An AI sales agent's trailer suspension order, checked before it goes out

An AI sales agent prepares an order for an INTRAAX trailer air-ride suspension with a model, a capacity, a ride height, an axle layout, a load and a stated total capacity. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specification tables Hendrickson publishes and returns a verdict, every reason and the figures it computed.

Scope: INTRAAX trailer air-ride suspensions (AAT, AAL, AANL, AANLS, AAEDT and AAEDL) and the INTRAAX SP AAZ slider: capacity, ride height, axle layout and spread, load and stated capacity. See everything this validator covers

This validator models orders for the INTRAAX suspension models AAT, AAL, AANL, AANLS, AAEDT and AAEDL and the INTRAAX SP AAZ platform slider, not just the scenarios shown below.

  • Capacity and ride height — each model is listed in particular capacities (for example the AAT in 23K, 25K and 30K) and each capacity has its own list of ride heights in inches; a combination that is not listed is blocked.
  • Slider layout — the AAZ slider is listed as a tandem system at 46,000 pounds with 49, 60 or 72 inch axle spreads and a single axle system at 23,000 pounds, with I-beam centers of 37, 38, 43 or 44 inches.
  • AANLS axle spreads — listed as a single, tandem, tri- or quad-axle suspension, with tandem spreads up to 60 inches and tri- or quad-axle spreads up to 144 inches in total.
  • Load and stated capacity — the load the order needs is compared with the capacity of the selected model and axle count, and the total capacity the order states is compared with the computed one. Hendrickson lists the axle rating for structure only (for example 25,000 pounds for the 30K AAT and AAL), so a load above it needs a person to confirm the axles.

Any INTRAAX order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the product pages read list none, so this validator produces no price build-up or line-item quote), weights, other Hendrickson suspension families, axle spreads for models whose pages list none, and brakes, wheels and tires, which Hendrickson rates separately. The model reflects the product pages read in October 2026.

The AI sales agentBuilds the suspension order from the conversation and says it is ready.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A ride height that is listed only for some capacitiesOnly with care
Each model and capacity has its own list of ride heights, so each pairing needs its own rule, and the lists have to be kept in step with the published tables.		The model, the capacity and the ride height are in one request and checked together on every call.
Slider layout: tandem or single, spread and I-beam centersOnly with care
Capacity decides the axle count and the layout lists are fixed, so this takes several linked rules for one product family.		The slider choices travel in one request and each is checked against its listed values.
A stated total capacity that disagrees with the model, capacity and axle countOnly with workarounds
The total is a derived figure; checking a stated total against it takes extra formulas that interact with the rest of the rules.		The stated total is a field in the request and is compared with the computed one.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for an INTRAAX trailer air-ride suspension with a model, a capacity, a ride height. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specification tables Hendrickson publishes and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an INTRAAX AAZNT 46K suspension as a tandem axle layout at a ride height of 18 inches, with an axle spread of 55 inches and I-beam centers of 40 inches. The order states a total capacity of 46,000 pounds. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. A ride height of 18 inches is not listed for the selected INTRAAX model and capacity. The tandem INTRAAX SP slider is listed with axle spreads of 49, 60 or 72 inches; the quote has 55 inches. The INTRAAX SP slider is listed with I-beam centers of 37, 38, 43 or 44 inches; the quote has 40 inches.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for slider layout: tandem or single, spread and I-beam centers, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the axle spread to 60 inches and the i-beam centers to 43 inches.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. A ride height of 18 inches is not listed for the selected INTRAAX model and capacity.
    12. 
      
  12. Two findings cleared; still blocked on ride height not offered for this model and capacity.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the ride height to 16 inches.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    19.
