How we bill by the day: the service-day model
· 10 min read
Billing at Fibe runs on a unit we call the service-day. A Marquee is either funded for today or it isn't. Every day, for every funded environment, a small charge is taken from the player's Wallet and the Marquee's paid-through time is pushed to the end of the current day. There is no monthly subscription to reason about, no proration math, no surprise cliff at the end of a cycle — just one question, asked once a day, forever: did you pay for today?
This post is about why we chose that shape, how the daily charge keeps an environment running, and the single design rule underneath it that keeps every part of the billing lifecycle agreeing on what "today" actually means.
