Most small restaurants spend $0 to $60 a month on AI: one chat assistant plus the AI already built into their POS and office software. An AI phone line takes the total to roughly $100 to $450. Phone ordering, several paid seats and automation push it past $600. The phone line is usually the biggest cost.
The subscriptions are the smaller part of the real cost. Someone has to set tools up, keep menus and hours current, and check what AI sends to guests, and in a small restaurant that time often costs as much as the software. Here is every place AI appears on a restaurant's bills, three realistic set-ups priced line by line, and the hidden hours to add to them.
The four places AI shows up on a restaurant's bills
- A general assistant for the owner and managers: menu descriptions, review replies, supplier emails, job adverts, rota messages. One paid seat covers most small restaurants.
- AI inside the systems you run on: your POS, your office suite, your booking platform. This is often included at no extra cost, and it's the most under-used line on the list.
- Dedicated AI tools: phone answering is the main one; review management and marketing tools are the others restaurants commonly buy.
- Glue: an automation tool such as Zapier or Make that moves data between the others, for example sending every new booking enquiry into a shared sheet.
Budget in that order. Each line down the list costs more and needs more upkeep, so only move to the next when the one above is fully used.
Line-by-line prices, September 2026
List prices in USD from the vendors' pages. Promotional prices, currency and local taxes will change what you actually pay, so confirm on each pricing page before you commit.
| Item | List price | Notes |
|---|---|---|
| ChatGPT Plus | $20/month | One person. Consumer plan: switch off model training in privacy settings |
| Claude Pro | $20/month, or $17/month billed annually | One person. Same privacy point as above |
| ChatGPT Business | $25/user/month monthly, $20 annually | Minimum 2 seats. Business data not used for training by default |
| Google Workspace Business Starter | About $7/user/month on an annual plan | Includes Gemini in Gmail and the Gemini app |
| Microsoft 365 Business Basic or Standard | $7 or $14/user/month, annual | Copilot Chat included at no extra cost. Both prices rose on 1 July 2026 at next renewal |
| Toast IQ | No additional cost | Toast says its AI assistant is included with Toast POS: questions about sales, labour and menu performance, plus actions with your confirmation |
| AI phone answering | About $85 to $599/month per location | Answering only at the low end; bookings, orders and payments cost more |
| Zapier | Free; Professional $19.99/month annual, $29.99 monthly | Professional includes 750 tasks; each successful action step is one task |
| Make | Free up to 1,000 credits; paid from about $9/month | Credits-based |
| Scheduling with sales forecasting | Varies by tier and location | Forecasting and auto-scheduling usually sit on upper tiers; check which tier includes them |
Two things stand out. The AI you may already own (in Toast, Workspace or Microsoft 365) costs nothing extra, and the phone line costs more than everything else combined. The full costs and payback of AI phone answering are worth reading before you add that line.
Three restaurant budgets
These are illustrations with round numbers, not recommendations for any one vendor.
An owner-run café-bistro, 30 seats
The owner uses one assistant for menu copy, review replies and supplier emails. The POS already includes an AI assistant for sales questions. The owner's existing office suite is enough, with no add-ons. Online bookings go through the existing platform.
Monthly AI cost: $20. About $240 a year. The limit here is the owner's time, not the budget.
The first budget decision usually arrives when the café's head chef wants a seat too. Two routes cost almost the same. A second individual plan brings the total to $40 a month. ChatGPT Business needs at least two seats, so it's $50 billed monthly or $40 billed annually, and for that price business data isn't used for training by default and the two of them can share projects, such as one holding the menu, allergen matrix and supplier list. Paying annually for Business costs no more than two personal plans, so once staff are typing supplier prices and rota details into it, the business plan is the sensible default. Billed monthly, the privacy default costs $10 a month extra.
A neighbourhood restaurant, 60 covers
The owner and the general manager both write every day, so they share a business plan for data protection reasons. Missed calls in service peaks justify an answering-only phone line. A small automation logs phone enquiries and large-party requests to a shared sheet.
- ChatGPT Business, 2 seats billed monthly: $50
- AI phone answering, answering only, billed yearly: $85
- Zapier Professional, billed annually: $19.99
Monthly AI cost: about $155. About $1,860 a year.
A 90-cover restaurant with busy takeaway
Three managers use the assistant. The phone line takes bookings and takeaway orders straight into the POS, which needs the higher tier. Automations send orders and enquiries to the right people.
- ChatGPT Business, 3 seats billed monthly: $75
- AI phone answering with bookings and orders: $350 to $399
- Zapier Professional, billed monthly: $29.99
Monthly AI cost: about $455 to $505, rising past $600 with a premium phone tier. About $5,500 to $6,100 a year before any premium features.
Before copying any of these, check that every seat is earning its keep. Not everyone on your team needs a paid licence; who actually needs a paid AI licence helps you decide seat by seat.
Which line pays for which restaurant job
Owners often buy a tool for a job the cheapest line could already do. Match each job to the least expensive line that handles it well, and pay more only when the condition in the last column is true.
| Job | Cheapest line that does it | Pay for more when |
|---|---|---|
| Menu descriptions, specials boards, event copy | The assistant | Rarely; this is drafting, and a $20 seat does it |
| Replying to online reviews | The assistant, with a saved prompt in your voice | You run several sites and need one place to see every review |
| Supplier emails and order checks | The assistant, plus sales figures from your POS | Stock and ordering already run through software with AI suggestions |
| Sales questions: best sellers, slow nights, labour against sales | AI inside your POS, if it has it | Your POS has no AI and you're exporting spreadsheets every week |
| Rota building and labour forecasting | Your scheduling app's forecasting tier | Labour is your biggest controllable cost and rotas take hours each week |
| Phone questions about hours, parking, menus | An answering-only phone line | Your missed-call count shows many booking attempts |
| Phone bookings and takeaway orders | The booking and ordering tier of a phone line | The recovered covers and orders clearly exceed the higher price |
| Allergen and dietary questions | No AI line. A trained person who checks with the kitchen | Never; route these to staff whatever you buy |
Review replies show how far the cheapest line goes. A saved prompt in the assistant, used by an illustrative 45-cover gastropub, looks like this:
Write a reply to this review for our pub's Google profile.
Our voice: warm, plain, no exclamation marks, signed "Sam, GM".
Thank them for something specific they mentioned.
If they raise a problem, acknowledge it in one sentence and
say what we're doing about it. Never offer refunds, vouchers
or free items in a public reply. Under 80 words.
Review: "Sunday roast was superb, best roast potatoes we've had.
Waited 40 minutes for mains though, and nobody told us why."A typical first draft (illustrative):
Thank you for coming in for Sunday lunch and for the kind
words about our roast potatoes. We're sorry about the 40-minute
wait for mains; that's longer than it should be. Please get
in touch and we'll happily treat you to dessert next time.
Sam, GMAlmost right, and the slip is the useful lesson: despite the instruction, it offered a free dessert, which in public invites every future reviewer to mention a wait. Delete that line and replace it with what's actually changing ("we've added a second person on the carvery at Sunday lunch"). The whole job takes two minutes on a $20 seat, which is why a dedicated review tool only earns its price for groups with several sites to watch.
Sales questions are the other job a cheap line often covers, if your POS has an assistant. An illustrative pizzeria owner types: "Which five dinner items sold fewest on Monday to Thursday in August, and what did each make?" The answer comes back as a ranked list, with a garlic-bread starter and a vegan pizza near the bottom. Before cutting either, check one thing: the vegan pizza was renamed halfway through the month when its topping changed, so the POS counts it as two items, each looking weak, and together it sits mid-table. Ask the same question with "treat items with similar names as one" or look at the item list for duplicates. That check takes two minutes and is the difference between a useful answer and a menu change based on a data quirk.
Run down this list before any renewal. If a paid tool is doing a job the line above it could handle, it's a candidate to cancel, and if a job has no line at all, that is where the next slice of budget should go.
The hours that never appear on an invoice
Price your own time and your managers' time, because it's real money even though nobody sends a bill for it.
| Hidden cost | When | Typical time |
|---|---|---|
| Setting up each tool: accounts, settings, first prompts, testing | One-off | 2 to 8 hours per tool |
| Writing the phone line's knowledge: menu, hours, policies, what goes to a person | One-off | 4 to 8 hours |
| Keeping menus, specials and hours current in every AI tool | Weekly | 20 to 40 minutes |
| Checking AI drafts before they go to guests: review replies, emails, posts | Daily | 5 to 15 minutes |
| Showing staff what the tools do and what they must never do | Per new starter | About an hour |
For the 60-cover example, that could be around 12 hours of setup (about $300 at $25 an hour) and 90 minutes a week of upkeep, about $1,950 over a year. That's more than the subscriptions. It doesn't mean AI is a bad deal, because the same tools should save more hours than they take; it means the budget should show both columns. Where the savings actually come from is covered in where AI actually saves time in a small restaurant.
Skip the upkeep line and the cost shows up somewhere else. Picture a restaurant that drops its Sunday roast for the summer and updates the printed menu, the website and the Google profile, but not the phone line's knowledge base. For three Sundays the assistant tells callers the roast is on. Four tables arrive expecting it, one leaves, and a review mentions "a phone line that doesn't know the menu". The update would have taken five minutes. A fixed slot works better than good intentions: Monday afternoon, 20 minutes, one list of every place the menu lives (printed menu, website, booking platform, phone line, delivery apps, the assistant's saved project), each ticked off when the week's changes are in.
How the bill changes between month one and month twelve
- Trials and promotions end. A first-month price or an introductory discount can make month one look cheap. Budget at the full list price.
- Seats creep. One manager gets a seat, then the sous chef asks, then the new assistant manager. Each is $20 to $25 a month.
- Usage grows. Automation tasks rise as you add steps, and phone plans with caller caps charge per extra caller in a busy month.
- Prices rise at renewal. Microsoft 365 Business Basic went from $6 to $7 and Business Standard from $12.50 to $14 per user per month from 1 July 2026, applied at each customer's next renewal. Expect similar moves elsewhere.
- Annual billing cuts the rate but locks you in. Commit only after a tool has proved itself for a couple of months.
For the 90-cover restaurant above, a realistic drift looks like this. In month one it pays $75 for three assistant seats, $350 for the phone line and $29.99 for Zapier: about $455. By month twelve the head chef and the events coordinator have seats too ($125 for five), the phone line has moved to Slang.ai's Core tier at $399 for a SevenRooms connection, and takeaway orders now run through two automation steps each, so roughly 900 tasks a month have pushed Zapier from Professional's 750 up to the Team plan at $103.50 billed monthly. The bill is now about $628 a month, nearly 40% higher, and none of the three decisions felt large on the day it was made. A quarterly look at the bill catches this while each change is still easy to question.
Where to cut without losing the useful part
- Use the AI built into your existing systems first. Check your POS, office suite and booking platform for AI features before buying anything new.
- Keep one assistant. Two chat subscriptions doing the same drafting is the most common waste in small businesses.
- Buy the phone tier your calls need. If takeaway orders come through an app or website, don't pay for phone ordering.
- Review every subscription quarterly. A 20-minute check catches unused seats and duplicate tools; auditing your AI subscriptions gives you the method.
- Cancel on evidence. If a tool hasn't changed a number you track after 90 days, stop paying for it.
A first quarterly check often pays for itself on the spot. In an illustrative 50-cover bistro, the card statement showed ChatGPT Plus on the owner's card and Claude Pro on the manager's, both used for the same menu copy and review replies, plus a Zapier Professional plan whose only Zap had been switched off since spring. Keeping one assistant and dropping Zapier back to the free plan saved $20 and $29.99 a month, about $600 a year, with nothing the team actually used lost. Card statements are the place to look, because subscriptions bought by different people don't all reach the same inbox.
