Why upfront cash is not upfront revenue
Revenue follows delivery, not collection. Under the IFRS-based reporting most UAE companies use, a subscription is a service delivered over time, so income is recognised as each month of access passes. The cash you collected in advance sits on the balance sheet as a liability called deferred revenue (sometimes unearned revenue or contract liability) until you deliver.
Our view: early-stage SaaS teams should adopt monthly recognition from the first paying customer. Retrofitting it after a funding round means re-opening a year of invoices, and the due diligence team will ask for exactly that schedule anyway.
