How many separate programs
does your financial life really need?
Bookkeeping, tax, POS, payroll for the business — household budget, contracts, retirement planning for personal life: usually ten programs that don't talk to each other, split across two separate worlds. PilotOS combines both in one system that runs entirely on your own hardware.
Your numbers stay with you — even if PilotOS ceased to exist tomorrow.

Most finance apps don't actually belong to you.
You rent access to your own numbers — and the day you cancel, it's gone. PilotOS flips that around: the software runs on your hardware, your data stays local, and everything keeps working even if we disappeared tomorrow.
Your data, your machine
Accounting, receipts, journal — everything stays encrypted on your own hardware. No provider can read along, lock you out, or discontinue the product and take your data with it.
No subscription lock-in
The free tier stays free permanently. And with a lifetime license, the software is truly yours — no monthly rent just to access your own numbers.
Audit-ready from day one
Signed receipt chain, gapless journals, GoBD export for tax audits. A crash never costs you a booking — every change is secured and traceable.
No field without an explanation
Every input comes with guidance: plain language instead of jargon, an example of a correct entry, and a note on what the value means for tax purposes. No accounting degree required.
One system instead of ten tools
Accounting, tax, invoicing, POS and household budget work together — no export-import chaos between five programs that don't know each other. Enter once, posted everywhere.
Privacy without fine print
What never goes to the cloud can't be lost. Local data storage satisfies GDPR by design — no data-processing agreement with a US provider required.
This philosophy extends beyond software — more on the idea behind it in the (German-language) Wirtschaftliche Heimat initiative. Built by someone who wrote accounting software for around 2,000 businesses back in the 1990s — read the story →
Enter once. Available everywhere. Evaluated automatically.
Every receipt is captured exactly once — and is immediately available everywhere: posted in accounting, factored into VAT and the German EÜR profit statement, visible in liquidity, pricing and reporting. No second typing, no export-import, no figure that reads differently in two places. One entry, one truth.
Capture once
Enter a receipt, invoice or till slip a single time — manually, by scan, or via bank statement import. The system takes care of the rest.
Posted everywhere
The entry automatically flows into accounting, VAT pre-return, the EÜR profit statement, open items and the cash book — personal or business, without a second entry.
Evaluated instantly
Liquidity, tax reserve, P&L and key figures update in real time. You see the consequence of a decision immediately — not just at year-end.
One clean cockpit — for business and life.
Liquidity, tax, POS, household, legal and health — the same clear, local interface everywhere.

From your first invoice to your power of attorney.
PilotOS doesn't stop at bookkeeping. Business and personal life run in the same system — the same numbers, the same independence. That's the actual difference to "just another app".
Everything a company needs
Double-entry bookkeeping (German SKR03/04 chart of accounts), EÜR & VAT, e-invoicing (ZUGFeRD/XRechnung), fiscal-signature POS, payroll & social security, inventory management, fixed assets & depreciation, mileage log, tax returns up to e-balance sheet — plus startup and legal assistants.
And everything that matters privately
Household budget with a budget indicator, contracts & subscription detection, insurance, debt, investments, real estate, pension & retirement planning, estate planning and advance directives — down to health and deadline tracking.
From accounting, tax & POS to household budget, contracts & wealth, all the way to health, retirement & estate planning — all local, on your own computer.
The Butler guides you through every module
In the app and on the website: the PilotOS Butler explains, warns, and jumps straight to the right field with you. One face for every area — from accounting to retirement planning.
Modules across six areas of business and life
One system covers what would otherwise take a dozen separate programs. Click a module with its own page to dive deeper (module pages are currently German-only).
One program instead of five that don't know each other.
No more exporting here, importing there, and numbers that never quite match: accounting, e-invoicing, tax returns, POS and advisory tools — personal and business, all under one roof. You activate what you need and can always add more later.

One decision – every consequence visible.
A big purchase, a new contract, a private withdrawal: in most programs you only find out what it cost at year-end. PilotOS calculates the effect on liquidity, tax burden and reserves immediately — and warns you before a decision gets expensive.
One purchase, one contract, one posting — PilotOS calculates the consequences across every area and warns you before a decision gets expensive.
PilotOS doesn't guess. It reads.
Others guess. PilotOS calculates.
Most finance apps ingest your bank transactions and guess the category — miscategorized entries are the most common user complaint. In a tax audit, a guessing error can quickly turn into a back-payment. PilotOS is built on real double-entry bookkeeping: every figure comes from a posted receipt, not an assumption.
- Built for the self-employed & business owners — exactly where other tools hit their limits.
- Tax, GoBD and real bookkeeping as the foundation, not an add-on.
- No forced open-banking reauthentication, no subscription, no ads.
Ready in 5 minutes – no credit card.
Start with the free tier or have PilotOS demonstrated on your specific case. No cloud account, no payment details, no risk.
Learn bookkeeping risk-free – in training mode.
PilotOS has a real training mode: post, correct, discard, reset — as often as you like. Only when you click "adopt" does it become your real, GoBD-compliant bookkeeping. And the interface guides you from beginner to expert.
Training mode & GoBD – cleanly separated
Training (freely editable and deletable) and live (GoBD-compliant, reversal instead of deletion) are two separate worlds. Only what you deliberately adopt ends up in your real bookkeeping.
From beginner to expert
Guided mode for newcomers, expert mode for speed, Butler help and 3-level field guidance (F1) on every field — plus an academy with over 140 practice cases.
