Comparison Guide
MVA Leads vs Warm Transfers vs Signed Retainers
Personal injury law firms have multiple options for acquiring motor vehicle accident cases. This guide compares the four primary delivery methods — web leads, inbound calls, warm transfers, and signed retainers — so you can choose the approach that fits your firm's intake capacity, budget, and growth goals.
Side-by-Side Comparison
| Web Leads | Inbound Calls | Warm Transfers | Signed Retainers | |
|---|---|---|---|---|
| Consumer Intent | Medium — filled out a form | High — initiated a call | High — spoke with intake | Highest — signed agreement |
| Pre-Qualification | Form-based screening | None (your team qualifies) | Live screening by intake specialist | Full intake + qualification |
| Delivery Method | API, email, or host-and-post | Live phone call routed to you | Live phone transfer | Signed document package |
| Speed | Instant delivery | Real-time call | Real-time transfer | Near real-time after signing |
| Your Intake Effort | Full intake required | Full intake required | Reduced — caller pre-screened | Minimal — client already signed |
| Conversion Responsibility | Your team converts | Your team converts | Shared (pre-screen + your close) | Mostly handled before delivery |
| Relative Cost Per Lead | Lowest | Low-Medium | Medium-High | Highest |
| Relative Cost Per Signed Case | Varies widely | Moderate | Often favorable | Most predictable |
| Ideal For | Firms with strong intake teams | Firms wanting full control | Firms wanting pre-screened calls | Firms wanting signed clients |
Cost comparisons are relative and vary by market, campaign, and provider. Actual pricing should be discussed directly.
When Web Leads Are the Right Choice
Web leads work best for firms with strong, responsive intake teams that can contact leads quickly after submission. They offer the highest volume potential at the lowest per-unit cost, but require your team to handle all follow-up and conversion.
The key success factor is speed-to-contact. Firms that call web leads within minutes of submission see dramatically better conversion rates than those that wait hours or days.
When Warm Transfers Make Sense
Warm transfers are ideal for firms that want to minimize time spent on unqualified callers. Since an intake specialist screens the caller before transferring, your team only handles prospects who meet your criteria.
The trade-off is higher per-unit cost compared to web leads or raw inbound calls — but many firms find the improved conversion rate and reduced intake burden make warm transfers more cost-effective on a per-signed-case basis.
When Inbound Calls Work Best
Inbound calls give your team complete control over the intake experience. The consumer has self-selected by calling, indicating high intent. This works well for firms with experienced intake staff who prefer to handle qualification themselves and want no intermediary in the process.
When Signed Retainers Are Worth the Investment
Signed retainers are the premium option — highest cost per unit, but the client arrives already signed. This works best for firms that want to minimize intake overhead, have the budget for premium case acquisition, or want the most predictable cost-per-signed-case calculation.
How to Calculate Cost Per Signed Case
Regardless of which delivery method you choose, the most important metric is cost per signed case. This is calculated as:
Cost Per Signed Case = Total Lead Spend ÷ Number of Signed Cases
A web lead at $50 that converts 5% of the time costs $1,000 per signed case. A signed retainer at $800 that your firm accepts 80% of the time costs $1,000 per signed case. The per-lead cost is different, but the per-case cost may be comparable.
Always evaluate lead providers on cost per signed case, not cost per lead alone.
