Predictika · Excavator rental quotes

An AI sales agent's excavator rental quote, checked before it goes out

An AI sales agent prepares a rental quote for a Cat excavator, with the machine, the attachment, the hydraulic line, the digging depth, the rental term, delivery or collection, the discount and the total the quote states. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the fleet and rental rules and returns a verdict, every reason and the total it computed.

Scope: Cat excavator rental quotes: the compact, crawler and mobile excavators in the fleet, buckets, hydraulic hammers, augers, grabs and tiltrotators, the hydraulic line, digging depth, delivery or collection, rental term, discount and the total the quote states. See everything this validator covers

This validator models Cat excavator rental quotes, not just the scenarios shown below.

  • Machines and attachments — the 305 E CR, 308 E CR, 310 NG, 313 GC, M314 NG, M315 CR and M317F, the attachment each can take, the hammer size that suits each machine's weight, the hydraulic line some machines need and the tiltrotator that the M317F already includes.
  • Job and logistics — the digging depth each machine reaches, delivery or collection on the customer's trailer, travel plates on soft ground and the liability waiver.
  • Term, discount and price — the rate for the rental term, the discount limits, the total stated against the total computed, and a person's review for larger discounts, soft ground without plates and rentals longer than 180 days.

Any excavator rental quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: wheel loaders, dumpers, other rental categories, machine sales and operators. The fleet models, the weights and digging depths of the 310 NG and the M317F, and the tiltrotator included with the M317F follow Zeppelin Rental's public data sheets; the other machine data, the compatibility rules, every rate, fee and discount limit are modeled from comparable rental fleets and are not published by Zeppelin Rental, so every amount here is illustrative.

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
Attachments that depend on the machineOnly with workarounds
A hammer must suit the machine's weight, powered attachments need a hydraulic line on the smaller machines and the M317F already includes a tiltrotator, so a rule must read the machine and the attachment together.		The machine and the attachment are fields of one request and are checked together on every call.
Job limits that depend on the machineOnly with care
Each machine has its own digging depth, and collection needs a trailer that carries the machine's weight.		Each limit is a separate finding, and all of them are returned together.
A rate that changes with the rental termOnly with care
The daily rate steps down at five and at twenty days, and attachments and options are priced by the day.		The term is a field of the request and the price is computed from it on every call.
A stated total that must match the build-upOnly with workarounds
The total chains the machine, the attachment, the options, the term, the discount and transport, so a separate rule must recompute it and compare it with the stated figure.		The stated total is a field of the request and is compared with the computed total on every call.
Referrals for discounts, soft ground and long termsOnly with workarounds
A review depends on the discount, the ground and the rental term together, on top of the blocking rules.		The referrals are separate findings returned together with the blocking ones.

  

  

    
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 job needs 5,300 mm digging depth; the quoted machine reaches 5,198 mm.
2The quoted hydraulic hammer suits carriers from 13,000 to 22,000 kg; this machine weighs 10,200 kg.
3The quoted hydraulic hammer suits carriers from 4,500 to 9,000 kg; this machine weighs 13,700 kg.
4Hammer, auger, grab and tiltrotator need an auxiliary hydraulic line; this machine needs it quoted as an option.
5This machine is not set up for a tiltrotator; choose a larger machine.
6The CAT M317F is rented with its tiltrotator and OQ65 quick-change system already fitted; remove the separate tiltrotator line.
7The customer trailer carries 10,000 kg; the machine weighs 10,200 kg, so it cannot be collected.
8A 15 percent discount is above the 10 percent a branch can give (modeled threshold); a person should approve it.
9A 25 percent discount is above the 20 percent limit (modeled, not company-published).
10The quote states a total of 1,000.00 euros; the validator computes 2,108.50 euros.
11The site has soft ground and the quote has no travel plates; a person should confirm the machine can work there.
12A rental of 200 days is longer than 180 days; a person should agree a long-term contract.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a rental quote for a Cat excavator, with the machine, the attachment, the hydraulic line. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the fleet and rental rules 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 a CAT 305 E CR for 10 days with an H1200 hydraulic hammer, for a job that digs 4,200 millimeters deep. The customer will collect it with a trailer that carries 4,000 kilograms. The rest of the request is on screen. The total stated on the quote is 2,659.00 euros.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with six findings, all in one answer. The job needs 4,200 mm digging depth; the quoted machine reaches 3,600 mm. Hammer, auger, grab and tiltrotator need an auxiliary hydraulic line; this machine needs it quoted as an option. The quoted hydraulic hammer suits carriers from 13,000 to 22,000 kg; this machine weighs 5,000 kg. 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 a stated total that must match the build-up, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the machine to CAT 313 GC, the transport to delivery, the discount to 10 percent and the total stated on the quote to 2,969.00.
    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 quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
