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

An AI sales agent prepares a quote to upfit a fleet of emergency or service vehicles: SoundOff Signal lightbars, vehicle-specific kits, dash, grille and fascia lights, sirens and controllers, speakers, mounting and wiring, for several vehicle groups at once. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of SoundOff's public product line and returns a verdict, every reason and the total it computed.

Scope: SoundOff Signal fleet upfit packages: nFORCE and mPOWER lightbars and lights, vehicle-specific kits, nERGY 400 sirens and controllers, speakers, mounting and wiring. See everything this validator covers

This validator models a quote to upfit police, fire, EMS and utility vehicles with SoundOff Signal products, based on SoundOff's public website (its robots.txt and sitemaps) and public listings of its products. It handles any quote for these products, not just the scenarios shown. Products marked with an asterisk are illustrative; limits and prices that SoundOff does not publish are labelled typical.

  • Lightbars and lights — nFORCE exterior lightbar (48 inch), nFORCE interior bar (per-lighthead colors, vehicle-specific kit), mPOWER lightbar (48 inch), mPOWER arrow and warning LED system (vehicle-specific kit), nFORCE dash and grille lights and mPOWER fascia lights; color codes red and white, blue and white, red and amber, blue and amber, tri-color red, blue and white, plus amber and white and amber*.
  • Sirens and controllers — nERGY 400 series console siren and light controller (ETSA48-CSP), remote siren and light controller (ETSA48-RSP) and handheld remote siren (ETSA462HPP), 200 watt, with speakers; a light controller* for utility vehicles that may not carry a siren.
  • Vehicles — Ford Police Interceptor Utility (kits listed for 2020 to 2023), Chevrolet Tahoe (interior bar kit listed for 2021 to 2023), Dodge Durango and Ford F-150 (fit years assumed); up to three vehicle groups in one quote, each with its own model, year, count, parts, power feed and installation hours.
  • Checked on every call — kit fit by vehicle and model year, mounting kit that matches the vehicle, light colors for police, fire, EMS and utility agencies, controller outputs against the lights, siren watts against the speakers, total current against the spare alternator capacity and the power feed, stated total against computed.
  • Typical limits (not published by SoundOff) — every price, amp draws, spare alternator capacity, controller output counts, speaker pairing, fit years for the Durango and F-150, agency color practice (not legal advice), no sirens on utility vehicles, a 12 percent discount limit, manager approval above 6 percent and for fleets of 25 vehicles or more.

Any quote for these products that touches these rules is in scope — not only the scenarios pictured here. Not covered: SoundOff products outside the list above (nROADS, nFUSE, Blueprint, beacons, work-area lighting), other vehicle models, state law beyond the typical practice listed, installation beyond the labor hours quoted, freight and taxes. The customers are fictional.

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
Vehicle-specific kits that fit only certain model yearsOnly with workarounds
The interior bar kit and the arrow system are made for one vehicle over a run of model years. That is a pick list per kit, per vehicle, per year range, kept by hand and out of date whenever a model year changes.		Kit, vehicle and model year are checked together on every call.
A mounting kit that must match the vehicle on the roofOnly with care
An exterior bar needs the roof mounting kit made for its vehicle, and an interior bar needs none. A mismatched kit looks like any other line on the quote.		The kit is compared with the vehicle and the bar in each group.
Light colors that depend on the agencyOnly with workarounds
Police, fire, EMS and utility fleets may use different colors, and blue on a fire truck depends on a state permit. The agency type has to reach every light choice.		Colors are checked against the agency type, with blue held for a person when a permit is on file.
Controller outputs against the lights in each groupOnly with workarounds
A bar, an arrow system and every dash, grille or fascia light each take outputs, and each controller has a different number. That is arithmetic across several lines.		Outputs used and outputs available are compared for every group.
Siren watts against the speakersOnly with care
A 200 watt siren needs two 100 watt speakers, and speakers without a siren make no sense. Each is a count that depends on another part.		The siren and the speaker count are checked together.
Total current against the vehicle and the power feedOnly with workarounds
Each part draws current, each vehicle has a different spare alternator capacity, and the feed has its own rating. A quote tool rarely carries any of it.		Current is added up per group and compared with both limits.
A fleet that mixes several vehicle models in one quoteOnly when vigilant
Each vehicle group has its own model, year and parts, so every rule above has to be applied group by group. Someone has to check each group separately.		Every group is checked against every rule in the same pass.
Guidance that needs a person, such as a heavy electrical load, a large discount or a large fleetOnly with workarounds
These are judgment calls, not hard rules. Quote tools tend to either ignore them or block the quote outright.		The quote is not blocked; it goes to a person with the reason listed.
A stated total that has to agree with equipment, labor and discountOnly with workarounds
Prices come from many parts and the total typed on the quote can drift from them without anyone noticing.		The total is computed from the choices and compared with the total the quote states.
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
Click to expand
    
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.

    
1The nFORCE interior bar is a vehicle-specific kit, listed for the Ford Police Interceptor Utility 2020 to 2023 and the Chevrolet Tahoe 2021 to 2023 (fit years for the Dodge Durango and Ford F-150 are assumed). Vehicle groups outside that fit: all 1.
2The mPOWER arrow and warning LED system is a vehicle-specific kit, listed for the Ford Police Interceptor Utility 2020 to 2023 (fit for the Tahoe and Durango is assumed, and none is listed for the F-150). Vehicle groups outside that fit: all 1.
3An exterior lightbar needs the roof mounting kit made for its vehicle, and an interior bar or no bar needs none. Vehicle groups with a mounting kit that does not match: all 1.
4The light colors must suit the agency type (typical state practice, not legal advice: police may use red, blue and white; fire and EMS red, white and amber, with blue only under a state permit; utility vehicles amber and white). Vehicle groups with colors not allowed: all 1.
5Blue lights on fire or EMS vehicles rely on a state permit, so a person confirms the permit. Vehicle groups with blue lights: all 1.
6Utility vehicles are not authorized emergency vehicles, so a siren is not allowed. Vehicle groups with a siren: all 1.
7The lights need no more controller outputs than the controller provides (a bar uses 2 outputs, an arrow system 2, and each dash, grille or fascia light 1; the console controller provides 8, the remote 6 and the handheld none). Vehicle groups that need more: all 1.
8A 200 watt nERGY 400 siren needs exactly two 100 watt speakers, and speakers need a siren. Vehicle groups that do not match: all 1.
9A vehicle takes at most 4 dash or grille lights and 6 fascia lights. Vehicle groups that list more: all 1.
10A warning system drawing more than 80 percent of the spare alternator capacity needs a person to confirm the electrical plan. Vehicle groups above 80 percent: all 1.
11The warning system must not draw more current than the spare alternator capacity of the vehicle. Vehicle groups over that capacity: all 1.
12The warning system must not draw more current than the power feed and fuse rating. Vehicle groups over that rating: all 1.
13Every vehicle group needs at least one vehicle. Vehicle groups with none: all 1.
14Fleet orders of 25 vehicles or more are confirmed by a person before they are sent; this one has 25 vehicles.
15A discount of $2,863 on a list price of $46,050 is more than 6 percent and needs a manager to approve it.
16A discount of $5,626 on a list price of $46,050 is more than the 12 percent limit.
17The quote states a total of $26,130, but the equipment, installation and discount give $27,630.
18The quote has no vehicle group; at least one vehicle group with a vehicle model is needed.

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 to upfit a fleet of emergency or service vehicles: SoundOff Signal lightbars, vehicle-specific kits, dash, and more. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of SoundOff's public product line 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 the warning-light and siren upfit for the Harlan Ridge County Sheriff's Office. Group 1 is 10 Ford Police Interceptor Utility vehicles of model year 2024, with the nFORCE interior bar kit, the mPOWER arrow and warning LED system and 2 nFORCE dash and grille lights. The rest of the request is on screen. The quote states a total of $102,818.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with eight findings and two approvals, all in one answer. The nFORCE interior bar is a vehicle-specific kit, listed for the Ford Police Interceptor Utility 2020 to 2023 and the Chevrolet Tahoe 2021 to 2023 (fit years for the Dodge Durango and Ford F-150 are assumed). Vehicle groups outside that fit: 1 of 3. The mPOWER arrow and warning LED system is a vehicle-specific kit, listed for the Ford Police Interceptor Utility 2020 to 2023 (fit for the Tahoe and Durango is assumed, and none is listed for the F-150). Vehicle groups outside that fit: 2 of 3. An exterior lightbar needs the roof mounting kit made for its vehicle, and an interior bar or no bar needs none. Vehicle groups with a mounting kit that does not match: 1 of 3. The other five are on screen.
    6. 
      
  6. The validator returned eight blocking findings and two approvals 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 and against the stated total.
    7. 
      
  7. What this shows: for vehicle-specific kits that fit only certain model years, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the group 1 lightbar to nFORCE 48 inch exterior lightbar, the group 1 speakers to 2, the group 2 dash and grille lights to 2 and the stated total to $117,044. It sets the group 1 mounting kit to Roof mounting kit for the Ford Police Interceptor Utility. Three more changes are on screen. It removes the group 1 arrow system and group 3 arrow system.
    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. It starts with nFORCE 48 inch exterior lightbar and Roof mounting kit for the Ford Police Interceptor Utility; the other 21 lines are on screen.
    13. 
      
  13. All ten earlier findings are cleared, and the validator's total, $117,044, matches the quote.
    14. 
      
  14. Ten problems caught in one call, fixed in one pass, and a clean $117,044 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    15.
