How it works

What happens to an invoice you upload.

Every document goes through the same steps and the same rules. Here is what we check, how your data is handled and what we do not do.

  1. 01

    Upload

    Upload PDFs, photos (JPG, PNG or WebP), XLSX or CSV in your account, up to 50 files at once; a spreadsheet that lists several invoices becomes one document per row. A fiduciary’s clients use their private link instead.

  2. 02

    Read

    The document is sent to Anthropic’s API, which reads supplier, invoice number, dates, UID, IBAN, amounts and VAT. You see every value that was read.

  3. 03

    Check

    Fixed Swiss rules are applied to what was read: VAT rates by date, the UID register, IBAN and UID check digits, sums and duplicates.

  4. 04

    Report and Excel

    A result for every invoice (OK, warning or error, with the reason) and an Excel file with all the data.

The rules

Each check, explained.

No scores and no black box: every warning names the rule behind it.

VAT rates by date

The rate must be the one in force when the goods or services were supplied. In the first quarter after a change (January to March 2024), an invoice may still correctly show the earlier rates, so both are accepted then. Older invoices are checked against the rates of their time.

01.01.2011 – 31.12.20178.0%2.5%3.8%

The supplier’s VAT registration

The supplier’s VAT number is looked up in the public UID register of the Federal Statistical Office (FSO). Answers are kept for 30 days, and the register is never queried faster than it allows.

Registered for VAT
The VAT on the invoice can be deducted, if everything else is in order.
Not registered for VAT
VAT charged by a supplier without VAT registration: an error, the input VAT is not deductible.
UID not found
The number does not exist in the register: check it with the supplier.
Register unavailable
The register did not answer. The report says “try later”, never a false error.

IBAN and changed bank details

Every IBAN is verified with its check digit. If the same supplier (same UID, otherwise same name) appeared earlier in your account with a different IBAN, you get a warning: confirm the new account by phone before paying.

Duplicates, sums and missing details

An invoice that matches one you uploaded earlier is flagged as a possible duplicate. Net plus VAT must equal the total, the VAT amount must match the rate, the UID needs a valid check digit, and invoice number, date and supplier must be present.

Your data

How documents are handled

  • Account, documents and results are stored on servers in Switzerland, operated by Infomaniak Network SA.
  • To read a document, its content is sent to Anthropic’s API. Under Anthropic’s commercial terms it may not be used to train its models.
  • Uploaded files are deleted 90 days after processing. The results stay in your account until you ask us to delete them.
  • Supplier VAT numbers are checked in the public UID register; only the number is sent.
  • No tracking or advertising cookies. More in the privacy notice.
Limits

What we do not do

  • We do not pay invoices. You pay as before, from your own e-banking.
  • We do not book entries in your accounting.
  • A pre-check is not tax advice and does not replace your fiduciary.
  • We cannot know whether goods arrived or a price was agreed, only what is on the invoice.
  • Poor photos can be misread. The report shows what was read, so you can compare.
