If your average call runs 80 seconds and your service bills in full minutes, a quoted rate of $1.25 a minute is really costing you about $1.88 a call. That gap between the quoted rate and the effective one is the whole subject of this post.
Restaurant operators generally price these services by looking at the base rate and estimating their call volume. The estimate is nearly always low, for reasons that have nothing to do with dishonesty on the vendor's part and everything to do with how the billing increments work.
How the pricing is actually built
Nearly every service in this category uses the same shape. A monthly base that includes a bucket of minutes, then a per-minute rate for everything past the bucket. A common structure is something like $150 to $300 a month covering 100 to 250 minutes, with overage somewhere between $1 and $2 a minute depending on how specialized the service is.
The base is the number in the sales conversation. The overage is the number on your invoice.
What makes the overage bigger than it looks is rounding. Most services bill in full-minute or 30-second increments, rounded up. A caller who asks whether you are open and hangs up after 22 seconds is a full billable minute. A takeout order that takes 100 seconds bills as two. The arithmetic on your own log is simple enough to do in five minutes: take your call count, round each call's length up to the next whole increment, and compare that total to your raw talk time. On a mix of short questions and 80-second orders the billable total lands well above the actual one, and that difference is the part nobody quotes you.
Then there are the additions, which vary by vendor but come from a short list:
- Setup or account activation, often $50 to $150 one time, sometimes waived if you sign a longer term
- Script changes past the first one or two, charged per revision or per hour, which matters more than it sounds when your hours change seasonally
- Holiday and after-hours premiums, frequently 1.5x the standard minute rate on the days your phone rings most
- Per-message or per-dispatch fees for anything relayed to you by text or email
- Minimum commitments that bill you for unused minutes rather than rolling them forward
None of these are hidden exactly. They are in the agreement. They are just not in the quote.
What the monthly number tends to become
Work an example with numbers you can change.
Say you take 350 inbound calls a month, which is a modest volume for a takeout-heavy independent. The average handled call runs 80 seconds, so 466 minutes of actual talk time. Under full-minute rounding every one of those calls bills as two minutes, so you are paying for 700. Against a plan including 200 minutes at $200 with $1.25 overage, that is $200 plus 500 overage minutes at $1.25, which is $825 before fees.
Change the volume and the answer moves hard. A quiet 150-call month lands near $325. A December at 600 calls lands past $1,400. That variability is the complaint operators have more often than the absolute level. You cannot budget it, and it runs against you in your strongest months.
For comparison arithmetic on the other side of the ledger, our post on the real cost of a missed call works through what those same calls are worth if nobody answers at all, which is the number a service is competing against.
What you get for it, honestly
A live human answering with your restaurant's name, at any hour, who can be warm with a confused caller and who will handle something genuinely unusual without falling over. That is a real product and it should not be dismissed.
The limits are structural rather than a matter of effort. The person answering is usually working several accounts across several industries in the same shift. They have your script and your hours in front of them. They do not have your menu memorized, they cannot see whether the short ribs sold out at 7:40, and in most arrangements they are writing a message that lands in your inbox or on a printer rather than writing a ticket into your point of sale. Somebody at your restaurant still has to re-enter the order, which is a second chance to get it wrong and a task that lands during service.
Ask any service you are quoting three specific things: can the operator answer what time we close on a Sunday without asking us, can they take an order with modifiers, and does that order arrive in our POS or as an email. The answers separate a genuinely restaurant-focused service from a general call center with a restaurant script. We go through that comparison in more depth in AI receptionists versus answering services.
Reading a quote before you sign it
Five questions, and you want them answered in writing rather than on a call:
- What is the billing increment, and is it rounded up? A 6-second increment and a 60-second increment at the same rate are different products.
- Does the included-minutes bucket roll over, or do unused minutes expire?
- What is the after-hours and holiday rate, stated as a multiplier?
- What is the term, the auto-renewal date, and the notice period to cancel?
- Who owns the phone number the service answers, and what does porting it out involve?
The last one catches people. If the number on your menus, your delivery listings, and your Google profile belongs to the service rather than to you, leaving is not a cancellation, it is a migration, and you are negotiating it from the weaker side of the table.
The comparison worth actually running
Set the two options side by side on the same page, using your own numbers rather than anyone's example.
For the service: the base, plus your estimated overage with rounding added back, plus a realistic month of fees, times twelve, plus the labor cost of re-entering messages as orders. For a phone agent: the flat monthly rate, times twelve, plus setup time. Plans on this site start at $250 a month and do not move with your call volume, which is the structural difference more than the level. There is a fuller walkthrough in AI phone ordering versus answering services, and the practical mechanics of moving are in switching from an answering service.
Then look at the two annual figures and ask which one you would rather have to explain in a bad month. If your call volume is genuinely small and irregular, an answering service billed per minute may well be cheaper, and you should keep it. If your phone rings hard three nights a week, per-minute pricing is charging you most on the nights you are already the busiest, and that is worth fixing regardless of which direction you fix it in. Pull last December's invoice before you decide anything.
