Call centre outsourcing: when it makes sense and how to get started
Clieni Media editorial team · · 4 min read
Call centre outsourcing means an external provider handles calls, emails or chats on your behalf, following your guidelines and with contractually agreed availability. It is most useful when enquiries fluctuate, arrive outside office hours or need answering in several languages. Billing is usually per minute or based on dedicated staff, and data protection is covered by a data processing agreement under Art. 28 GDPR.
When does outsourcing customer service make sense?
Whenever your own team can no longer answer enquiries reliably without the actual work piling up. Typical situations are peaks after campaigns or during the season, calls in the evening and at weekends, a growing share of enquiries in other languages, or simply a phone that rings during appointments.
Outsourcing does not mean giving away contact with your customers. You decide what the provider answers, what gets passed on and which tone is used. Complex cases stay with you, while recurring questions, appointment scheduling or orders are handled by the external team.
- Fluctuating call volumes, for example seasonal or after promotions
- Availability outside office hours, up to 24/7
- Enquiries in several languages
- Specialists who should not be constantly interrupted by the phone
- New channels such as WhatsApp or chat that nobody internally has time for
Which billing models are there?
There are essentially two models. With per-minute billing you pay for actual talk time. This works well when volume fluctuates or is hard to predict, because costs grow with usage and drop in quiet periods.
With the FTE model (full-time equivalent), dedicated staff work for your company and are billed according to agreed working hours. This pays off with consistently high volume, products that need explaining, or when the team should be trained deeply in your systems. The agents know your customers, your processes and your special cases.
Hybrid set-ups are common: a fixed core team for the base load, per-minute billing for peaks or off-hours. Which option fits depends on volume, complexity and the availability you need, and can be reassessed after a few weeks of operation based on real figures.
What do SLAs cover in customer service?
A service level agreement sets out in measurable terms what you can expect. Typical points are availability (what share of calls is answered within what time), handling time for emails and messages, service hours and escalation paths for urgent cases.
What matters is that the values fit your business. An emergency hotline needs different commitments than order taking or an email inbox for follow-up questions. Also agree how compliance is reported and what happens if a target is missed.
How is data protection handled under GDPR?
If a provider processes your customers' personal data, a data processing agreement (DPA) under Art. 28 GDPR is mandatory. It specifies which data is processed for what purpose, which technical and organisational measures apply, who the sub-processors are and how data is deleted when the contract ends.
Make sure data is processed within the EU, access to your systems is personal and logged, and calls are only recorded with a legal basis and a notice to the caller. At Clieni Media, the DPA under Art. 28 GDPR and data processing in the EU are standard.
Which languages can outsourced customer service work in?
That depends on the provider. The Clieni Media team works exclusively in Germany and serves customers in all languages spoken in Europe. This lets you reach customers in their native language without building separate structures for each one.
Multilingual service needs aligned material in every language: call guides, answers to frequent questions and clear rules for when to hand over to a German-speaking specialist team. Call routing can be based on the dialled number or a language choice in the menu.
How does the start work?
A structured start does not take long if the preparation is right. It usually follows four steps.
- Briefing: you describe products, target groups, common requests, tone of voice and limits. Together you define what the team resolves itself and what is passed back to you.
- Call scripts: the briefing is turned into scripts and reply templates for phone, email and chat, which you approve before go-live.
- Call forwarding and systems: your existing number is forwarded fully, at set times or when busy. Access to CRM, calendar or ordering system is set up.
- Reporting: you receive regular reports on calls, request types, availability and handovers. Based on these, scripts and hours are adjusted continuously.
What should you look for when choosing a provider?
Ask concrete questions: Where is the team based? Which languages do they work in? What does the DPA look like? Which SLAs are committed and how is reporting done? Can the scope be scaled up and down? Is there a fixed contact person?
Start with a clearly defined area, such as covering calls outside office hours, and expand after the first reports. If you would like to discuss which model fits your volume, get in touch via Contact.
Frequently asked questions
What is the difference between per-minute billing and the FTE model?
With per-minute billing you pay for actual talk time, which suits fluctuating volume. With the FTE model, dedicated staff work for you during agreed hours, which suits consistently high volume or complex topics.
Do I need a data processing agreement?
Yes. As soon as a provider processes your customers' personal data, a DPA under Art. 28 GDPR is required. It covers purpose, safeguards, sub-processors and deletion.
Do I keep my phone number?
Yes. Your existing number is forwarded, fully, at set times or only when busy. Nothing changes for your customers.
