If you're a TVDE operator in Portugal using Uber or Bolt, your invoicing data flows through Fonoa — the AT-certified invoicing system that both platforms use in Portugal. Fonoa issues the invoices for your trips and provides two export formats: the per-platform CSV (which most operators already know) and the SAF-T file, which is more complete, more rigorous, and far simpler to process.
In this article we explain what SAF-T is, how to get it from the Fonoa portal, and how Frotis processes it to give you complete visibility over revenue, commissions, and margin per vehicle.
What is the Fonoa SAF-T?
The SAF-T (Standard Audit File for Tax) is an XML file format standardised by the Portuguese Tax Authority. It is used across Europe to export fiscal data in a structured and auditable way.
In the TVDE context, the Fonoa SAF-T contains:
- All invoices issued in the selected period — Uber and Bolt in a single file
- Gross value of each trip (what the passenger paid)
- Detailed platform commission per trip
- Vehicle data associated with each trip
- Complete fiscal data compliant with Portuguese tax law
How to get your SAF-T file
The Fonoa export portal lets you get your SAF-T in just a few steps. The process is free and requires no account — just your company's tax number (NIF).
-
Access the Fonoa portal
Open supplier-exports.fonoa.com/bolt in your browser. This portal is shared between Uber and Bolt — the file you receive will include trips from both platforms. -
Enter your company's NIF
In the search field, enter the tax identification number of your company (the NIF you use for your TVDE activity). Confirm that the company name displayed is correct. -
Select the period
Choose the date range you want — monthly, quarterly, or annual. We recommend monthly exports to simplify accounting reconciliation. -
Click "Submit"
The system processes the request and sends the SAF-T file to the email associated with your NIF. Delivery takes up to 24 hours — in practice, the file often arrives within minutes. -
Save the .xml file
When you receive the Fonoa email, download the SAF-T file (.xml extension) and save it somewhere accessible. This is the file you'll import into Frotis.
How to import into Frotis
SAF-T import in Frotis will be available soon, as part of the data import feature. When the feature launches, the process will be simple:
- Go to the Import section in the Frotis menu
- Select file type SAF-T (Fonoa)
- Drag the .xml file or click to select it
- Frotis validates the file, detects the period, and shows a summary before you confirm the import
- Confirm — data is immediately available in the dashboard, organised by vehicle and platform
What Frotis extracts from the SAF-T
Frotis's SAF-T parser processes the XML file and automatically extracts the following data:
| Data | Source in SAF-T | Use in Frotis |
|---|---|---|
| Gross revenue per trip | Invoice value (InvoiceLine) | Business volume, VAT monitoring |
| Platform commission | Discount/commission line | Net revenue, margin per vehicle |
| Platform (Uber / Bolt) | Issuer identifier | Filters and separation by platform |
| Associated vehicle | Registration / vehicle reference | Per-vehicle profitability |
| Trip period | Invoice date | Monthly and quarterly grouping |
This data feeds directly into the financial dashboard, quarterly VAT reports, and driver payment calculations — with no manual intervention required.
SAF-T vs CSV — what's the difference?
Many operators start by importing Uber and Bolt CSVs — it's the most familiar and most immediate method. However, SAF-T has clear advantages that make it the preferred option:
| CSV (Uber or Bolt) | SAF-T (Fonoa) | |
|---|---|---|
| Files needed | 2 separate files (one per platform) | 1 single file |
| Format | CSV — varies by platform | XML standardised by the Tax Authority |
| Fiscal data | Partial — no guaranteed AT compliance | Complete — legally compliant |
| Detailed commissions | Not always included | Always present |
| Processing | Manual mapping per platform | Automatic detection |
| Tax authority audit | Not directly suitable | Official AT format |
Our recommendation is clear: use SAF-T whenever available. CSVs continue to be supported for situations where SAF-T is unavailable or for historical periods predating the adoption of Fonoa.
