Bulk file checking
Upload the export from your ERP, invoicing software or CRM. TierSafe checks every record against reference sources, suggests corrections and gives you back your corrected file, in the same format, ready to re-import.
The problem
Checking a party by hand means opening the Annuaire des Entreprises, then VIES, then the e-invoicing directory, and copying what you find. A few minutes per record. For a file of 2,000 customers, that is weeks of work, with copying errors on top.
And some errors cannot be seen on a single record: the same IBAN used by two suppliers, the same SIRET under two company names, a VAT number attached to the wrong SIREN. Only cross-checking the whole file brings them to light.
The checks
Every check relies on a reference source: the SIRENE register, VIES, the National Address Base, the e-invoicing directory and the official list of approved platforms.
Matched against the SIRENE register, check digits, closed establishments and ceased companies. Damaged numbers are repaired where possible (leading zero lost in Excel, truncated SIRET), and the company is found by name when the identifier is missing.
Check key recomputed from the SIREN, consistency between the number and the company, and confirmation with VIES when the number's activity is uncertain.
Validated and normalised against the National Address Base: street, postcode, town. An address that differs from the establishment's is flagged.
Format, length and check digits of each IBAN, BIC format, country consistency between IBAN, BIC and VAT, French BIC unknown to the institutions register.
When your file contains them: routing identifier, the customer's presence in the directory, approved platform compared with the official list and with the one actually receiving.
Same SIRET under different names or addresses, same IBAN for different companies, same VAT number under two SIRENs. Insolvency proceedings published in the BODACC are flagged for information.
How it works
Allow from 20 seconds for 500 records to a quarter of an hour for 15,000. The analysis runs in the background: you can close the page, an email lets you know when it is done.
