Fictional companies and invoices, for illustration only.

Klyrenta does not pay, book or decide anything. It checks every invoice by the same rules and shows you what it found.

The problem

Where money gets lost on supplier invoices.

Each of these happens in small businesses, usually because nobody has time to check every invoice twice.

  1. 01

    Copying by hand

    Amounts, IBANs and references are typed into e-banking and bookkeeping one by one. It takes time, and one wrong digit is easy to miss.

  2. 02

    Paying twice

    The same invoice arrives by post and by email, or again as a reminder. Without a check it gets paid twice, and the money is hard to get back.

  3. 03

    Fake bank details

    A forged invoice or an email with “our new bank details” looks like it comes from a real supplier. Once paid, the money is usually gone.

  4. 04

    Input VAT lost in an audit

    VAT from a supplier that is not registered is not deductible, and a wrong rate can cost the deduction in a VAT audit, often years later. Klyrenta checks both and points them out before you file.

  2. 02

  3. 03

    Report and Excel

    You see which invoices need a second look before you pay, and download everything as an Excel file.

How each check works
What we check

Every invoice, the same checks.

Each check is a fixed rule, not a guess. The report says which rule flagged an invoice and why.

  • Duplicates, also against the last 2’000 invoices in your account
  • Net plus VAT equals the total
  • Valid Swiss VAT rates; what counts is when the service was supplied
  • VAT amount matches the rate
  • Supplier registered for VAT in the federal UID register
  • IBAN check digit, and bank details that changed since an earlier invoice
  • UID format and check digit
  • Missing invoice number, date or supplier
  • Due date before the invoice date
Your documents

What happens to your invoices.

Invoices contain business data. This is how we handle them.

  • Hosted in Switzerland

    Your account, documents and results are stored on servers in Switzerland, operated by Infomaniak Network SA.

  • Not used for training

    To read a document we send it to Anthropic’s API. Under Anthropic’s commercial terms, this content may not be used to train its models.

  • Deleted after 90 days

    Uploaded files are deleted 90 days after processing. The results stay in your account until you delete the account yourself (or ask us to), or until it has gone unused for 24 months (we tell you 30 days before).

  • No tracking cookies

    No advertising and no tracking scripts. Visits are counted on our server, without cookies.

Common questions

Does Klyrenta pay or book my invoices?

No. Klyrenta only checks. You decide what to pay and pay it as before, from your own e-banking. Bookings stay in your accounting software; the Excel file makes them easier.

What if the UID register cannot be reached?

The report says “UID register not reachable” for that invoice, and the site asks the register again by itself during the following 7 days; the answer appears in the report as soon as it comes. If none comes, the report says so, and you can check the number yourself on uid.admin.ch. An invoice is never marked as wrong just because the register did not answer.

Is the VAT pre-check tax advice?

No. It applies fixed rules to your invoices and shows what to look at. It does not replace your fiduciary or your own responsibility for the VAT return.

Which files can I upload?

PDF, photos (JPG, PNG or WebP), XLSX and CSV, up to 50 files at once. Every PDF page counts as one invoice. A spreadsheet that lists several invoices is checked row by row, and each row counts as one invoice. Clear photos give the best results, and the report always shows what was read.

Do I need a subscription?

No. The invoice check starts with 10 free invoices, and a pack of 100 is a one-off payment. Monthly plans are there for larger volumes and can be cancelled any month.

How can I reach you?

Through the contact form. You can also leave a question or a suggestion with the link at the top of every page.
