IdeasUnlimited Reviews & Testimonials
BPO Review from Kimberly Weber
We brought on IdeasUnlimited to help with our back office work so our nurses and staff could stay focused on clients. They handle scheduling, reports, emails, and client inquiries, and they picked up new tasks fast with very little training. The time we save is huge, and it makes our daily operations smoother. What I like most is they really try to fit into how we work, so it feels like they are part of our own team. The onboarding took a little time, but once we got set, everything has been running well.

BPO Review from Miriam Woodward
IdeasUnlimited has been a dependable partner for us at De Dios Consulting. They handle our scheduling, emails, research, and reports, which freed up time for us to focus on clients. What I value most is how quickly they adapt and how much they feel like part of our team. The only challenge was getting them up to speed on a few tools, but once they learned, everything has been smooth.

Medical Review from Jeffrey Bill
Working with IdeasUnlimited has been a real help for us at Sunrise Treatment Center. We brought them in to handle our medical billing so our staff could focus more on patients. They learned our system fast and cut down on errors which meant we got paid quicker and had better cash flow. Communication has always been easy and they adjust when we need something changed. What stood out most is how detailed and reliable they are. Nothing is ever perfect but they came pretty close.

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!

The Helpware team was very professional throughout the entire process and did an incredible job keeping the project on time and on budget. Communication was also great and I really appreciated their consultative approach. I would recommend without hesitation.

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.
