AutoTiers: automatic third-party auto-fill in Dolibarr via SIRET

Creating a new third party in Dolibarr is often the same routine: copy the SIRET number, open a tab to look up information on Societe.com or Pappers, then manually re-enter the company name, address, NAF code, VAT number… When you do this several times a week, the wasted time adds up fast.

That’s exactly the friction we built AutoTiers to eliminate — a Dolibarr module that does it all in one click.

The problem: manual third-party data entry

Every new customer, supplier or prospect requires creating a third-party record in your ERP. The information to fill in is always the same:

• Company name
• Full address (street, postal code, city)
• SIREN number
• NAF / APE code
• Intra-community VAT number

Without the right tool, that’s 5 to 10 minutes of manual entry per third party, with a risk of error on every field. A misspelled address, an incorrect NAF code, a miscalculated VAT number — these small mistakes create cascading problems: rejected invoices, returned mail, incorrect tax filings.

The solution: AutoTiers

AutoTiers adds a “Search” button right next to the SIRET field on Dolibarr’s third-party creation page.

How it works:

1. Enter a SIRET number (14 digits) in the dedicated field
2. Click “Search”
3. Fields are automatically filled in within seconds

All the following fields are auto-filled:

• Company name — official registered name
• Full address — number, street, additional info
• Postal code and city
• SIREN — extracted from the SIRET
• NAF / APE code — main business activity
• Intra-community VAT — automatically calculated from the SIREN

How does it work technically?

AutoTiers uses the official INSEE SIRENE API, the most reliable data source on French companies. It’s the same database used by the government, banks and social institutions.

The module works through Dolibarr’s native hook system: no source code modification is required. The installation is clean, and Dolibarr updates won’t break anything.

Technical details:

• AJAX call to the INSEE SIRENE API v3.11
• API key authentication (free, provided by INSEE)
• PHP cURL extension required (enabled by default on most servers)
• Compatible with Dolibarr 14.0+ (tested up to 22.0.2)
• Bilingual: French and English

Getting your INSEE API key: 5 minutes, free

The SIRENE API is free with no reasonable call limit. Here’s how to get your key:

1. Create an account on api.insee.fr
2. Create an application in your dashboard
3. Subscribe to the “Sirene - Open Data” API
4. Retrieve your key in UUID format
5. Paste it into the AutoTiers module configuration

A “Test API connection” button on the configuration page lets you verify everything works.

Installation in 2 minutes

Two methods to choose from:

Via the Dolibarr interface (recommended):

1. Download the module ZIP file
2. Go to Setup > Modules > Deploy an external module
3. Upload the ZIP, enable the module, configure the API key

Manually (FTP/SSH):

1. Copy the autotiers folder to htdocs/custom/
2. Enable the module from the configuration
3. Configure the API key

Why we built it

At NothingElse.app, we use Dolibarr every day. Repetitive third-party data entry was a real pain point — the kind of micro-task that individually seems trivial, but collectively represents hours lost every month.

AutoTiers was born from this internal need. We then packaged it properly to make it available to the Dolibarr community, because a module that’s useful internally is probably useful to others too.
