How it works
The shadow ledger.
Most accounting tools tell you what happened. COSai tells you what really happened — and what it cost you.
What is wrong with QuickBooks alone.
QuickBooks is a record-keeping tool. It records what cleared your bank. It does not know what the job cost your techs in drive time, or what the part actually should have been marked up to, or whether the invoice matched the work order, or whether the deposit matched the invoice.
Your books look fine. Your bank account disagrees. The gap is the profit visibility problem — and QuickBooks was not designed to close it.
COSai is not a replacement. It is the layer that holds context across every system and fills in what QBO alone cannot see.

Shadow Ledger
Every transaction reconciled against context from every connected system
Outputs
Every transaction is reconciled against context from every system that touched it. Discrepancies surface in real time. Your books reflect reality, not paperwork.
The trust dial.
COSai does not go fully autonomous on day one. It starts with everything requiring your approval and advances as the system proves itself in each category. Autonomy is earned, not granted.
You set the threshold. You can always tighten it or loosen it. Every autonomous action is logged with source evidence so your CPA and you can review the full trail.
What COSai actually does — and does not — do on its own.
