An AI sales agent's walk-in van order, checked before it goes out

An AI sales agent prepares an order for a Utilimaster walk-in van: an Aeromaster step van on a chosen chassis or a Velocity F-Series on the Ford Transit chassis, with body size, doors, options and the figures it states for the van. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specifications Utilimaster publishes for these two vans and returns a verdict, every reason and the figures it computed.

Scope: Utilimaster Aeromaster and Velocity F-Series walk-in vans: chassis, body length, height, width, doors, options, GVWR class and payload. See everything this validator covers

This validator models orders for the Utilimaster Aeromaster walk-in step van and the Velocity F-Series walk-in van, not just the scenarios shown below.

  • Aeromaster chassis and body — the Aeromaster is listed on Ford E-Series, Ford F59 and Freightliner MT45 and MT55 chassis; each chassis has its own list of body lengths (for example 12 to 18 feet on the E-Series and 14 to 30 feet on the MT55), body heights of 81 or 85 inches, and body widths that depend on the chassis.
  • Velocity F-Series body, doors and weight class — the Velocity is listed on the Ford Transit chassis in 12, 14 and 16 foot bodies, with 50, 60 and 72 inch roll-up doors and 20, 25 and 29 inch swing doors. Each body size has a listed wheelbase, and each weight class (class 2 under 10,000 pounds GVWR, class 3 over 10,000) has a listed GVWR.
  • Payload — each class and body size has a listed payload range; a request above the top of the range is blocked, and one inside the range goes to a person to confirm for the build.
  • Options and stated figures — options are checked against the sheet they appear on, and the wheelbase and GVWR the order states are compared with the listed values.

Any order for these two Utilimaster vans that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Utilimaster publishes no price list for these vans, so this validator produces no price build-up or line-item quote), other Utilimaster vans, shelving and interior layouts, and dealer or fleet terms. Assumptions: an option listed on one sheet and not the other is treated as not listed for that van; the Velocity payload range is read as a range that depends on the build, so a request inside it goes to approval; the sheet rows show dual rear wheel figures, which are used for every Velocity order; and an October 2020 launch article quoted different Velocity payload and GVWR figures, so the March 2021 sheet is used for every Velocity figure. The model reflects the Aeromaster sheet dated February 2025 and the Velocity F-Series sheet dated March 2021.

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 body length that is allowed only on some chassisOnly with care
Each chassis has its own list of lengths, so every chassis needs its own table and a rule that reads it; adding a chassis means more rules.		The chassis and length are in one request; each chassis list is checked on every call.
Body widths that depend on the chassisOnly with care
A width rule scoped to a group of chassis, kept in step with the length rules.		The same request carries chassis and width, and the finding names the allowed widths.
A payload range that depends on weight class and body size, with an approval inside the rangeOnly with workarounds
A lookup by class and size plus a separate approval path for requests inside the range; the two paths interact with the other rules.		The class, size and requested payload are in one request; block and approval come back together.
A stated wheelbase or GVWR that disagrees with the listed figureOnly with workarounds
The listed figures are derived from the body size and class; checking a stated figure against them takes extra formulas.		The stated figures are fields in the request and are compared with the listed values.
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 fixes one error and meets the next.		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 Utilimaster walk-in van: an Aeromaster step van on a chosen chassis or a Velocity F-Series on the Ford Transit chassis. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the specifications Utilimaster publishes for these two vans 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 prepare an order for a Velocity F-Series class 2 (under 10,000 pounds GVWR) walk-in van on the Ford Transit chassis. The order states a wheelbase of 156 inches and a GVWR of 10,360 pounds. 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 Velocity F-Series swing doors are listed in 20, 25 and 29 inch sizes; the order has a 30 inch swing door. The order states a GVWR of 10,360 pounds, but the listed GVWR for this class is 9,950 pounds.
    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 wheelbase or GVWR that disagrees with the listed figure, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the swing door to 29 inches and the stated GVWR as to 9,950 pounds.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's total, 9,950 pounds, matches the quote.
    13. 
      
  13. 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.
    14.
