Kovo vs Retell AI: Which Fits Your Restaurant?
Retell AI is voice-agent infrastructure priced by usage. Kovo is a restaurant phone line from $99. Compare the ticket, the total bill, and who maintains it.

A build demo passes every call you feed it. The agent knows the specials, reads the order back, asks about ranch. Then the kitchen runs out of brisket an hour into service and the agent keeps selling it, because nobody wrote the rule that notices.
Kovo's answer to that hour is a sold-out toggle in the menu board, carried by a daily pull that brings the POS's own availability with it. One store, one line, $99 for 750 connected minutes or $299 for 5,000, and the brisket question has an answer on the first day.
The rule that notices is what you write with Retell AI, and that is not a criticism. Retell sells voice-agent infrastructure: telephony, models, an API, priced by usage. The restaurant is the application you build on it.
TL;DR
- Kovo is $99 for 750 connected minutes or $299 for 5,000 per store, and the ticket, the reservation book, the chat channel, and the sold-out toggle arrive assembled.
- The order is read back before it is placed, and the finished ticket lands in Toast, Square, Clover, Olo, or an Epson or Star printer without anyone retyping it.
- One menu source per shop, refreshed daily, with a three-way merge that keeps an owner's edit alive and lets an 86 outrank a source still saying available.
- Retell AI is voice-agent infrastructure for developers, priced by usage, with telephony, speech, text, and voice on separate meters (vendor positioning, October 2026).
- The menu model, the POS write, the read-back, and prompt upkeep are yours to build and maintain on a platform, so a shop with no developer cannot spend the flexibility it sells.
What Kovo is
Kovo is one store, one line, one subscription. It answers the phone, takes the order in the caller's words, reads it back, and writes the ticket to Toast, Square, Clover, Olo, or an Epson or Star receipt printer. Menu questions, greetings, complaints, and order-status calls stay on the call, and handoff to a person happens when the caller presses 0, clearly asks for one, or the order is over a limit the shop chose to route, and only with a handset set.
One menu source per shop, either a POS catalog or a menu page the listing gave us: Toast, DoorDash, Uber Eats, Clover, Slice, or a pasted link. Refresh runs once a day in the background, and the merge is three-way with tombstones: your edit to a field survives a source refresh, an 86 outranks a source still saying available, and an item you deleted is not resurrected.
Starter is $99 for 750 connected minutes, roughly 300 calls at a two-and-a-half-minute average; Unlimited is $299 for 5,000, and at the cap the phone forwards to the shop's own line. The rest of the line is assembled on the same subscription: the same engine answers a website chat, books a table in Kovo's own reservation book one seat per slot, and charges a card the shop already holds, off-session, while the caller is on the line. A first-time caller gets a Stripe Checkout link with the line held open, and paying vaults the card for next time. No card number is spoken to the agent, and nothing is written into OpenTable or Resy, whose pages get read out and texted instead.
What Retell AI sells, and what you supply
Retell AI is one of the voice-agent platforms, in a group with Vapi and Bland, aimed at people who write code. Its public site sells the building blocks: models to choose, an API to call, telephony to attach, usage-billed. Flexibility, model choice, and API control are real things a packaged restaurant product does not hand over.
The buyer that shape fits is a group with engineers who want to own the stack. What arrives with that ownership is what quotes leave out: the menu model, the order-to-POS path, and prompt upkeep stay in your backlog, and the platform bills telephony, speech, text, and voice on separate meters (vendor positioning, October 2026).
The 30-second facts
Published positioning, October 2026. Where a vendor has documented nothing, the cell says so, because that blank is a build item.
| Kovo | Retell AI | |
|---|---|---|
| Starting price | $99/mo for 750 connected minutes; $299 for 5,000 | Usage-based; telephony, speech, text, and voice billed separately |
| What the call ends with | Order read back, then ticketed to the kitchen | What your code does next |
| Where the ticket lands | Toast, Square, Clover, Olo, Epson Server Direct Print, Star CloudPRNT | Not shipped; you write the POS path |
| Card handling | A card the shop already holds, charged on the line; link for a first-time caller | Not shipped; you assemble it from providers |
| Reservations | Kovo's own book; reads and texts an OpenTable or Resy page | Not shipped; you build it or integrate one |
| Website chat | Yes, same engine, embeddable | Not shipped; you add the channel |
| Who maintains it | The subscription | Your developer |
| Buying shape | Self-serve signup, one store per subscription | A build; confirm the launch date with whoever writes it |
Two rows decide most of these deals and neither is price. "What the call ends with" and "who maintains it" change what your staff does on a Wednesday, and only one of them shows up on a page like this one.
Who owns the second week
Launch day is the easy day on any voice agent. The calls are chosen, the menu is clean, and someone is watching the transcript. The second week is when a shop finds out what it bought, so walk through the three failures that surface then.
The menu changes. A new size, a price rise, two items off for the season. On Kovo the source refreshes and callers hear the new version the next day; the menu sync mechanics explain the merge. On a platform you ship the change to your own menu model and test the read-back, and there is no refresh unless you wrote one.
The order is read back wrong. The read-back is the single behavior that stops wrong orders, and on a platform it is a prompt rule you maintain across model swaps. Kovo does this on every order, and the Toast walkthrough shows what reaches the kitchen once it does.
The kitchen runs out. An 86 during the dinner rush is where the two shapes separate hardest. On Kovo it is a toggle in the menu board, Square's sold_out and Clover's available survive the pull, and an owner's 86 outranks a source that still says available. On a platform it is an event you subscribe to, a write you build, and a merge rule you maintain.
The money, in your numbers
Write the usage side out at your own volume first. A shop answering 600 calls a month at three minutes is 1,800 connected minutes.
- 1,800 telephony minutes, billed by the platform.
- 1,800 minutes of speech to text.
- Tokens for every turn, including each read-back.
- Characters synthesized for every word the caller hears.
- Your engineering time for the menu model, the POS path, the prompt, and the monitoring.
Four meters and one salary line, and only one of the five has a number you can budget. On Kovo those same 1,800 minutes are Unlimited at $299, which covers 5,000 minutes, and the plans page shows the minute arithmetic behind that.
Then price the thing the subscription is meant to fix. A QSR Magazine analysis estimates the average restaurant misses about 150 calls a month, and industry estimates put a lost call at $35 to $85. At 150 × $35 that is $5,250 a month, four times the Kovo plan, and that is what makes the choice consequential.
The decision, by situation
Three buyers, three answers. One row is not ours.
| Your situation | Pick | Why |
|---|---|---|
| One or two shops, a POS already in place, calls are orders and hours, nobody on staff writes code | Kovo | $99 or $299 a month, self-serve, ticket in the POS, menu imported rather than modelled, and the book, chat, and card handle are already there |
| A group with engineers that wants the conversation logic, the model choice, and the call data inside its own stack | Retell AI | Model choice and API control are the reasons to own the stack, and no packaged product hands them over |
| A software team building a restaurant ordering product that needs a phone channel | Retell AI | The voice layer is the part worth renting; the menu and the ticket are the part worth owning |
A group already running its own ordering system has a good reason to keep the phone inside it, and that group is who Retell sells to.
FAQ
Is Retell AI built for restaurants?
No. Retell AI is voice-agent infrastructure sold to developers: telephony, models, and an API you assemble an agent on, billed by usage. Restaurant behaviour, which means nested modifier groups, a read-back, and a write into Toast or Square, is what you build on top of it. Kovo sells that behaviour packaged for one store at $99 or $299 a month.
What is the real monthly cost of a Retell AI agent at 900 calls?
There is no published all-in number, because four meters run at once: telephony per minute, speech to text per minute, the text model per token, and the voice per character. At three minutes a call, 900 calls is 900 minutes on each meter plus your engineering time. Kovo is one figure for the same month: $299 covers 5,000 connected minutes, which is about 1,600 calls at that length.
Who keeps the agent working when the menu changes?
On Retell AI, you do. The menu model, the prompt, and the write path are your code, so a new size or a price change is a change you ship and test, and the refresh happens only if you wrote one. On Kovo the menu imports from one source and refreshes once a day, an owner's edit to a field survives the source refresh, and sold out is a toggle in the menu board that outranks a source still saying available, so the Wednesday change is a menu edit rather than a release.
Can Kovo take a card or book a table?
Yes to both, with a shape worth knowing. Kovo books tables in its own reservation book and writes nothing into OpenTable or Resy. On payment there are three paths: pay at the counter, a card the shop already holds charged while the caller is on the line, or a Stripe link texted to a first-time caller with the line held open. No card number is spoken to the agent, and the order limits belong to the shop, defaulting to 10 items and 8 of one item.
Which is faster to launch, Retell AI or Kovo?
Kovo is a signup, a menu source, and a test call, which most shops with a supported POS finish in a day on a 14-day trial that needs no card. Retell AI launches when your integration ships and passes a modifier test, so the date belongs to your developer. Ask for that date in writing, with the POS write and the read-back included in the scope.
Final Thoughts
Retell AI and Kovo answer the same ring from opposite ends. Retell hands you the parts and the bill for each one. Kovo hands you one assembled line for one store and a ticket in the kitchen. One of them is the better product for the person who would be maintaining it.
Count the people first. If a developer you employ owns the menu model today, the platform is the honest buy. If the answer is nobody, the $99 plan costs less than one of their afternoons.
Retell's month is a build plus four meters. Kovo's is one number, and the menu imports in a day. The comparison hub has the rest of the shortlist, and Kovo vs Vapi argues the build-it-yourself case from the other side. Run your own specials, your own 86, and your own large order past whichever one you are considering before the contract, not after. Take a test call with your own menu.
