Key Criteria for Choosing a B2B Data Vendor

With so many B2B data vendors, it’s essential to choose wisely to avoid wasted efforts. Here are some key criteria to consider before choosing a B2B data vendor.

1. Data accuracy and recency

Inaccurate data will mislead and waste your sales efforts. As a result, you need accurate and recent data to scale through. Consider the vendor’s collection methods, sources, and verification process to determine the quality of the data. Look for vendors who offer accurate, recent, and reliable data. This ensures you’re targeting the right prospects and not wasting time and resources chasing the wrong leads.

2. GDPR and CCPA compliance

Before you choose a data vendor, verify whether they’re compliant with data regulations such as the GDPR and CCPA. Look for indicators that show whether they’re compliant. Check if they:

  • Have a compliance certification 
  • Comply with data security standards like SOC 2 Type II
  • Adhere to industry best practices
  • Have a transparent privacy policy.

Verifying their compliance status helps to prevent some legal sanctions that could impact your business.  

3. Depth and breadth of firmographic/technographic data

Most B2B data providers go beyond providing intent data for customers. They also provide in-depth firmographic and technographic data to ensure the prospects align with your business. As a result, make sure to have a clear understanding of the kind of data a vendor provides to determine whether they have what you need. Also, ensure that these data cover the breadth and depth that you need.

4. Integrations with CRMs and sales tools

A B2B data vendor that doesn’t integrate seamlessly with existing systems will disrupt your workflow. Due to this, make sure to consider whether they integrate with your current tech stack, like CRMs, outreach tools, and other tech you use. Smooth integration helps to drive efficiency in your sales process.

5. Customer support 

If your desired B2B data vendor doesn’t have customer support, chances are you won’t resolve your queries when issues arise. As a result, find a reliable vendor that offers excellent customer support to answer your questions and solve any issues that may arise when using the products. 

6. Pricing transparency and scalability

Reviewing the cost offered by B2B data vendors is essential to determine whether the cost meets your budget. If their fees aren’t publicly displayed, check for hidden fees that you may incur in the budget. Also, select a vendor that allows scalability and accommodates future changes as you grow your business.

How to Test and Compare Providers Before You Buy

1. Using free trials and demos effectively

Many B2B data vendors offer a free trial for their services. Leverage this opportunity to check out the features and determine whether it fits your needs. For instance, you may check whether it integrates with your tech stack. 

2. Benchmarking data accuracy and match rates

Test out the database, including the search functions and filters, to determine the quality and accuracy of the data. Identify the number of contacts it provides that match your ideal customer profile (ICP). 

You can also check whether their database supports needs across diverse regions. For instance, if your business has customers across the US and Europe, ensure to check whether the vendor can supply relevant leads’ details in those regions.

3. Questions to ask sales reps

Before you choose a B2B database provider, you may want to clarify some concerns with a sales representative. Here are some questions you want to ask sales representatives:

  • What industries or company sizes do you specialize in? Are there any gaps in coverage?
  • How often do you update your database? What’s your verification process
  • Can you share case studies from companies similar to mine?
  • How do you handle data compliance with regulations like GDPR and CCPA?
  • Beyond the basic subscription, what additional costs can we incur?

Asking these questions will provide valuable answers that help you determine whether you should choose the database provider. 

4. Strategies for running a pilot program

Making a full commitment without running a pilot program can waste resources and increase risk. For instance, the database provider could become incompatible with your existing system, creating disruption in your sales workflow. However, running a pilot program helps to foresee these risks and avoid any problems that may arise. 

Here are some strategies for running a pilot program:

  • Establish clear goals and objectives that you wish to learn from the pilot
  • Start with a limited scope to manage complexity and define a timeframe to carry out the pilot, e.g,. 30 days.
  • Choose 2-3 vendors that fit your requirements
  • Create identical test cases for each provider
  • Gather quantitative and qualitative feedback to measure performance
  • Evaluate the total cost of ownership, including any hidden fees.
  • Consider exiting if the provider doesn’t meet your expectations.
  • Design an implementation strategy for a successful pilot.

Conclusion

Poor data vendors deliver more than wrong numbers — they waste your time, let you miss out on valuable sales opportunities, and impact your ROI. However, choosing the right database vendor provides quality data that allows you to hit your sales target and maximize your returns.
