An AI sales agent's coachbuilt motorhome order, checked before it goes out

An AI sales agent prepares an order for a coachbuilt motorhome from the C1-tourer T range: the floorplan, the chassis and the weight class, with the base price and the vehicle length it states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the model cards on the public Carthago C1-tourer T page and returns a verdict, every reason and the figures it computed.

Scope: Carthago C1-tourer T coachbuilt motorhomes: five floorplans, Fiat Ducato or Mercedes-Benz Sprinter, lightweight 3.5 t or comfort 4.2 t, the price and the vehicle length shown on the page. See everything this validator covers

This validator models an order for one Carthago C1-tourer T motorhome at a time, based on the model cards of the public C1-tourer T product page, not just the scenarios shown below.

  • Floorplans covered — T 143 KB-LE, T 145 RB-LE, T 147 RB-LE "K", T 148 RB-QB "K" and T 148 KB-LE H, on a Fiat Ducato or a Mercedes-Benz Sprinter chassis, as a lightweight 3.5 t or a comfort 4.2 t model.
  • Availability — the T 148 KB-LE H is offered only in the comfort 4.2 t class, not as a lightweight model.
  • Price and length — the base price and the vehicle length the quote states must equal what the page shows for that floorplan, chassis and weight class (the length depends on floorplan and chassis only). The page shows the prices with a £ sign. The page shows no price and no length for the T 148 KB-LE H, and its T 143 KB-LE Fiat lightweight price conflicts with the headline "from" price, so those figures are not checked.

Any order for these five floorplans that touches these rules is in scope — not only the scenarios pictured here. Not covered: options, upholstery and worlds of style and their prices (the page shows no per-floorplan option rules or option prices, so none are modeled and there is no line-item quote), other C1-tourer ranges and other Carthago motorhome lines, chassis and motor details, and dealer or country differences. The page remains the final authority.

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 floorplan that exists in only one weight classOnly with care
Each floorplan and weight class pair is a product rule or a restricted choice that someone has to keep in step with the catalog.		The floorplan, chassis and weight class are in one request and checked together.
A stated base price compared with the price shown for the exact floorplan, chassis and weight classOnly with care
The price is usually looked up when the quote is priced; a figure typed into the order is just text unless a rule compares it.		The stated price is a field of the request and is compared with the page price on every call.
A stated vehicle length that depends on the floorplan and the chassisOnly with workarounds
The length differs between the Fiat and the Mercedes-Benz chassis of the same floorplan, so it needs a lookup on two fields that nothing compares with what was typed.		The stated length is a field of the request and is compared on every call, together with the price.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so one error is fixed and the next one appears.		All findings come back together, whatever order the choices arrived in.

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 an order for a coachbuilt motorhome from the C1-tourer T range: the floorplan, the chassis and the weight class. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the model cards on the public Carthago C1-tourer T page 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 a Carthago C1-tourer T 147 RB-LE "K" on a Mercedes-Benz Sprinter chassis as a comfort 4.2 t model. The order states a base price of 100,120 pounds and a vehicle length of 711 cm. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The quote states a base price of 100,120 pounds; the price shown on the Carthago page for this floorplan, chassis and weight class is 105,210 pounds. The quote states a vehicle length of 711 cm; the length shown on the Carthago page for this floorplan and chassis is 728 cm.
    6. 
      
  6. The validator returned two 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 stated base price compared with the price shown for the exact floorplan, chassis and weight class, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the stated base price as to 105210 and the stated vehicle length as to 728 cm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. The validator also returns the line-item quote, on screen.
    13. 
      
  13. Both earlier findings are cleared, and the validator's figure matches the quote.
    14. 
      
  14. Two problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
