How to quantify the true cost of bad lead provider data

Bad lead provider data costs you more than just the price of the lead itself; it eats into your time and resources. You need to quantify these hidden costs to accurately evaluate your lead sources and improve your profitability.

Time spent on unqualified leads

Every minute your team spends calling or following up on a lead with bad data is wasted time. This includes numbers that are disconnected, wrong property addresses, or owners who are not motivated.

Track the average time spent per lead from initial contact to qualification or disqualification. Multiply that by the number of bad leads you receive. Suppose your team spends 15 minutes per lead and 30% of your leads have bad data; that adds up quickly.

Loss of opportunity for good leads

When you are busy chasing bad leads, you are not chasing good ones. This is an opportunity cost. A good lead could be nurturing a hot prospect or closing a deal.

Every hour spent on a bad lead is an hour not invested in a potentially profitable deal. If you consistently miss good deals because your time is consumed by poor data, that is a quantifiable loss.

Increased marketing and skip tracing expenses

If the lead provider's data is incomplete or inaccurate, you might spend additional money trying to fill in the gaps. This could mean more skip tracing to find current contact information or paying for additional property data.

Every extra dollar spent on enriching bad data adds to the true cost of that lead. You might also run marketing campaigns to numbers that are no longer valid, wasting ad spend.

Damage to team morale and burnout

Consistently working with bad data can be incredibly frustrating for your acquisition team. This can lead to decreased morale, lower productivity, and even team member burnout.

While harder to put a dollar figure on, a demotivated team is less effective. High turnover or reduced performance due to frustration directly impacts your ability to close deals.

Reputational risk with sellers

Calling or texting someone with incorrect information, or about a property he or she no longer owns, can create a negative impression. This can damage your reputation in the market.

A negative reputation can make it harder to acquire good deals in the future, as sellers might be less likely to trust your outreach. This is a long-term cost that accumulates over time.

Holding your lead source accountable

Once you start tracking these hidden costs, you have concrete data to discuss with your lead provider. Share your findings and ask for improvements in data quality or adjustments to pricing.

Companies like Speed to Seller focus on providing verified replies, aiming to reduce these hidden costs for you. Understanding and quantifying these issues helps you choose and hold lead sources accountable for the quality of their data.

Questions people ask

How can I tell if a lead provider's data is bad before buying a lot of leads?

Start with a small test batch of leads. Track the success rate, contact rate, and data accuracy. Compare these metrics to your expectations and other sources before scaling up your purchase.

What kind of specific metrics should I track to quantify bad data costs?

Track calls made to wrong numbers, time spent researching incorrect property details, additional skip tracing costs per lead, and the contact rate for each lead batch. This gives you concrete numbers.

Should I ask for a refund for leads with bad data?

Most lead providers will have a policy regarding bad data. It is worth discussing your findings and requesting a credit or refund, especially if a significant portion of the leads are unusable. Have your data ready to back up your claim.
