# Best Outsourced Sales Companies - Page 9

*By [Julie Jung](https://research.g2.com/insights/author/julie-jung)*


Outsourced sales providers offer services to help organizations grow their sales and revenue via external teams of sales experts. Outsourced sales providers are supported by specialized technologies, tailored training, and expert management. These third-party sales teams assist companies in sourcing new leads and opportunities, booking qualified meetings, growing pipelines, and closing deals. Some outsourced sales providers offer the people, processes, and technologies needed for a complete sales process (including ongoing relationship management), while other providers may only offer a subset of sales process services (e.g., telemarketing, appointment setting, etc.). These providers enable companies to maintain a sales force without having to make them full-time or part-time employees.

Outsourced sales providers often include offerings similar to [lead generation services](https://www.g2.com/categories/lead-generation-services) whereby they qualify top of the funnel leads (such as webinar attendants, whitepaper downloads, website inquiries, etc.) and identify whether they are ready to be handed over to the sales team. The providers in this category may utilize [CRM software](https://www.g2.com/categories/crm) to track prospects and contacts throughout the sales pipeline and [sales analytics software](https://www.g2.com/categories/sales-analytics) to assist in forecasting sales numbers based on pipeline factors.

To qualify for inclusion in the Outsourced Sales Providers category, a services provider must:

- Assist companies in sourcing leads, as well as reaching out to customers and prospects on the company’s behalf through one or more channels (e.g., phone, email, SMS, etc.)
- Provide the ability to book appointments with potential clients that match a company’s ideal profile
