What DayZero is
DayZero is an accounting and finance firm that uses software it built to handle company finance either end to end or alongside a customer’s team. Its products share a double-entry ledger covering bookkeeping, reconciliation, invoicing, bills, reporting, cash forecasts, demand planning, inventory, and client and practice management. Purpose-built accounting agents categorize transactions, match bank activity, draft entries, and flag anomalies, with logged actions available for review. Prompt-based AI reporting can produce financial reports and commentary, exporting to PDF, PowerPoint, or live links. Live connectors include Plaid, Stripe, Square, Shopify, Ramp, and Slack; QuickBooks Online and Xero are listed for one-time migration. Developer access includes a REST API, signed webhooks, and an MCP server with dry-run previews, approval gates, and audit trails. DayZero also offers managed close, capital readiness, due-diligence support, CFO advisory, integration engineering, and firm enablement.
