IdeasUnlimited Reviews & Testimonials
Kimberly Weber President and Founder at Iowa Home Care
5.0★
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.
Jeffrey Bill Founder & CEO at Sunrise Treatment Center

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.

Lead Generation Review from James Nolan
We worked with Reexia to support our outbound business development and lead generation efforts. The team helped us structure a targeted outreach campaign and build a relevant prospect database for our market.Communication throughout the project was clear and organised. We had bi-weekly calls to review activity and results, and Kevin was very hands-on in guiding the campaign and suggesting adjustments where needed.Results took some time to appear, but this was explained clearly at the start of the campaign and expectations were set appropriately. Once the campaign gained momentum, we began having conversations with companies that matched our target profile.Overall, it was a positive experience and we appreciated their structured approach to outbound prospecting.

Starting my internship with Protovo by my first year of engineering and becoming the junior software engineer at Protovo, it was really a great experience and time with a company like this where i got to know about many of the latest technologies and one with great work culture which every person dream for. A great boss is always a one people want in company and here I got three. Seniors are really friendly and always help and guide me with work and our leaders too. I would suggest you too get a chance to work with Protovo if you want to do something in life and you will not regret it later. Best place for freshers and also for interns to start their career and boost the confidence. Go with Protovo #protovian

Smart Outsourcing Solution took us from zero to a fully operational, globally capable support team in record time. We have worked with this team for a number of years now and could not be happier with our team members.They recruited and onboarded top‑tier talent with them available and ready to go as soon as we needed, and also handled all compliance and payroll headaches.Thanks to SOS’s 24/7 tech‑support desk, our new team now supports Fortune 500 customers across three continents without a hitch; issues are resolved in minutes, not days.Weekly progress calls keep us fully informed while their proactive approach means we scale smoothly, with no need to set up a local entity.If you want a turnkey way to build a remote team that can confidently serve the world’s biggest enterprises (complete with rock‑solid tech and SaaS support) I can’t recommend Smart Outsourcing Solution highly enough.

ben howlett's Review Sourced from Google
We were overwhelmed by seasonal spikes in customer enquiries, plant care scheduling, and online orders across multiple garden centres. Smart Outsourcing Solution’s Employer of Record (EOR) service helped us quickly hire a remote horticulture support team in the Philippines, handling compliance, payroll, and onboarding end‑to‑end. Result: faster response times, better stock and planting coordination, and the ability to scale our support across Southeast Asia without setting up local entities.Project OverviewWe needed reliable admin and customer support coverage to manage planting schedules, subscription garden kits, and care advice lines during peak growing months. SOS acted as our EOR, standing up a trained offshore workforce that now supports order management, chat support, and seasonal campaigns.What Do You Like the Most About Working with Smart Outsourcing SolutionThey understood seasonal labour swings and let us scale remote teams up or down without HR complexity. Compliance and payroll were fully managed, so we could focus on growing healthy gardens — not navigating labour law.What Can Smart Outsourcing Solution Improve on FurtherA self-serve forecasting tool tied to our sales cycles would help us plan headcount ahead of spring and holiday promotions.Results & RecommendationIf you run a gardening or horticulture business and need flexible staffing, an Employer of Record (EOR) partner in the Philippines is a cost‑effective, compliant way to support growth, customer care, and seasonal demand across Southeast Asia.

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.
