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.

Every engagement is scoped to your stack and your close — we name the number on the first call.

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?: Yes. DayZero offers a direct Xero integration that imports your chart of accounts, transactions, and balances. From QuickBooks and 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?: Every engagement is scoped — to your stack, your volume, and what you need shipped. We name the number on the first call, before the pilot starts. No rate cards, no per-seat math.
Do I need an accountant to use DayZero?: You get ours. Every engagement pairs DayZero accountants and engineers with your team — we run the books, or we stand behind your team while they do.
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.
