BillBuffer

BillBuffer is a mobile + web app that creates a realistic “safe-to-spend” number by reserving money for upcoming bills and subscriptions automatically. Users connect their bank account(s), and the app detects recurring charges, pay cycles, and irregular bill timing (like quarterly insurance). It then builds a rolling buffer plan: how much must stay untouched today to avoid a negative balance later. You can set a target buffer (e.g., $300) and BillBuffer recommends weekly micro-moves to reach it without breaking your lifestyle. It also flags risky days when multiple bills cluster, suggests moving due dates (where possible), and warns when a new subscription threatens your buffer. This isn’t a full budgeting app; it’s a guardrail that prevents “I thought I had money” mistakes. Monetization: freemium with paid features like multi-bank, advanced forecasting, and bill negotiation partners.
