Qisti (قسطي) is a Saudi web app for car dealers who sell on direct installments. Import your existing Excel ledger as-is (name, phone, total, paid, remaining, monthly installment; no ID or plate needed), see who paid and who is late this month, and send a one-tap WhatsApp reminder to each late buyer. Record payments when the bank transfer arrives; export to Excel. Arabic RTL, works on phone. Not a lender, never handles money, 0% commission. Free up to 5 buyers.
