200 — The products

Eleven products. One Ledger.

Every product reads and writes the Ledger — one double-entry core under books, billing, cash, inventory, reporting, and practice. Add one product, or run the stack.

300 — CFO advisory

CFO-level intelligence, without the CFO price tag.

DayZero continuously analyzes your books to surface the metrics, insights, and recommendations that used to require a full-time finance team. Scorecards, variance narratives, lending prep, and cash forecasting — generated automatically from your live data.

Financial Scorecards

Real-time KPI dashboards with revenue, margins, burn rate, and runway — auto-generated from your books.

Variance Analysis

AI explains every material variance: what changed, why, and whether it needs attention.

Lending & Fundraise Prep

Generate loan packages, debt schedules, and investor-ready financials in seconds.

Cash Flow Forecasting

13-week rolling forecasts built from actuals, AR aging, and AP schedules — refreshed as your data syncs.

400 — The operating system

The operating system for company money.

For Scaling Businesses

We run your back office on one Ledger — books to inventory to payroll sync — and hand you a close that lands on time. Whether you're bootstrapped or venture-backed, services or product-based.

Invoicing & Payments

Create invoices, accept online payments via Stripe, and auto-reconcile revenue — all in one place.

Inventory & E-Commerce

Track stock, manage purchase orders, and sync products across Shopify and Square automatically.

Payroll, Expenses & Banking

Sync payroll, expenses from Ramp, and bank feeds from Plaid — all reconciled by AI.

Reporting & Budgets

P&L, balance sheet, cash flow, budgets, and custom reports on demand — reviewed by the accountants who close your month.

For Advisory Firms

We deploy our platform and our close playbooks across your book of business — every client on the same Ledger, every close on the same playbook, our team alongside yours.

Multi-Client Management

Manage all your clients from a single dashboard. Switch between books instantly with full isolation.

Client Portal

Give each client real-time visibility into their financials, documents, and action items.

Cross-Client Reporting

Run reports and workflows across your entire book of business from one screen.

AI Workflows

Deploy reusable workflows — monthly close, tax prep, onboarding — across every client at once.

500 — The shift

The close, posted as a T-account.

600 — Questions

Asked, answered.

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 — when something's missing, it gets built, not filed as a ticket. Underneath it all is one double-entry ledger, so every product reads and writes the same numbers.
DayZero uses purpose-built AI agents trained specifically for accounting tasks — not a general-purpose chatbot pointed at your books. Every agent action is logged and reviewable. You set confidence thresholds that determine what gets auto-applied vs. what comes to you for review. Every entry includes full source attribution so you can verify any decision.
Yes. DayZero is built for auditability, not blind trust. Every AI action records its inputs, the source documents it referenced, the rule or match logic it applied, and a confidence score — all captured in an immutable audit trail you can review or export. You set confidence thresholds so anything uncertain routes to a human for review, and nothing is hidden. It's designed to satisfy your auditors and give your CFO the traceability they need to sign off.
Yes. DayZero has direct migration connectors for both QuickBooks Online and Xero — connect via OAuth and DayZero imports your chart of accounts, customers, vendors, items, transactions, and balances, finishing with an opening-balance journal entry and a trial-balance QA report. From other platforms you can migrate via CSV import, and our team can assist with larger migrations.
Absolutely. DayZero encrypts everything — AES-256 at rest · TLS 1.3 in transit. SOC 2 Type II in progress, target Q1 2027 with a third-party auditor; in the meantime we operate against the SOC 2 control framework, enforce role-based access controls, and maintain a full audit trail for every AI action. We never train on your proprietary data.
Every engagement is scoped. We look at your stack, your volume, and what the close actually requires, then we name the number on the first call — no rate card, no per-seat math, no surprise overages. Most engagements start with a five-day guided pilot so both sides know exactly what they're signing up for. See how we work for the full picture.
You get ours. Most engagements are run end-to-end by our accountants on our platform — categorization, reconciliation, close, and reporting handled for you. If you already have a team or a firm you like, we deploy the platform into your stack and they run it with our support.
DayZero integrates with Plaid (banking), Stripe (payments), Shopify, Square, Ramp, HubSpot, Slack, and more, plus direct migration connectors for QuickBooks Online and Xero. ERP connectors for NetSuite and Sage Intacct plus Amazon are on the roadmap. You can request any integration and it directly shapes what we build next.
We're a firm, not a subscription. Accountants and engineers who deploy our own platform into your stack and then own the outcome — clean books, a close that lands on time, a cap table you can defend, numbers ready for the raise. QuickBooks and Xero sell you software and leave the work to you. Bench and Pilot sell you a service and keep the software to themselves. We do both, which is why you keep real-time access and full control of your books while we run them.
