Outsourcing customer service can cost anywhere from $0.50 per minute to $65 per hour, depending on where the agents sit, how complex the work is, and which pricing model you sign. But the more important question is whether outsourcing is actually cheaper than building in-house, and for many teams, it is not. This call center outsourcing cost comparison breaks down the real numbers, the pricing models, the fees that never show up on the first quote, and how to know which model wins for your team size.
TL;DR:
Pricing depends mostly on agent location and the model you choose. The table below compares the main options side by side so you can see the trade-off between cost and control before you commit.
The average cost of outsourcing customer service depends on how the vendor bills you. Five common models:
Inbound and outbound are different jobs, so outsource call center pricing differs too.
Inbound work is customer support, order handling, and help desk. It is reactive, often billed per minute ($0.50–$1.75) or per hour, and rewards agents who resolve fast and keep customers calm.
Outbound work is sales, surveys, collections, and lead generation. It is proactive, usually billed per hour ($10–$50), and needs agents trained to pitch, qualify, and handle objections. Because that skill set is harder to staff and manage remotely, outbound often carries performance incentives on top of the hourly rate — which makes quality control harder to enforce.
Two vendors can quote very different numbers for the same headcount. The outsource customer service cost moves with:
The quoted rate is the start of the conversation, not the end. Industry data shows hidden costs add 15–25% on top of the headline number. Budget specifically for:
Add these up and a "cheap" offshore quote at $8/hour can land much closer to a nearshore number once the full cost stack is visible.
Most outsourcing comparisons only show the hourly rate. Here is what a 20-agent US-based in-house operation actually costs per year, line by line:
Total annual cost: roughly $1,059,000–$1,602,000 — or about $4,400–$6,700 per agent per month fully loaded.
A nearshore outsourced team of 20 dedicated agents runs roughly $300,000–$720,000 per year ($1,250–$3,000 per agent per month). That is real savings — but notice that cloud contact center software represents only $6,000–$12,000 of the in-house total. The software is not what makes in-house expensive. Salaries and facilities are.
If you already have the agents and just need the phone system, cloud software at $25–$50 per seat per month makes in-house fully competitive with nearshore outsourcing.
There is no universal right answer — the model that wins depends on your team size, call complexity, and how much the customer conversation is worth to your business.
Answer these five questions. Three or more answers in the same direction gives you a clear signal.
If three or more answers point toward in-house, the next question is simply: what is the cheapest way to run an in-house team? Cloud contact center software is almost always the answer.
Outsourcing earns its keep when:
Keep it in-house when you have:
If the comparison points you toward keeping support in-house, you do not need a server room or a six-week rollout to do it. PBX.IM is a cloud phone system sold per seat, typically $25–$50 per agent per month, so you scale by adding people, not by buying minutes or hardware.
Each seat includes extensions, routing, voicemail, and AI call transcription. Teams already on Microsoft Teams can turn it into a full inbound and outbound phone system with Direct Routing — no rip-and-replace, no hardware, operational in minutes. WhatsApp business messaging plus CRM and helpdesk sync (HubSpot, Salesforce, Zendesk, Freshdesk) keep every conversation in one place. For higher-volume sales and support floors, the premium contact center tier adds live call monitoring (listen, whisper, barge), recording, IVR, skills-based routing, and analytics.
For multinational and multi-office teams, PBX.IM adds one more advantage outsourcing can rarely match: local numbers across 155+ countries on a single account. Instead of managing separate BPO contracts per region, your whole team runs on one platform with one bill — the phone system that scales with you.
Pricing is per seat with no hidden fees, none of the setup-fee-and-overage surprises that inflate outsourcing invoices. See per-seat pricing to size it for your own team.
Most call center outsourcing runs $0.50–$1.75 per minute for inbound, $10–$50 per hour for outbound, or $1,200–$4,000 per month for a dedicated agent. Location and complexity drive the spread.
By location, expect roughly $5–$16 per hour offshore, $12–$30 nearshore, and $28–$65 onshore. The model (per hour, per minute, per ticket, or retainer) shifts the effective rate significantly.
Not always. Offshore outsourcing looks cheaper on the sticker price, but hidden fees, rework, and lost brand control close the gap. For a 20-agent team, in-house with cloud contact center software ($25–$50 per seat per month) often lands between offshore and nearshore total cost — while keeping full control of your brand and customer data.
Most BPO providers set minimums around 5–10 dedicated agents. Below that threshold, the setup fees, training costs, and management overhead typically make cloud contact center software a better deal — you get the same routing, queuing, and analytics without outsourcing minimums.
Yes. Many businesses run a hybrid model: an in-house team handles core hours and complex calls, while an outsourced partner covers overflow, after-hours, or seasonal spikes. Cloud contact center software with call routing rules makes it straightforward to split volume between the two without separate systems.
Budget for setup fees ($2,000–$20,000 one-time), training costs during ramp, minimum monthly usage commitments, overage charges above contracted volume, QA and reporting add-ons ($500–$2,500 per month), CRM integration fees ($2,000–$15,000), and account management fees. These typically add 15–25% on top of the quoted hourly rate.
Teams Direct Routing turns your existing Microsoft Teams environment into a full inbound and outbound phone system with real PSTN calling — no rip-and-replace, no new hardware. You add per-seat calling on top of Teams you already run, which makes in-house far cheaper than many teams assume. This is one of the most common reasons businesses choose cloud contact center software over outsourcing.
Yes. Cloud contact center software like PBX.IM runs per seat with no hardware — typically $25–$50 per agent per month. For a 20-agent team that is $500–$1,000 per month for the software, far less than outsourcing minimums, and you keep full control of your brand, data, and customer relationships.
