For US businesses on QuickBooks Online
One accountant runs your books. You see everything, any hour.
Your month closes by the 5th, and your portal never closes: live reports, a weekly cash pulse, answers in writing.
Luca is the practice. Adriel is your accountant. The AI is his checklist, automated.
Connect QuickBooks read-only. No card, no call. You get a written review of your books within 48 hours. From $1,200/mo flat.

Answered that same Sunday night, from the books.
The question takes one line. The answer does not wait for Monday.
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.

The difference
You get asked about the $1,842, not the $45.

Last month at the demo company below: everything else was categorized from history without asking, and what is left comes ranked by the money it moves.
You answer in one line, in your own words, and it posts to QuickBooks with the account, class and memo already written.
The AI drafts. Adriel reviews and posts it himself, so nothing reaches QuickBooks without a person checking it first.
And every question and answer stays written down in your portal, searchable years later.

Post to QuickBooks
Run by Adriel Kornschuh.
Accountant and fractional CFO. The accountant behind Luca.
Based in Buenos Aires, working US Eastern hours.
One senior accountant on your file, not a junior rotating through it.
A lot of software is arriving at accounting from the outside right now. This is the other direction: an accountant with a business administration degree who did this work from the inside, and got good at software. 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. Working from Buenos Aires instead of a US city is why one accountant covers bookkeeping and CFO work at this price, not two separate invoices.
- 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.
- 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.
- 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.
Connect on LinkedInA first group of ten this year
Luca is new, and that is the reason to come in now.
No wall of logos, no testimonials, because there is nothing to show yet and a fabricated one would be worth less than saying so. What being early buys you:
One accountant owning the work. The same accountant closes the month, writes the commentary and answers in the thread.
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.
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.
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.
If you say yes
Your first 30 days, written down before you start.
Nobody should hand over their books on a promise. This is the schedule you can hold me to, and the last line is the one that matters most.
- Day 1You connect QuickBooks read-only, in your own account, in about three minutes. Nothing in your file changes, and you can revoke it from there any time.
- Days 1 to 3The diagnostic comes back in writing: your books graded 0 to 100, and the fix list in the order that actually matters. It is yours to keep either way.
- Week 1Your portal opens with your own numbers in it, and the first weekly cash forecast lands. You stop asking where things stand and start looking.
- Weeks 2 to 3Questions arrive ranked by the money they move. You answer in one line, in your own words, and the categorization posts itself to QuickBooks.
- By the 5thThe first month closes and the written report arrives: what changed, what it means, and what to watch. Your old bookkeeper can still be working in parallel the whole time.
- If a date slipsYou 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.
This is the product. Drive it.
Luca does the books; this portal is where you watch them happen. Open every section, ask questions, break nothing.
Two questions are waiting on you, the oldest since Friday. The September close pauses at these.
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 thingOpen 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.
Four steps, then Luca runs your books.
Plug and play on the QuickBooks you already have. Nothing to install, nothing to migrate.

Priced in public
One flat fee. Three sizes. All of it on this page.
Ask most firms what they cost and you get a discovery call. Here the whole list is public, because the service works the same way: you see the price before you commit, the way you will see your own numbers after.

No contract, no notice period, leave any month. Your QuickBooks stays yours the whole time. Every size assumes up to about 500 bank and card transactions a month; 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 $1,500 to $2,500; the ten founding companies pay half of that. Payroll runs, tax filing and audits stay with your CPA at every size. Already decided? Start the free diagnostic: as soon as your QuickBooks connects, you can sign at the listed price on the spot, no waiting on anyone.
The whole month, or a piece of it
Everyone prices a piece of the month. Luca prices all of it.
every one of them is your evening
you review and approve every week, and you still hire an accountant
statements arrive, but nobody reads the numbers
the rest is billed hourly, and answers take days
all six, one flat invoice, no hours to approve
- 1Transactions categorized
- 2Month closed on a documented checklist
- 3A written report that explains the month
- 4A weekly cash forecast
- 5A live portal, open any hour
- 6Questions answered by someone who knows your books
Every row is the same month of work. Filled blocks are jobs the price covers; striped blocks are the ones left to you. The six are included at every Luca size, receivables and payables start on Core as the plans say, and each competitor cell comes from the comparison table, last reread against their own sites in August 2026. Where that table is ambiguous, the credit goes to them.
Where Luca is the wrong fit
- Under $1M a year or pre-revenue. The price does not earn its keep yet; the free diagnostic still works and is still free.
- Not on QuickBooks Online. The whole service runs inside your QBO file, so there is no version of this without it.
- Looking for tax filing only. Filing stays with your CPA; Luca closes the books your CPA files from.
- Wanting a bookkeeper at the next desk. Everything here happens in writing, in the portal, on US Eastern hours.
Weighing it against doing it yourself or buying software? The honest comparison
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.
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.
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.
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.
