AI bookkeeping for self-employed in Luxembourg

Send invoices, snap receipts,and the tax forms build themselves.

Made for the self-employed in Luxembourg. Invoicing and receipt scanning are free, forever. Pay only for the tax forms: your TVA return and Forms 152 and 110, ready to file.

No card needed. The free plan stays free.

  • Free

    Send invoices

    Pick the client, pick the product, send the invoice from your phone. Lisa books it and carries the figures into your tax returns.

  • Free

    Scan purchases

    Snap a receipt or supplier invoice, or email the PDF to your Lisa address. She reads the lines, supplier and VAT, and books it.

Lisa AI

Ask in your own words. She reads your books before she answers.

Lisa is not a search box over a help page. She reads your invoices, your payments and your ledger, and she knows the Luxembourg rules that apply to them. So “who still hasn't paid me” gets names and amounts, not an article.

Ask what you would ask an accountant: whether something is deductible, how much VAT you owe this quarter, how this quarter compares to the last one, what happens if you cross the franchise threshold.

  • Answers computed from your own records, not from averages.
  • Current Luxembourg rules, plus our own reference base for the cases the law leaves open.
  • Every answer links to the documents and entries it came from.

Lisa is AI and can make mistakes. No substitute for tax advice.

Purchases

Photograph the receipt. That's the data entry done.

Snap it with your phone, drop in a PDF, or forward the invoice to your own Lisa email address. She reads the supplier, the date, the amounts, the VAT rate and the category, and creates the purchase record for you to confirm.

No typing amounts into a spreadsheet on Sunday evening.

  • Photo, PDF, or email forwarding — whichever is in front of you.
  • Supplier, dates, totals and VAT read from the document itself.
  • Duplicates caught, so the same invoice never lands twice.
  • You confirm; nothing is booked behind your back.

Send an invoice. The bookkeeping happens behind it.

Build invoices from your catalog of services and products, in your own currency and VAT treatment. Every invoice you send writes itself into the books — so the sales side of your TVA return and your profit and loss are already correct when you get there.

  • A reusable catalog, so a recurring service is two clicks.
  • The right VAT treatment per line, including reverse charge VAT for clients outside Luxembourg.
  • Payments recorded against invoices, so you can see what is still open.
  • Sales feed the reports and the tax forms automatically.

Taxes and reporting

The forms, prepared. The deadlines, watched.

Lisa keeps a calendar of your Luxembourg obligations and builds your VAT return and tax forms from the records already in the app — and you can follow any figure on them back to the invoice or receipt it came from.

  • Quarterly and annual TVA returns, franchise or normal regime.
  • Form 152 and Form 110 for your self-employed activity.
  • Profit and loss, balance sheet, operating expenses, depreciable assets.
  • A calendar of the Luxembourg obligations that apply to you.

You review and submit. On the Care plan a registered accountant keeps your books, signs them and submits for you where that is possible.

What people ask us before they sign up

“It's AI. What if it gets it wrong and I'm the one who pays?”

You never have to take it on trust. Every number in every report opens: click a line and see the entries behind it, and the receipt or invoice behind those. Nothing is booked until you confirm it. And if you would rather an accountant reviewed and signed it, that is the Care plan.

“I don't know the Luxembourg rules, and I don't know what I'm missing.”

Lisa does. Franchise or normal TVA regime, reverse charge, deductibility limits, the filing calendar — she applies the current Luxembourg rules and tells you what is due and when.

“I can't justify a fiduciary at my size.”

BravoLisa starts free, and €14.99 a month if you want Lisa preparing your forms — less than accounting services in Luxembourg cost — and it answers in seconds. Your figures are there whenever you want to look, not once a year in a PDF. See how Care works.

A registered accountant keeps your books and answers for them.


  • Everything in Smart
  • A registered accountant keeps your books and signs your declarations
  • We sign every form. We submit it for you when possible.

A registered accountant keeps your books and prepares, signs and files Forms 152 and 110. Form 100 — your household income tax return — is included when it is a straightforward one. The Care page says what that covers and how it starts.

What we promise

01

Your data is yours.

Export everything, whenever you want. Stop paying and you drop to Free — your records stay, nothing is locked away, nothing is held hostage.

02

No black boxes.

Every figure in every report opens down to the entries and the source document that produced it. If Lisa cannot show you where a number came from, she should not be showing you the number.

03

A human answers.

Write to us and a person replies within one working day. Not a bot, not a ticket number.

Everything else

Do you file my declarations for me?

On Free and Smart, no — Lisa prepares the forms and you review and submit them. On Care, a registered accountant keeps your books, signs your declarations and submits them for you where that is possible, and Form 100 — your household income tax return — is included when it is a straightforward one.

What happens to my documents? Does the AI learn from them?

Your documents are yours and are not used to train models. The details are in our AI Use Notice and Privacy Policy. Read the notice.

I already have a fiduciary. Is this useful?

Yes. Your books stay in order all year and your fiduciary receives clean records instead of a folder in January. Many people keep both.

What do I need to get started?

A few questions about your activity — what you do, your business permit, your trade register and VAT registration, your address. Then you can photograph your first receipt. You do not need to enter your history first. How to apply for a business permit, in our knowledge base.

What if I stop paying?

You drop to the Free plan. Your records stay and you can export everything at any time.

Franchise or normal VAT regime?

Both are supported — the franchise regime, Luxembourg's VAT exemption for small turnover, and the normal regime. Lisa applies the one that matches your registration, including the annual declaration under the franchise regime.

What if my client is in another EU country?

For most services to a business client with a valid EU VAT number, you charge no Luxembourg VAT: Lisa marks the invoice reverse charge, and your client accounts for the VAT at home. The sale goes into your VAT return and your recapitulative statement. For most services to a private client, Luxembourg VAT applies — unless you are on the franchise regime. Goods and certain services follow different rules.

Is BravoLisa only for Luxembourg?

Yes. The rules, the forms and the deadlines are Luxembourg-specific, and that is the point.

What about my bank?

Bank features are in development and not available yet.

Is BravoLisa an accountant?

No. BravoLisa is bookkeeping software with an AI assistant. On the Care plan, a registered Luxembourg accountant keeps your books and signs your declarations.

The self-employed deserve a bravo.

You took the risk, you do the work, you carry the admin nobody sees. Let Lisa carry the admin part.

Free plan, no card, five minutes to your first receipt. The call, if you book one, is in English.

You answer a few questions about your activity, and you are in. No card, no import, no setup call. Photograph your first receipt and see what Lisa does with it.
