Hire a virtual assistant when phone calls are a small, predictable slice of a mixed workload and what you mostly need is help with email, scheduling and data entry. Hire a call center (or answering service) when every call has to be picked up live, calls overlap or arrive after hours, or the phone is the whole job. As a rule of thumb, under about five calls a day a pay-per-use answering plan is the cheapest way to cover the phone, and past roughly ten calls a day a dedicated agent usually costs less than per-minute billing.
The rest of this guide shows the math behind that rule, using published US prices, so you can rerun it with your own call volume.
What you are actually choosing between
Most “virtual assistant vs call center” comparisons treat this as two options. In practice there are three, and they are priced differently.
- Virtual assistant (VA). One remote generalist, hired as a freelancer or through an agency, paid by the hour or on a monthly retainer. A VA answers calls alongside inbox, calendar, CRM updates and invoicing. It is one person, so it is one call at a time, during that person’s hours.
- Shared call center or answering service. A pool of receptionists answers in your company name from a script. You pay per minute or per call. They take messages, book appointments and transfer calls, often around the clock, but they do not do your admin work.
- Dedicated call center agent or team. One or more agents work only on your account, trained on your product and managed by the agency, with a supervisor, call recordings and backup when someone is out. You pay per agent per month.
Side-by-side comparison
| Factor | Virtual assistant | Shared answering service | Dedicated call center agent |
|---|---|---|---|
| Best for | Mixed admin work with a few calls | Low or spiky call volume, after-hours cover | Steady call volume that needs product knowledge |
| How you pay | Per hour or monthly retainer | Per minute or per call | Per agent per month |
| Calls at the same time | One | Several | One per agent |
| Coverage hours | The hours you buy | Often 24/7 | The shift you contract |
| Non-call tasks | Yes, that is the point | No | Call-related work: notes, callbacks, tickets |
| Who manages quality | You | The provider, lightly | The agency’s supervisor, with recordings and reports |
| Backup when someone is out | Usually none | Built in | Ask; a good agency provides it |
| Typical weak spot | Missed calls when busy or off shift | Shallow knowledge of your business; cost climbs with volume | You pay for the seat even in a slow week |
What each option costs in the US
These are published figures as of October 2026, in US dollars. Prices change, so check each source before you budget.
- US-based virtual assistant. Indeed reports an average of $22.70 an hour for virtual assistants in the United States, based on job postings (updated September 23, 2026). Freelancers and agencies set their own rates, so treat this as a wage baseline.
- In-house benchmark. The US Bureau of Labor Statistics puts the median hourly wage for receptionists at $18.27 (May 2025), and for customer service representatives at $21.53 (May 2025). Both are before payroll taxes and benefits.
- Per-minute answering service. Ruby lists 50 receptionist minutes for $250 a month, 100 for $395, 200 for $720 and 500 for $1,725, with 24/7 live answering. By our arithmetic that is $3.45 to $5.00 per included minute.
- Per-call answering service. Smith.ai lists 30 calls for $300 a month ($11.50 per extra call), 90 calls for $810 ($10.50 per extra call) and 300 calls for $2,100 ($8.50 per extra call).
- Offshore dedicated agent. For reference, Munzai’s published price for a dedicated outbound SDR is $1,800 a month for a 40-hour week, month to month, with no setup fee. Our inbound call handling, customer support and virtual assistance are quoted per scope, so read $1,800 as a reference point for a full-time offshore seat, not as an inbound price.
Worked example: three call volumes
The table below is hypothetical arithmetic, not a quote. It assumes 20 business days a month, a three-minute average call and the list prices above. A full-time month is 40 hours x 52 weeks / 12 = about 173 hours.
| Monthly cost | Light: 3 calls a day | Moderate: 8 calls a day | Heavy: 25 calls a day |
|---|---|---|---|
| Calls and minutes per month | 60 calls, 180 minutes | 160 calls, 480 minutes | 500 calls, 1,500 minutes |
| Per-minute plan (Ruby list price) | $720 (200-minute plan) | $1,725 (500-minute plan) | Above the largest listed plan; custom quote |
| Per-call plan (Smith.ai list price) | $645 ($300 + 30 extra calls) | $1,545 ($810 + 70 extra calls) | $3,800 ($2,100 + 200 extra calls) |
| US VA, 20 hours a week at $22.70 (half-day coverage) | About $1,967 | About $1,967 | About $1,967 |
| US VA, 40 hours a week at $22.70 | About $3,935 | About $3,935 | About $3,935 |
| Offshore dedicated agent, 40 hours a week (Munzai reference price) | $1,800 | $1,800 | $1,800 |
Three things stand out:
- Light volume: 60 three-minute calls is three hours of talk time in a month. A usage-priced plan at $645 to $720 covers it. A VA only makes sense if you can fill the rest of the paid hours with other work.
- Moderate volume: usage-priced plans ($1,545 to $1,725) now cost about the same as a half-time US VA or a full-time offshore seat. The break-even against the half-time VA is $1,967 / $3.45 per minute = about 570 minutes, or roughly 190 three-minute calls a month, which is nine or ten calls per business day.
- Heavy volume: the per-call plan at $3,800 is close to a full-time US VA and more than double the $1,800 offshore reference. A full-time receptionist at the BLS median would earn about $3,167 a month in wages (173.3 hours x $18.27), before taxes and benefits. A dedicated agent wins, and 25 hours of monthly talk time leaves most of the shift for callbacks and CRM notes.
The rule by call volume
- Under about 5 calls a day: use a per-minute or per-call answering service. Add a VA only if you separately have 15 to 20 hours a week of admin work to hand off.
- 5 to 10 calls a day: cost is roughly a tie. Decide with the five questions below.
- More than 10 calls a day, or more than about 600 minutes a month: pay for a dedicated person. Choose a VA if one person is enough and you will manage them yourself; choose a call center team if you need backup, a supervisor and recordings.
- At any volume: if calls overlap, come in after hours, or a missed call means a lost job, use a call center. A single VA cannot answer two calls at once.
Five questions that matter more than price
- What does a missed call cost you? If a caller who reaches voicemail simply calls the next company on the list, live answer is the requirement and price comes second.
- Do calls overlap or arrive after hours? Export the last 30 days from your phone system. Count calls by hour, and count how often two arrive within the same five minutes.
- How much non-call work is there? List the tasks and the hours. If the phone is under a quarter of the workload, you are writing a VA job description.
- How complex is the call? Taking a message or booking an appointment suits a shared service. Product questions, troubleshooting and account lookups need trained agents with access to your systems, which is customer support work.
- Who will manage quality? A VA reports to you: you write the script, listen to calls and coach. A call center should supply a supervisor, call recordings and regular reports. Ask how often the reports arrive and what is in them.
One more check: if the calls you need are outbound (lead follow-up, appointment setting, cold calls), neither option is the right hire. That is SDR work; see inbound vs outbound sales and our B2B cold calling services.
How to test before you commit
- Write a one-page call brief: greeting, the top five reasons people call, what to capture, when to transfer and what never to say.
- Ask each candidate for recordings of real calls, or have them take a live test call using your brief.
- Ask for a sample report and confirm how often you will receive it.
- Run a paid pilot of two to four weeks on the smallest plan or on month-to-month terms. Call in yourself at different times, including lunch and just before closing.
- Score it: share of calls answered live, time to answer, accuracy of messages and how often callers had to repeat themselves. Then divide the monthly cost by the calls handled.
Where Munzai fits
Munzai Solutions is an outbound sales agency that also provides inbound call handling, customer support and virtual assistance, each quoted per scope. We are a Pakistani company and say so openly: our team is in Pakistan, works US and Canadian business hours, and calls are recorded. The location is the reason for the price. At $1,800 for a 40-hour week, the dedicated SDR seat works out to about $10.38 an hour (hypothetical arithmetic: $1,800 / 173.3 hours), against the $22.70 Indeed average for a US virtual assistant. If you are weighing an offshore team, read why businesses outsource to Pakistan first.
From January to August 2026 our team logged 69,722 connected calls across all clients. We have served more than 60 clients and are rated 4.8 on DesignRush and 5.0 on Clutch. We work business hours, so if most of your calls come at night or on weekends, a 24/7 answering service may be the better fit.
