# Yulo > Contract-to-ledger revenue accounting infrastructure for SaaS and contract businesses. Yulo converts contract and billing-source facts into deterministic revenue accounting outputs with full audit traceability and explainable IFRS 15 rationale. ## Core product facts - AI extracts facts; deterministic rules perform accounting. - Outputs include billing schedules, revenue schedules, deferred revenue and journal entries. - Material numbers are explainable at three levels: source evidence, calculation, and accounting rationale. - The accounting rationale explains why a treatment is appropriate under IFRS 15 and the applicable policy, not only where a number came from. - Audit traceability links accounting output back toward schedules, contract components, extracted fields or source rows, clauses and source documents. - Yulo is positioned as revenue accounting infrastructure between commercial source systems and ERP/general ledger systems. ## Canonical flow Source evidence -> extraction -> normalized contract -> deterministic AccountingRun -> schedules -> deferred revenue / journal entries -> audit trace -> IFRS explanation. ## Primary pages - Homepage: https://getyulo.com/ - Product facts: https://getyulo.com/product-facts/ ## Contact - Demo and product enquiries: info@getyulo.com
