BNPL liquidity calculator
Cash-out quotes were calculated by hand against Tamara and Tabby tables. We shipped a public calculator that turns product value, down payment, and provider into a WhatsApp-ready order.
The situation
The business converts installment purchases into immediate cash. Staff were quoting transfer amounts from a price sheet.
The constraint
Every quote must show product value, transfer amount, first installment, monthly installment, and tenure before the customer sends WhatsApp.
What we refused
A static price image. A spreadsheet emailed after the lead arrived.
What we shipped
Interactive pricing table, Tamara / Tabby switch, down-payment toggle, computed quote, and WhatsApp order payload.
Stack, on purpose
TypeScript, Next.js, deterministic pricing rules. The quote is computed in the page, not generated.
What changed
The customer sees the same number the operator will honor before the chat starts.
What we would do next
Persist quotes as tickets so operations can reconcile payouts without retyping the form.
