Bookkeeping

Books that run while you sleep.

Categorization that learns from a handful of examples. AP that drafts itself from email. Anomalies surfaced overnight. A close that grades itself by morning.

01 — Categorization that learns

Show it three times. It handles the next three thousand.

Categorize a few transactions yourself. DayZero learns the pattern and auto-handles the rest — quietly, every night. Your team reviews the handful it wasn't sure about, not the hundreds it already knew.

Learns, doesn't ask

Show DayZero three examples of how you categorize your phone bill. It writes the rule itself — no syntax, no setup wizard.

Confidence-graded

High-confidence rules auto-apply. Low-confidence transactions land in your review queue, surfaced with the reason.

Reversible by design

Don't like a rule? Edit it, pause it, or train it differently. The audit trail shows what was auto-categorized and why.

02 — AP Inbox

An invoice arrives. The bill is already drafted.

Vendors send invoices to your DayZero AP email. The agent reads them, pulls vendor, amount, due date, line items, and the expense account — and drafts the bill in pending. By the time someone opens the inbox, the work is done.

1
The email arrives.

From the vendor directly, or forwarded from your inbox.

2
Fields extract themselves.

Vendor, amount, due date, expense account — all read and pulled.

3
The bill is drafted.

Sitting in pending. One click from posted.

Reads PDFs natively

Scanned invoices, structured PDFs, plain-text emails, image-only — the AP agent handles all of them. No OCR setup.

Routes to the right account

Pulls the expense account from your historical categorizations. If it's a known vendor, it picks the same one you would.

You stay in the loop

Nothing posts without approval. Drafts sit in pending, ready for you to review, approve, or send back to the vendor.

03 — Overnight controls

Duplicate payments, caught before the wire goes out.

An agent re-scans the last 30 days every night looking for duplicate bills, rapid-succession payments, and patterns that don't smell right. By morning, you have a triaged list with the evidence and a recommended action.

Runs while you sleep

Nightly re-scan of the last 30 days. By morning, you have a triaged list — no Monday morning fire drill.

Evidence, not just flags

Every anomaly comes with the supporting transactions, the pattern that triggered it, and a recommended action.

Learns from your dismissals

Dismiss a false positive once and DayZero stops surfacing the same pattern. The noise floor gets quieter over time.

04 — Close

A close that grades itself.

DayZero runs a readiness check every night across categorization, reconciliation, anomalies, and variance. By morning you have a score — and the exact list of what's blocking it. No more "I think we're ready."

Score, not status

"Close is in progress" tells you nothing. "Readiness is 66/100, blocked by these 2 things" tells you everything.

Updates every night

Run the close check on day 1 and watch the score climb as work gets done. No big-bang close week.

Auditor-friendly

Every score change is logged with the underlying evidence. Your auditor sees the journey, not just the destination.

For controllers & bookkeeping firms

DayZero gives bookkeeping firms and fractional CFOs a multi-client cockpit with the same agents working across every client. Same rules, same controls, same close scores — at scale.
