From the very start, their team was very professional, communicated in a timely manner, and was very familiar with B2B lead generation. We were just surprised at their team culture and their desire to work hand-in-hand with our team. It felt like they were not an external vendor but a true partner in all respects.Throughout our working time together, Martal always produced excellent work while keeping us informed and engaged. They are solution-oriented, proactive, and willing to share ideas that enhance performance. It is not often that you find a team that is so concerned about your success.What we value most is their honesty and commitment to building something that will last. They don't seek quick wins but work to build outcomes that last and can potentially expand.

Customer Support Review from Maria Maidana
Helpware has been a trusted partner for SquadLocker for several years now for customer success. Our Customer Onboarding Team continues to shine through every administrator that interacts via our Live Chat channel for store help. Anzhelika is my Onboarding Lead and we work hand in hand in making any and all decisions for team enhancements. She delights both DIY and Enterprise administrators across multiple channels here at SquadLocker. I would not be as successful without Anzhelika by my side. I forsee using Helpware for years to come!

Princess's Review Sourced from Google
I wanted to take a moment to share my experience going through the hiring process here, because it genuinely blew me away. We’ve all been through frustrating interview cycles, but this was the exact opposite. From day one, the entire process was incredibly smooth and stress-free.What really made an impression on me was how professional, kind, and down-to-earth the team was. During my interviews, it didn't feel like a rigid interrogation; instead, it felt like a great, two-way conversation. They genuinely cared about my career goals and took the time to answer all of my questions.Communication was amazing, too. I was never left hanging or wondering what the next steps were, which I appreciated so much. Walking away from the process, I just felt valued as a person, not just a resume. I am so excited to be joining such a thoughtful and professional team!

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.
