Diligence-ready books are financial records clean and current enough to hold up the moment a real buyer, investor, or auditor asks to see them, not just good enough for the founder's own internal use.
The bar is different from what most early-stage companies run day to day. Diligence-ready means monthly closes with no backlog, accounts reconciled to actual bank and card statements, revenue recognized on an accrual basis, and a cap table that matches what's actually been issued. The kind of books that answer a data-room request in days instead of weeks.
The gap between books that work fine internally and books that hold up under someone else's diligence team is usually invisible until it matters. Better to close it before a term sheet or LOI sets the clock running than to find it during the diligence period itself, when there's no time left to fix it calmly.
