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 its own readiness.

The books aren't hard. They're endless.

Nothing in a month of bookkeeping requires a second opinion. It just requires someone to sit there and do it — every day, forever. That is the part DayZero takes.

The volume never stops

Thousands of transactions a month, and the same handful of merchants over and over. You are not solving a hard problem — you are re-solving an easy one, forever.

The work arrives as email

Invoices land in an inbox, get forwarded, get lost, get paid twice. The system of record is a thread nobody owns.

Nobody knows if you can close

Close week is a scramble to find out what is missing — which is exactly the thing you should have known on day 3.

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, in the background. Your team reviews the handful it wasn't sure about, not the thousands 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.

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 — a nightly re-scan of the last 30 days, so there is no Monday morning fire drill
Evidence, not just flags — the supporting transactions, the pattern that triggered it, and a recommended action
Learns from your dismissals — clear a false positive once and the same pattern stops surfacing

04 — Close

A close that grades itself.

DayZero runs a readiness check across categorization, reconciliation, anomalies, and variance. You get a score — and the exact list of what's blocking it. No more “I think we're ready.”

Score, not status — “66/100, blocked by these 2 things” beats “close is in progress”
Always current — run the check on day 1 and the score recomputes as work gets done. No big-bang close week
Auditor-friendly — every score change is logged with the underlying evidence

Getting started

Three steps, then it's running.

Onboarding is a migration, not an implementation project. The agents start from the history you already have.

1
Connect and migrate

Bank feeds via Plaid, plus direct migration connectors for QuickBooks Online and Xero — chart of accounts, vendors, and history come with you.

2
It learns your history

Your existing categorizations become rules on day one. There is no rule syntax to learn and no setup wizard to sit through.

3
You review the exceptions

Low-confidence transactions, drafted bills, and overnight anomalies — the short list, not the long one.
