Vendor selection processes are high-stakes, yet all too often, they are unstructured. No one trains you to evaluate vendor choices, resulting in costly mistakes or poor-fit tools.
This guide provides a repeatable process for making confident, ROI-driven choices. Using a data vendor as an example, we’ll walk through clear steps for defining needs, setting criteria, shortlisting, demoing, and scoring.
Let’s dive in. 👇
Before exploring any features or pricing models, you need clarity on the problem you’re solving. Are sales reps spending time chasing dead contacts? Is marketing wasting budget on bad-fit leads? These needs inform what kind of vendor will genuinely add value.
When we talk to customers, here are some common goals we see:
Let’s look at some examples now for each of the Cognism personas.
In modelling data for SDRs, we detail how SDR teams can fall into inefficiency traps without high-quality, targeted contact data. One common issue is that reps call into the wrong personas or outdated numbers, which leads to burnout and low pipeline contribution.
A defined business objective might be:
“Reduce SDR time wasted on dead contacts by 50% through more accurate mobile data.”
This kind of clarity focuses the rest of the selection process.
In our post about targeted campaigns modelling, we explain how bad data wrecks campaign performance across paid ads and outbound.
You might set this objective: “Enable marketing to launch 1:1 ABM campaigns to 500 ICP accounts with verified contact details and job change alerts.”
That single objective defines your ICP, intent criteria, and data freshness requirements—all crucial later during vendor demos and shortlisting.
Allbound modelling frames how multiple go-to-market teams often work in silos with sales and Marketing; each buying or using their own tools.
Your objective might be: “Unify GTM teams around a single, shared source of truth for contact, company and account data.”
This frames your vendor search toward tools that support multiple use cases and integrations, not just SDR dialling tools or marketing databases.
Once you’ve defined your business needs, it’s time to turn them into evaluation criteria. These are the measurable standards you’ll use to assess whether a vendor can actually deliver on what you need.
Skipping this step can lead to decisions based on the flashiest demo or the cheapest quote. Instead, your evaluation should be anchored in what’s required to solve your problem.
Here’s an example of how you’d map each criterion to a business objective:
|
Business objective |
Evaluation criteria |
|---|---|
|
Improve SDR connect rates |
Verified mobile phone coverage |
|
Reduce compliance risk |
GDPR/CCPA compliance & audit trails |
|
Consolidate GTM tools |
Breadth of use cases (sales, marketing, ops) |
|
Improve data usability |
CRM integration and enrichment options |
|
Target new regions |
Geographic data coverage (EMEA, APAC, etc.) |
To make scoring easier later, organise your criteria into logical groups. For B2B software or data vendors, common categories include:
Once you’ve defined your business objectives and nailed down your evaluation criteria, it’s time to create a list of prospective vendors worth serious consideration.
This isn’t just about Googling “best data provider” or looking at G2’s top-ranked tools. Your shortlist should be built on fit, not just popularity.
So, how big should this shortlist be? Recent chatter online and research from Wynter have suggested that software buyers often only shortlist three vendors to demo with.
But honestly, it may be more before you can whittle the list down to who to demo with. Your organisation may have an internal process whereby you'll need to initially shortlist 5-10 vendors to compare across the selection criteria to show due diligence.
Use a combination of methods to create a reliable list:
After shortlisting your top 3–5 vendors, the next step is to invite them to demonstrate their product and/or submit a tailored proposal. A good demo from potential suppliers will be tailored to the business needs you identified at the start.
However, unfortunately, there are plenty of demos that are way too vague. A tip for here is not just accepting the vendor's standard pitch deck, set clear expectations upfront.
Send a demo brief that includes:
One of the best ways to test a vendor’s value is with a real-world scenario. Here's an example of what that would look like for a data vendor.
Provide a sample list of accounts or contacts from your ICP and ask the vendor to:
You’re not looking for a perfect number—you’re looking for fit. The vendor who shows how their platform works with your ICP and tech stack will always outshine the one who walks through UI features.
Watch out for:
The best vendors will be upfront—even if they don’t check every box. The worst will try to distract with overpromises and feature overload.
What to do after you've had the demo?
Once you’ve completed the demos and reviewed proposals, it’s decision time. But without a structured scoring method, you risk defaulting to:
To avoid that, use a vendor scorecard—a decision-making framework that lets you compare each provider based on your criteria.
Start by listing your key criteria, and assign a weight to each based on how important it is to your business. Then, score each vendor on a 1–10 scale.
You'll need to align the scorecard to your use case, for example:
That’s why in targeted campaign modelling, the team weighted job title accuracy and intent data higher than price.
Even after a great demo and a strong scorecard performance, you’re not done yet.
Before signing anything, validate what the vendor has told you by speaking to actual customers, reading independent reviews, and reviewing compliance documentation. This step turns marketing claims into hard evidence.
Head over to a review site like G2, TrustRadius or Capterra for feedback that isn't as sales-filtered. Sort by:
Look for patterns in both positive and negative reviews—not just one-off rants.
Tip: You’ll also want to filter out reviews that may have been incentivised. Most review sites, like G2, will now flag these for you.
This step is essential, especially when selecting vendors that process personal data (like contact enrichment or CRM tools). Never assume compliance, ask for:
|
Compliance area |
What to request |
|---|---|
|
GDPR & CCPA |
Lawful basis for processing (e.g. legitimate interest), opt-out mechanisms |
|
Security |
ISO 27001 or SOC 2 certification, penetration testing reports |
|
Data Hosting |
Details on where data is stored and processed |
|
Contracts |
Data Processing Agreement (DPA), subprocessor list |
|
Certifications |
Privacy Shield (for US vendors), third-party audits |
After scoring, validating, and shortlisting, you’ve reached the final step in your assessment process: committing to the right vendor and securing the right deal.
This isn’t just about cost savings; it’s about ensuring long-term success, support, and flexibility. Before reaching back out to the selected vendor, align internally with all stakeholders:
Here are three common mistakes to avoid...
It’s not the number that matters, it’s the ROI. A more expensive vendor that leads to faster pipeline or higher conversion rates pays for itself.
If you're choosing a vendor for a business-critical function (like data or CRM), support is strategy. Don’t choose a vendor that can’t help you succeed post-sale.
Always run the final contract past procurement teams or legal. Watch out for:
In our volume evaluation playbook, a team compared multiple vendors based on how many records each could return. One offered significantly more but with lower accuracy and no GDPR clarity. Cognism returned fewer records, but with cleaner compliance and better usability.
That’s the mindset to take into final negotiations: value > price.
Let’s apply the process in a real-world scenario: choosing a B2B contact data vendor for your SDR team.

Tips for cross-functional buy-in:
A vendor selection process is a formal method for evaluating and choosing a software vendor based on defined business needs, budget, compliance standards, and future growth goals. This is especially important for sales, RevOps, and marketing teams procuring platforms like CRMs, sales engagement tools, and B2B data providers.
Why use a structured process?
How long your vendor selection takes really depends on the software and your internal processes. Evaluation at larger organisations takes longer due to more stakeholders being involved in the decision and protocols that need to be followed.
A vendor scorecard is a weighted matrix to evaluate them against your needs. It helps standardise decision-making.
Yes, even smaller contracts can pose data risks or hidden costs.
Absolutely, but criteria should change. A CRM might require workflow automation, while a data tool prioritises accuracy and compliance.
A structured vendor selection process leads to better decisions, builds internal trust, and strategically positions your team in the company.
Cognism is designed with transparency and buyer enablement in mind.
