Comparing AI Receptionist Quotes Apples to Apples: A Pricing Worksheet

Collect three AI receptionist quotes and try to compare them. One charges per minute. One charges per call with a monthly base. One is flat rate with “fair use” language. They are priced to resist comparison, and vendors know it. This worksheet normalizes any quote to a single number: what you will actually pay per month.

Step 1: Know your numbers first

Before reading a single quote, write down your own figures. You need three:

• Calls per month. Check your phone bill or call logs for the last three months and average them.
• Average call length in minutes. Most small business calls run two to four minutes. Your phone system or carrier may report this.
• Total minutes per month: calls multiplied by average length. This is the number every per-minute quote gets measured against.

Guess conservatively on the high side. Underestimating minutes is how per-minute plans surprise you. Our guide to estimating per-minute billing walks through this calculation in detail.

Step 2: Convert every quote to monthly cost

For each vendor, fill in the same rows:

• Base monthly fee. What you pay before any usage.
• Included minutes or calls. What the base fee covers.
• Overage rate. What each extra minute or call costs beyond the included amount.
• Your estimated overage. Take your total minutes, subtract the included minutes, multiply by the overage rate. If the result is negative, your overage is zero.
• Add-on fees. After-hours premiums, per-seat charges, per-number charges, bilingual surcharges, CRM integration fees. List each one.
• Setup or onboarding fee, divided by 12. A one-time fee still counts. Spread it across the first year so it does not hide.
• Total: base fee plus overage plus add-ons plus the monthly slice of setup. That is the comparable number.

Do this for all three vendors and the fog lifts. The “cheap” per-minute plan with a low base fee often loses once your real minutes hit the overage rate. The flat-rate plan that looked expensive is frequently the cheapest at real-world volume.

Step 3: Price the fine print

Three line items hide in almost every quote:

• What counts as a billable minute. Some vendors bill from the moment the call connects, including the greeting and hold time. Some round up to the next minute. Ask for the exact definition.
• After-hours and holiday treatment. Some plans include 24/7 in the base price. Some charge a premium for nights and weekends, which is exactly when you need the service most.
• The fair-use ceiling on “unlimited” plans. Unlimited usually means unlimited within normal business use, with a threshold where the vendor can renegotiate. Ask what the threshold is and what happens when you cross it.

Our breakdown of AI receptionist pricing tiers shows what each price bracket typically includes, which helps you spot a quote that is missing standard features.

Step 4: Ask each vendor the same five questions

Send every vendor the same questions and compare the answers side by side:

• Using my numbers, X calls and Y minutes per month, what is my exact monthly bill?
• What is the most I could pay in a month if call volume doubles?
• Which features cost extra beyond this quote?
• What happens to my bill if I need to add a second number or location?
• If I cancel after three months, what do I owe?

The second question is the revealing one. A vendor whose worst case is double the quote is selling you risk. A vendor with a flat worst case is selling you predictability. Neither is automatically wrong, but you should know which you are buying.

The number that matters

After the worksheet, each vendor has one number: true monthly cost at your volume, plus a worst case. Compare those, then weigh what the numbers do not capture: booking accuracy, voice quality, and how the vendor handles the calls your business cannot afford to lose. Price decides between good options. It should not decide alone. If you want the other half of the value equation, our break-even guide shows how many missed calls it takes for the service to pay for itself.
