California is the most diverse restaurant market in the country — from Koreatown LA to Mission burritos in San Francisco to wine-country tasting rooms in Napa. Katalyst OS powers operations in every market the state runs, with the tax, labor, and multi-location handling California operators actually need.
We support restaurants, bars, food trucks, and event venues across California — from Los Angeles to Berkeley and every region in between.

California is the most operationally varied restaurant state in the country. LA alone runs Koreatown BBQ, Boyle Heights taquerias, Beverly Hills fine dining, and the country's densest food-truck scene — each with different POS demands. The Bay Area layers in tech-worker volume and ghost-kitchen / delivery saturation that Uber Eats and DoorDash drove past 50% of revenue for many operators. San Diego, Sacramento, and the Central Valley each have their own patterns, and that's before wine country tasting rooms even come into play.
Katalyst's tax engine handles California's compound sales tax automatically: 7.25% state plus the local district taxes that push total to 7.75% in most of LA County, 8.625% in San Francisco, 9.25% in Long Beach, and up to 10.75% in cities like Pico Rivera. Hot prepared food and dine-in are typically taxed; cold to-go food is often exempt — Katalyst tracks the distinction at the menu-item level so the receipts and reports stay clean.
California labor compliance is where most out-of-state POS systems fall short. Katalyst integrates mandatory meal and rest break tracking, the 80%-advance scheduling notice required by Fair Workweek ordinances in San Francisco, Berkeley, Emeryville, and LA, and the paid sick leave accrual rules that took effect statewide in 2024. Tip pooling is handled per CA Labor Code 351 — no manager or supervisor in the pool, no exceptions.
Restaurant scenes, seasonal patterns, and tax regimes specific to California that generic POS systems handle poorly. Here’s how Katalyst is set up for them out of the box.
Koreatown BBQ, Boyle Heights taquerias, Westside fine dining, Sawtelle Japanese, food trucks everywhere. One Katalyst account handles modifier complexity, multi-language receipts, and revenue-centre reporting across however many concepts your group runs.
Many SF and Oakland operators see 40–60% of revenue through Uber Eats, DoorDash, and Grubhub. Katalyst's native integrations pull marketplace orders straight into the KDS — no separate tablet stack on the wall.
Napa and Sonoma tasting rooms commonly run retail wine sales + tasting room service + restaurant + private events on one operation. Katalyst handles the retail/restaurant duality with shared inventory, per-channel pricing, and combined customer profiles.
Mandatory meal-break tracking, 80%-advance scheduling notice (SF, Berkeley, Emeryville, LA), and statewide paid sick leave accrual — all integrated. Avoid the lawsuit class actions that have hit operators using non-compliant scheduling tools.

Yes. Katalyst applies the 7.25% California state sales tax plus all applicable local district taxes automatically, with rates updated per city and county. Hot prepared food and dine-in lines are tracked separately from cold to-go (often exempt). Multi-location operators see the right rate at each address with no manual configuration.
Katalyst tracks meal and rest breaks at the staff-clock-in level, prompts breaks at the required times, and surfaces missed breaks for owner review at end-of-shift. The audit trail satisfies CA Labor Code 226.7 enforcement requirements and protects you from the class-action exposure most CA operators face.
Yes. Multi-revenue-centre is built in: retail wine sales, tasting room service, restaurant dining, and private events all run as separate revenue centres on one Katalyst account. Shared inventory, shared customer profiles, separate reporting where you need it.
Yes. The scheduling module handles the 80%-advance notice required by SF, Berkeley, Emeryville, and LA Fair Workweek ordinances, with predictability-pay tracking when last-minute changes happen. Compliance reports satisfy local labor office requirements.
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 California, 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 California 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?”
