The three musketeers of SaaS support: full, partial, and co-sourcing explained

Like the literary trio, different support models offer "strength in numbers" through outsourced customer support approaches tailored to various business needs.

Full outsourcing: the all-powerful but hands-off king

This approach delegates the entire support function to an external partner, similar to hiring expert mercenaries for kingdom defense.

Pros: - Cost-effectiveness: Economies of scale deliver substantial savings, particularly for smaller SaaS companies unable to build internal teams. - Expertise: Access to diverse talent pools and specialized skillsets beyond local reach. - Scalability: Support grows seamlessly alongside business expansion without internal scrambling. - Focus: Frees internal teams to concentrate on core activities like product development and marketing.

Cons: - Loss of control: Reduced direct oversight of daily customer interactions requires robust partner trust and communication. - Cultural differences: Misalignment between partner values and brand approach can compromise customer experience consistency.

Sharing the support burden: the Robin Hood of partial outsourcing

This hybrid model divides responsibilities between internal and external teams based on respective strengths.

Pros: - Retain control over core: Maintain oversight of sensitive, high-touch interactions requiring deep product knowledge. - Targeted expertise: Supplement existing teams with specific skills your partner provides, addressing capability gaps. - Flexible support model: Customize partnership scope. Outsource repetitive tickets, basic troubleshooting, or specialized technical support.

Cons: - Coordination complexity: Managing communication and collaboration between separate teams presents challenges. - Integration hurdles: Seamless data sharing between systems requires technical effort and continuous maintenance.

The synergistic shield: co-sourcing, a united front for customer support

This model unites internal and external teams in shared physical space and resources, functioning as one cohesive unit.

Pros: - Stronger collaboration: Natural knowledge sharing and cultural exchange foster unified support practices. - Direct oversight: Maintain close visibility while leveraging partner expertise and resources. - Shared costs & resources: Pool infrastructure, software, and workspace for increased efficiency.

Cons: - Cultural clashes: Merging distinct team dynamics and management styles demands careful planning and ongoing attention. - Complexity of setup: Initial configuration and sustained coordination require strong communication and collaborative commitment.


Choosing your support model depends on organizational needs and objectives. Full outsourcing emphasizes efficiency and expertise access. Partial outsourcing balances control with targeted supplementation. Co-sourcing prioritizes true partnership and unified customer experience delivery.
