The simple version

This is Luca. And this is not.

Luca is

  • One accountant who closes your books and reads them forward.
  • A live layer over the QuickBooks you already have.
  • Bookkeeping and a fractional CFO, in one flat fee.
  • Closed by the 5th, and open to you any hour.
  • Built and run by the person who did the work.

Luca is not

  • A SaaS you have to run yourself.
  • A CPA firm. Your tax preparer still files.
  • A rotating team of juniors.
  • A report that lands weeks after the month.
  • Another tool built by people who never closed a month.
Adriel Kornschuh, the accountant behind Luca

Run by Adriel Kornschuh.

Founder of Luca. Accountant and fractional CFO.

Works US Eastern hours, on US businesses.

Answers in English and in Spanish.

One accountant on your file, not a junior rotating through it.

The AI here is not off the shelf. It runs the method I used by hand for years, written down as rules it has to follow. The person who closes your books writes your report and answers your questions, on US Eastern hours, and covering both the bookkeeping and the CFO work is why it is one flat fee, not two separate invoices.

  • Cleanups and chart of accounts rebuilds: files that had grown for years until nobody could read a report from them.
  • Intuit QuickBooks ProAdvisor certified, the credential Intuit itself issues for QuickBooks Online expertise.
  • Board packages prepared for an M&A process, written for the people on the other side of the table.
  • Books for venture-backed US technology companies, including AI startups, where the numbers had to hold up to investors.
  • Client names stay out of this page. Ask in the diagnostic and the specifics get discussed there.

Luca is not a US CPA firm: your tax preparer keeps filing, and gets clean books from me in January instead of a shoebox in March.

A first group of ten this year

The first group is deliberately small, and that is the reason to come in now.

You will not find a wall of logos or borrowed testimonials here. What being in the first group buys you instead:

1

One accountant owning the work. The same accountant closes the month, writes the commentary and answers in the thread.

2

The first intake closes at ten companies. One accountant signs every close, so the group stays small on purpose. Founding terms for those ten: the price you sign is the price you keep for as long as you stay, and the books cleanup runs at half price. When the ten are in, the intake closes.

3

You can audit the work, not trust it. The checklist, the reasoning on every entry and the age of every question are all visible in the demo, right now.

4

Nothing to lose by looking. Demos need no login, the diagnostic is free, and you can leave any month.

And if your accountant is unavailable? The work is built to survive that. Your books live in your own QuickBooks, every decision is written down in the portal, and every report stays exportable. A successor accountant steps into a documented file.

Twenty minutes, and you know if it fits.

A call with Adriel to look at how your books run today. After that, everything happens in writing.

Book 20 min with Adriel

Four steps, then Luca runs your books.

Plug and play on the QuickBooks you already have. Nothing to install, nothing to migrate.

  1. 01Connect QuickBooksRead-only access, three minutes, no card. The subscription stays in your name.
  2. 02Questions arrive rankedThe ones that move the number first, each with its own age and what it is holding up.
  3. 03You answer in one lineWhatever you know. No chart of accounts to pick from, no form to fill out.
  4. 04Reviewed, then postedThe AI drafts the categorization, your accountant checks it, and it posts to your own file. Nothing reaches QuickBooks without a person. Books close by the 5th, every month.

And if a date ever slips, you hear it from me before the date, with the reason and the new one. Never after, and never from silence. That is the part most providers get wrong, and it is the part you should judge me on.

Then every month, like this. Sample data.

This is the product. Drive it.

This week's pulse

What your accountant would flag this week, straight from the books.

$21,228 is stuck in invoices over 60 days old

7 invoices have been out more than two months. Collection odds drop fast from here. Worth a personal nudge this week; reply here and we send the reminders for you.

Cash is trending up: $280,258 in sight

From $210,958 today to $280,258 in eight weeks if invoices and bills land on their due dates. A good stretch to decide what that surplus should do: taxes set aside, a cushion, or reinvestment. Happy to run the numbers on any of the three.

Your September 2026 report
Revenue$297,481
Expenses$222,440
Net income$75,041
Cash at month end$183,596
From your accountant

September brought in $297,481 between retainers and project work, against $222,440 of costs, leaving $75,041 of net income. The recurring base held steady, which is the part that matters most for planning. The number worth your attention is receivables. There is $67,500 sitting past due, most of it with two clients, and that is why cash moved less than the month on paper suggests. Chasing those two would turn a good month on the income statement into a good month in the bank.

A real person keeps these books. A question, an idea, something that looks off: write me directly and I answer personally.

Ask Luca

In your own portal this answers anything about your books. Here, try one of the questions below.

Northwind Studio's books. The sections, the cash table and the written report are the components the product renders, not a picture of them.

Open the whole thing

Open the full demo portal. No login, no email gate. It installs as an app on your iPhone and Mac, and the portal shows you how the first time you sign in.

What usually needs fixing

Two problems almost every small business has, and how each one gets solved.

None of these are edge cases. Each is a specific way the books quietly go wrong, and exactly how Luca handles it.

The number that lied

The bank balance said the hire was fine. It was not. That number still counted a payroll run, two vendor checks nobody had cashed, and the sales tax due in three weeks. The books would mention all of it eventually, in next month's close.

A weekly eight-week forecast subtracts what is already committed before you ever see the number, so the balance stops lying and a yes is a yes you can afford.

The 11 pm transfer

Payroll clears Friday. Thursday at eleven you are moving money between accounts and texting a client to please, finally, pay the invoice from two months ago, because the only warning you got was this morning's balance.

Receivables are tracked to their due dates and the forecast flags the tight week two months out, so you move money on a plan instead of at midnight.

Priced in public

One flat fee. Four sizes. All of it on this page.

The whole list is public, so you see the price before you talk to anyone. The 20-minute call is to understand your business and confirm the size, not to find out what it costs.

Book 20 min with Adriel

Running several entities, or need board and lender packages on demand? CFO scope starts at $5,000/mo, and the exact number comes from the same free diagnostic. On the Partner plan, see a sample board deck.

Starter assumes up to about 100 bank and card transactions a month and the other sizes up to about 500; above that, the free diagnostic reads the file and prices the work first, so nobody meets a surprise in month two. A one-time cleanup, if you need one, is quoted from the same diagnostic and typically runs $500 to $1,000 on Starter and $1,500 to $2,500 on the other sizes; the ten founding companies pay half of that.

Bought separately

$2,800 to $6,600

a month. A part-time bookkeeper plus a fractional CFO, on two separate invoices.

One person, one number

$1,200 to $3,000

a month, flat, for the books and the CFO work together. The same person closes, writes and answers.

Where Luca is the wrong fit

  • Pre-revenue, with nothing to book yetThere is nothing to close yet. When the first real months come in, Starter is the size built for them.
  • Not on QuickBooks OnlineThe whole service runs inside your QBO file, so there is no version of this without it.
  • Looking for tax filing onlyFiling stays with your CPA. Luca closes the books your CPA files from.
  • Wanting a bookkeeper at the next deskEverything here happens in writing, in the portal, on US Eastern hours.

Weighing it against doing it yourself, a firm or software? The honest comparison, with what each one charges

Tax season

January arrives with a package, not a scramble.

Luca does not file your taxes; your tax preparer does, and gets the easiest January of their career. Every client gets a year-end tax package built from books that were closed month by month, and the preparer can ask anything about it. The back and forth is included, not billed.

The year, closed

Full-year profit and loss and the year-end balance sheet, from months that were verified when they happened, not reconstructed in March.

1099s, ready

Every vendor over the $600 threshold with their W-9 status, chased during the year instead of in a January panic.

Notes for the preparer

How owner transactions, assets and meals were booked, in writing, so classification questions are answered before they are asked.

Open the sample year-end package (demo data)

Rather not call yet?

Three ways to start without talking to anyone: a thirty-second self-check, the free diagnostic of your books, or a short note that Adriel reads himself.

Before you connect anything

Four questions tell you a lot.

Thirty seconds, nothing to connect, no email asked. If the grade surprises you, the free diagnostic reads the real file and gives you the true number.

Free diagnostic · 3 minutes

Find out what shape your books are in. It costs nothing.

Luca reads your QuickBooks read-only, grades the books 0 to 100, and hands you an ordered cleanup plan. If your books are fine, the diagnostic says so.

What happens next: a one-click sign-in lands in your email, then QuickBooks connects read-only. About three minutes end to end, and nothing in your books changes.

Your data, before you hand it over

It cannot touch your books

The diagnostic connection cannot post, edit or delete anything in QuickBooks. You grant it in your own QuickBooks account, and you can revoke it there any time, without asking anyone.

Encrypted and fenced

Connection tokens are encrypted at rest, and every row of your data is fenced to your company at the database layer. The isolation is retested automatically on every change Luca ships.

Seen by your accountant, nobody else

Your books are read to do your books. Nothing is sold, shared with third parties, or used to train models. Leave, and the QuickBooks file was yours all along.

The full list, in plain terms

Read by Adriel himself, reply within a day

Or just tell me what is going on.

Not ready to connect QuickBooks? Write a sentence about your books. I read every note myself and reply within a day. No connection, no card, no call.

Behind on the reconciliations, books that never match the bank, a cleanup you keep putting off. Whatever it is, say it plainly and I will tell you where you stand.

Goes straight to Adriel. No QuickBooks, no card, no call. One person reads it and replies.

Questions

Luca is an accountant and fractional CFO practice. Tax filing and audits stay with your CPA, who gets clean, closed books to file from instead of a year-end cleanup.

Talk to the accountant who will run your books.

Twenty minutes with Adriel. He looks at where you are and tells you what he would do. No commitment, no card.
