This article describes the Gov Invoice Audit Verification utility, which checks whether an archive XML file created by the Gov Invoice Archive Export still matches the electronic signature TXT file exported with it.
Overview
Gov Invoice Audit Verification confirms that an NF525 archive has not been changed since RMS exported it. You upload the Archive XML file and the Signature TXT file from the same Gov Invoice Archive Export and select Verify. RMS then shows one result: Archive File Verification Successful when the two files match, or Archive File Verification Failed when either file has been modified in any way.
NF525 is the French certification standard that requires billing software to produce tamper-evident records. Properties operating in France complete the setup described in France NF 525 & NF 203 Requirements, archive their records with the Gov Invoice Archive Export, and use Gov Invoice Audit Verification to check those archives. Auditors can also use the utility to verify an archive exported from RMS.
Please Note! RMS is highly configurable. Some Terminology, User Access & Permissions, Images, Labels, and Functions used in these articles may differ from your setup. CLICK HERE to find out more.
Use Cases
- Checking a stored archive - before relying on an archive kept on file, the person responsible for the property's fiscal records uploads its Archive XML file and Signature TXT file to confirm that neither file has changed since the Gov Invoice Archive Export created them.
- Supporting an NF525 audit - when an auditor asks to verify an archive, the property uploads the Archive XML file and Signature TXT file for the requested period and shows the auditor the verification result in RMS.
How to Access
In the side menu of RMS, go to Utilities > Gov Invoice Audit Verification.
Report Options
The Report Options panel on the Gov Invoice Audit Verification screen has one upload field for each of the two files in the archive ZIP file, and a Verify button that checks them against each other. There is no More Options panel.
| Report Option | Type | Default | Description |
|---|---|---|---|
| Upload Archive XML File | File upload | None (shows Choose file) | The Archive XML file from the Gov Invoice Archive Export ZIP file. Only .xml files are accepted. |
| Upload Electronic Signature TXT File | File upload | None (shows Choose file) | The Signature TXT file from the same ZIP file. Only .txt files are accepted. |
Gov Invoice Audit Verification Results
Gov Invoice Audit Verification does not build a report, so it has no column headers. Selecting Verify shows one message in an RMS Reporting box instead. The table below explains each message and what to do next.
| Message | When it appears | What to do |
|---|---|---|
| Archive File Verification Successful | The Archive XML file matches the Signature TXT file, so neither file has changed since it was exported. | No action is needed. |
| Archive File Verification Failed | The Archive XML file does not match the Signature TXT file because one or both files have been changed. | Extract both files again from the original ZIP file, then select Verify again. |
| Two files must be uploaded. | Verify was selected while one or both upload fields were empty. | Choose a file in both upload fields, then select Verify. |
| xml file must be of type .xml | The file in Upload Archive XML File is not an .xml file. | Choose the Archive XML file in that field. |
| txt file must be of type .txt | The file in Upload Electronic Signature TXT File is not a .txt file. | Choose the Signature TXT file in that field. |
Data Sources & Calculations
The following concepts explain where the two files checked by Gov Invoice Audit Verification come from and how the result is decided.
Archive XML and Signature TXT files
The Archive XML file and the Signature TXT file both come from the Gov Invoice Archive Export at Utilities > Gov Invoice Archive Export. Each export creates a ZIP file for one property and one period (Day Archive, Month Archive or Financial Year Archive), and the ZIP file contains two files:
- Archive XML file - named Archive_{PropertyCode}_{PeriodType}_DD-MMM-YYYY.xml, for example Archive_BH_Day_28-Jun-2026.xml. Upload it in Upload Archive XML File.
- Signature TXT file - named Signature_{PropertyCode}_{PeriodType}_DD-MMM-YYYY.txt, for example Signature_BH_Day_28-Jun-2026.txt. Upload it in Upload Electronic Signature TXT File.
How the verification result is decided
Gov Invoice Audit Verification compares the content of the two uploaded files. When the Gov Invoice Archive Export creates an archive, RMS generates the electronic signature from the entire text of the Archive XML file and saves it as the Signature TXT file. The verification then works as follows:
- If the uploaded Archive XML file matches the uploaded Signature TXT file, the result is Archive File Verification Successful.
- If either file has been changed in any way, even by one character, the result is Archive File Verification Failed.
- The file names do not affect the result. A matching pair of files that has been renamed still returns Archive File Verification Successful.
