What's new in Zettl

• New

  The Start and Firma plans now apply as priced: the number of companies, Fio accounts, users and AI-read documents a month.

• Improved

  The AI reads documents up to 10 MB and 20 pages. The app refuses a larger file before uploading it, so you can split it.

• New

  A new Contact page with a form and an overview of where to write about what.

• New

  A What's new page with the version history.

• New

  Zettl has moved: the website is at zettl.cz and the app at app.zettl.cz. Old zettlapp.com addresses forward you there.

• Improved

  Free access now follows its owner: a company you create or take over gets the same free plan, for up to 3 companies.

Subscriptions, a new website, a new Budget and Analytics, and a long list of fixes.

• New

  Subscriptions: the Start plan at 150 CZK a month and Firma at 350 CZK a month, paid by card and managed in Settings → Subscription.

• New

  New companies get the first 14 days free, no card required.

• New

  Existing customers get the Firma plan free of charge.

• New

  A new Budget: every recurring payment is checked against your Fio statement, and recurring payments the budget doesn't track yet are suggested.

• Improved

  Analytics is now an owner's report: comparison with last year, cash flow, who pays, unpaid receivables, document coverage and output VAT.

• Improved

  A new zettlapp.com shows how matching payments with documents works, and lists the prices.

• Improved

  Public pages arrive as ready-made HTML, so they show right away, even without JavaScript.

• Improved

  New terms of service (version 2.0), privacy policy and data processing agreement; for existing customers the new terms apply from 15 November 2026.

• Security

  Deleting your account now also deletes your uploaded documents and logos.

• Improved

  Zettl is in Czech and English; links to the German version lead to English.

• Fixed

  Views no longer leave out data for companies with more than 1,000 records.

• Fixed

  Unmatching removes only the chosen document, and the transaction no longer shows as matched afterwards.

• Fixed

  Matching by variable symbol no longer links the wrong invoice.

• Fixed

  An uploaded GPC statement no longer duplicates payments Zettl already fetched from Fio's API.

• Improved

  Search also covers the counterparty and variable symbol, and PayPal and SumUp payments show the right payee.

• Fixed

  Uploading documents by drag and drop, and from the document picker while matching, works again.

• Fixed

  A tab left open during a Zettl update reloads once instead of showing an error.

• Improved

  When you're signed out, app pages send you to sign in and then back where you were.

• Improved

  A new look across the app: a new sidebar with a company switcher, a new dashboard with month tiles, and pages that were partly in English are translated.

• Fixed

  Enter in the company ID field no longer submits the client form, personal Analytics no longer counts income as spending, and budget amounts use Czech formatting.

• New

  Connect Zettl to an AI assistant such as Claude: sign in with your Zettl account and the assistant can see your invoices, documents and payments.

• Security

  Sign-in and password reset are protected against bots with a CAPTCHA.

• Fixed

  Uploading a file with the same name no longer overwrites an older document.

• Fixed

  When a payment is matched to several documents, the second one shows its transaction too.

• New

  Import bank statements in GPC/ABO format: several files at once, with a preview of each statement and a balance check.

• Improved

  Matching works across the whole company, whoever uploaded the documents and payments, and pairs exact amounts right away.

• Fixed

  Rejecting a suggested match is now saved, and ISDOC import keeps the VAT.

• Fixed

  A statement another company has already imported now imports correctly instead of reporting only duplicates.
