Overnight bookkeeping

Drop paper in.
Wake up to your books.

You drop paperwork in a folder. Each night our AI reads it, code checks every number, and your live dashboard is current by morning — nothing guessed, nothing typed by you.

Who it's for

The back office you
were about to hire.

Not software you learn — a nightly service that does the desk half of a manager's job. You keep the people work.

Cafés & food shops

Every drink has a recipe, so the room knows what the till sold, what the shelf holds, and what the gap costs. The demo cafe’s espresso crept +14.2% across invoices — $728.71 on what it had already bought — and the room said so before the next order went out.

Contractors

Every invoice and bill tagged to its job, so job margin is a number you check — not a feeling.

CPA & tax practices

Every client's returns, notices, and workpapers filed overnight and findable by searching, originals kept intact.
How it works

Four steps.
You do exactly one.

From a folder of files to a finished dashboard — nobody typing in the middle.

01

Drop files in a folder

We set up a pickup folder on your computer. Scans, PDFs, phone photos, bank exports — any pile, any order.

your only step
02

We pick it up overnight

An encrypted pull collects the day's drop-ins on a schedule tuned to your business. The same reading model goes over every page.

03

Code checks every number

Plain arithmetic does the math and hunts the leaks. Nothing is invented: a figure that does not match its page is held, not guessed.

04

Wake up to the dashboard

Books current when you open up — one view for last night, one for everything. Tap any number for the rows behind it and the page it came from.

every number cites its page
Security, in plain words

Where your paperwork actually goes.

No badges, no jargon — the setup, stated plainly.

Encrypted pickup
Each night your documents travel one encrypted hop — pickup folder to our server, sealed end to end. When the two machines can't reach each other directly, the sealed link is relayed by Tailscale, which carries traffic it cannot open.
One private server
Owned and run by us. Not a data center, not a SaaS platform — your documents are read, stored and computed on this one machine, and nowhere else.
Nothing is sent out to be read or trained on
Your numbers are read by a model on that same machine. Nothing is sent to OpenAI, Anthropic, Google, or any other outside service to be read, processed, or trained on. No analytics vendor, no data broker, no "anonymized aggregate" arrangement.
Encrypted at rest
The server's disk is encrypted, and so is every nightly backup — fourteen nightly generations, each one AES-256 under a key we hold. Today those backups live on that same machine: the second copy kept off it is configured but has never run — the disk is not plugged in yet, and this line will say so until it is. Your business sits in its own folder, separate from every other client's.
Card numbers masked
Card numbers are stripped out of the text we store and out of the filenames we keep, so the books never carry one. Your originals are different: we keep them exactly as you handed them over — unaltered, card number and all — which is what lets us hand them back.
The memo is email
One thing does leave this machine: your 7 a.m. memo, sent as ordinary email, through the mail providers on both ends like any email. It carries figures and short sentences — never your documents.
Leave anytime
Ask and you get your originals back, plus your books as CSV. The FAQ has the timeline. No lock-in.

Straight answers

What owners ask us.

What do I have to install or maintain?
Nothing you manage. Two toggles go on at setup: Tailscale (a private line) on your phone and on the shop computer, and Remote Login on that computer so the nightly pickup can reach the folder. Nothing of ours runs there, and it is two taps to turn off.
Where does my data live?
One private server that we own and run — the security section above says exactly what that means. One location — a private office in New Jersey — and one person, Parth Patel, whose number is at the bottom of this page. The single thing that leaves is your morning memo, which goes out as ordinary email — figures and sentences, never the documents themselves.
What happens when it isn't sure?
It stops. Anything it can't prove from the page lands in your Review tab — resolve it yourself, or we clear the holds together on your review call.
What kinds of paperwork can it read?
Supplier bills, receipts, card-deposit summaries, sales-tax forms, emailed PDFs, spreadsheet exports — as scans, photos, or files. Bank statements and payroll stubs are read and filed today; pulling them apart line by line — every transaction, every stub — is the next build.
Can it really replace the manager I was going to hire?
The desk half, yes: checking invoices, watching prices, drafting orders, tracking stock and waste, reporting the numbers. The floor half — shifts and people — stays human.
Do I have to change how I work?
No. You keep your bank, your accountant, your habits. This sits underneath and does the reading — your accountant gets cleaner books, not a rival.
What if I want to leave?
Your books were never locked in: the records room exports the purchase ledger as a CSV and a monthly close pack for your accountant any day, one click, not just the day you leave. Within ten business days of you asking we return your originals, hand you your books as CSV files, and then delete our copies — working copy first; the encrypted nightly backups it sits inside roll off within 14 days after that. No contract holds your data hostage.
What does it cost?
Nothing, right now. We're early, and founding businesses get Nightbooks free — every module, a review call, no card, no contract, no per-seat fees, no per-document metering. It stays free until we tell you otherwise in writing, with 60 days' notice. When list pricing arrives it is scoped by module — most businesses start with the core and add Finance, Supply Chain, or Insights — and a review call is included at every tier, monthly on the entry tier, weekly on the tiers above it. Book a call and we'll scope your setup.

Fixed scope. Hand us a real box of your paperwork — it runs in one night and you see what it sorted, what it flagged, what it held for your review.
