InstallPay: Buy Now, Pay Later

InstallPay: Buy Now, Pay Later App UI Kit InstallPay is a BNPL app UI kit I designed and released as a standalone product. It covers 50+ screens and 80+ components across onboarding, shopping, card management, orders, payments, notifications, and account settings, all sitting on one design system so a team can ship a working fintech product without starting from zero.

Every screen is built around real BNPL behaviour: splitting a purchase into four interest-free payments, tracking total owed against what's due in 30 and 60 days, adding and switching between credit and debit cards, browsing brands, and setting a 4-digit PIN for quick login. Components use variables and auto layout, so colour, type, and spacing update across the whole file in a single pass instead of screen by screen.

I made this because most fintech kits stop at pretty screens and fall apart the moment you need a real payment schedule or a card state that isn't the happy path. This one is meant to be picked up and built on.

It's available on Figma Community and Lemon Squeezy. #UIDesign #UXDesign #MobileAppDesign #DesignSystems #Figma #Fintech #ProductDesign
