A missing SIRET is not a detail. It is a decision waiting to happen.
B2B enrichment only matters when it advances a commercial, accounting or operational decision.
A database without a SIRET is rarely just a missing column. It prevents confident matching, billing, qualification and prioritisation.
Start with the signal, not the file
The work starts with the decision the identifier must enable: prevent a billing error, select the right accounts or secure a migration.
A system, not manual lookup
OaService SIRET matches CSV or Excel files, tolerates company-name variation and returns a confidence score. Human review can focus on genuinely ambiguous records.
The useful test
Before automating, define what must be true at the end: mandatory data, the review threshold and the next system that consumes the result.
