The personal injury market hit $61.7 billion in 2025 (IBISWorld, 2025). That number attracts legitimate lead vendors and predatory ones in equal measure. Only 7% of PI leads set consultation appointments (MyCase 2024 Benchmark Report), which means the vendor you choose determines whether you're buying contact opportunities or burning cash.

Most firms evaluate lead vendors by asking one question: "How much per lead?" That's the wrong starting point. Price tells you nothing about consent documentation, return policies, source transparency, or delivery speed. The firm paying $400 per exclusive lead from a vendor with verified consent and a 48-hour return window will outperform the firm paying $150 per lead from a vendor who can't produce a single TrustedForm certificate.

At Claim Supply, we evaluate vendors using the same criteria listed below. This is the exact checklist we apply before routing a single lead through our infrastructure. If a vendor can't satisfy these 15 points, we don't work with them.

TL;DR: Evaluate lead vendors on 15 criteria spanning compliance, quality, delivery, and commercial terms. The three non-negotiables: TrustedForm certificates (or equivalent consent proof) for every lead, a written return policy with a 24-48 hour window, and full transparency on lead sources. Run a 30-60 day trial buying 50+ leads before committing to volume. For the complete framework, see our pillar guide to buying MVA leads.

Why Does Vendor Selection Matter More Than Lead Price?

The wrong vendor doesn't just waste money. It exposes your firm to TCPA lawsuits averaging $6.6 million in class action settlements (LeadGen Economy TCPA Analysis, 2025). TCPA penalties run $500 to $1,500 per violation, and courts have consistently ruled that the firm making the call bears liability, not the vendor who generated the lead. Your vendor's compliance failures become your legal problem.

Beyond litigation risk, vendor quality directly controls your conversion economics. Exclusive leads from a transparent vendor convert at 10-15% when contacted within 60 seconds (Velocify). That same $300 lead from a vendor with poor targeting or stale data might convert at 3-5%, turning a 6:1 ROI into a breakeven or loss.

Consider the math. Buy 100 leads at $300 each from Vendor A (verified consent, real-time delivery, 20% conversion). You sign 20 cases. The average car accident settlement is $37,249 (Brown & Crouppen, 2025) with a 33% contingency fee, earning $12,292 per case. Revenue: $245,840 on a $30,000 spend. Now buy the same 100 leads from Vendor B at $200 each (no consent docs, email delivery, 8% conversion). You sign 8 cases. Revenue: $98,336 on a $20,000 spend. Vendor A costs 50% more per lead but generates 2.5x the revenue.

Vendor selection isn't a cost decision. It's a risk and revenue decision. For the full ROI framework, see our complete guide to buying MVA leads.

What Are the 15 Points Every Lead Buyer Should Evaluate?

This checklist separates vendors who invest in quality from those who don't. Score each item on a 1-5 scale during your evaluation calls. A vendor scoring below 50 out of 75 isn't worth a trial.

15-Point Vendor Evaluation Checklist

Compliance & Consent

  1. TrustedForm certificates (or equivalent consent documentation) included with every lead, not available "upon request"
  2. TCPA-compliant consent language visible on all lead capture forms, reviewed by the vendor's legal counsel
  3. DNC list scrubbing performed before delivery, with documentation of scrub frequency and data sources

Lead Quality & Source

  1. Lead source transparency: vendor discloses which platforms (Google, Facebook, display, TV) generate leads and conversion rates by channel
  2. Exclusivity definitions in writing: "exclusive" means one buyer, period. No "market-exclusive" or "category-exclusive" wordplay
  3. Duplicate detection: vendor de-duplicates against their own database and provides a written policy on duplicate leads within 30/60/90 day windows
  4. Case type filtering accuracy: vendor can isolate MVA leads from other PI categories (slip-and-fall, workers' comp, med mal) with less than 5% bleed-through

Delivery & Integration

  1. Real-time delivery via API or webhook with under 10-second latency from form submission to your CRM
  2. CRM compatibility: native integrations or documented webhook specs for your platform (Clio, Filevine, MyCase, Litify, or custom)
  3. Delivery uptime SLA: vendor guarantees 99.5%+ uptime with a fallback delivery method (email or SMS) when the primary channel fails

Commercial Terms

  1. Return/dispute policy with a 24-48 hour window covering bad contact info, wrong case type, duplicate leads, and out-of-geography leads
  2. Geographic targeting precision: city-level or radius-based targeting, not just state-level, with documented accuracy rates
  3. Volume flexibility: no long-term contracts or unreasonable minimums during trial periods. Pay-as-you-go or weekly billing preferred
  4. Transparent pricing structure: per-lead pricing with no hidden fees for consent certs, delivery, or "technology surcharges"
  5. Performance reporting: vendor provides a dashboard or weekly report showing delivery volume, return rates, and lead source mix

At Claim Supply, we evaluate vendors using these same criteria. Points 1-3 are non-negotiable. If a vendor can't produce consent documentation, we end the conversation. Points 4-7 determine whether we'll run a trial. Points 8-15 determine whether we'll scale after the trial succeeds.

For a deeper dive into exclusive vs. shared lead definitions, see our breakdown of exclusive vs. shared MVA leads. For the full TCPA compliance picture, read our TCPA compliance guide for lead buyers.

Ask for three things on your first call: a sample TrustedForm certificate, a screenshot of the live lead capture form, and a copy of their consent language. If they can't produce all three within 24 hours, they don't have them.

TrustedForm certificates cost $0.15 to $0.50 per lead (ActiveProspect TrustedForm) and capture a timestamped recording of the form submission, including the exact consent language the prospect saw and accepted. When you receive a lead, you should be able to click a TrustedForm URL and watch a visual replay of what the prospect did on the page. If the vendor sends leads without these certificates, you have zero documentation if a TCPA claim is filed.

Verify the consent language itself. It should include: the name of your firm (or a clear disclosure that the prospect's information will be shared with a law firm), the word "consent" or "agree," and a statement that the prospect may receive calls or texts via automated technology. Vague language like "by submitting this form you agree to be contacted" doesn't meet the FCC's prior express written consent standard.

Run a monthly audit. Pull 10 random leads from the previous month and check their TrustedForm certificates. Verify that the consent language on the form matches what the vendor claims. We've caught vendors changing their consent language after the initial evaluation, weakening protections once they've secured the contract. Quarterly audits prevent this drift.

Watch for these consent red flags:

TCPA defense costs run $40,000 to $750,000 even if you win (LeadGen Economy, 2025). Q1 2025 saw 507 TCPA class actions filed, a 112% increase over Q1 2024. Consent verification isn't optional. For more on this topic, see consent verification tools compared.

What Return Policies Separate Good Vendors From Bad Ones?

A vendor's return policy tells you everything about their confidence in lead quality. Good vendors offer generous return windows because they know their leads are clean. Bad vendors hide behind "all sales final" policies because they know a significant percentage of their leads won't meet basic quality standards.

Return Policy Comparison by Vendor Tier Return window (hours) · Covered reasons · Credit type Elite Average Poor 0 hrs 24 hrs 48 hrs 72 hrs 72 hrs · 6 reasons · Cash refund 24 hrs · 3 reasons · Credit No returns Bad info, dupes, wrong type, out-of-geo, no-consent, no-answer Bad info, dupes, wrong type only "All sales final" policy Source: Claim Supply vendor audit data (2026)

Here's what to look for in a return policy:

A healthy return rate is 5-15%. Below 5% means you're probably not auditing leads closely enough. Above 15% means the vendor has a quality problem. Above 20% means you should be looking for a new vendor immediately.

How Should You Structure a Vendor Trial Period?

Never sign a long-term contract without running a structured trial first. The goal of a trial isn't just "see if the leads are good." It's to collect enough data to calculate your cost-per-signed-case, compare it to alternatives, and identify patterns in lead quality over time.

Duration: 30 days minimum, 60 days ideal. You need enough lead volume to calculate a statistically meaningful conversion rate. At 50 leads per month, a 30-day trial gives you 50 data points. If you're buying fewer leads, extend to 60 days. A 2-week trial with 15 leads tells you almost nothing.

Volume: Buy at least 50 leads during the trial. Small sample sizes produce unreliable conversion data. One bad week of leads could make a strong vendor look terrible. Fifty leads smooth out variance and give you a realistic picture of what ongoing performance will look like.

Track these metrics during every trial:

Run trials with 2-3 vendors simultaneously in the same geography, buying the same lead type. This controls for seasonal variation, geography-specific factors, and your own intake quality. If Vendor A converts at 18% and Vendor B converts at 9% during the same 30-day period with the same intake team, that difference is real.

Set a kill threshold. If a vendor's conversion rate falls below your breakeven point (typically 2-3% for exclusive leads priced at $200-$500), end the trial early. Don't throw good money after bad hoping the numbers improve. They rarely do.

After the trial, calculate your cost-per-signed-case for each vendor and compare. The vendor with the lowest cost-per-signed-case wins, not the vendor with the lowest cost-per-lead. A $400 lead converting at 20% ($2,000 per case) beats a $200 lead converting at 8% ($2,500 per case) by $500 per signed case.

Frequently Asked Questions

How many vendors should I evaluate before committing?

Evaluate at least three vendors side by side. Run a 30-day trial with each, buying the same volume in the same geography. Compare cost-per-signed-case, not cost-per-lead. One vendor may charge more per lead but deliver higher conversion, making them the cheaper option by the metric that actually matters.

What's the biggest red flag when evaluating a lead vendor?

Refusing to disclose lead sources. If a vendor won't tell you which platforms they advertise on or how they generate leads, they're either reselling from another aggregator (adding markup without adding value) or running non-compliant campaigns they don't want you to see. Walk away.

Should I require TrustedForm certificates from every vendor?

Yes. TrustedForm certificates cost $0.15 to $0.50 per lead and provide timestamped proof of consent (ActiveProspect). TCPA defense costs range from $40,000 to $750,000 even if you win, and average class action settlements hit $6.6 million (LeadGen Economy, 2025). The compliance cost is a fraction of the litigation risk.

How long should a vendor trial period last?

30 days minimum, 60 days ideal. You need enough lead volume to produce statistically meaningful conversion data. At 50 leads per month, a 30-day trial gives you 50 data points. At 20 leads per month, extend to 60 days so you're evaluating at least 40 leads before making a commitment decision.

What return rate is normal for a quality lead vendor?

5 to 15% is healthy. Below 5% likely means your return criteria are too narrow or you aren't auditing leads closely enough. Above 15% signals a quality problem on the vendor's side. If you're returning more than 20% of leads, the vendor's filtering or targeting is broken and you should renegotiate terms or switch vendors entirely.
