The everyday paperwork, done.

Everything below is in the free app, working today.

Invoicing

Send an invoice in a minute.

Create your invoice in Komplet and send it to your client, in the same app where your costs and bank statements already are.

  • Included in the free app
  • Your client, the lines and the VAT
  • Sent to your client from Komplet
  • Next to the rest of your month
  • Send to KSeF
An invoice made in Komplet, ready to send to a client.
Inbox

Drop it in. Komplet reads it.

Drag an invoice onto the Komplet icon in the menu bar, into the window, or open it with ⌘O. Komplet reads the seller, NIP, invoice number, date, amount and currency, from the PDF itself or from a scan or a photo, in Polish and English.

  • Scans and photos are read on your Mac, never uploaded
  • The same file twice? Komplet notices
  • After the first invoice, it knows the supplier
  • You check the fields; you never retype them
Komplet’s inbox: an invoice with the seller, NIP, number, date and amount read from it, ready to file.
Filing

Filed in the right month, under a name you can read.

Komplet writes each document into your own folder tree, one folder per month, named by date, seller and number. Already have years of invoices in folders? Point Komplet at them and it reads what is there.

  • Your folders: on your Mac, in iCloud Drive or in Google Drive
  • Keeps the month folders you already have
  • Every month on one page: documents, payments and statements together
  • Remove Komplet and every file stays exactly where it is
A month in Komplet: every payment next to the document that explains it, with a preview of the invoice.
Bank statements

Every payment finds its document.

Add the month’s bank statement as a PDF. Komplet reads every line and pairs each payment with the invoice that explains it, by invoice number, amount, NIP and seller, even a euro invoice you paid by card in złoty. Whatever is still missing a document shows in amber.

  • PDF statements from any bank, in Polish or English
  • The statement’s own totals are checked, line by line
  • Link by hand when you know better; Komplet never overrules you
  • Bank fees and tax transfers need no document
Komplet’s payments list: cost documents and tax payments across months, paid ones in green.
Taxes and ZUS

Your tax and ZUS payments, read from the statement.

Komplet recognises transfers to your tax micro-account and to ZUS, groups them by tax and period, and shows what you paid, when, and what comes next. Deadlines already skip weekends and Polish public holidays.

  • Paid periods, open periods and year totals in one place
  • A late payment is flagged only when a statement proves it
  • Interest kept apart from the tax itself
  • Your own deadlines on Home, with the days left

For your accountant

One click, and the month is ready for your accountant.

“Export” builds a folder and a ZIP: every document under a readable name, the month’s statements, and a summary as PDF and as a spreadsheet. Send it by Mail, or share a link from iCloud Drive.

  • Every document named by date, seller and number
  • A Statements folder with the month’s bank statements
  • Summary.pdf to read, Summary.csv that opens in Excel
  • Remembers where you keep your packages

Letters

A letter from the tax office, in plain words.

Drop in a letter from the tax office, ZUS, customs, a court or the town hall. Komplet reads it and tells you what they ask, by when, and what happens if you do nothing, in English, Polish or Ukrainian. It drafts a formal reply in Polish and a message for your accountant, then checks every claim against the law.

  • The deadline counted from the day you received it, weekends and holidays skipped
  • The legal grounds explained, with sources: official ones first
  • Asks before it looks at your records, and shows which ones
  • The steps go to your to-dos, with the letter attached

Ask Komplet

  • Every record shared is listed under the answer
  • Turn sharing off and nothing about your records is sent
  • In English, Polish or Ukrainian
  • Never makes up a figure it has not looked up

  • Findings you can explain in one click, or hide
  • Search every document, letter, invoice and bank line

Questions

What people ask before they start.

Something else? Write to us.

Is Komplet accounting software?
No. Komplet does not book entries or calculate tax. It gets your documents in order: read, named, filed by month and checked against your bank statement, so that you, your accountant or your accounting service can do the accounting without chasing paper.
Is it really free?
Yes. Managing your paperwork is free: statements, documents, matching, what is missing, the monthly overview and the export for your accountant. You pay only for more: Connect (39 zł a month) to connect to KSeF and your accounting platform, with Komplet AI included for Ask Komplet, letters explained and Insights. It is free until 31 December 2026 for everyone who starts now. See pricing.
What does Komplet AI send, and to whom?
Only what you allow, to Google’s Gemini, through Google’s Firebase. A letter is sent when you ask for it to be explained; before Komplet shares any of your records, it shows which ones and waits for your yes. Every answer lists what was shared. Everything else, your documents, statements and folders, stays on your Mac. Privacy.
Does it work on Windows, the web or my phone?
No. Komplet is a Mac app. There is no Windows, Linux or web version.
Where are my documents kept?
In your own folders, where you choose: on your Mac, in iCloud Drive or in Google Drive. Komplet keeps an index of what is in them, never the only copy.
Which banks’ statements can it read?
PDF statements from any bank, in Polish or English. You add statements as files; Komplet never logs in to your bank.
I already have an accountant. Why would I need this?
Because your accountant does the accounting, not the collecting. Komplet gets you from a bank statement to a complete month: every payment with its document, the missing ones flagged, and one package to send. If you do your own books, it keeps the documents in order for you the same way.
I don’t speak Polish. Will this help?
Yes. Komplet works in English and reads Polish invoices for you. Our guides explain JDG, ZUS, VAT, KSeF and the rest in plain English.
