Your books. Our responsibility.

Read-only by design

StashGrade connects to QuickBooks through Intuit’s official OAuth flow. You approve the connection on Intuit’s own page, with your QuickBooks login. We never see your password.

The access we request is read-only. StashGrade can read invoices, expenses, and your P&L. It cannot create, edit, or delete anything in your books, and it cannot touch money.

Your books are isolated

Every table that holds customer data is locked to your company at the database level with row-level security. One company can never read another company’s rows. That isolation is enforced by the database itself, not just the application.

Data is encrypted in transit (TLS) and at rest.

What the AI sees and doesn’t

The AI reads aggregated financials: revenue by account, job costs, overhead lines. Analyses run under hard per-company budget caps and rate limits.

We do not sell your data. We do not train public models on your books. Benchmarks, when we publish them, are aggregates that can’t be traced to any one company.

Leaving is one click

Disconnect QuickBooks in settings and our access token is revoked immediately. You can also revoke it from your Intuit account at any time. Your QuickBooks is exactly as you left it.

What StashGrade will never do

Give financial, tax, or legal advice. We show what your books say and the business decision the numbers point to. What you do with that stays between you and your accountant.

Move money, write to your books, or share your numbers with anyone you didn’t approve.
