AI financial advisor — the financial brain of your business

Ordinary invoicing tools only record. ID Faktura has a built-in AI analyst that knows your numbers and tells you where you are losing money — and where you can make it.

Company data analysis on demand

Who owes you and whom to chase first. Which products you are selling at a loss. How much cash is frozen in unpaid invoices and stock. One question — a concrete answer with numbers.

It watches before you ask

Along with the answer, the advisor flags what matters: growing overdue balances, falling margins, the approaching VAT exemption threshold (art. 113). Like a good accountant — only available 24/7.

It understands Polish — spoken too

“Invoice for Nowak, window fitting, 2 units at 1,200 zł net, due in 14 days” — say it or type it and the assistant prepares a filled-in draft. You just check it and click “Issue”.

Numbers from the system, not from imagination

A hard rule: the AI interprets — the system calculates. Every figure in an answer comes from your own reports, not from the model’s “knowledge”. The AI never issues or sends anything on its own — the decision is always yours.

AI financial advisoron your company’s data
Who owes me money and whom should I chase first?
Your customers owe you a total of48,320 zł, of which 31,200 zł is more than 60 days overdue. Most urgent:Nowak Sp. z o.o. — 18,400 zł, 74 days overdue(recovery drops sharply after 90 days). I suggest a payment demand — I can prepare it in one click.
And which products have the worst margin?
You are selling three productsbelow purchase cost— the biggest loss is on “3D hinges” (−8.4%). Also note: you have already used82% of your VAT exemption threshold— at the current pace you will cross it in November.
Example conversation. The AI advisor is available in the Standard plan and above.

FAQ

Frequently asked questions

Yes. We generate invoices in the FA(3) schema compliant with the current KSeF 2.0 specification. You upload a certificate (online or offline) generated in the KSeF Taxpayer app and send invoices straight from our system.

Yes — every plan has a 30-day free trial with full features and no card required. After the trial you pick a plan; if you do not, the account switches to read-only and all your data stays available to view and export.

Yes, at any time. An upgrade (e.g. Start to Standard) takes effect immediately. A downgrade or cancellation applies from the next billing period — you keep full access until the paid period ends.

The account switches to read-only: nothing disappears, you can browse and export all your data, but issuing new documents requires choosing a plan. Every plan has unlimited invoices.

Your data sits on servers in Poland (Olsztyn). KSeF certificates are encrypted with AES-256-GCM and passwords are stored only as bcrypt hashes — nobody, including us, can read them from the database. Daily backups with restore testing. GDPR compliant, with a data processing agreement (DPA) available to download.

Yes — at any time you can export all invoices (PDF + XML) and contractors (CSV/Excel). Also after cancelling your subscription.

No. You can issue invoices in the app right away. A certificate is only needed to send invoices electronically to KSeF (mandatory: large companies from 1 Feb 2026, others from 1 Apr 2026, micro businesses from 1 Jan 2027). You generate it free of charge in the Ministry of Finance Taxpayer app.

After choosing a plan you are redirected to the secure Paynow (mBank) gateway. We accept payment cards, BLIK and bank transfers. A VAT invoice is generated automatically.

It is an AI assistant built into the program that knows your company’s data. You ask in Polish — typing or speaking — and it answers with specifics: who is overdue and whom to chase first, which products have the lowest margin, how much room is left under the VAT exemption threshold, how sales compare month over month. It can also draft an invoice from a command — you always approve the document yourself. Available in the Standard plan and above.

The AI advisor answers solely from your own account data — every figure comes from the system’s reports, not from the model’s “knowledge”, and the AI cannot see other companies’ data. Queries are processed by a commercial enterprise-grade language model; your data is not used to train public models. The AI never issues or sends anything on its own — a human always approves.

Switching software

Switch without retyping

You do not start from an empty system. We move what you already have — and from the next day you keep invoicing, with the same catalogue and the same stock levels.

Your document history stays

Invoices, receipts and corrections from your old program land in the ID Faktura archive — numbering included, so continuity is preserved and everything is in one place during an audit.

Stock levels and catalogues

Products with prices, EAN codes and stock levels; contractors with tax IDs and addresses. No stocktaking “just to switch” and no retyping of your customer base.

Subiekt nexo — automatically

You get a small program that reads the Subiekt databaseread-only(it changes nothing there) and moves the data into ID Faktura. Proven on over 20,000 documents.

A different program? We will write the import for you

You can load products and contractors yourself from a CSV file (templates are in the app), and we pull purchase invoices straight from KSeF. If your system exports in a different format, we will build the import to order. Tell us what you are moving from.
