Compliance

Every tax rule, with the screen that proves it.

The numbering, the invoice locked at the first print, SAF-T, the PGC-NIRF, IRPS and INSS, each as it appears in NUX SPACE. And how to ask the Tax Authority for the authorisation of use.

Get startedHow to request the authorisation
Every printed invoice carries a code that anyone can check.
Numbering

The number comes from NUX SPACE.

Each document type has its own prefix and its own sequence, which starts again every year. The number is given on saving, and a cancelled invoice keeps its own.

  • One prefix per document type, unique in the company: FAT, VD, NC, RE…
  • Receipts, deposits, withdrawals, transfers and expenses have a sequence of their own
  • Deactivating the invoicing series of a year locks every document of that year
  • A cancelled invoice shows as cancelled in the reports and in SAF-T
This is the reference that SAF-T declares, with the series and the number.

Original and copies

Once the original is printed, the invoice does not change.

Before the first print, NUX SPACE warns you: after it, the invoice can no longer be edited. To correct it, there are credit and debit notes. Or it is cancelled, and the cancelled invoice keeps its number.

  • At every print you choose the original, the duplicate or the triplicate, and the second or third copy
  • Every print is kept in the activity report, with who and when
  • An invoice with a receipt can only be cancelled once the receipt is cancelled
  • Purchases are not locked: the original is the supplier’s paper

Verification

Anyone can check the invoice.

At the first print, every invoice and every receipt gets a unique code and its QR. On verify.nuxspace.com you see the issuer, the reference, the date, the customer and the total, as they were saved.

  • If a value does not match the paper, the paper may have been altered
  • The code does not change, even if the invoice is printed again
  • With no QR reader, type the code: four groups of five
  • The page is served in Portuguese and in English

SAF-T

SAF-T comes out of the report.

In the documents report, choose the dates and export: to Excel, in the 30-column v1.4 sheet, or to XML. The series of each document is the prefix and the year; the number is the one printed.

  • In Excel, one row per VAT rate of each document
  • In XML, one row per item
  • Cancelled documents go in the file, with the status “Cancelled”
  • In every Commercial Management plan
Both files declare the same totals per document.
