An AI sales agent's e-commerce store subscription quote, checked before it goes out

An AI sales agent prepares a subscription quote for a BigCommerce store: the Core, Growth, Scale or Performance plan, monthly or annual billing, the store's monthly sales (GMV), how much of it runs through open payment providers, extra storefronts, inventory locations and plan-only features. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the plans and prices BigCommerce publishes and returns a verdict, every reason, a line-item quote and the figures it computed.

Scope: BigCommerce store subscriptions at the published list prices: Core, Growth, Scale and Performance plans, monthly or annual billing, GMV limits, extra storefronts, inventory locations, plan-only features, the Open Payment Provider Fee and Scale overage. See everything this validator covers

This validator models store subscription quotes for BigCommerce as published on its pricing and plan-and-pricing-update pages, not just the scenarios shown below.

  • Plans and prices — Core ($39 a month, or $29 billed annually), Growth ($105, or $79), Scale ($399, or $299) and Performance (custom, starting at $1,499 a month billed annually); the quote total is 12 months at list prices.
  • Sales limits and Scale overage — trailing 12-month GMV of up to $30,000 on Core, $100,000 on Growth and $2 million on Scale (above that the store moves up a plan); on Scale, 0.9% of monthly GMV above $33,333. GMV is BigCommerce's own measure, gross order value minus 10%, and the page assumes the same monthly GMV in every month.
  • Storefronts and locations — extra storefronts at $30 (up to 3), $50 (up to 5) and $100 (up to 8) a month on Core, Growth and Scale; inventory locations up to 4, 5 and 8.
  • Payments — the Open Payment Provider Fee of 2.0%, 1.0% and 0.6% on GMV processed through providers outside BigCommerce's embedded list (nothing on embedded providers or on a contracted Performance plan), which is billed to the merchant and must not be passed on to shoppers.
  • Plan-only features — customer groups from Growth, product filtering from Scale, Price Lists and advanced promotions on Performance only, priority support not on Core; Performance is billed annually.
  • Approvals — Performance pricing, the Core phone support add-on and the priority support add-on have no published price and go to a person.

Any BigCommerce store subscription quote that touches these rules is in scope — not only the scenarios pictured here. Not covered: B2B Edition, Feedonomics paid plans, Catalyst and Makeswift, apps and themes, services, card processing rates, taxes, discounts and the terms of a negotiated Performance contract. Prices are the list prices read in October 2026 and may change.

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 plan limit that depends on 12 months of salesOnly with care
The cap on each plan is measured on trailing 12-month GMV, while Scale also prices a monthly threshold; the quote has to carry a derived sales figure and compare it with a different cap for each plan, and keep those caps in step with the pricing page.		The monthly GMV is in the request; the 12-month figure and each plan's cap are computed and compared on every call.
A fee that is a percentage of sales through some payment providersOnly with workarounds
The Open Payment Provider Fee and the Scale overage are percentages of sales, not quote lines, and the rate changes with the plan; a quote has to be given custom fields and formulas to price them, then reconciled with the total.		The rate comes from the plan, the open-provider sales and the Scale overage are inputs, and both are priced in the same pass as the subscription.
A stated total that must equal the list-price totalOnly with care
The stated figure is free text; a rule can compare it with a computed total only after the plan, extra storefronts, overage and fee have been summed.		The total is computed and compared with the stated figure in the same pass as the other rules.
Custom pricing that needs a personOnly with care
Performance has no list price beyond a starting figure, and it is easy for a quote with a price nobody confirmed to go out.		Approval is raised whenever the quote uses Performance, the Core phone add-on or priority support, and the quote cannot be released until it is approved.
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
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 quote has $2,000,004 of trailing 12-month GMV (12 times the monthly GMV); the selected plan covers up to $2,000,000 before BigCommerce moves the store to the next plan.
2The quote adds 4 extra storefronts; the selected plan allows at most 3.
3The quote lists 5 inventory locations; the selected plan allows up to 4.
4The quote routes $6,001 a month through open payment providers, which is more than the $6,000 a month of total GMV.
5The Open Payment Provider Fee is billed to the merchant and must not be passed through to shoppers at checkout.
6Customer groups and segmentation are not included in the Core plan; they start with Growth.
7Product filtering and custom product filtering are included from the Scale plan up, not in Core or Growth.
8Price Lists are listed on the Performance plan only.
9Advanced promotions management is listed on the Performance plan only.
10Performance is custom priced, published as starting at $1,499 a month billed annually, and its storefronts, inventory locations, support and overage terms are contracted; a person should confirm the price.
11Performance is sold on a contract billed annually; monthly billing is not offered.
12Express routing and priority support is not offered on Core; it is an add-on on Growth and Scale.
13Express routing and priority support is an add-on on Growth and Scale and its price is not published; a person should confirm the price.
14Phone support for Core is an add-on that BigCommerce lists as coming soon, with price and timing to be shared separately; a person should confirm availability and price.
15The quote states a 12-month total of $2,387.00; the list prices give $2,388.00.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a subscription quote for a BigCommerce store: the Core, Growth, Scale or Performance plan, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the plans and prices BigCommerce publishes 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 a BigCommerce Scale plan subscription billed annually for a store with $203,333 of monthly GMV, of which $120,000 runs through open payment providers and 8 inventory locations. The quote states a 12-month total of $30,588.00. 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. The quote has $2,439,996 of trailing 12-month GMV (12 times the monthly GMV); the selected plan covers up to $2,000,000 before BigCommerce moves the store to the next plan. Price Lists are listed on the Performance plan only. Advanced promotions management is listed on the Performance plan only.
    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.
    7. 
      
  7. What this shows: for a plan limit that depends on 12 months of sales, 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 performance and the stated 12-month total to $17,988.00.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The validator also returns the line-item quote, on screen.
    13. 
      
  13. The three blocking findings are cleared; one approval remains for a person: Performance pricing to confirm.
    14. 
      
  14. Three problems caught in one call, fixed in one pass, and the corrected quote now goes to a person for approval. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
