◆ Zay-OS vs Slice

Slice is built for pizza only. Zay-OS is built for every kitchen.

Slice has deep, real pizzeria-specific marketing and owned delivery in select markets — for a pizzeria, that is genuine value. But Slice does not work for any other cuisine, and even pizzerias still juggle separate marketplace tablets. Zay-OS works for every cuisine and pulls Uber Eats, DoorDash, and Grubhub into the same kitchen tablet via Otter.

Quick answer

Slice is a pizzeria-exclusive platform at $250-$650 per month with bundled marketing and owned delivery in select markets — strong if you are pizza-only and value the Slice marketplace. Zay-OS works for every cuisine at $499 flat per month, adds Otter ingestion of Uber Eats / DoorDash / Grubhub into one kitchen tablet, and runs the direct site on your domain instead of inside the Slice app.

Side by side

The line-by-line difference.

Slice
Zay-OS
Cuisine scope
Pizzerias only. Slice is exclusively pizza — no broader cuisine support.
Every cuisine. Mediterranean, Latin, Asian, American, halal, kosher, fine dining, ghost kitchen, food truck. Naya Grill (Mediterranean) is the live operator reference.
Monthly cost per location
$250 - $650/month per location depending on plan and add-ons.
$499 Operator / $599 Operator + Marketplace / $699 Concierge (up to 5 locations). Flat — no tier escalation by feature.
Marketing services included
Bundled marketing services — customer acquisition, paid ads, email — are a core Slice value. Strong for pizzerias specifically.
CRM + SMS + email + web push from your domain, plus Florida SEO + GEO + Google Business setup. Lower-touch than Slice marketing services, higher leverage on organic + AI search.
Marketplace ingestion (Uber Eats / DoorDash / Grubhub)
No — Slice runs its own marketplace (Slice app) and does not pull third-party marketplace orders into one tablet.
Yes, via Otter on Operator + Marketplace ($599/mo). Every channel routes to the same kitchen tablet.
POS sync (write-back)
Selected POS integrations, pizzeria-focused.
Otter-deep: 25+ POS bundled. Toast, Square, Clover, Lightspeed U, Revel, Aloha, Brink, HungerRush, Oracle Micros, Par Brink, NCR.
Owned delivery network
Yes — Slice operates its own delivery network in select markets.
Otter dispatch through 14+ courier networks (DoorDash Drive, Uber Direct, Relay, regional). Bundled into $599/mo.
Processing fees
2.9% + $0.30 standard card processing on direct orders.
2.9% + $0.30 standard card processing on direct orders. Diner pays the $2.99 per-order fee on top — restaurant keeps 100% of food revenue.
Mobile app
Slice app is the diner-facing app — branded as Slice, not as your restaurant.
PWA on your domain. Diners install your restaurant to their home screen, not a marketplace app.
Pizzerias can run both

Keep Slice for the marketplace traffic. Use Zay-OS for the direct channel.

Pizzerias do not have to choose. The Slice marketplace brings real pizza-specific diner traffic, and the Slice marketing services have measurable customer-acquisition value. Keep Slice running for that.

Zay-OS layers on top: a branded direct site on your domain so first-time Slice diners can come back without the marketplace fee, Otter ingestion of any Uber Eats / DoorDash / Grubhub presence into the same kitchen tablet, and a CRM that captures every direct diner permanently. The Slice marketplace + Zay-OS direct stack is the strongest setup we see for pizzerias that want both.

Straight answers

Slice comparison questions.

Should pizzerias pick Slice or Zay-OS?
It depends on whether you want to be inside a pizza marketplace or on your own domain. If you are a pizzeria-only operator and you value the Slice marketplace traffic + bundled marketing services + owned delivery in your market, Slice is a serious tool — they have built deep pizza-specific muscle. If you are a multi-brand operator, a pizzeria that wants to coexist with Uber Eats / DoorDash / Grubhub on one tablet, or a pizzeria that wants the diner checking out on your domain rather than the Slice app, pick Zay-OS.
My restaurant is not a pizzeria — can I still use Slice?
No — Slice is exclusively for pizzerias. If you run a Mediterranean grill, taqueria, Asian fusion concept, halal kitchen, fine-dining venue, ghost kitchen, or food truck, Slice is not built for you. Zay-OS works for any cuisine; Naya Grill (Mediterranean, Pompano Beach + West Palm Beach) is the live operator on the platform today.
Does Slice ingest Uber Eats / DoorDash / Grubhub orders?
No. Slice operates its own marketplace and dispatch network and does not pull third-party marketplace orders into one tablet. If you run Slice plus Uber Eats plus DoorDash plus Grubhub, you have four tablets. Zay-OS Operator + Marketplace uses Otter to ingest all marketplace orders into the same kitchen tablet as your direct orders.
How does the Slice marketplace traffic compare to direct ordering on Zay-OS?
The Slice app brings real pizzeria-specific diner traffic — that is the value of being in the marketplace. The trade is that the diner is a Slice user, not your customer, in the same way DoorDash diners belong to DoorDash. Zay-OS pushes diners to your domain and writes them into your CRM, so the second-and-third order does not require Slice traffic at all.
What does Zay-OS cost vs Slice for a single pizzeria?
Slice ranges $250-$650/month per location depending on plan and marketing add-ons. Zay-OS Operator is $499/month flat, Operator + Marketplace (with Otter ingestion of UE / DD / Grubhub) is $599. A pizzeria running only Slice today and adding Zay-OS lands in a similar price band but gets a branded direct site, customer CRM, and the option to ingest the big three marketplaces on one tablet.
Who pays the per-order fee on Zay-OS?
The diner pays a $2.99 per-order fee at checkout, or 10% when the subtotal is over $29.99 — whichever is greater. The restaurant keeps 100% of the food revenue. Card processing is standard 2.9% + $0.30 on the direct site, same industry rate as Slice.
