Call Center Outsourcing
Definition
Call Center Outsourcing
Call center outsourcing hands inbound or outbound voice work to an external contact centre provider. It covers agents, supervision, technology, and the planning behind them, and it remains the oldest and most heavily measured form of outsourcing in the industry.
Voice is still the channel customers use when something has gone properly wrong — that is why it survives every prediction of its demise.
Pricing comes in three shapes: per hour, per seat, or per contact. Each one pushes provider behaviour in a different direction.
Per contact pricing rewards speed. Per hour pricing rewards occupancy. Neither rewards resolution unless you write resolution into the contract.
Quality slips quietly — it shows up in repeat contact rate weeks before it appears in any customer satisfaction score.
Attrition is the number that predicts everything else. A site running above 60% annual attrition will struggle to hold any quality target.
Key takeaways
- Call center outsourcing transfers voice work, supervision, technology, and planning.
- The pricing model shapes provider behaviour more than the service level does.
- Repeat contact rate is the earliest warning that quality is slipping.
- Agent attrition predicts most other performance problems at a site.
How it works
The buyer forecasts volume, agrees service levels and quality standards, then contracts a provider to staff and run the queues. The provider handles recruitment, training, workforce management, and supervision, reporting against agreed measures at agreed intervals.
Forecast accuracy is the client’s responsibility and the provider’s favourite excuse. A forecast that is 20% out makes any service level target meaningless.
| Pricing model | What it rewards | Best used when |
|---|---|---|
| Per hour | Occupancy and staffing accuracy | Volumes are unpredictable |
| Per seat | Stable capacity | Volumes are steady and known |
| Per contact | Speed of handling | Contacts are short and uniform |
| Per resolution | Getting it right first time | Quality matters more than speed |
Public service measurement has moved the same way. Performance.gov tracks High Impact Service Providers against Executive Order 14058, which directed 17 agencies to take 36 specific actions on customer experience.
External benchmarks keep internal scores honest. The American Customer Satisfaction Index is the only national cross industry measure of customer satisfaction in the United States.
Watch the calibration sessions rather than the scorecard — if client and provider quality analysts score the same call differently, the reported number means very little.
Examples
Call center outsourcing covers inbound service, outbound sales, and specialist queues, and the right pricing differs for each. Four cases show what buyers set up and what they had to correct later.
A UK retailer. Contracted 120 seats in Manila for inbound service in 2024. Per hour pricing suited the seasonal peaks better than a per seat commitment.
A US utility. Moved to per resolution pricing after two years. Average handle time rose, repeat contacts fell, and total cost dropped by roughly 8%.
An insurance client. Ran monthly calibration with the provider’s quality team. Score variance between the two sides fell from 14 points to under 4.
An Australian telco. Split outbound sales and inbound service between two providers. Sales performance improved, and the coordination overhead proved manageable.

FAQ
How much does call center outsourcing cost?
Rates vary widely by location, from a few dollars an hour offshore to onshore rates several times higher. Compare cost per resolved contact, not cost per hour.
Which pricing model is best?
Per hour when volumes are unpredictable, per seat when they are steady, and per resolution when quality matters more than speed.
What service levels should be set?
An answer time target, a quality score, and a repeat contact measure. Speed targets alone reliably produce fast, unhelpful calls.
How is quality actually controlled?
Through regular calibration between client and provider quality analysts. Without calibration, the scorecard measures agreement rather than quality.
Why does attrition matter so much?
Because every departure resets experience on the floor. Sites above 60% annual attrition rarely hold a quality target for long.
How long does transition take?
Eight to sixteen weeks for a standard queue, including recruitment and training. Complex regulated queues take considerably longer.
