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.
- 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.
- 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.
- 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.
- 04
Input VAT lost in an audit
VAT charged by a supplier that is not registered, or at the wrong rate, cannot be deducted. It often comes to light years later, in a VAT audit.

We check by Swiss rules
Each invoice is read and checked: sums, the VAT rate for its date, the supplier’s entry in the federal UID register, the IBAN and duplicates.
- 03
Report and Excel
You see which invoices need a second look before you pay, and download everything as an Excel file.
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 invoices you uploaded earlier
- Net plus VAT equals the total
- Swiss VAT rates valid on the invoice date
- 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

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; the answer appears in the report as soon as it comes. 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. 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?
