Ping/post and rules-based routing are the two dominant architectures for lead distribution software. They solve the same underlying problem — getting the right lead to the right buyer — but through completely different mechanisms, with different tradeoffs on speed, complexity, and price.
The distinction matters when you're choosing a platform, because the two architectures aren't interchangeable. Tools built for one don't gracefully support the other, and picking the wrong model means paying for complexity you don't need or hitting architectural limits when your operation grows.
How ping/post works
Ping/post is a two-phase auction protocol:
- Ping: The router sends a stripped lead — typically name, geography, and a few qualifying signals, but not full contact details — to a pool of registered buyers simultaneously.
- Bid collection: Each buyer evaluates the stripped lead and responds with a bid price or a pass, usually within 2-5 seconds.
- Post: The router selects the highest bidder (or the buyer who meets the floor price) and sends the full lead to that buyer only.
The advantage is real-time price discovery: you're guaranteed the best current market price for each lead. The cost is latency (2-10 seconds per lead), complexity (buyers must integrate a bidding API), and the need for enough competing buyers to make auctions meaningful. Boberdoo ($1,000+/mo) and LeadProsper ($499+/mo) both support ping/post, and both are designed around marketplace operations with many buyers.
How rules-based routing works
Rules-based routing skips the auction entirely. When a lead arrives, the router evaluates buyers in a priority order you've configured, checking each buyer's conditions in sequence:
- Does the lead's zip fall within the buyer's territory?
- Is the buyer within their daily cap?
- Is it currently within the buyer's operating hours?
- Does the lead's score meet the buyer's threshold?
The first buyer whose conditions all pass receives the lead. Delivery happens via webhook or email, typically in under a second. There's no bidding, no latency from waiting for buyer responses, and no open registration — your buyer list is fixed and configured in advance.
Head-to-head comparison
| Dimension | Ping/Post | Rules-Based |
|---|---|---|
| Delivery speed | 2-10 seconds (auction latency) | Under 1 second |
| Revenue optimization | Real-time price discovery | Fixed pricing per buyer |
| Buyer onboarding | Buyers need bidding API integration | Simple webhook URL per buyer |
| Ideal buyer count | 20+ competing buyers | 2-15 direct buyers |
| LeadMove support | No | Yes, from $149/mo |
| Boberdoo support | Yes (core feature) | Yes |
| LeadProsper support | Yes | Yes |
| Complexity | High (auction ops, floor pricing, bid analytics) | Moderate (rule configuration) |
When ping/post is the right choice
Ping/post makes sense when: you're operating an open lead marketplace with 20+ buyers who actively compete on price, your leads are sold in verticals where per-lead value varies widely (mortgage, insurance, solar at high volume), and you have the operational capacity to manage auction dynamics — floor prices, bid analytics, buyer credit limits.
High-volume mortgage and insurance aggregators run ping/post because the revenue uplift from real-time bidding is meaningful at scale. If your average lead sells for $50 and you process 10,000 leads/month, even a 10% bidding premium is $5,000/mo — enough to justify the infrastructure cost.
When rules-based is the right choice
Rules-based routing fits agencies with direct buyer relationships where pricing is negotiated in advance. Your buyers know what they pay, you know who gets which leads, and the routing logic reflects geographic exclusivity, capacity, and schedule rather than real-time price competition.
For agencies managing 2-15 buyers in solar, home services, mortgage, or insurance with direct contracts, rules-based distribution is simpler to operate, faster to set up, and significantly cheaper. LeadProsper starts at $499+/mo with ping/post included whether you need it or not. A focused rules-based tool like LeadMove starts at $149/mo for the same core routing workflow without auction overhead.
Ping/post and rules-based routing aren't better or worse in absolute terms — they serve different business models. The right question is whether your buyers compete for leads on price (ping/post) or whether you have direct relationships with known, stable pricing (rules-based). Most growing agencies are firmly in the second category.
