Predictika · New-home purchase quotes

An AI sales agent's new-home purchase quote, checked before it goes out

An AI sales agent prepares a purchase quote for a new Toll Brothers home, with a home line and plan size, a home site, options such as MultiGen suites, a basement, garage bays, outdoor living and smart home, Design Studio selections, a sales deposit, a lender, a closing incentive and a loan, and a stated home price. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the home line and quote rules and returns a verdict, every reason and the home price it computed.

Scope: Toll Brothers new-home purchase quotes: home line and plan, home site, MultiGen, outdoor living, smart home, Design Studio selections, deposit, incentive, loan and the home price. See everything this validator covers

This validator models Toll Brothers new-home purchase quotes, not just the scenarios shown below.

  • Home line, plan and home site — the plan sizes each line offers, the buyer age for the Regency active-adult line, the home site size a full MultiGen suite or a pool package needs, and what a townhome or an already built quick move-in home can take.
  • Deposit, lender and loan — the minimum sales deposit, the closing incentive that goes only with the Toll Brothers Mortgage Company and its cap, the loan limit and cash purchases.
  • Approvals and total — the discount, Design Studio selections and home site premium that need a person to approve, and the home price the quote states, which must match the price computed from the quoted items.

Any new-home purchase quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: resale homes, community-specific incentives and mortgage underwriting. The product and option names (Design Studio, MultiGen, Outdoor Living, Smart Home, Regency, Toll Brothers Mortgage Company) are public; the plan sizes, prices and every threshold are modeled from comparable home builders and are not published by Toll Brothers, so all figures are illustrative.

The AI sales agentBuilds the new-home purchase quote from the conversation and says it is ready.
Predictika validatorChecks every rule at once and returns the verdict, each finding, 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
An age requirement for one home lineOnly with care
The Regency line is for buyers aged 55 or older, so the buyer age must be compared with the home line on every quote.		The home line and the buyer age are both in the request, so the check runs on every call.
Options that depend on the home line and on a home that is already builtOnly with care
MultiGen, a third garage bay, a pool package and a finished basement are each unavailable for some lines or for quick move-in homes, so each option needs its own rule.		The line, the options and the quick move-in flag are all in the request, so every dependency is checked on every call.
A site size that depends on the option chosenOnly with workarounds
A full MultiGen suite needs 0.25 acre and a pool package 0.20 acre, so each option needs a different threshold on the same site field.		Each option and the site size are in the request, so each threshold is evaluated on every call.
A closing incentive that depends on the lender and on a share of the priceOnly with workarounds
The incentive is allowed only with the in-house lender and only up to 3 percent of a price that changes with every option, so the cap must be recalculated for every quote.		The lender, the incentive and the computed price are compared on every call and return a block or nothing.
Discount, Design Studio and site premium limits that need approvalOnly with workarounds
Three different shares of the base price each need a different approver, and the base price depends on the line and the plan.		The three amounts are compared with the computed base price on every call, and each returns its own approval request.
A stated home price that must match the computed priceOnly with workarounds
The price is built from the line, plan, options, site premium, selections and discount, so a separate rule must recompute it and compare it with the stated figure.		The stated price is a field of the request and is compared with the computed price on every call, together with every other finding.

  

  

    
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 purchase quote for a new Toll Brothers home, with a home line and plan size. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the home line and quote rules and returns a verdict, every reason and the home price it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a new Toll Brothers Regency active-adult home, Signature plan, on a home site of 0.30 acre with a site premium of 60,000 dollars. It is ready to send. 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. Regency active-adult homes are for buyers aged 55 or older; the buyer is 52. MultiGen options are not offered in the regency active-adult line. A quick move-in home is already built, so a MultiGen suite, a pool package or a finished basement cannot be added. 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 and against the stated total.
    7. 
      
  7. What this shows: for options that depend on the home line and on a home that is already built, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the buyer age to 58, the MultiGen to none, the basement to unfinished, the sales deposit to $25,000 and the home price stated on the quote to $1,123,000. Two more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All six earlier findings are cleared.
    13. 
      
  13. Six problems caught in one call, fixed in one pass, and a clean $1,123,000 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.
