Predictika · T-Mobile for Business account quotes

An AI sales agent's business account quote, checked before it goes out

An AI sales agent prepares a monthly quote for a fictional business customer on T-Mobile for Business phone lines: plan, line count, devices, credit tier, eligibility program, discounts, roaming, promos and the monthly total it expects. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of the plan, credit, program, discount, device and promo rules, compares the total the agent states with the one it computes, and returns a verdict with every reason.

Scope: T-Mobile for Business CoreMobile, ProMobile and SuperMobile account quotes: line pricing, credit tiers, eligibility programs, discount authority, hotspot and roaming, device financing, promos and the monthly total. See everything this validator covers

This validator models T-Mobile for Business phone-line quotes in US dollars per month, not just the scenarios shown below.

  • Plans, lines and credit — CoreMobile, ProMobile and SuperMobile pricing by line count, the AutoPay credit, the telco recovery fee per line, lines allowed by credit tier, equipment credit limits, credit approval for large financed amounts, the Tier 3 deposit and paying devices in full.
  • Programs and discounts — first responder, military and 55+ discounts with verification, line limits and the age rule, the rule against combining them with a negotiated discount, and negotiated discount authority by line count.
  • Hotspot, roaming, devices and promos — hotspot allowance by plan, international coverage and add-ons, new-line and switcher device promos with their plan, financing, port-in and trade-in conditions, line-item pricing, and a check that the monthly total the agent states matches the validator total.

Any T-Mobile for Business phone-line quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: consumer, prepaid, home-internet and government plans, taxes, real credit checks and real contract terms. Prices for the three plans and the telco recovery fee follow the public T-Mobile site; credit limits, program terms, discount authority, most device prices and promo values are estimates for demonstration.

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
Credit tiers that limit both the number of lines and the financed equipmentOnly with care
Each tier has a line cap and an equipment limit, and the financed amount is lines times the device price, so the check depends on two fields and a calculation.		The tier limits and the financed amount are computed once and checked together with the other rules.
Eligibility programs that cannot be stacked with a negotiated discountOnly with workarounds
A program discount, a verification step, a line limit and an age rule all interact with a separate negotiated discount, and the combination has to be refused rather than silently priced.		All program and discount conditions are checked together, so a quote that breaks two of them returns both findings.
Discount authority that changes with the number of linesOnly with care
A rep limit, a manager limit and a minimum line count for the higher band are separate thresholds that must agree.		Requested discount and line count are checked together, with approval and block bands applied by account size.
Device promos that depend on plan, financing, port-ins and trade-inOnly with workarounds
The promo is valid only when the plan allows it, the device is financed, every promo line ports in and a trade-in is present: four conditions across four fields, and fixing the financing can break the promo.		All four conditions are checked together and each failure comes back with its reason.
Hotspot and roaming needs against the plan and its add-onsOnly with care
Whether an add-on is redundant or a need is covered depends on the level each plan includes, so it needs a comparison per plan.		The plan level and the add-on level are compared on every call.
Pricing with discounts, AutoPay, installments and promo credits that must add upOnly with care
The monthly total combines tiered plan prices, percent discounts, a capped AutoPay credit, device installments and promo credits, and each line must reconcile to the total.		Line items are produced by the same calculation as the total, so they always reconcile.
The monthly total the agent statesOnly with workarounds
A rule can compare a stated figure with a calculated one only if the stated figure is a field on the quote, and the calculation has to include every credit and discount.		The stated monthly total travels with the quote and is compared with the computed one on every call; a difference blocks the quote.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved, 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
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.

    
1$9,600 financed on installments is above $6,000 and needs credit approval.
210 percent negotiated discount is above the 5 percent a rep can give; sales manager approval up to 15 percent.
3$7,439.92 financed on installments is above $6,000 and needs credit approval.
410 lines exceed the 8 lines allowed for credit Tier 2.
5$2,789.97 of devices on installments exceeds the $1,500 equipment credit limit for Tier 3; pay some devices in full or reduce lines.
6The military discount needs eligibility verification before it can be quoted.
73 lines exceed the line limit of the 55+ program (12 for first responder and military, 2 for 55+).
8The 55+ program needs an account holder aged 55 or older; holder age is 50.
914 lines exceed the line limit of the first-responder program (12 for first responder and military, 2 for 55+).
10Eligibility program discounts cannot be combined with a negotiated discount.
11A 8 percent negotiated discount on 6 lines is beyond authority (max 15 percent, above 5 percent needs 10 or more lines).
1220 GB of high-speed hotspot needed but CoreMobile includes 5 GB.
13International need level 2 is not covered by CoreMobile and the selected add-on.
14The Global Plus add-on is already included in SuperMobile; remove it.
15Device promotions are not available on CoreMobile; they need ProMobile or SuperMobile.
16Device promo credits are paid only on a new device financed on a 24-month equipment installment plan.
17The switcher promo is claimed on 4 lines but only 1 lines port in.
18The switcher promo requires an eligible trade-in device.
198 percent negotiated discount is above the 5 percent a rep can give; sales manager approval up to 15 percent.
20Stated monthly total does not match: the agent stated USD 310.18; the validator computes USD 344.64.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a monthly quote for a fictional business customer on T-Mobile for Business phone lines: plan, line count, devices, and more. Before the quote goes out, the agent sends it to Predictika, which checks it against a declarative model of the plan, credit, program, discount, device and promo rules, compares the total the agent states with the one it computes, and returns a verdict with every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 14 CoreMobile lines, each with an Apple iPhone 17 on a 24-month installment plan, on Tier 2 business credit. 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 eleven findings and one approval, all in one answer. 14 lines exceed the 8 lines allowed for credit Tier 2. $13,019.86 of devices on installments exceeds the $4,000 equipment credit limit for Tier 2; pay some devices in full or reduce lines. The first-responder discount needs eligibility verification before it can be quoted. The other eight are on screen.
    6. 
      
  6. The validator returned eleven blocking findings and one approval 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 credit tiers that limit both the number of lines and the financed equipment, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the plan to SuperMobile, the lines to 8, the device to T-Mobile REVVL 7 5G, the verification status to verified and the monthly total stated on the quote to 354.67. Two more changes are on screen. It removes the negotiated discount.
    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 T-Mobile REVVL 7 5G and Telco recovery fee; the other three lines are on screen.
    13. 
      
  13. All twelve earlier findings are cleared, and the validator's total, $354.67, matches the quote.
    14. 
      
  14. Twelve 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.
    15.
