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.

Yes. Katalyst configures the 8.5% New Hampshire meals & rentals tax line correctly with no general sales tax, exactly as the NH Department of Revenue Administration expects. Hotel and B&B restaurants get rooms and meals tax tracked in the same report.
Yes. Maintain two configured menus with different items and pricing, then swap with one click between seasons. No separate setup, no IT help, no service downtime when the season changes.
Most New Hampshire restaurant suppliers connect via standard webhooks; we publish API docs and have done dozens of local supplier integrations. If your supplier has any modern data exchange, we can almost certainly connect.
Yes. Handhelds for outdoor dining, mobile order/pay for tableside checkout, and KDS routing built for high-volume kitchens. Cloud POS with offline-first transaction recording, so brief connectivity drops don’t take service down.
Most POS vendors quote a bundled processing rate and hope you don't read the statements. Send us yours — we'll show you the line-item difference Katalyst Payments would make on the same volume. No demo required first.
24-hour response · No commitment · Confidential. We work off your real merchant data, not a sales-pitch estimate.
Your last 3 months of merchant statements
Or just your effective rate and monthly volume — we'll work with what you have.
We map the same volume onto Katalyst Payments
Interchange-plus pricing, no bundled markup, no surprise tier shifts.
You see the exact monthly + annual difference
Average client saves $55K+/year. We show you the math before you commit to anything.
Feature checklists have stopped discriminating between vendors — nearly every serious platform now ships online ordering, a kitchen display, loyalty, and handhelds. What still differs is pricing structure, ownership of the stack, failure behaviour, and exit terms. Put these six to every vendor quoting you in New Hampshire, including us.
Payments are the largest recurring line in a POS relationship and the easiest to obscure. A bundled or tiered rate hides the split between interchange, card-brand assessments, and the vendor's own markup, so two quotes that look identical can differ by five figures a year.
Ask every vendor
Show me interchange, assessments, and your markup as three separate lines on a sample month of my volume.
Katalyst
Interchange-plus, with the markup stated separately. No bundled tiers and no surprise tier shifts.
Quote-gating is a negotiating position, not a technical constraint. By the time most vendors show you a rate you have spent an hour in a demo and feel invested in the outcome.
Ask every vendor
What is my effective rate on my actual volume — in writing, before I book a demo?
Katalyst
Send three months of merchant statements, or just your effective rate and monthly volume, and we return the math within 24 hours. No demo required first.
Every integration is another contract, another bill, and another support handoff on the night it breaks during service. The question is not whether a vendor offers a feature but whether they own it.
Ask every vendor
Which of these do you build, and which is a third party I would be paying and calling separately?
Katalyst
POS, payments, online ordering, kitchen display, loyalty and gift, reservations, kiosk, and a branded mobile app are all first-party on one platform.
"Works offline" covers everything from full local authorization to nothing but a cash drawer. The difference decides whether you keep serving during an outage or start writing down card numbers.
Ask every vendor
Name the transaction types that still complete offline, and tell me what happens to them when the connection returns.
Katalyst
Store-and-forward: swipe and manual key-in keep running and sync on reconnect. That is narrower than full offline authorization, and we would rather you hear it here than find out mid-outage.
The switching cost of a POS is measured in weeks of reconfiguration and staff retraining, not in the subscription. This is the number that should govern how much diligence the decision gets.
Ask every vendor
What is the term, what is the early-termination fee, who owns my sales history, and in what format can I export it?
Katalyst
Ask us those four in writing and hold us to the answers — the same way you should hold every vendor on your shortlist.
Support quality is invisible during evaluation and decisive afterwards. A tiered support plan that routes you to email during dinner service is a different product from one that does not.
Ask every vendor
Who answers during peak service, is it included, and what is the median time to a human?
Katalyst
24/7 support, included rather than sold as a tier.
Five situations where we are not the right answer, in New Hampshire or anywhere else. If one of them describes your operation, a rate analysis will confirm it faster than a demo will, and you will have lost twenty minutes instead of a quarter.
You are a single low-volume location taking card-present payments only
Below roughly $15–20K a month in card volume, a flat-rate processor's simplicity often beats an interchange-plus arrangement once platform fees are counted. Run our analysis anyway — if the math favours staying put, that is what the analysis will say.
You need full offline card authorization, not store-and-forward
If your location loses connectivity often enough that swipe and key-in fallback is not good enough, you want a system with local authorization. Ours is not that.
You are retail without a food-service operation
The platform is built around restaurant workflows — coursing, modifiers, tables, kitchen routing. General retail is better served elsewhere.
You require an on-premise deployment
Katalyst is cloud-based. Operators with a hard local-only requirement, usually for internal policy reasons, will not be able to meet it here.
You are early in a contract with a large early-termination fee
The savings have to clear the exit cost before a switch makes sense. We will tell you how many months that takes, and if the answer is more than your remaining term, we will tell you to wait.
Ranked comparisons, migration timelines, and requirements by operation type live on their own pages rather than being summarised here.
“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.”
“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.”
“Wait… I can see what is going on without being there?”
Other states we serve:
Send three months of merchant statements and we will show you the line-item difference on your own volume within 24 hours — no demo required first.
