How We Work

The pilot: five days on your real books — bank feeds connected, history reconciled, and a first close review on day five.
The deployment: our engineers build the integrations your stack needs while our accountants run the first closes with your team.
The partnership: we run the books, or your team runs them on the platform with us behind it.

The pilot is free. Self-Directed is $100 a month after a 30-day free trial, and Fully Managed starts at $300 a month.

Frequently Asked Questions

What is DayZero?: DayZero is a consulting firm that handles every side of company finance — accounting and the close, AP/AR, inventory and landed COGS, demand planning, cash forecasting, loan packages and debt schedules, reporting — delivered on software we built ourselves. Our accountants run the work end-to-end, or stand behind your team while they run it. Our engineers work directly with you: they wire the platform into your stack and build the features your operation needs.
How does the AI work? Is it accurate?: DayZero uses purpose-built AI agents trained specifically for accounting tasks. Every action is logged and reviewable with full source attribution.
Can I migrate from QuickBooks or Xero, or keep QuickBooks?: Yes. DayZero imports your chart of accounts, transactions, and balances from QuickBooks Online or Xero. If your accountant stays on QuickBooks Online, keep it connected and DayZero syncs changes both ways after the import. From other platforms you can migrate via CSV import, and our team can assist with larger migrations.
Is my data secure?: DayZero uses AES-256 encryption at rest and TLS 1.3 in transit. SOC 2 Type II certification in progress. Full audit trails for all AI actions.
How does pricing work?: Self-Directed is $100 a month after a 30-day free trial, Fully Managed starts at $300 a month, and accounting firms pay per client. Every engagement can start with a free five-day pilot.
Do I need an accountant to use DayZero?: Not on Self-Directed: you run the books yourself, with AI doing the busywork. Fully Managed includes a dedicated DayZero accountant who runs them for you.
What integrations are supported?: Plaid (banking), Stripe (payments), Shopify (e-commerce), Square (POS), Ramp (corporate cards), Slack (notifications), plus QuickBooks Online and Xero migrations — with NetSuite, Sage Intacct, and more on the roadmap.
How is DayZero different from QuickBooks, Xero, or Bench?: DayZero is AI-native from the ground up — not AI bolted on after the fact. It gives you real-time access and full control with 576 specialized AI tools.
