Before you connect
Questions about BNPL Comparator.
The practical details behind the request, access and result.
How does the BNPL Financial Comparator find hidden fees?
It analyzes the terms of your 'pay later' plan to see what happens if you miss a payment. It then calculates the real interest rate you'd pay based on those potential fees.
Can I use this to see how much interest my credit card will charge?
Yes. You can tell your agent the amount of your purchase and your card's APR. It will calculate exactly how much extra you'll pay if you carry that balance for a specific amount of time.
Will the BNPL Financial Comparator help me find the best discount?
It compares your cash or debit options against other plans. It calculates the final price for cash payments so you can see if a rebate or discount is actually the cheapest way to pay.
Is this capability good for large purchases?
It's perfect for big-ticket items where the difference between 0% interest and a high APR can be hundreds of dollars. It helps you see the long-term cost of different financing options.
Can I get a summary of all my payment options at once?
Yes. You can ask your agent to compare multiple methods, like a BNPL plan, a credit card, and a cash discount, all in one view. It will flag the cheapest option and highlight any high-interest risks.
How does the capability calculate the true APR for BNPL?
The calculate_bnpl_financials capability incorporates any provided late fees into the total cost of the installments, then annualizes that extra cost to show you the real interest rate you are paying.
Can I compare different credit card interest rates?
Yes, by using calculate_credit_card_impact, you can input various annual interest rates and durations to see exactly how much interest will accumulate on a specific purchase amount.
Does the capability account for cash discounts?
Absolutely. The evaluate_cash_benefit capability allows you to input potential discount percentages to see how much you would save by paying with cash or debit instead of financing.
