see both meals and rooms tax handled in the same Katalyst report.
Restaurant scenes, seasonal patterns, and tax regimes specific to New Hampshire that generic POS systems handle poorly. Here’s how Katalyst is set up for them out of the box.
Loon, Cannon, Bretton Woods, Waterville Valley, Wildcat — ski-restaurant operations across the Whites. Per-season menu and pricing swap, daypart accelerators tuned for après-ski windows, ski-pass partnership configurations.
Winnipesaukee, Squam, Sunapee summer-cottage and boater traffic. Counter QR ordering for walk-up summer concession volume, multi-location for a year-round main location plus a summer Lakes outpost.
Portsmouth and the seacoast pull regional weekend traffic from Massachusetts and Maine — partly for tax-free shopping. Outdoor-dining handhelds, mobile pay flows, and reservation tools built for Market Square restaurant volume.
Out-of-state operators expanding into NH commonly mis-configure tax. Katalyst is set up correctly out of the box: 8.5% meals & rentals tax line only, no general sales tax line, exactly as the NH Department of Revenue Administration expects.

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.
