An AI sales agent's PVC pressure pipe quote, checked before it goes out

An AI sales agent prepares a quote for PVC-U pressure pipe from the Lareter price list: the standard, pressure class and diameter, the joint, the working pressure and temperature, and the metres ordered. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published price list and returns a verdict, every reason, a line-item quote and the figures it computed.

Scope: Lareter PVC-U pressure pipes (metric, EN 1452 family) from the December 2022 price list: standard, PN class, diameter, joint type, pressure against temperature, options and the quoted total. See everything this validator covers

This validator models quotes for Lareter metric PVC-U pressure pipes (Lareter is an Aliaxis brand) in the three standards of the price list, not just the scenarios shown below.

  • What is offered — the price list is a grid of standard (UNI EN ISO 1452, NF EN 1452, DIN 8061/62), PN class (6, 10, 12.5, 16, 20, 25) and outside diameter (16 to 500 mm); a combination that is not in the list is blocked, and one marked “on request” goes to a person.
  • Joints — plain ends, rubber ring socket (from 40 mm), Power-Lock rubber ring socket (from 63 mm) and solvent socket (from 20 mm), each checked against the diameter.
  • Pressure and temperature — the working pressure each PN 6, PN 10 and PN 16 pipe carries at 20, 40 and 60°C is checked against the duty; PN 12.5, PN 20 and PN 25 are rated at 20°C only, so a warmer duty goes to a person.
  • Price and options — the list price per metre in 6 m lengths on up to two lines, added into a line-item quote and compared with the total the agent states; colours other than dark grey and lengths other than 6 m are on request.

Any quote for these pipes that touches these rules is in scope — not only the scenarios pictured here. Not covered: fittings, sewer, threaded, inch-size (BS) and other pipe ranges, other Aliaxis brands, discounts, freight and tax. Assumptions: prices are the printed list prices (euro per metre, ex works) from December 2022 and may have changed; an order is a whole number of 6 m lengths; the Power-Lock gasket is treated as the rubber ring joint from 63 mm, as the price list text describes it.

The AI sales agentBuilds the pipe quote from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, the line-item quote and the computed figures.

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 size that exists only in some standard and PN combinationsOnly with workarounds
The list is a grid of about 180 valid cells across three standards, six PN classes and 22 diameters. In a rules-based CPQ that is a large compatibility table to build and keep in step with each new price list, and every missing cell needs its own message.		The grid is part of the model: any standard, class and diameter is looked up and a missing cell is reported with the values chosen.
Working pressure that falls as the temperature risesOnly with workarounds
The rating depends on the PN class and a temperature band, and is compared with the duty entered on another line, so it needs a cross-field rule for every class and band.		Class, temperature band and duty are in one request and the rating is checked with everything else.
Joints offered only above a minimum diameterOnly with care
One rule per joint type that compares it with the diameter. It works, but each rule is another place to keep current.		Each joint is checked against the diameter on every call, on each line.
Sizes the list prices but marks “on request”Only with care
A price exists, so the line prices normally; a flag and an approval path have to be added for the sizes that need confirmation.		The on-request cells are part of the same grid and send the quote to a person while still showing the price.
Stated totals that must equal the list pricesOnly with care
A stated total is a free-entry field; a rule can compare it with the sum of metres times price, but someone has to write and maintain that comparison.		The stated total travels with the quote and is compared with the computed total 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 rep 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.

2Line 1: a 110 mm pipe in PN 12.5 to the NF EN 1452 standard is not in the Lareter price list.
3Line 1: the price list marks this size and PN class as on request; Lareter should confirm availability and price.

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 PVC-U pressure pipe from the Lareter price list: the standard, pressure class and diameter, the joint, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published price list and returns a verdict, every reason, a line-item quote and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 50 lengths of UNI EN ISO 1452 PN 10 pipe, 160 mm, with Power-Lock rubber ring socket, and 30 lengths of UNI EN ISO 1452 PN 10 pipe. The quote states a total of €8,508.00. 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. Line 1: at 20°C this pipe is rated for 10 bar working pressure, but the duty is 12 bar. Line 2: at 20°C this pipe is rated for 10 bar working pressure, but the duty is 12 bar. The quote states a total of €8,508.00; the list prices give €10,907.40.
    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 and against the stated total.
    7. 
      
  7. What this shows: for working pressure that falls as the temperature rises, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the line 1 PN class to PN 16, the line 2 PN class to PN 16 and the stated total to €16,249.20.
    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. All three earlier findings are cleared, and the validator's total, €16,249.20, matches the quote.
    14. 
      
  14. Three problems caught in one call, fixed in one pass, and a clean €16,249.20 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.
