Predictika · Semi-trailer quotes

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

An AI sales agent prepares a quote for curtainsider semi-trailers: the model and version, the axles, brakes and suspension, options such as Roll Stop or a back door extension, the payload, pallets and cargo height, the quantity, the warranty, a discount and the total. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits what and returns a verdict, every reason and the total it computed.

Scope: Wielton Curtain Master, Mega Curtain Master, Coil Master, Dropside Master and Platform Master: version, axles, options, payload, pallets, height, warranty, discount and total. See everything this validator covers

This validator models Curtain Master family trailer quotes, not just the scenarios shown below.

  • Model and version — the TIR and Intermodal versions fit only some bodies, and some models are built with three axles only.
  • Axles and suspension — lift and steering axles need three air-suspended axles, and the curtain and coil models use air suspension only.
  • Options — Roll Stop and the vertical load-securing system fit curtain bodies only, and the back door extension and the tire, beverage and steel transport systems fit only some models.
  • Capacity — the payload, the number of euro pallets and the cargo height must stay within the limit of the model.
  • Discount, warranty and total — a discount above 5 percent, a fleet order and a five-year warranty need a person to confirm them, and the total the quote states is compared with the total computed from the modeled price list.

Any trailer quote that touches these rules is in scope — not only the scenarios pictured here. Product family and model names, versions and option names follow the public Wielton website. The axle, suspension and brake options, the payload, pallet and height limits, which options fit which model, the warranty terms, the discount and fleet thresholds and every price are modeled from comparable trailers, not published by Wielton; all prices are illustrative, in euros.

The AI sales agentBuilds the trailer quote from the conversation with the customer 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
Axles, suspension and options that depend on the modelOnly with workarounds
A compatibility table or one rule per model and option, edited again whenever a model or option is added.		The model, the axles, the suspension and the options are checked together on every call.
Capacity limits that depend on the modelOnly with care
Payload, pallets and cargo height each have a different limit for each model, so each is its own lookup and comparison.		The limits are looked up inside the model and compared on every call.
A discount, fleet and warranty that need approvalOnly with care
Each is a separate threshold, some of them blocking and some needing a person, so the rules must be ordered and kept apart.		Every threshold is checked in the same pass and each finding says whether it blocks or needs a person.
A total reconciled with a stated oneOnly with workarounds
The total comes from the model, options, axles, quantity and discount, and a separate calculation is needed to compare it with the figure the quote states.		The total is computed inside the model and compared with the stated one on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for curtainsider semi-trailers: the model and version, the axles, brakes and suspension, and more. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of what fits what and returns a verdict, every reason and the total it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 3 Mega Curtain Master TIR trailers, 2 axles, disc brakes, air suspension, with a back door extension, a payload of 27,000 kilograms. The quote states a total of 116,160 euros. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with six findings, all in one answer. The Mega Curtain Master and the Coil Master are built with 3 axles only; the quote has 2 axles. The payload of 27,000 kg is over the 17,350 kg this configuration can carry. 34 euro pallets do not fit; this model carries 33. The other three are on screen.
    6. 
      
  6. The validator returned six 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 a discount, fleet and warranty that need approval, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the axles to 3, the payload to 24,500 kg, the euro pallets to 33, the cargo height to 300 cm and the total stated on the quote to 153,126. Two more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The six blocking findings are cleared; one approval remains for a person: discount above 5 percent.
    13. 
      
  13. Six problems caught in one call, fixed in one pass, and the corrected quote now goes to a person for approval. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
