Predictika · Business banking quotes
An AI sales agent prepares a monthly charges quote for a small business opening the Santander UK Business Current Account (Classic): the monthly fee and any no-fee offer, cash and cheque volumes, and an optional overdraft. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published tariff and conditions and returns a verdict, every reason, a line-item quote and the figures it computed.
This validator models monthly charges quotes for the Business Current Account (Classic) as published on the Santander UK page for that account (read October 5, 2026), not just the scenarios shown below.
Any quote for this account that touches these rules is in scope — not only the scenarios pictured here. Not covered: other Santander business accounts, CHAPS, foreign currency and other payments charges, change-giving, partner offers, the credit assessment itself, interest on borrowing and taxes. Assumptions: cash amounts are entered in whole hundreds of pounds because the tariff prices cash per £100; the overdraft arrangement fee is shown as an annual figure and is not part of the monthly total; the switcher offer is taken as stated, because the quote has no way to confirm where the business switched from.

What this means
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 caught | Typical rules-based CPQ | Predictika |
|---|---|---|
| A fee that is waived for the first 12 months only under conditions | Only with care A rule per offer for the month count, the trading age and the first-account condition; it works, but the conditions sit on different fields and a quote can carry the offer after it has ended. | The offer, the month of the account and the start-up conditions are evaluated together and the fee the quote should show is computed from them. |
| Charges that apply only above an allowance | Only with care A price rule for the first £1,000 at cash machines and another for the excess; it works, but each volume has its own unit, and the arithmetic has to be kept in step with the tariff. | The allowance is subtracted, each volume is priced, and the lines are added into one total. |
| A stated total that has to match the computed total | Only with care The rep types the total; a validation rule can compare it, but only if every charge rule has already run. | The stated total is compared with the computed total in the same pass as every other rule. |
| An overdraft that is subject to acceptance | Only with workarounds There is no rule that decides acceptance, so the quote usually goes out and the approval is left to a later step. | The overdraft range is checked and the request is held for a person to confirm. |
| Every problem returned in one answer | Only 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. |
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 | The quote applies a no-monthly-fee offer in month 13 of the account; the offer covers the first 12 months. |
| 2 | The start-up offer is for a business in its first year of trading; the quote shows 13 months of trading. |
| 3 | The start-up offer is for a first business current account with the bank; this is not the business first account. |
| 4 | The quote states monthly charges of £89.74; the published tariff gives £79.75. |
| 5 | The quote states monthly charges of £89.73; the published tariff gives £89.74. |
| 6 | The quote states monthly charges of £96.74; the published tariff gives £89.74. |
| 7 | An overdraft is subject to acceptance by the bank, so a person should confirm it. |
| 8 | An overdraft of £400 is outside the £500 to £25,000 range. |
| 9 | An overdraft of £25,100 is outside the £500 to £25,000 range. |
| 10 | The account requires no bankruptcy declarations; the applicant has one. |
| 11 | The account requires no disqualified director status within the last 6 years; the applicant has one. |
| 12 | The account requires no Individual Voluntary Arrangement history; the applicant has one. |
| 13 | The quote states monthly charges of £0.00; the published tariff gives £89.74. |
| 14 | The quote applies a no-monthly-fee offer in month 14 of the account; the offer covers the first 12 months. |
| 15 | The start-up offer is for a business in its first year of trading; the quote shows 20 months of trading. |
| 16 | An overdraft of £30,000 is outside the £500 to £25,000 range. |
| 17 | The quote states monthly charges of £1.00; the published tariff gives £89.74. |
