When It Makes Sense to Invest in Lead Generation Services

Are you spending a small fortune on marketing for leads and not getting any results? Are your conversion rate percentages floating at the bottom of the weekly progress report? If you answered yes, then you need lead generation services. 

Another thing to focus on is the quality of your current leads, if you have sales reps calling leads and those leads don’t understand why you’re calling or are confused about your product, you need better qualifiers.   

Lead gen services can make sure you’re not wasting your resources speaking to people that don’t care about your services. 

You also might need a lead generation service in the opposite scenario. That’s right, a lead generation service can be a lifesaver if you have too many leads already.

Let’s say your marketing manager is a rockstar. They have leads calling in left and right, your CRM is flooded with people interested and ready to get more information. 

But, you can’t reach them fast enough. Yup, it happens.

And if you don’t have the resources to reach out to a lead within 24 hours you can lose that momentum and eventually the sale. If this is becoming a problem for you, investing in a lead gen provider that does outbound calls for you is a necessity. They’ll help qualify everyone so your team only spends time on the red-hot prospects.

Think about it… 

How much cash is sitting on the table waiting but you can’t collect?

Getting service to help with lead generation will prevent sporadic sales and allow you to sustain a thriving operation.

Once a lead’s qualified, your sales team is the first to know with a direct event on your calendar so you can close the detail, complete with detailed call notes and what to expect.

Upcall’s team handles the grunt work of cold calling and nurturing so your salespeople can follow through and convert warm leads into paying customers.

Methodology For Choosing The Best Lead Generation Services

Now that we’ve talked about how you can get leads that are qualified for your business. Let’s talk about why these lead generation services made this list and how our methodology can help you choose which one works best for you.

Price Point Analysis

You might notice that there is no pricing information on the list. That’s because most lead generation providers customize your plan based on your needs. 

So, you should get a quote from your top choices. Making sure the price fits into your budget is key. If not, you could have a negative return on investment because of overspending on lead generation. 

Many companies offer various payment models and some only charge you for the leads you get. Some can bill you for the month, or even per campaign.

Niche Driven 

We recommend focusing on a lead generation company that specializes and doesn’t try to be everything to everyone. The reason is because you won’t get the most qualified leads for your business unless your lead gen service is focused on your industry or niche. 

Some services focus on a small range of industries, while others are tailored to specific sizes of business. 

You want your leads to be the best and also hyper-relevant to your industry. That starts with focusing on a lead gen company that has experience in your field.

Lead Generation Strategy

Strategy is everything, and how a company is going to find your leads matters greatly. Every company has their own spin on how they find leads and qualify them. 

A good question to ask is, “how will my leads be delivered?” Will you receive them in real time or in batches? Can they be delivered via text messages as well as in emails? Will they include scoring?

Furthermore, how active is the service in the steps after collecting leads? Do they set appointments for you, or even pre-sell to leads?.


Honestly, you know that every company is going to put their best foot forward on their website. It’s to be expected. 

But social media and case studies don’t lie. They give you the real truth about a service and if the company is providing a service worth spending your money on. 

It’s extremely important you do some digging. Read reviews, case studies, social posts, and more. Don’t make a decision until you feel confident that what the provider is saying matches what real clients are saying and that leads have actually been generated.
