Customer Support Review from Manoj Thenua
I recently engaged a customer support provider to manage client service and support tasks for my healthcare-oriented platform. From the outset, their team was extremely professional, responsive and attentive. Their onboarding process was smooth, prompt, and well-organized. Throughout the project they handled all support tickets including account queries, billing questions, technical issues and general user guidance with empathy and clarity.What impressed me most was their commitment to quality: they consistently responded quickly to inquiries (often within minutes), maintained a helpful and courteous tone, and followed up until the users problems were fully resolved. Feedback from my users has been overwhelmingly positive: many praised how easy it was to get help and how satisfied they were with the assistance.Thanks to their efficient support, user satisfaction and retention improved noticeably compared to the period before they handled support. I also experienced fewer escalations and received fewer complaints overall. Their professionalism and consistency gave me peace of mind and freed me to focus on growing the platform rather than handling day-to-day support issues.Overall, working with them has been a very positive and productive experience the quality of support exceeded my expectations.

Christina P's Review Sourced from Google
Being a family owned & operated business for 75+ years, we were looking to try something new. Having a VA work for us was one of those changes we wanted to implement. Go Hire Virtual has been wonderful to work with right from the start and having a VA join our team has been a great success. Our virtual assistant, BEA SON, has been nothing short of phenomenal! She has now been with us for 1 full year and we hope to have her for years to come. BEA SON handles customer inquiries, schedules service appointments, and follows through with all tasks asked of her. I appreciate her positive attitude and her professionalism, which shows every day. Her help has given me the time to focus on other strategic products to help better our business. Thank you very much BEA SON and GHV! We are truly grateful to have you all. It has been a pleasure working together.

5 Frequently Asked Questions About Telemarketing Firms
What do telemarketing companies do?
Telemarketing agencies use phone-based direct marketing to sell products, generate leads, or book appointments on behalf of businesses, performing both outbound and inbound calls to grow sales pipelines and client relationships.
As all telemarketing interactions involve direct human contact, the approach allows them to influence potential customers’ opinions, purchasing habits, or perceptions toward a brand.
What services do telemarketing firms provide?
Telemarketing services for businesses can be split into two main categories: inbound and outbound.
Inbound telemarketing services cover customer support calls, namely technical support, order taking, billing inquiries, upselling, and virtual receptionist service, to name a few. They can support both B2B and B2C companies.
Outbound telemarketing services, also referred to as proactive outreach, are intended to boost businesses’ bottom line. This category comprises several different service types, including lead qualification, appointment setting, cold calling, customer reactivation, and more.
B2B telemarketing companies are often hired to assist non-profit organizations in soliciting donations or to collect debt and follow up on overdue accounts on behalf of other businesses.
How much do telemarketing agencies charge for their services?
Telemarketing agencies charge between $7 and $75 per hour for their services. The service cost can also vary based on location (offshore vs. onshore), campaign complexity, duration, and agent experience, with B2B telemarketing campaigns often costing more than B2C.
Other common pricing models include:
Per-lead: $35 to $60 per qualified lead
Flat-rate: $650+ for a 4-week campaign
Commission-based: 5% to 20% of each closed sale
How long do telemarketing campaigns take?
Telemarketing campaigns usually take a few months, as lead nurturing takes multiple phone calls for telemarketers to engage with a prospect and close a sale.
Although initial lead generation begins within the first few weeks, for a full, effective cycle, the campaigns are run between 3 and 6 months. The average campaign takes about 14 weeks to reach an optimum level of opportunities per day. The length also depends on the campaign type:
Pilot and trial campaigns: Usually run for 10 to 12 weeks to test the market, refine the pitch, and validate traction.
Short campaigns: 4 to 6 weeks for time-sensitive promotions or event registrations.
Long-term campaigns: 6 months to over a year for slow B2B sales cycles that require more lead nurturing.
What kind of ROI can businesses expect from telemarketing campaigns?
Lucrative telemarketing campaigns often result in a 5:1 to 10:1 return on investment (ROI), meaning $5 to $10 in revenue for every $1 spent. The return rate depends on the quality of the call lists, the persuasion skill of the callers, the product, the offer, and whether it's part of a multi-channel strategy. Notably, ROI grows over time through stronger customer retention and better targeting informed by feedback from calls.
