Compliant invoices (VeriFactu) free forever, your 303 and 130 forms computed from your invoices, and a copilot that answers from your real data: what you billed, the VAT you paid, who still owes you. No mandatory accountant, no lock-in, no sales calls.
Been invoicing for years? Upload your history (PDFs, photos or a ZIP with everything mixed): the AI classifies it, you set the next number of your series and your accountant joins as a guest.

What it does
Accounting that works while you look away
VeriFactu built in
Every invoice with a chained hash and QR, as Royal Decree 1007/2023 requires.
Nothing to do until your date: Billy already stores your invoices in the legal format today.
Automatic bookkeeping
Forward the client email or the supplier invoice: Billy drafts the invoice or classifies the expense, VAT verified.
The AI reads; the code recomputes amounts and VAT and rejects what does not add up.
A copilot that knows your numbers
An accounting expert with access to your data: ask who owes you, how much VAT you paid or how an expense is deducted.
It only reads and creates drafts: nothing is approved or sent without you.
Taxes computed, ready for the tax agency
Forms 303, 130, 111, 115 and 349 come out of your invoices, with the file in the official format and warnings when something is off.
Billy prepares the file; you or your accountant file it, seeing the same screen.
A look inside
Everything Billy does for you, screen by screen
Pick a feature and watch it work. These are real captures of a demo account: what you see is what you will see as soon as your first invoices come in.
Your whole business on one screen
Income, expenses and profit for the period, what is still to collect, review or reconcile, and the quick actions to sort it out. Open Billy and you know where you stand, without digging.
- Period finances compared with the previous one
- Pending actions: collections, documents to review, movements to reconcile
- Monthly invoicing, best clients and biggest suppliers of the year
A legal invoice in 30 seconds
Describe it in your own words and the AI drafts it with the client, the lines and the VAT. You review and approve: numbering and the VeriFactu record are automatic. Quotes follow the same path and turn into an invoice with one click.
- AI drafts: you describe, Billy proposes, you approve
- Automatic numbering and VeriFactu record on approval
- Quotes that turn into an invoice in one click; PDF and email in each client's language
Expenses come in by themselves
Every company gets its own Billy address. Forward your suppliers' invoices, or give them the address directly: the AI reads them, checks that the figures add up and leaves them in the Inbox ready to accept. You can also upload PDFs, photos or a ZIP with everything mixed.
- Your own email address for receiving invoices
- AI reading and arithmetic check before anything is accepted
- The PDF and the extracted data side by side, reviewed in seconds
The bank reconciles itself
Upload the statement in any format (CSV, Excel, PDF…) and every movement finds its invoice: client payments, supplier receipts, contributions and payroll. Whatever does not match stays in a short queue for you to review.
- Without handing your bank credentials to anyone: upload the statement (CSV, Excel, PDF) and that's it
- Every movement linked to its invoice, with a confidence level
- Self-employed contributions, payroll and internal transfers detected
The quarter, computed before you ask
Billy prepares the 303, 130/131, 111, 115, 349 and the annual summaries (390, 347, 180, 190) from your real invoices, explains every box and reviews with AI what might be wrong. Ask what you don't understand and request changes: you decide, it recalculates. Corporate income tax (200/202) is not prepared by Billy. No extra cost: switch it on with one click in Settings → Taxes.

Ask your business anything
"How much have I invoiced this client?" "What have I paid in rent so far?" "Who owes me money?" The copilot queries your real data and answers instantly, from any screen. It only creates drafts: approving and sending is always up to you.
- Answers with your real figures, not estimates
- Available on every screen and in your language
- Drafts only: it never approves, numbers or sends
Know where the money goes
Tags classify income and expenses by concept (#web-design, #rent, #saas…) and the AI tags for you. With that, Billy shows you where income comes from, where expenses go and which clients concentrate your invoicing.
- Automatic AI tagging, fixable with one click
- Income and expenses by tag, with their evolution over time
- Client and supplier ranking, average ticket and days to collect
Clients and suppliers, without typing records
Import your contacts from any file (Excel, CSV, PDF, a plain TXT…) and the AI structures them. From a name or a tax ID, Billy looks up the rest in public registries and completes the record. Duplicates are detected and merged.
- Import from any file format
- AI enrichment from a name or a tax ID
- Duplicate detection and merging
All captures come from a demo account with fictional data. No card needed to start.
Who it is for
Built for genuinely small businesses
Freelancers
Invoices with the right VAT and IRPF withholding, budgets that become invoices in one click, and every expense organized without data entry.
Studios and agencies
Per-project budgets, recurring billing to clients in their language (Spanish, Catalan or English) and a dashboard of what is collected and pending.
Small limited companies with a team
Up to five people on the same account (Max plan), payroll recorded for the 111 and 190, supplier invoices processed on their own from the inbox, and your accountant as a read-only guest.
Your documents train no one
Billy is hosted in the European Union and reads your invoices with AI models we run ourselves, on our own European servers: your data never travels to third parties, it is processed only for what you ask, and by contract it is never used to train any model.
Your data, yours alone
It is yours, not ours. Download everything whenever you want (invoices, contacts, statements and tax forms, as PDF, CSV/Excel and ZIP) and take it wherever you decide, with no lock-in or fine print. Every company lives isolated from the others, every action is kept in an audit log and your documents are stored encrypted with AES-256 on the server.
Frequently asked
Everything you want to know before you start
Can I try it without a credit card?
Yes. The Free plan works forever without a card. During launch, Pro and Max are activated with an invitation code (ask for one at hola@askbilly.net); card payment is coming soon.
Does it really comply with VeriFactu?
Yes. Every approved invoice is chained by SHA-256 hash to the previous one, with QR and a tamper-proof registry (only appended, never deleted), exactly as Royal Decree 1007/2023 requires. When the obligation kicks in, your invoices will already be in the correct format from day one.
Does Billy send my records to the AEAT?
Not yet. Today Billy works in the no-submission mode: it generates the record of every invoice with a chained hash and QR and keeps it tamper-proof, which is what Royal Decree 1007/2023 asks for while the obligation is not in force. Voluntary submission to the AEAT (VERI*FACTU) is in development to arrive before 1 January 2027. Nothing will be sent without you seeing it.
Does Billy file my taxes for me?
It computes the 303, 130/131, 111, 115, 349 and the annual summaries (390, 347, 180, 190) from your invoices, reviews them with AI and generates the file in the AEAT format. Filing is done by you or your accountant by importing that file into the Sede Electrónica: nothing is sent without you seeing it. Corporate income tax (200/202) is not prepared. No extra cost: switch it on with one click in Settings → Taxes.
What if the AI misreads an invoice?
The AI interprets, but code verifies: it recomputes bases, VAT and totals and rejects any reading that does not add up instead of saving it. Whatever passes arrives as a draft, with the original document beside it, and nothing is approved, booked or sent without your confirmation.
Does it connect to my bank?
No direct connection yet: you upload the statement your bank gives you (CSV, Excel or PDF) and Billy matches each movement to your invoices and expenses, marks what is collected and paid and leaves you only what it does not recognise to review. One statement a month is usually enough.
My accountant handles my books. How do they fit in Billy?
Pro and up include a free read-only seat for your accountant: they download full quarters (PDFs + summaries) without asking you for anything. It is an extra seat on top of yours, at no cost. Billy is built for the freelancer or small business doing the invoicing, not for firms managing a client roster.
I come from Holded, Quipu or a spreadsheet. How do I switch?
Upload the invoices from previous years (PDFs, photos or a ZIP with everything mixed): the AI reads them and classifies them as issued or received. Every old invoice goes through the AI scan; if you are going to upload several years at once, write to hola@askbilly.net and we will make sure the migration does not eat your monthly quota. Import contacts from any file. In Settings you set the next number of each series so your numbering continues without gaps. On the Max plan we help you with the migration.
Is the data mine? Does the AI train on it?
It is yours. Every company lives isolated from the rest, documents are stored encrypted (AES-256) on servers in the European Union and the AI that reads them runs on our own infrastructure, with a contractual guarantee that they are never used to train any model. You can export everything (PDF, CSV/Excel and ZIP) at any time and take it wherever you want.
Is it for freelancers or for companies?
Both. A freelancer has form 303 and 130 (or 131 under modules); a company has 303, 111, 115, 349 and the annual summaries. Billy adapts the calendar and the forms to your regime and warns you of every deadline. Only corporate income tax (200/202) is out of scope.
Which languages is it available in?
Spanish, Catalan and English, switchable any time. Invoices, quotes and emails go out in each client’s language, not yours; only the legal VeriFactu legend is always in Spanish, as the AEAT requires.
Can I cancel anytime?
Yes, one click from Settings. No lock-in, no penalty, and before you leave you download all your invoices and statements (PDF, CSV/Excel and ZIP) from Downloads.
Start today. Invoice tomorrow.
Creating your company takes a minute. The first invoice, five.
