Frequently asked questions

Which documents can Saisix read?

PDFs, photos taken with your phone, Excel, Word and Google Sheets files, CSV exports, e-mails, e-invoices and ZIP archives. A badly damaged handwritten document may need checking.

Is Saisix ready for e-invoicing?

Yes. The Factur-X, UBL and CII invoices you receive are read from the data they carry, not just from their layout. Drop them in as they are, one by one or in a ZIP.

Can several documents be merged into one file?

Yes. Drop them in together: Saisix brings everything into a single file.

Do I need to prepare anything?

No. Show us the file you usually fill in once, Excel, PDF or other, or start from one of ours. After that, Saisix fills it in with every new document.

How do I know a figure is right?

Every figure shows the page and line it comes from. The ones in doubt are flagged in yellow before you download.

How is my usage measured?

By what there is to read and copy in each document: a receipt weighs little, an invoice a bit more, a long bank statement more still. You see the usage of each document before downloading it, and where you stand in the month.

What happens if I go over my usage?

We let you know beforehand. You can then move up to the next plan at any time, or wait for the next month.

Does Saisix use artificial intelligence?

Yes, to read your documents. Every figure can still be checked, doubts are flagged, and your documents are never used to train an AI.

Where are my documents stored?

In the European Union. They are stored with Cloudflare, in its European zone, and read by Scaleway, in Paris. They are deleted automatically.
